Degraded Chalk Stream Environments

Charles Walker Excerpts

Monday 22nd July 2019 Commons Chamber

[Mr Charles Walker (Broxbourne) (Con)]

Thank you, Mr Deputy Speaker, for calling me for my Adjournment debate this evening. I am delighted that I did not try your patience with a spurious point of order, as that really would have been naughty. If I had tried your patience with a spurious point of order, it would have been on an environmental matter, and I would have just wanted to know how I could bring to the attention of this House the fact that, on Friday afternoon, the Secretary of State refused a planning application by Veolia to build a massive incinerator in my constituency. I was delighted with the refusal, and I now hope, as do all my constituents, that Veolia will give up its plans to put the incinerator in my constituency, give up trying to put one in Hertfordshire and disappear. If I had made a spurious and bogus point of order, that would have been it.

[Sir Oliver Heald (North East Hertfordshire) (Con)]

rose—

[Mr Walker]

I will give way on that point, but I would like to get to the substantive part of my speech.

[Sir Oliver Heald]

Does my hon. Friend agree that mine was not a spurious point of order? I have seven chalk streams and I want to make a speech.

[Mr Walker]

Of course, and there was nothing spurious about my delight at Veolia failing to get its application through—it was just that I wanted to bring it to the attention of a wider audience.

[Dame Cheryl Gillan (Chesham and Amersham) (Con)]

My point of order was not a spurious one. I wanted to inquire whether the Secretary of State for Transport had indicated that he was going to make a statement on the escalating costs of HS2, which will damage the chalk streams in my area, as my hon. Friend well knows.

[Mr Walker]

I thank my right hon. Friend for alerting the House to that very important point. HS2 does pose a risk to chalk stream and riverine environments. No doubt if time allows, my right hon. Friend will bring her concerns to the attention of the House.

[Sir Oliver Heald]

I had miscounted; I have eight chalk streams in my constituency.

[Mr Walker]

My right hon. and learned Friend is such an honest and decent man. He could have misled the House that there were seven chalk streams in his area, but he has corrected the record without being summoned back—in fact there are eight.

Let us now get to the serious part of this debate, because this is a very serious matter that causes a great many colleagues on both sides of the House a huge amount of concern. The Colne; the Beane; the Mimram; the Gade; the Ver; the Chess; the Misbourne; the Wye; the Rib; the Hamble; the Bulbourne; the Quin; the Hogsmill; and the Wandle. The list could go on, but these are all chalk stream rivers that are degraded or dying around my constituency in Hertfordshire and the constituency of my right hon. Friend the Member for Chesham and Amersham (Dame Cheryl Gillan) in Buckinghamshire. This country has over 85% of the world’s chalk streams, and these streams are a unique habitat.

[Jim Shannon (Strangford) (DUP)]

The hon. Gentleman and I share many loves of the countryside—particularly a love of country sports, but also a love of the environment. Does he agree that there is a delicate balance to be struck to ensure that companies can continue to operate as they attempt to find alternative sources of water rather than chalk streams? What more does he feel can be done as a matter of urgency to protect these environmental treasures, because treasures is what they are?

[Mr Walker]

My hon. Friend is very perspicacious in his observations. I shall come to the matter later in my speech. He is absolutely right to raise that point and I hope that both the Minister and I will be able to address it, as I know other colleagues share his concerns.

The degradation of our chalk streams is one the two greatest environmental scandals of the late 20th century and the start of the 21st. Of course, the other great environmental scandal is the destruction of the marine environment off the west coast of Scotland through salmon farming—an industry that has laid waste to numerous sea lochs off the west coast of Scotland and has destroyed the native fish runs in many of the rivers that feed those sea lochs.

It is important that I put the situation in context. As I said a moment ago, we have 85% of the world’s chalk streams and most of them are highly degraded. I find it extraordinary, given our own poor environmental record, that colleagues in this House lecture Indonesia and Brazil so freely on their responsibility to the rain forests. Of course, those two countries have a huge responsibility to the rain forests, but if we cannot save the chalk streams that are literally in our own backyard, what are we doing lecturing other countries on their environmental responsibilities? Saving the world does not start with the rest of the world. Saving the world starts right here, right now, doing our bit locally with our chalk streams—think locally, act globally.

As my hon. Friend the Member for Strangford (Jim Shannon) has just pointed out, our chalk streams are literally being abstracted to death. Parts of the streams that I named at the start of my speech do not flow. In fact, a few of them barely flow at all from their source to where they join a bigger river. That is our record and it is one that none of us should take any pride in—and it is getting worse. We have had three dry years in a row. There is this myth that we live in a wet country. Certainly, parts of our country are wet but the east and the south-east are actually dry, and they are getting drier. The aquifers are not being replenished by rainfall and they are getting more abstracted, so even less water is going into our rivers.

Let me give an example from the constituency of my right hon. Friend the Member for Chesham and Amersham. In the last 10 years alone, there have been five dry events in the Upper Chess—the most stunning river, which I have the great privilege of visiting once a year as a guest of Paul Jennings and my right hon. Friend.

[Dame Cheryl Gillan]

It is always a great pleasure to welcome my hon. Friend to Chesham and Amersham, particularly at the invitation of Paul Jennings. Does he agree that Paul Jennings is one of the most outstanding advocates for chalk streams and our environment, and that he should be praised for all the efforts that he and the River Chess Association put into trying to maintain and preserve this chalk stream for our children and our children’s children?

[Mr Walker]

I entirely agree. I know Paul Jennings well; he is one of the greatest friends any chalk stream could have. He is a conservationist of the highest order, and he deserves our full congratulations and respect for the tenacity that he has shown in ensuring that the issues that afflict so many of our chalk streams are kept somewhat in abeyance on the Chess. However, I am afraid that even he would admit that he has not always been successful in doing that.

In the past 10 years there have been five dry events in the Upper Chess. In the 20 years prior to that, there were three. Drier years mean more abstraction, and things are only going to get worse. Affinity Water serves the home counties north of London, as my right hon. Friend the Member for Chesham and Amersham and my right hon. and learned Friend the Member for North East Hertfordshire (Sir Oliver Heald) will know. Affinity has no reservoirs. It only abstracts waters from the chalk aquifers—that is the only place it can get its water from. As we know, the aquifers it abstracts from are those that feed the rivers that are dying. Affinity serves 3.6 million people. In 20 years’ time that number will be nearer to 4.5 million. Where on earth is the water going to come from? If we go on as we are now, the water will come out of the aquifers and we will not have a single chalk stream running in Hertfordshire or Buckinghamshire. That is not an exaggeration; that is where we are at.

Affinity has tried, within the constraints that it is operating under—bearing in mind that it has no reservoir. It reduced pumping at one pumping station on the River Beane by 90%, which was actually a very brave thing to do. Yet that part of the river has not started flowing again because the long-term damage to aquifers that have been used and abused for the past 30, 40 or 50 years is so extreme that it may take decades to recover.

It is not just abstraction that kills rivers; it is what happens after the abstraction. If companies are abstracting water from chalk streams, they either dry them out—and that does kill them—or they reduce the flow. When there is low flow in a river, it cannot get rid of pollutants; pollutants concentrate. A river that is flowing well can move pollutants on down it, dilute them and dissolve them. This does not happen when a river is being extracted to death. So what is the next consequence of extraction? We get topsoil run-off, which just sinks to the bottom of rivers and depletes them of oxygen. It sticks to the chalk at the bottom, destroying any oxygen that can get into the chalk for the small invertebrates that live in it. Then there is phosphorus from agriculture and sewage works, which causes oxygen depletion from algal blooms and eutrophication. Basically, we have environments that cannot support life, or which support limited life, because there is no oxygen. Agricultural pesticides wash in off the fields, destroying biodiversity and wiping out invertebrates and the fly life that comes from them. Then there are the many septic tanks up and down the country that are unregulated and leaking into groundwater that finds its way into rivers. The challenge is immense.

This is an environmental crisis of a monumental scale that we are failing to address. Fundamentally, we need to reduce abstraction now. Thames Water, which I have worked closely with at times, has done that on the River Chess and the River Cray, but it wants to do more—and quite frankly it needs to do more. So what is Thames Water doing? It is making efforts to reduce leakage, and those are to be welcomed and applauded. It can introduce metering, promote water efficiency, and go into schools to educate children as to the importance of water, but, at most, these efforts will reduce consumption in the area it serves from 142 litres per day to 136 litres per day. That is just not a significant decrease. It is an important amount of water, but at 3.5% it is not going to save the day. Thames Water estimates that by 2045 there will be a shortfall of 350 million litres of water a day between the amount available and the amount needed.

There is only one game-changing solution to this crisis, and that is to create more storage capacity, which we do by building more reservoirs. I think that the last major reservoir we built was the Queen Mother reservoir for the east and south-east of England in 1974, so we have grown the population by millions but we have not put in any additional water storage. If we want to save our chalk stream rivers, of which we have 85% of the world’s resource, we really have to build reservoirs. The spade-ready reservoir that has been on the books for 12 years but has been blocked by a well-organised group of 20 people is the Abingdon reservoir in Oxfordshire. That is a game changer. If we get the Abingdon reservoir built, that starts to create the capacity we need, but at the rate the population of London and the south-east is growing, we will need more than one Abingdon—we will need two or three Abingdons. Until we start capturing water at the times of plenty and using it during dry periods like we are experiencing now, we will remain in trouble. We will be in a position where our own environmental record falls well short of where it should be, and we will limit our ability to change the way that other countries handle their natural resources, because they can look at us and say, “What on earth are you doing? You are in no position to lecture us.”

I could go on at great length, but I am not going to. In fact, I may have already gone on at great length, but this subject warrants some exploration. Finally, I would like to thank the Angling Trust, particularly Martin Salter—a former Member here—and Stuart Singleton-White, for the amazing document they have published, “Chalk Streams in Crisis”. It really is an extremely good, but somewhat depressing and sad, read. It is a call to arms. If we are to be taken seriously, we have to make changes to the way in which we approach our valuable and precious ecosystems. One of the most valuable and precious is our chalk streams, and, as I said, we have a lamentable record in this area.

--- Later in debate ---

[Sir Oliver Heald (North East Hertfordshire) (Con)]

I pay tribute to my hon. Friend the Member for Broxbourne (Mr Walker) for his remarkable and important efforts in this area.

In my constituency, we have eight chalk streams: the Upper Rhee, the Rib, the Ash, the Quin, the Beane, the Mimram, the Lea—near Bayford, where I think my hon. Friend fishes—and the Ivel. There has been some progress with the Beane and the Mimram following the WWF campaign “Rivers on the Edge”, of which Martin Salter was a strong supporter and about which we had debates in this House. There has been a 90% reduction in abstraction at Whitehall pumping station near Watton-at-Stone, and the Fulling Mill pumping station at Welwyn Garden City was completely decommissioned; that represented some success.

As my hon. Friend said, however, the condition of the northern part of the rivers is very dry. The Upper Rhee is dry, and there is a lot of concern about the Rib in the Standon area and north of Standon. The situation is similar with the Ash and the Quin. The Beane at Walkern, north of Watton-at-Stone, is short of water. There is a campaign in the constituency of my hon. Friend the Member for Hitchin and Harpenden (Bim Afolami) about the Mimram. The Lea is low, and the Ivel springs in Baldock are so dry that people regularly write to me to express their concern.

It is worth thinking about what the unique chalk stream environment is like. My constituency has small hills, between which are the chalk streams, and they create a unique environment with unique flora and fauna. Nestling in the environment provided by these ecosystems are flowers such as saxifrage, as well as small English crustaceans and the water vole. Tewinbury nature reserve is a very good place to measure the activity of flies and little creatures, and that is a remarkable thing to do. I pay tribute to the Herts and Middlesex Wildlife Trust, which does so much to support that.

[Mr Charles Walker]

I am sorry to cut my right hon. and learned Friend off as he is paying tribute to the Herts and Middlesex Wildlife Trust, but I want to pay tribute to it as well. Jeremy Paxman recently wrote that we no longer have to clean our windscreens, because there are now no insects splattered on them. There are so few insects because our rivers—and, in our part of our world, our chalk streams—have been so degraded that insects can no longer live there. Without insects, we have no fish and no kingfishers; the whole ecosystem and food chain begin to collapse. My right hon. and learned Friend is entirely right to raise that concern.

[Sir Oliver Heald]

I am grateful to my hon. Friend for that intervention. People such as Jeremy Paxman, Feargal Sharkey—he used to be a pop star but now spends his time campaigning on this issue—Charles Rangeley-Wilson, whom my hon. Friend will know, and Martin Salter, on the angling side, are dedicating their lives to trying to make people realise that this environment is as precious as the Brazilian rainforest. We have a major part of a unique environment. The water that comes up—or should do—from the aquifer is so pure, and that is a wonderful thing.

As my hon. Friend said, the problem is a mixture of abstraction; climate change, which means that in the next 25 years we will have 20% less water than we do now; and growth in housing, which means that we are trying to do more with less water. Some of the predictions that house builders and developers make in planning applications—they say that they will be able to get people to use no more than 100 or 120 litres of water a day—are just not in the real world. In my constituency, the average is about 175 litres a day. The first thing that people do in a water-efficient house is to put in a power shower, spoiling the good work of the designers. My hon. Friend is right to say that those predictions do not add up.

Soil erosion is a big issue, on which I have campaigned with WWF; it recently ran a campaign about the subject. As has been said, one of the effects of not having strong rivers is that they end up with soil in them, particularly if farming techniques are not respectful of the surrounding environment. In an area such as ours with hills that have chalk and soil on top, it makes a lot of sense to go for no-till farming, so that the soil is not blown off the tops of hills and into rivers. There is a lot that can be done.

I pay tribute to the societies in my constituency—including the Friends of the Mimram, the River Beane Restoration Association and the new organisation for the River Rib—which are trying hard to highlight the plight of the rivers. Despite the campaigns, the work that has been done and the reports in this House going back some years, we have made only a little progress against a background of deterioration. It is a question of one step forward and two steps back. I am grateful to my hon. Friend for raising this issue and giving us a chance to highlight the importance of this environment and ecoculture. Much more needs to be done.

On the Abingdon reservoir, I came into this House in 1992, and Thames Water was lobbying us then about building the Abingdon reservoir. Here we are 27 years later, and it has still not been built; it is still a few years away. We need to get on and do this. The background is against us, and action is needed.

[Dame Cheryl Gillan (Chesham and Amersham) (Con)]

It is a pleasure to follow the hon. Member for Warwick and Leamington (Matt Western). When I was growing up politically, one of my great mentors was Sir Keith Joseph. He said that one of the greatest challenges we were going to face in the future of the world was water shortages and the resulting movement of populations around the world, and I think that is starting to come very true today. My mother was always very keen on saving water. I do not know how many hon. Members will remember doing so, but she used to put a brick in the cistern to make sure that she did not use too much water when flushing the lavatory.

Aside from that, may I congratulate my hon. Friend the Member for Broxbourne (Mr Walker) on obtaining this debate? It would be fair to say that he and I have spent many a happy hour, with Paul Jennings, sitting beside one of the purest and clearest chalk streams, the River Chess, just outside London. It is not even at the end of the Metropolitan line; it runs alongside the Metropolitan line. It is accessible to the public, and it is one of those wonderful habitats and environments that can really bring people peace and tranquillity. People can leave this world behind as they sit there and, in the case of my hon. Friend, try to attract a trout to the end of his line.

[Mr Charles Walker]

The great sadness is that, to the uninitiated eye, the river looks beautiful—and it is beautiful—but as Paul Jennings would say, it is clinging on by its fingertips. Its flow is a fraction of what it should be; although it remains beautiful, its ability to support life is just draining away.

[Dame Cheryl Gillan]

I am afraid my hon. Friend is right. I came into the House at the same time as my right hon. and learned Friend the Member for North East Hertfordshire (Sir Oliver Heald), in 1992. That reservoir is not overdue, but long overdue and should have been built many years ago.

May I also pay tribute to the authors of “Chalk Streams in Crisis”? Four of the organisations that contributed are closely associated with my constituency. The Chilterns chalk streams project—a fantastic project started in 1997, prompted by the low flows in the 1990s—was expanded in 2000 to include all the rivers. It is led by the Chilterns Conservation Board, with the River Chess Association and the Berkshire, Buckinghamshire and Oxfordshire wildlife trusts. All these organisations work constantly and tirelessly to try to protect our environment.

--- Later in debate ---

[Dame Cheryl Gillan]

I think the points made by colleagues across the House have been very accurate in that we are busy lecturing other people around the world about how they should save their environment, but we are not actually looking over our shoulders at our own backyard, which is deteriorating.

The point that we have 85% of the world’s chalk streams is not lost, particularly in the south-east, because about a fifth of those are in the Thames Water region. The combination we have talked about—the climate and the geology of where these chalk streams are—means that they have the most amazing characteristics. They support special wildlife habitats and species, including things such as the brown trout and the water vole. Chalk streams are really important not just for angling, but because they are fed by groundwater aquifers. That means the water is clear, pure and inviting, which is of course why the water companies always wants to take water from them.

The hon. Member for Dagenham and Rainham (Jon Cruddas) spoke about the Thames Water briefing that was put out. He said he was struck by the predicted shortfall of 350 million litres a day between the amount of water available and the amount we will need by 2045. Population growth, climate change and environmental regulations will dramatically affect our demand and need for water. I echo the call made by the hon. Member for Warwick and Leamington, because unless we build in safeguards and build in the reuse of water, we are going to find ourselves in a desert and in a drought like no drought we have ever seen. We take water for granted in this country; it is such a shame that we have that attitude. We will have to change it if we are going to preserve our environment, particularly our chalk streams.

[Mr Charles Walker]

I hear what my right hon. Friend says, and she is absolutely right. There is nothing more irritating than to hear weather forecasters on the BBC, ITV or radio programmes such as on Radio 4 going, “Good news, it’s going to be a dry week.” or, “Good news, it’s going to be a dry weekend.” This country needs rainfall. We do not have it in abundance—and when we are not having it, we really do suffer.

[Dame Cheryl Gillan]

The point is well and emphatically made: that is absolutely right.

--- Later in debate ---

[The Parliamentary Under-Secretary of State for Environment, Food and Rural Affairs (Dr Thérèse Coffey)]

I genuinely apologise to the House for not being here at the start of this important debate, because I know how passionate right hon. and hon. Members who have spoken about this issue are. One of the joys of being the Minister responsible for the Environment Agency is seeing that the environment matters to so many people in different ways and seeing the important role of the Environment Agency. I hope, by the end of the debate, that I will have been able to persuade hon. Members and those still watching—there were four people in the Public Gallery at the start of it—on this matter, including Feargal Sharkey who is a great advocate of what we need to do to support chalk streams. The Environment Agency also has other roles and I was stopped on the way here to talk about Grenfell and some of the situations in which we are involved there. I apologise to the Chamber for that.

I have had three years in this very special role as Minister for the environment. I am very fortunate that, by and large, neither an official drought nor an official flood has been declared. I am conscious of the work of my hon. Friend the Member for Boston and Skegness (Matt Warman) on what happened recently in Wainfleet; I visited his constituency to discuss floods. The issues that have been raised about drought worry many of our farmers around the country, who are also considering the impacts of abstraction reform. I am very conscious that my constituency of Suffolk Coastal is one of the driest in the country. That said, at the Latitude festival, which was held this weekend in my constituency, there was a hailstorm, in the middle of July. Who would have thought that in Suffolk, when we are all having a heatwave? That just shows how important it is that we look after the habitat that is special to our country and to our world, while the impacts of climate change do what they do.

I will come to my hon. Friend the Member for Broxbourne (Mr Walker) shortly, but I want first to refer to my hon. Friend the Member for North West Hampshire (Kit Malthouse), who was in the Chamber for much of the debate, because he has one of the most special chalk streams in his constituency—the River Test, which many people have mentioned and in fact fished in, including my hon. Friend the Member for Thirsk and Malton (Kevin Hollinrake). The Test is regarded as one of the most special chalk streams in the country, as right hon. and hon. Members will recognise. I used to live in Whitchurch, which is 2 miles from the source of the river, so I am well aware of how special it is.

I congratulate my hon. Friend the Member for Broxbourne on securing today’s debate. It is well known in the House that he is an active champion of chalk streams and that he recognises their importance for nature and for good fishing. I will never forget the day after the 2017 election, when I was not sure if I would be reappointed to this role, when I joined him in Hampshire on the River Itchen. He had a good day’s fishing and I had a good day being shown around by the WWF and being told about the importance of chalk streams. Having lived in Hampshire, I was aware of this, but it brought to my attention some of the particular challenges that the Environment Agency regularly faces from water companies wanting to abstract more water further upstream, which has a damaging impact on the environment and the flow, as others have mentioned, as well as on the quality of fishing. That is when I met the hon. Member for Dagenham and Rainham (Jon Cruddas), who was also very passionate on this topic, which is why he contributed to the debate on 12 December 2018 on the Thames Water reservoir in Abingdon and why he strongly supported that measure.

On this matter, I have been given a very strong message by my civil servants, who are in the Box and provide excellent advice, and I am conscious that the water resource management process has not yet been finalised, but I can genuinely say, even though the Secretary of State has not yet agreed the plans, that I believe that Thames Water and Affinity Water, both of which are promoting the reservoir in their preferred plans, will receive a very warm welcome when those are put forward, so that, as many others have mentioned, we can finally get on with the Abingdon reservoir, which will do a lot of good for the people of south-east England. I am conscious that when speaking in the House I have some leeway with parliamentary privilege and that my comments will not prejudice any quasi-judicial decision that the Secretary of State might take in the future.

I return to the main topic of the debate. While chalk streams contribute to our health and wellbeing, they are principally unique habitats supporting a diverse range of invertebrate and fish species and have long been held in high regard for the quality of the fisheries they support. Only 200 chalk rivers are known globally, and it is amazing to think that 85% of them are found in the UK in the southern and eastern parts of England. It is well recognised, however, that our water resources are under pressure and that this pressure is growing as the climate changes and the demand for water increases from a growing population and greater housing need. As my hon. Friend outlined, our chalk streams are facing an unprecedented challenge, having been heavily affected by human activity, including abstraction, pollution and historic modification.

[Mr Charles Walker]

The role of Ofwat has not been mentioned yet. It has no duty to have any environmental regard. Its only interest is in driving down bills, but it should take a great deal more interest in the environment. I think we have all had enough of Ofwat in this place. I hope the Minister will take that on board.

[Dr Coffey]

I hear what my hon. Friend says. Ofwat is a champion of the consumer, and I hope that in its recent interventions with the water companies he will recognise some of the progress it has made, but I hear what he says. The Environment Agency challenged Ofwat in its initial 2019 price review over the fact that it and some of the companies that had come up with particular plans and made some good progress were none the less not fulling their environmental obligations. I am pleased therefore that my right hon. Friend the Secretary of State last week met the water companies and challenged them by saying that, while we recognised the strength of the investment they had brought to the water industry in the last 25 years, they must not forget the environment and we would continue to press them on that point. I am pleased that the Environment Agency is pressing the case with Ofwat so strongly. I hope that the next Government, to be formed this week, will proceed with the environment Bill, which will strengthen Ofwat’s powers. Who knows? There may be opportunities for even further consideration of a duty relating to the environment.

[Mr Charles Walker]

It is really important for there to be people in Ofwat who share the Minister’s passion for the environment and the passion displayed by so many colleagues here, not only in this debate but in others.

[Dr Coffey]

I entirely agree, and I hope that that will happen. I think that the term of the current chair of Ofwat, who is a doughty defender of the consumer, is due for a short extension until 2020. I also genuinely believe that any future holder of the great office of Secretary of State—if that person is not our excellent right hon. Friend the Member for Surrey Heath (Michael Gove), who has done so much for the environment and, indeed, so much in challenging water companies—will take that point into account.

--- Later in debate ---

[Dr Coffey]

I am afraid that I will not give way on that point, because I am still trying to answer the points raised by other hon. Members. We may have time at the end of this debate, but I feel there is another time for another debate on the glory of glyphosate—I am sure that I will be slandered on social media tonight for having said those words. My right hon. and learned Friend also mentioned how long it has taken to get a new Thames reservoir, and I genuinely hope we will see the plan come forward soon.

The hon. Member for Warwick and Leamington referred to his childhood roots, and in this House it is always important to recognise that, although we represent very special parts of the country, we sometimes have our roots elsewhere, which I think makes us better politicians. I appreciate that he has stayed here to talk about the impacts. He also mentioned grey water resources and how they might help water consumption. Indeed, there is a theory that the consumer is not keen on grey water, and we might need to do more work to promote the use of grey water resources in the water challenge of new homes, which I am sure he will recognise are important to his constituency, as they are to other parts of the country.

My right hon. Friend the Member for Chesham and Amersham also talked about water consumption, and I hope she will participate in the consultation. Importantly, she mentioned the challenges faced by the River Chess and the River Misbourne. It is astonishing to hear that the average consumption is 173 litres, which we need to change. I am sure she will be an active champion on that matter, as we already know she is an active champion on behalf of her constituents when it comes to High Speed 2. She referred to a number of different issues, but I am conscious that her work on the possible impacts on Ox-Cam will not have been lost on the Housing Minister, who was present for the majority of the debate—he had the wisdom perhaps to leave for my contribution.

My hon. Friend the Member for Chelmsford (Vicky Ford) told us of her intention to go up the River Chelmer on a canoe, and I hope she returns with a paddle. My right hon. Friend the Member for Newbury, who I am delighted to say is leading a review on highly protected marine areas, does not forget the rivers and streams in his own constituency. Indeed, he referred to a number of them, including the River Lambourn.

On the number of years of drought—just make it rain—it is perhaps of some comfort to the Prime Minister that, in her three years in office, she has never had to worry about a flood or a drought. Who knows how long that luck can last?

My right hon. Friend the Member for Newbury highlighted that 80% of species are invertebrates, which get ignored in our debate on the environment, and I am glad he is here today. He also talked about chemicals going into the water. That is important, and in the development of our chemical strategy over the next year, the Government will take account of how we get the balance right on chemicals, which produce much magic for our everyday lives, but we need to be very conscious of the impact they can have. Of course, he also referred to the River Kennet and to water transfer.

A number of issues have been raised about how we need to preserve these habitats, and I fully agree. The habitats in our country are so special. They are quite a small part of our British Isles, but they are so important to the world, which is why this Government will continue, in the 25-year plan, to make sure we pass on an environment that is in a better state than this generation inherited. We will do that domestically and internationally.

I thank the House. I know this has been a long debate, but one of the special things about this Chamber is that something that might seem quite parochial has huge global significance, and I am delighted to have shared this debate with so many right hon. and hon. Members tonight.

[Mr Charles Walker]

That was a great debate.

[Madam Deputy Speaker (Dame Eleanor Laing)]

Indeed it was. Very informative indeed.

Question put and agreed to.
