Lords ChamberMy Lords, I strongly support what the noble Duke, the Duke of Wellington, has said and many important points made by other Peers. I have only one point to make on top of the others: there has been no real improvement for so long now—certainly, not very much since 2016. In 2020, only 40% of waterways were classified as being in good health—meaning as close to their natural state as possible.
We all know that a major cause of this is sewage. In 2020, raw sewage was discharged more than 400,000 times over a period of 3 million hours, and this water, as the noble Baroness, Lady Jones, has claimed, brings huge quantities of microplastics as well. As the noble Lord, Lord Cormack, said, sewage is not the only cause: some 40% comes from run-off from agricultural industries.
The point is that, since legislation was passed and the Environment Agency has been in charge and responsible for it, there has been no real improvement. This may be due to lack of proper funding, but the fact is that it has not been able to bring about any real change. We now have the worst quality in Europe, with England comparing very badly with Scotland, where 65.7% of surface water bodies are in good health. We know this—it has been repeated time and again, and the environmental Ministers acknowledge it.
The question is: how can we ensure that real change takes place soon? Including Amendment 4 is where we must start in ensuring that good quality water is a goal that we fully intend to achieve. We must use this Bill to ensure that we achieve it.
My Lords, it is a pleasure to be speaking to this amendment moved by the noble Duke, the Duke of Wellington. During the past two years, many of your Lordships have raised the issue of the quality of the water in many of our iconic rivers and given very graphic examples of where pollution has been discharged, untreated, into our waterways. We have heard about chicken manure being discharged into the River Wye, previously one of the most beautiful rivers on our island. At Second Reading, the noble Earl, Lord Shrewsbury, reminded us about the discharge of raw sewage into rivers. As one of her first duties, the newly elected MP for Chesham and Amersham, Sarah Green MP, has visited the River Chess to hear from the local action group about the pollution of it.
During lockdown, with local authority swimming pools closed to the public, those who were able took to what has become known as wild swimming in the sea and rivers. I am assured that this is extremely invigorating and refreshing, but probably not so if you are encountering severe pollution on the scale that we have heard of from the noble Duke, the Duke of Wellington. Biodiversity is severely affected by the pollution in our rivers.
The treatment of sewage is the responsibility of the sewerage and water authorities. It is not sufficient for them to claim that new housing developments have overwhelmed their treatment plants and they have no choice but to discharge sewage into our rivers and sea. We have heard recently of the public disquiet about the Government’s proposals to change the planning laws. Often, statutory consultees respond to local authorities with “no comment”, but often they do not respond at all. Perhaps this is an issue of resources, with Defra cuts to the Environment Agency filtering down to the front line. The water authorities should be obliged to respond to consultation on proposed housing developments, especially where there is insufficient capacity in existing treatment plants to cope with the current, never mind the future, demand.
All noble Lords taking part in this debate have expressed concern on the issue of water quality. The Government must take it seriously if we are to restore the quality of the water in our rivers to enable biodiversity to increase, even if it is unlikely ever to reach its former levels. As the noble Baroness, Lady Young of Old Scone, and others have flagged, we will return to this in later amendments. This is a very serious matter, as my noble friend Lord Teverson and the noble Lord, Lord Cormack, said, and we fully support the comments of the noble Duke, the Duke of Wellington, in moving this amendment and look forward to the Minister’s response.
My Lords, I would like to speak in favour of Amendment 10 in the names of the noble Lords, Lord Randall and Lord Taylor. The effect of light pollution is intrinsically part of the existing four priority areas for which environmental targets will be set, but it is not mentioned in any of the actions identified in the Bill to remedy or mitigate the underlying issues raised by these targets. Hence a separate target to reduce levels of light pollution is necessary and will not be difficult to implement or measure.
I declare my interest, being a vice-chair of the APPG on Dark Skies, like the noble Lord, Lord Taylor of Holbeach, and as the grandson of a knighted astronomer. Light pollution is relevant to human health, nature and wildlife, energy consumption and thereby greenhouse gas emissions. First, on health, epidemiological studies conducted in the United States have identified poorer sleep and anxiety disorders emanating from outdoor illumination, affected physical and mental health and well-being. Constant light is a well-known method of torture. Secondly, there is the effect on nature and wildlife. A review from Nature magazine in 2018 concluded that
“early results suggest that light at night is exerting pervasive, long-term stress on ecosystems, from coasts to farmland”
and
“waterways, many of which are already suffering from other, more well-known forms of pollution.”
The article then mentions a UK study on the timing of bud opening in trees, also raised by the noble Lord, Lord Randall. The study demonstrated a rate of acceleration “similar to that” now “predicted for … global warming”.
A Defra report in 2019 showed a sharp decline in insect numbers, with a 31% drop in insect pollinators between 1980 and 2016, and a 60% decline in the 2,890 priority species from 1970 to 2016. The State of Nature 2019 report by the National Biodiversity Network identified urban areas as particularly affected. In 2017, a paper from Nature highlighted the connection between light pollution and pollinating insect species, suggesting a threat to world food production.
Thirdly, there is the additional and unnecessary fuel consumption associated with aggressive illumination and the extra burden on greenhouse gas emissions. The reason for illumination that is so often given is that of safety. A study by the London School of Hygiene & Tropical Medicine found that crime and road collisions do not increase in dark or dimmed areas.
Measuring light pollution is simple, as mentioned by the noble Lord, Lord Randall, with the use of a system produced by CPRE that can form the basis of monitoring change. Let us use this opportunity to acknowledge and deal with this important area, as encouraged by the Government’s draft environmental principles, encompassing both precaution and prevention. Measures to remedy the problems are not rocket science but clearly achievable through the strengthening of the planning framework, the reform of planning permission processes, the strengthening of statutory nuisance provisions, education, and technological developments. We can also learn from examples of measures taken in countries such as France and Germany.
Surely the amendment has a necessary and worthy place in this important Bill.
My Lords, I shall speak in favour of Amendment 10, to which I have added my name, and I support other amendments in this group. I declare my interest, as others have done, as a member of the APPG for Dark Skies. The noble Lord, Lord Randall, has made the case for his amendment very eloquently, as has the noble Lord, Lord Taylor of Holbeach.
When I was a child—this was a while ago—I was brought up in Bristol. Like all children, I was fascinated by the moon, which shone in the sky. Man had not yet ventured to the moon, which I felt was a distant, magical planet. Although we lived in a city, it was possible to see the night sky. Streetlights were switched off before midnight, probably at about 11 pm. There was much less human activity at night in those days. I was therefore able to concoct wonderful stories in my imagination about the man in the moon and the shadows on the moon’s surface.
Roll forward to today, and the map of the country often shown on news bulletins is of a land illuminated by streetlights that are not turned off. The areas where darkness prevails are few and far between. It is impossible for a child living in an urban area to investigate the sky and see the stars twinkling in the light reflected from the moon.
To move from the emotional view of light pollution to the detail of it, it is impacting our species and ecosystems, and increased artificial light at night is directly linked to negative impacts on energy consumption, human health and wildlife such as bats, insects and plants, as others have referred to. Ten years ago I could walk down the lane at 10 pm and bats would be swooping around overhead, consuming gnats and other flying insects. Today it is very rare to see any bats overhead at night. There is a wealth of information about the effect on birds and insects of artificial light, and others have made powerful speeches about the impact of light pollution on night pollinators and on feeding cycles.
My neighbour has a telescope in their upstairs window to see the stars. How very lucky we are to live in a dark area—the only light pollution that we suffer is from Advent to Epiphany, when the church is illuminated by floodlights—but over 90% of the UK population are estimated to be unable to see the Milky Way from where they live. To my mind, that is a severe limit on their ability to observe and wonder at the world that we live in, as well as having a devastating effect on the ecosystems and biodiversity of the nocturnal environment. The night-time economy is often referred to as a good thing. It is time that the animal, insect and plant nocturnal economy was given protection to ensure its survival. I fully support the amendment from the noble Lord, Lord Randall.
My noble friend Lord Teverson spoke eloquently about the long-term biodiversity target, both onshore and offshore. I share his comments and his concerns about our territorial seas, the marine ecosystems and seagrass.
The noble Baroness, Lady Bennett of Manor Castle, urged us to reduce consumption of resources rather than improve efficiency. To make a difference, both will need to be high on the Minister’s agenda.
Tree planting, which we have debated many times, is essential to carbon sequestration, habitat protection and improving flood alleviation. Protecting our native trees from diseases imported from other countries and those carried on the wind is essential to maintain a steady increase in the number of trees. The noble and right reverend Lord, Lord Harris of Pentregarth, raised tree planting.
The amendment from the noble Baroness, Lady Bennett of Manor Castle, on soil quality is really important; the subject was raised on Second Reading. The noble Earl, Lord Caithness, has also supported this. If we do not get the soil quality right, we will not move forward.
We are all aware of the contribution that cattle make to agricultural emissions—currently accounting for 60%. The Committee on Climate Change recommends that the Government implement a 20% reduction in the consumption of meat and dairy; most speakers referred to that. Can the Minister say whether the Government are preparing a strategy to ensure that this 20% reduction is implemented? Perhaps this will be through raising awareness with the public of the effect on the environment of meat and dairy consumption.
This has been an important and fascinating group of amendments. I look forward to the Minister’s response.
My Lords, I thank the noble Lord, Lord Teverson, for introducing this important debate and all noble Lords who have contributed to the hugely important spectrum of issues raised this evening.
I thought the noble Lord, Lord Teverson, made a significant point that repairing our marine biodiversity is as important as rebuilding our land-based biodiversity. But it is true that, as it stands, the Bill ignores the marine environment completely. I agree that that needs to be addressed.
Sadly, our seas and oceans are increasingly polluted. Plastics and microplastics, chemical fertiliser, run-offs from agriculture and, as we debated earlier, sewage discharges, are all damaging the quality of our seas. We are killing off our coral, creating ocean dead zones, and allowing excess algae blooms to suck the oxygen out of our water. The effects of this are damaging to both marine and human life, but, as the noble Lord, Lord Teverson, argued, if we act now, reverse those trends and encourage new growths of seaweeds and seagrasses, the oceans could be harnessed as a positive source of carbon sequestration in our climate change strategy. There is everything to fight for.
In his Second Reading response, the Minister mentioned the blue belt around our overseas territories. Of course this is welcome, as is the growth of marine protected areas around the UK coastline, but there is so much more we should be doing. The current marine protected areas still allow damaging seabed extraction and fishing. I hope the Minister can confirm that the recommendation of his colleague, the noble Lord, Lord Benyon, that there should be a string of highly protected marine areas will be implemented in full.
Sadly, so far, the Government have seemed reluctant to legislate to ensure that any future marine protections are legally enforceable. That is why we would welcome the inclusion of robust marine biodiversity targets in the Bill. Our experience with the Fisheries Bill last year was that the Government were not prepared to put sustainable fishing at the heart of the Bill. As a result, the charity Oceana has reported that, post Brexit, only one-third of the UK’s key fish populations is in a healthy state, with bottom trawlers and supertrawlers causing particularly damaging effects on the marine environment. So, if not now, when will we see action on these issues?
