Marine Protected Areas

Debate between Angela Eagle and Tony Lloyd

Wednesday 17th March 2021 Westminster Hall

[Dame Angela Eagle (in the Chair)]

I remind hon. Members that there have been some changes to normal practice in order to facilitate the new hybrid arrangements. I call Tony Lloyd to move the motion.

[Tony Lloyd (Rochdale) (Lab) [V]]

I beg to move,

That this House has considered the extension of marine protected areas.

It is a pleasure to serve under your chairmanship, Dame Angela. Marine protected areas are of enormous importance not only to our country and our coastal seas, but to the whole world. Our oceans are massively complicated systems and not properly understood, but we know how important they are to human life. For example, some 25% of the carbon gases produced by human activity are absorbed by the ocean. Some of that is good and some of it leads to the acidification of our seas, which is less good. We know, and the United Kingdom Government and the United Nations are in agreement, that our oceans are now at a critical point. Some 1% have protection but scientists think that a minimum of 30% require protection, to allow our oceans to restore and recover.

Sadly, over-fishing and industrial fishing are still with us, putting whole species of fish at risk. The yellowfin tuna, for example, is now endangered and could cease to exist within a relatively small number of years. The massively destructive use of bottom trawlers—those that scour our oceans, ripping up the seabed and the basis for the biodiversity that allows the fish to spawn and flourish—is doing enormous damage across the world and in the seas off these islands of ours.

We also know that the use of the oceans as a dustbin for human activity cannot go on. Plastic pollution is across our oceans. Even in the deepest recesses of the oceans, many miles down, we now find plastic waste from human activity. Using our oceans as a dump for our sewage is simply no longer acceptable. I can remember a time when the sewage boat from Manchester went out into the Mersey bay and dumped sewage—admittedly treated sewage, but nevertheless sewage—into the Irish sea. Such practices have stopped in the UK, but they must also be stopped worldwide.

Of course, there are questions about antibiotics in our seas and the short and long-term impact that will have. There are even questions about the destruction of the efficiency of antibiotics for human use. We need international action, and it is clear that we need United Nations treaties to govern the use of the sea as a resource. There is a call by scientists, for example, for a moratorium on the fishing of mesopelagic fish that lie at a depth of between 200 metres and 1,000 metres. It is up to our Government to operate internationally and to call for action at a global level.

Whether the UK has less influence today post Brexit is a moot point that we can debate on another occasion. It is a real issue, although I welcome yesterday’s announcement of the new fisheries agreement between Norway, the European Union and the UK. That is an important step forward in rebuilding the trust that has been lost recently. In fairness, the UK Government have entered an era where there are some very good examples of our international obligations in care for the sea. The protection zone, for example, around St Helena, Ascension and Tristan da Cunha is important. I think that Tristan da Cunha is the largest protected area of ocean on the planet. It was a welcome step by our country and Government.

I want to concentrate the bulk of my remarks on UK inshore and offshore seas. The cycle of carbon capture, and the maintenance of productive fishing as a resource for human consumption, depend on the biodiversity in particular of our inshore and offshore seas. Those things are most likely to have an impact closest to our coast. The sea is massively important as a source of carbon capture, and we can increase or decrease that. On an international level, in practice, before I talk about our own coast, maintaining the mangrove swamps and seagrasses—and more locally our salt marshes—is of huge importance for carbon capture; but biodiversity of the oceans is of fundamental importance.

There are good examples. The Lyme bay experiment has yielded positive results and shown what can be done, with less fishing but more fish being caught. It is a measure of how far the productivity of the oceans has declined that we can now demonstrate that we can increase the productivity of fishing with less intensive methods. When we fish less intensively there is an increase in the number of coastal fish such as pollock, cod and wrasse, which used to abound around our coast but have now become much scarcer. However, they increase once again if we take care to manage the resources around our coast.

Our coasts are not yet in the state that we would want: 25% of the UK’s seas and 40% of our inshore seas are in some form of marine protected area, but we face problems. The Government’s marine strategy report revealed that only four of the 11 indicators of good environmental status are met across our local seas. There are problems to do with nomadic fishing practices: the practices of those who come into an area without having been there before, fish and overfish, and disappear, perhaps for some years, to come back when it suits them but does not suit the biodiversity we are trying to encourage. In 2019 supertrawlers with bottom dredges engaged in 3,000 hours of fishing in our offshore marine protected areas. It is estimated that in the first half of 2020, that level of overfishing had already doubled. We have huge problems and have to take action, or the destruction of our seas will continue.

I am bound to welcome—and I do welcome—the steps that have been taken already, with the creation of the many marine protection areas around our coast. There are hundreds of them. However, we have a patchwork with different rules and regimes operating in different areas. We need to look forward to something to give greater consistency around the coastline. There are differences, it is sad to recall, between the English, Welsh and Scottish coasts. Of course Ireland is a different regime, but Northern Ireland, again, has different practices. We need consistency. I welcome the fact that the Government are looking at Dogger Bank and south Dorset for the banning of bottom trawling—that is so important because of the impact of bottom trawlers—but of course, that means that of the 76 offshore marine protection areas, only two will potentially have that kind of protection. We need a more joined-up strategy.

There has been progress, as I have said. Lyme Bay is a tremendously powerful example of what happens when we take a whole-site approach and say, “We are looking at the protection not just of individual species, but of the total biodiversity of an area.” That is important. The ban on electric pulse fishing has been another major step forward. I am a reluctant Brexiteer even to this day, but that ban has demonstrated that, where we now have the power to use UK law, we can take positive steps and move things forward. The Prime Minister spoke recently about the need to ban the vessels that “hoover up” our oceans, and he was right to call for that, but we need action to ensure that a ban comes into operation.

We need the UK Government to move forward on a total strategy for our shores and oceans. We have some of the best marine scientists in the world, and we have the capacity, as a permanent member of the United Nations Security Council, to be a leader in the demand for international change, but we need a total UK marine strategy that looks after our own shores—both inshore and offshore—and gives leadership on and commitment to ensuring that we cherish oceans around the world as something for the future, not simply as dumps for the past or as a resource to exploit and destroy.

A total international strategy would begin the move towards protecting the 30% of our oceans that we have to protect. The UK Government are committed to that, but not yet. My first call is for the UK to operate internationally to look for the kinds of global treaties that will make a material difference, give protection to our oceans, and bring sustainability for the future. My second call is for a whole-site approach to our inshore and offshore seas to join up the work that has been done across the marine protection areas off our coasts. It is tremendously important that we move in that direction.

Perhaps the most important call at the moment is for some consistency in challenging the practice of bottom trawling by super trawlers, which destroys the ocean bed. As our Prime Minster has already said in recent months, we have to stop those who would hoover up not only the fish, but the seabed, which will take many years to recreate. If we bring an end to bottom trawling in our offshore seas, we will have taken a huge step forward.

I appreciate that this is something that we have to take with care. I know that there is suspicion in the European Union that the Dogger Bank ban is being done for nationalistic fishing reasons, but we have to demonstrate clearly that it is actually being done for scientific marine protection reasons. If we can get those arguments across, we can begin to make a material difference to the biodiversity across our seas.

I say to the Minister that although the Government have done some seriously good things, which I genuinely applaud, I look forward to a joined-up marine strategy that says that we will take the lead internationally to protect our oceans, that we will take a whole-site approach to our marine protection areas, and that we will guarantee that the unacceptable practice of bottom trawling by super trawlers is brought to an end.
