I am really pleased that this debate is happening today and that we are able to have a serious discussion about the effects of climate change on biodiversity. We have to be realistic: what is happening now is absolutely unprecedented in known human history, given the rate at which we are losing wildlife, biodiversity and insect life, and ultimately this is extremely damaging to human life itself. There has to be a much more thought through process of linking up all the environmental consequences of our lives, of industries and of the pollution that takes place.
Conferences such as COP15 are very important because they are a way of bringing people together. They are a way of trying to persuade all countries that the issues of CO2 emissions and their effects on climate change and global warming are absolutely huge, and that something has to be done about them. However, that is not the whole story, because to some extent we are guilty of exporting our pollution and our emissions elsewhere. This country, most of Europe and some parts of north America have increasingly strict environmental protocols—on river waste, air pollution and so much else—which I absolutely support and endorse, but the effect of that is to shift manufacturing and polluting activities somewhere else.
That means we are not actually improving the global environment; all we are doing is shifting the pollution to some other place.
I hope one conclusion from this debate—I am sure the Minister will understand all this—is that we have to be very active internationally in trying to bring about a more sustainable world everywhere. This is about joined-up actions being taken by the UK Government. A very lengthy letter sent to them recently talks about the need for joined-up action by the British Government, as well as reducing the
“ecological footprint, domestically and globally”,
ensuring that
“biodiversity loss has been halted and reversed by 2030, against a baseline of 2020”,
and creating
“robust and well connected natural infrastructure across all UK nations”,
as the hon. Member for Brighton, Pavilion (Caroline Lucas) pointed out in her excellent contribution to the debate. If we do not have that sense of joined-up thinking, we will be missing the whole point altogether.
There are many issues we could discuss today, but the one to which I want to draw attention first is water pollution in this country. I grew up with the idea that, somehow or other, the appalling levels of pollution created in all of our major rivers in this country by industrialisation and the industrial revolution of the 19th century were gradually becoming a thing of the past and that we were beginning to clean up our rivers. Yes, rivers in some places are a lot cleaner than they have ever been. The Thames, just outside, was biologically dead at one time, but it was eventually—very slowly—restored quite considerably. There used to be a huge tank in County Hall showing all the varieties of fish now found in the Thames.
Sadly, for many of our rivers, the trend is now going in the opposite direction, as the water companies routinely discharge raw sewage into our rivers, which obviously has a devastating effect on fish and natural life, and clearly becomes dangerous for the rest of the population as well. Yesterday, right on cue, Thames Water sent a very long letter to all of us who represent constituencies within its area telling us how much it is going to do to try not to pollute rivers, mainly the Thames, in the future by better management of the tributary rivers, the drainage system and so on. That is good, if it is actually going to do it, but its record, like those of most other water companies, is pretty terrible. At the same time, the water industry is dragging vast profits out of the water supply and allowing pollution levels to get so bad.
I do think we have to be extremely tough on the water companies and their management of rivers. That includes managing rivers upstream, as well as managing our paved-over areas in our urban communities to deal with the flooding issues in this country. It is not as if any of this is not known, but this is a question of joined-up thinking between planning and local authorities, water suppliers and central Government to try to achieve something much more sustainable.
If we are to deal with increasing levels of unusual rainfall, that obviously means better management of rivers. It is not all going to be done by flood protection. It would be done much better by upstream planting on rivers in this country, which to some extent has been
done in Somerset and the west, and the use of the floodplains as what they are intended for—the key is in their name—so that we end up with less flooding and damage to property through better environmental management of those water resources. This is about the biodiversity of our river systems, which is central to so much of our thinking.
There is a debate everywhere about rewilding. Anyone who has read Isabella Tree’s excellent book about Knepp, and the way that that rewilding took place, knows that initially, many of the neighbouring farmers objected to it and said that she was creating a scruffy place that had lots of weeds on it and was damaging their crops and so on—I have heard many of these arguments for a very long time. She reports in a fascinating section of her book that eventually, after the rewilding had grown a great deal and become much more biodiverse, crop production rates went up because of the high levels of pollination by higher levels of insect life surrounding those farms. As the right hon. Member for Epsom and Ewell (Chris Grayling) said, there is an interesting phenomenon of joined-up thinking on farming, because it is about the biodiversity surrounding crop production as well as the preserved areas that the hon. Member for Brighton, Pavilion talked about in her excellent contribution. We must think about that aspect.
This is also about how local authorities behave. I have the honour of representing my constituency, which I believe is the smallest urban constituency in the country and, I am pretty sure, the most densely populated in the country. Most people in my constituency have no open space of their own whatsoever, not even a balcony. Bringing up our children in that atmosphere, it is not easy to get them to understand the interaction between human life and natural life, because they live in an entirely concrete environment. What we do in our schools and our parks is important, as is the message that those young people get.
I have always visited each of the primary schools in my constituency as often as I can, usually once a year, and I have been to two primary schools and one secondary school in the past week to hold a discussion with students about their views on the environment. These are children growing up in a very urban environment, but they absolutely get the connectivity between the natural world and themselves, and they get what is possible in the small growing spaces that they have in those schools.
Yesterday morning I was in Ambler Primary School near Finsbury Park. It is a very densely populated urban area, with high levels of traffic around it. We were talking about biodiversity, growing flowers and so on, and one student asked me what I meant when I said that we should not be cutting grass too short. I was explaining about wildflowers and biodiversity, and he wanted to know whether that included football pitches. I explained that there had to be a balance between keeping grass on football pitches the right length and growing flowers and other things—it is a serious practical question if your interest is mainly in football.
Winning people over to these arguments is so important, and today’s debate will help us to do that. We must also encourage local authorities to have more permeable surfaces and fewer car parks with impervious layers, and to end the appalling practice in many parts of the country of paving over front gardens to park cars, when
those front gardens are an important point of nature. Indeed, paving them over increases the danger of flooding, and thus the pollution of rivers further downstream. Some local authorities have done well on that. For example, Rotherham Council has done an excellent job in ensuring a huge level of biodiversity on all its roadside borders, and a number of other councils have done exactly the same. We should support them in that.
Those are the things we can do ourselves, through farming policy, the use—or non-use—of pesticides, and building up a sense of biodiverse resilience, which in turn will protect endangered species. Sadly, as the right hon. Member for Epsom and Ewell pointed out, the hedgehog is not far off being an endangered species. Obviously I hope its population recovers, but it seems to be recovering in urban rather than rural areas. That is deeply disturbing and suggests that it is due to a combination of farming practices and dangers from roads, whereas urban areas seem to be maintaining or even recovering their hedgehog population. We can do an awful lot, and we must bring up our young people to understand that.
I pay tribute to teachers in schools who do their best to achieve that. During a visit that I made recently to another local school, Newington Green Primary School, there was another brilliant set of children who were concerned about these issues. Older students, such as those at the Arts and Media School Islington, who are preparing to do their GCSEs and later their A-levels, believe—this view has also been put forward in the House—that there should be much more environmental education at all stages of our education system, so that children grow up understanding such things.
To add to what has been said already, the loss of biodiversity on a global scale is huge. The number of animal species that are becoming extinct year on year is increasing fast, and there will come a time when the elephant, the tiger, the lion and so many other large species will be on the danger list, as well as very many smaller species that are almost extinct at the present time. As such, I agree with what the right hon. Member for Epsom and Ewell said about changing the story and the narrative.
In some places, such as the Indonesian, African and Amazon rainforests, there is a huge economic advantage to be gained from selling tropical hardwoods. On the way to get one tree—iron tree, mahogany, or whatever else it happens to be—the whole forest around it is destroyed or, in the case of the Amazon rainforest, wantonly burned down in order to create the short-term advantage of growing soya for a few years, leaving a virtual desert behind. I discussed that issue with a lot of environmental campaigners and others from Brazil, both from Rio and from the Amazon, during the COP in Glasgow last year, and the similarity of views between those from urban Rio and those from the Amazon area was very interesting. The commitment now being made by the putative and hopefully next President of Brazil, Lula, to end all the destruction of the rainforest and promote sustainability there is welcome. I hope he gets elected and is able to achieve that goal, because it would be an enormous step forward.
It is no good western countries lecturing the poorest people in the poorest parts of the world about the need to protect their environment, because we believe it is the right thing to do, when they cannot feed their children,
do not have a proper education system, do not have a health service, and are living in levels of desperate poverty. Something else has to go with it. Eco-tourism does help, as do sustainable agriculture and our purchasing practices and powers, but this is also about bringing people on board. If we just fence off an area and say, “This is preserved, and we are going to put armed guards in it to protect the animals that may become extinct”, we are not sending a very good message to the people who live in that area. The most effective conservation, whether marine or land conservation, is done with the participation, support and involvement of the entire community that lives locally.
I will give one example. In Mexico, the turtle on the Atlantic coast was rapidly depleted in numbers and was not far off extinction. There was an idea to create a protected zone for sea turtles, with lots of guards to prevent people from stealing turtle eggs. What would have happened then? Corruption would have come in, somebody would have started stealing the eggs, and so on. What they actually did was recruit all the turtle hunters to become turtle protectors as a way of making money out of visitors going there. There is nothing like a poacher turned gamekeeper to look after a species that was at great risk. Conservation can work if people bring the population along with them; it does not work if security companies, armed guards and everything else are sent in. It is so important to achieve that more universal buy-in.
I am delighted that we are having this debate. We have to ensure that the generation going through school—the next generation coming up—understands that our lives and the survival of this planet depend on how we interact with nature. That means bringing children up to understand that insects, wildlife, and wild places are not their enemies—that we have to live alongside nature, not destroy it through our activities and our greed. They will then get the message about connectivity: that when a person drops a plastic bag in a river, it ends up in the sea, and we end up eating that plastic with the fish we consume. It is about conserving and preserving the natural world and the environment. Of course, that includes the big global conferences and the international agreements, but environment is basically a state of mind: whether we live with nature, or destroy it and see it as something solely to be exploited. Today’s debate is a good example of how we can advance both of those agendas at the same time, ensuring that we get the international agreement that is essential, but bringing that debate into all the other actions of our lives and all the services that are administered by the public in this country.
