I thank my hon. Friend for that intervention.
Trees have been mentioned only briefly, but I am a great tree person, and I must speak up for them. We must encourage partnerships to reduce deforestation. We need to work with countries such as Brazil to stop the cutting down of rain forests, which is the single largest contributor to the release of carbon. Reducing cutting will have an enormous impact on climate change, and will also maintain our biodiversity—and placing a value on the benefits of biodiversity is part and parcel of the climate change debate. In that context, I am pleased that the Government are now talking about the importance of nature capital. Maintaining tree cover, whether it is done in Brazil or elsewhere in the world—including on the Somerset levels—will reduce flooding and soil erosion, aid soil maintenance, and give us cleaner water.
The Pope has called for increased action. We should bear in mind that not everything can be achieved in a stuffy room in Paris; a lot can be done there, but we in the House can do a lot as well.
I will not, because I am about to end my speech.
I urge you, Mr Deputy Speaker, to join me and play your part in cutting emissions by running your washing machine on a very low heat. I do that, and the washing is still clean. You can also reduce your wash time, and you can turn down the heating or not put it on at all: my husband hardly ever lets me turn ours on. You can also use public transport, and grow your own food. Look after your soil!
Those are all things that we can do at home, but Paris is important in the long term. It is essential that the Government work to get the very best that they can out of it, and that we continue to lead by example.
