We are living as if we had three planets' worth of resources to live with rather than just one. We need to cut by about two-thirds our ecological footprint. For that we need one planet farming as well as one planet living - one planet farming which minimises the impact on the environment of food production and consumption, and which maximises its contribution to renewal of the natural environment

Essentially, by 2050 we need all activities outside agriculture to be near zero carbon emitting if we are to stop carbon dioxide levels in the atmosphere growing

We are a European nation - must stay one.

My advice is very simple: if you can win a small battle, it gives you confidence in the political process to take on bigger battles, and so it is very much a bottom-up grass-roots way of doing politics.

One of the jewels in the crown of Labour's time in office was the rescue of the National Health Service. As the Commonwealth Fund, the London School of Economics and the Nuffield Foundation have all shown, health reforms as well as additional investment were essential to improved outcomes, especially for poorer patients.

First, climate change is the greatest long-term threat faced by humanity. It could cause more human and financial suffering than the two world wars and the great depression put together. All countries will be affected, but the poorest countries will be hit hardest. Secondly, the costs of inaction far outweigh the costs of action.

I'm a great believer in the Arsene Wenger school of management - which is, you don't worry about the opposition, you just get your own act together.
