I never lose an opportunity to speak about my obsession: humankind and the environment.

I always take hundreds and hundreds of pictures. I used to work for National Geographic, and they gave us a lot of film.

It's time to come together. We all have the power to change, so what are we waiting for?

I'm not an expert when it comes to technology, but what changed things for me was autofocus. I used to have to throw away half my pictures because it was so difficult to get the focus right.

The West has become the world model; developing countries are dreaming of living like us, which is impossible. They should reject our model, because it is not sustainable. Developing countries should even give us the example, but unfortunately that's not what happens.

The fact is that seven per cent of the global population emits 50 per cent of greenhouse gas emissions, and the proportions are the same for the use of energy and raw materials, meat, wood, etc. Simply put, an infinitesimal minority consumes the most and imposes damage on the overwhelming majority, while asking it to change.

Our children think our world will end. It's a tragic thing. Adults don't think that. They don't see that we are eating the planet. But we are. If you take all the biomass of vertebrates on the planet, 98% are men and their domestic animals. All the wild animals in the world make up only 2%.
