Anybody who doesn't see the impact of climate change is really, I would say, myopic. They don't see the reality. It's so evident that we are destroying Mother Earth. This is not the problem of one country or a few countries: it is the problem of mankind. We need to work together to stop this. Otherwise, our future generations will simply disappear.

Believe me, it is much harder to make peace than war.

The FARC has given up their arms. They are now a political party. They are now doing politics, which is what a peace process was all about.
