Now, you can go to Península Valdés and find that the whale population there is growing year after year, people can see them from their windows. In Iberá, where yaguaretés were extinct for over 70 years, there's now a population of 35 and growing, after being reintroduced just five years ago. As for rainforests?

We've becoming very, very good on restoring them. Natural environments, when given space and time to heal, can return to that they were. And after all, all natural enviroments are managed by human societies. It is up to us to implement a good management, un buen gobierno.

I firmly believe our children and grandchildren will see a restoration of Earth like never before.
