I live in Italy, the Po Valley I live in was a marshland with lots of centenarian trees. Since Roman times marshes have been drought and most of the forests were chopped to make room for agriculture (and to build Venice, which sits on millions and millions of trees).
I recently went to Portugal, where most forests have been chopped and substituted with huge eucalyptus or cork oak monocultures.
The same goes for France, Germany, etc.
We destroyed our environment so we could have progress. Now we understand that the environment is precious and must be taken care of, so it's up to us to pay other countries to preserve their environment. This money will eventually be used to buy "progress" and end on our pockets once again so it's not even a bad deal economically speaking, it just takes the will (which is lacking almost anywhere).
