The Brazilian forester Rafael Fernandes is a contented person these days. He can help to make the threatened rainforest a little bigger again. One and a half hours northwest of the São Paulo megacity, he runs a forest testing center that is jointly run by the Dutch beer company Heineken and their NGO SOS Mata Atlântica. Since 2007, they are here on a former coffee plantation, restore around a run-down forest around and plant new trees. "We recently counted 206 additional bird species," says Fernandes proudly, "and recently a puma was spotted."
