Plant 1000000000 trees!

During UNs 12th climate conference Wangari Maathai and Prince Albert of Monaco with the support of UN launched the One billion trees campaign.

In the tropics there are 3 billion billion (18 zeros) trees. So it might seem like a very small drop.

The one billion trees are intended to impede erosion and provide income.

Westerners used to suggest plantation of eucalyptus but is so thirsty it will only dry out rivers. And honey from bees living in a native trees gives a lot more profit than one eucalyptus tree.

Unlike most actions in this your are yourself supposed to plant a tree (or even better many trees) and take care of them.
