Several organisations are engaged to protect our nature. I will especially mention those who work for the protection of the penguins.

Everybody knows of course the two largest organisations : WWF and Greenpeace

But there are several organisations who are engaged to one or more specific penguin-species.
Such organisations depend on donations and volunteers. You can financially adopt a penguin, donate a tree, donate money or go there and help as volunteer.
All help is welcome
