Trees are all around the world - they provide shelter, food and wood.
Forests also play a crucial role in absorbing carbon dioxide and thus regulating the global climate. People have already deforested large swaths of the world, with consequences for ecosystems, plants and animals, and even humans themselves.
The Romanian Carpathians are one of the few remaining pockets of old-growth forests in Europe. But the future of these forests is at risk due to logging and environmental degradation. Greenpeace has started documenting the forests with the hope of raising awareness before it's too late.
