Most of the time, we only read bad news about the state of the forests: Tropical forests are being cleared, droughts, forest fires or pests are destroying trees all over the world. But there are dedicated scientists and environmentalists who protect and reforest threatened forests.

Borneo is a case in point: After decades in which the forest here had to make way for ever-larger oil palm plantations, the forestry authority of the Malaysian state of Sabah is now changing course. It is planting trees on a large scale to ensure the survival of the orangutans, which are threatened with extinction.

In Senegal, tens of thousands of volunteers are working on the world's largest mangrove reforestation project. This strengthens coastal protection, provides a nursery for fish and secures food for coastal dwellers.

The founder of a hip French sneaker label traveled the world for years to finally find the most environmentally friendly natural rubber in the Amazon for shoe soles.

The stories and projects from around the world show: It is worth fighting for forests. The destruction of the past can be repaired.
