A journey into the heart of the most exceptional rainforest in the world, where a large diversity of animals and plants emblematic of Madagascar, such as lemurs, chameleons and orchid live. These very species are today among the planet's most threatened since 90% of the surface area of forest which covered the island has disappeared, half of that during the last 50 years. A fight has been undertaken very recently to combat deforestation and promote reforestation of the forest corridors between the newly created protected areas.
