In France's overseas department of French Guiana, the Amazon rainforest covers 90 percent of land. It's teeming with wildlife, but this unique biodiversity is in danger. Researchers and locals are doing their best to protect it, like in Favard, where the village healer passes on his knowledge to the younger generations and educates tourists on the need to protect the forest. Meanwhile, entomologists list different species of insects, a titanic job as this knowledge is still in its infancy. Finally, researchers are trying to understand what's driving the decline in sea turtles.
