There are few places on our planet that have not in some way been shaped by humans. We’re looking at how, for better or worse, we’ve made a mark on our world, and whether it’s possible to escape the influence of us. To begin, we travel to Aldabra - an idyllic coral atoll in the Indian ocean. It’s one of the most remote places in the world, home to giant tortoises and very little human intrusion. Yet even in this largely uninhabited spot, traces of humanity can be found. Next we’ll be exploring an island far away from anywhere else, right in the middle of the Atlantic. Ascension Island is an arid landscape. But it’s also home to a lush man-made tropical forest. What lessons can we learn from one of humanity’s largest ever landscaping projects? To finish, we’ll hear from journalist Judith D. Schwartz. She explains how human influence - even that thousands of years in the making - has and can be reversed.  Thank you for listening to another series of the BBC Earth podcast.
