Madagascar's lemurs - the world's most threatened primate - could be saved from extinction by eco-tourism, conservationists say. The big-eyed fluffy creatures are unique to the island but their numbers have declined dramatically in recent years. Now researchers have unveiled a survival plan that combines tourism with increased conservation efforts.
Millions of years ago, one area of reefs managed to survive a major coral extinction. The Coral Triangle in the Western Pacific is still the most biodiverse region in the world. And that is why leading marine scientists are deploying the latest in 3D mapping technology to uncover the secrets of what allowed the coral in this unique area to survive.
