The human race has walked the Earth for 200,000 years or more, but is our time on this planet coming to an end? With the threats of global warming, war and disaster looming large, are our days numbered? According to some of the experts, we're already in the middle of the Holocene extinction... But what does that mean? And how much trouble are we in??

According to the UN, humans are to blame for up to one million species facing extinction around the world.

So, what if this really is the end of life on Earth as we know it?
