>> There are few sites as inspiring as this, but also few that are quite so under threat. According to the WWF Conservation Group, global wildlife populations have plunged by almost 60% since 1970, and could fall by as much as two thirds by 2020. Reuter's Environment Correspondent Alister Doyle has been looking through the figures.
>> This is alarming, because it's not just about lions and iconic species, zebras, and polar bears, and orangutans. Life on the planet underpins everything that we have in terms of food, and it just supplies clean water so if we lose this diversity then we're in trouble.>> Hunting is partly to blame, an estimated 1,300 rhinos were killed illegally in Africa last year, for example.
ile climate change has meant fresh water species are the ones most at risk, hit both on land and in water. But the biggest factor is loss of habitat.>> The human population of growth was, we're rising, that means more farmland, more cities, more roads which is taking over just physically more area.
In addition to this, there's things like pollution and there's introductions of invasive species from different parts of the world that take over new habitats.>> The decline may not be irreversible though. A lot depends on whether last year's Paris Climate Change Deal is stuck to. And so far there are few extinctions, in fact, some species are even recovering after successful conservation programs.
> The giant panda for example was taken off the endangered list last month, with two females released into the wild for the first time.
