Seven Worlds, One Planet. New David Attenborough series on the BBC

Catch up with David Attenborough new series. The first one is about Antartica and the impact humans have had on it. Click on the link to view on BBC iplayer. Antarctica was only discovered 200 years ago, but humans have had an enormous impact in that time. The whaling industry killed over 1.5 million whales here, taking many species to the brink of extinction. But since the ban on commercial hunting in 1986, whales are making a remarkable comeback. In addition, the Antarctic treaty is exemplary in demonstrating that countries from around the world can unite to protect wildlife. However, due to climate change, the Southern Ocean is warming and sea levels are rising. Perhaps more worrying is that a warming of the coldest region on earth will have profound effects on global weather patterns. Although Antarctica is far away, what happens here will affect all of us.
