I was born into a world of just under two billion people today there are nearly seven billion of us. Whenever I hear those numbers I can honestly say… - David Attenborough

Members of the auk family, such as these guillemots and puffins... propel themselves, not with their feet like ducks, but with their wings, and they have paid a considerable price to be able to do so... Auks have had to evolve shorter, stubbier wings. That gives them a rather clumsy, whirring flight in the air, but it does enable them to "fly" underwater so well that they can outpace small fish.

This City in Ukraine was once Home to almost 50 thousand people. It had everything a community would need for a comfortable life. But on the 26th of April 1986, it suddenly became uninhabitable. The nearby Nuclear Power Station of Chernobyl exploded. And less than in 48 hours the city was evacuated. No one has lived here since

Make a list of all the environmental and social problems that today afflict us and our poor battered planet. – not just the extinction of species and animals and plants, that fifty years ago was the first signs of impending global disaster, but traffic congestion, oil prices, pressure on the health service, the growth of mega-cities, migration patterns, immigration policies, unemployment, the loss of arable land, desertification, famine, increasingly violent weather, the acidification of the oceans, the collapse of fish stocks, rising sea temperatures, the loss of rain forest. The list goes on and on. But they all share an underlying cause. Every one of these global problems, environmental as well as social becomes more difficult – and ultimately impossible - to solve with ever more people.
