Around 250 million years ago our world was a very different place. Rather than the different continents we know today, there was only one giant land mass - Pangea - covered with plants and animals. But then something went horribly wrong. Over a few million years, more than 95 per cent of all species on the early earth were wiped out in an event known as the Permian mass extinction. So what caused it? One researcher who thinks he might know is Mark Sephton from Imperial College London and, as he explained to Kat Arney, this wasn't the first time that our world has come to the brink of disaster...
Just too many paths leading in the same direction. What people constantly fail to see is that you don't need 'conspiracy theories'. Exchange them for short sighted 'Self Interests' and you will get the world we have, The more 'power' you have, the more your self interests will 'weight' into your favor. And that includes all political ideals, from our western 'representative' democracy, to Russia's even more questionable variant, to outright dictatorships. We are in dire need of a real democracy, but we don't really want it. Shortsighted self interests will stop us there too I expect. yor_on, Sun, 29th Mar 2015
Yes RD, another take on the same problem. That our 'infinite Earth' is getting smaller by the minute.
On the point of climate change, and the polar ice caps in particular, if the polar ice caps were to diminish enough to slow or even stop the oceanic current, what might result from still oceans? Don_1, Wed, 3rd Jun 2015
