I watched a two hour show yesterday on possible causes of the end of life on Earth. Very interesting and after all the possible causes it really came down to the most likely one was the human race.
Also according to them in 2029, Apothos, a large meteor will pass close enough to the Earth that it will be between Earth and our communication satellites. Then it will return in 7 years and they don't know what to expect. If the Earth's gravity affects it enough, it could crash into the Earth on it's return and that would effectively end life on the planet. All of this was ways that life here could come to an end, but all were very possible though some were also very unlikely to happen. I thought it was an interesting show as it wasn't Science Fiction, but laid out real things that could come to be.
