How Long Will Earth Survive?

The Earth will go on forever. It will never "end" in the sense that it breaks up in little bits and then evaporates into nothingness. Even if our Sun burns out, explodes, implodes, creates a black hole, and sucks it in, it will still exist. As far as human life on the Earth, that's a different story entirely. I think people are fully capable of causing catastrophic damage to other people. But I don't think that any of the doomsday scenarios would cause humans to become extinct altogether. A nuclear winter would cause mass devastation, but people could survive. The climate changing due to melting ice would really cause the weather to become unpredictable, but people would most definitely survive. A lack of resources, like oil and fresh water, would be overcome easily by people if they were forced. The real problems that the human species faces isn't from other humans, even though that's always the more popular theme for movies and fear mongerers who want you to purchase their "energy-saving" light bulbs to fund their private jets. What threatens humans the most is that the Earth--and universe in general--is never at a standstill. No matter how much TP and water we save from not flushing, or how many lights we cut off, or how many hybrids we buy, the Earth will STILL go into another ice age. The Earth will STILL go into an extremely hot period. The continents are still moving and will continue to move. They will circle around the globe, collide again, and create new mountain ranges and new wonders and new oceans. And there's not a thing in the world we can do about it. Humans may be able to break from oil and stop cutting down so many trees, but as the years pass, many trees will naturally grow and oil and gas will continue to be made naturally. I think that when we ponder the end of the world, what we're really thinking of our are children and grandchildren and what life will be like for them. Well, it's my personal opinion that those environmentalists are looking to scare people with their doom and gloom scenarios. And it's a fact that they're all wrapped up in big business, earning massive amounts of money by promoting their planet-saving products. We will survive as long as the Earth lets us. Hopefully, we won't suffer the dinosaurs' fate. :)

my daughter was just talking about this yesterday. She is 17 and she said it is not fair that the world ends before she is 20 years old! Then my son got angry - he is only 15 years old - and said it was all garbage and he didn't want to talk about it anymore

The world will be destroyed either when the sun goes out or because of us humans will destroy it. I doubt it will be die on dec 21 2012 even though people might die doubt the earth will be gone. But like I said we will destroy the earth or when the sun goes out that will be the end.
