Trust me we wont run out of food or water for a long long time. Guess why? If we ever do run out of water, we have the sea. All we need to do is collect sea water, purify it and take all the bad chemicals out. Or we can just collect lots of rain water during winter to drink. (This is only if we do run out of food or water, which we wont)

As for food. Fruits and Plants can never run out. All they need is water to help them stay alive, we can eat Fruits forever if we get that desperate. Just get grow some Fruits in your backyard, you will never run out of food then.

Purifying that much seawater is a lengthy, expensive process, and will seriously mess with the ecosystem.  Rain water is unsafe because of how much we've already polluted the atmosphere, and if you're going to melt snow, you'd better boil it.  If in large quantities, that's still an expensive process.

If overpopulation becomes an issue, there will be food riots, and people will fight, kill, and steal any food they can find, including the stuff in your backyard.  You'd have to have a large basement and very expensive hydroponics system in your basement, providing the power is still on. 

In addition, most edible plants will not survive a nuclear winter/supervolcano explosion/asteroid apocalypse.  Besides, for all three of those, it would be lethal to be aboveground.  So you'd have to have an expensive, complicated system that provides power underground, circulates and filtrates air, and somehow provides freshwater for at least 100 years (in the event of global nuclear winter, 100,000 years).  Even longer in the case of an asteroid.

I'm not trying to be a pessimist and bring down your arguments, but you have to think realistically.

Overpopulation cannot kill anybody???

No, but it can cause lots of rioting and radical groups who believe they have to exterminate people to stop the overcrowding and rapid resource drainage.

As far as I know, we have unlimited resources for ourselves. It's not like we are ever going to run out of food or water for at least 2000 years, even more.

We're expected to run out of oil in 50 years or so.  And if overpopulation becomes an issue, we're going to run out of food, and quite possible water.

Asteroids are nothing to worry about. Earths magnetic shield usually takes them far away from Earth.

Earth's magnetic field does jack squat to stop asteroids.  We don't have a magnetic shield.  Agreed, the big ones that we should worry about have slim chances of occuring, but chances none the less.  It's best if we eradicate any probability.  Some of the smaller ones have much better chances, though; there's a small one somewhere out there that has a 1 in 66 chance of hitting. 

Scientists everyday are working out ways to stop Asteroids. In 20 Years I think we will have found a way to stop asteroids, or something to make them much smaller, so it wont blow up the Earth.

Remember when they said the world was going to end when the clock hit year 2000?

That will happen in 2039 unless we switch completely to 64-bit processors in our computer systems.

Remember when they said the Devil will return and kill us all in 6/6/06?

That's just stupid people who think special numbers (666 is incorrect anyways, the real number is now believed to have been 616 due to translation errors.  It very well could be 919 since the book of Revelations was supposedly based on a dream)  correspond to events on the calendar.  Pure superstition, no scientists or anything thought anything would happen.

Scientists have said themselves they always like to prepare for the worst situation, not the best. So just because they say something, doesn't mean its true.

12 Monkeys is my favorite science fiction movie. The genre isn't very strong, you're definitely right. I think it's mostly because it's about fantasy and that means it can be inconsistent.quiglythegreat
