As humans become more numerous and our resource demands begin to exceed what we have, a given group will have a few options:
1) Technology - create more food using less space, and do it faster.
2) Tighten the Belt - consume less food.
3) Shoot your Neighbor - neither of you have enough food, but if he does not need to eat maybe you will. Who knows, maybe he tastes good too.
Earth will not be able to sustain human life on it's present course. No one can argue with this. Either something has to be done, or we will face a real threat of extinction within our grandchildrens lifetime. The nearsightedness of governments has prevented population control on a scale that could have an effect. The oil industries fighting alternative fuel has hindered the production of safer vehicles that would save our reserve of fuels and keep the air cleaner.
Earth will be able to sustain human life, because it will balance out when critical mass is reached. Even if you remove the possibiity of people being killed, some will starve before others, leaving enough food for the remaining people to survive. Extinction is not a danger.
What happens when we run out of oil? Well... cars will stop moving. Some electricity production will go down, cheap plastic toys from Japan will now be really expensive. Life will go on when your BMW will only roll downhill, and I doubt that our skin will be falling off our bones from the toxic air.
Many scientists theorise that this is planetary self preservation; we are out of control, so nature is dealing with us.
This is either untrue, or many scientists are idiots. Nature is not intelligent, it is just a concept. We will deal with ourselves, and come to equilibrium just like every other organism on the planet has managed to do.
I was pretty general about this, because being specific about this would take up way too much space. What can we do to prevent the destruction of our species? Why are so many people convinced that we are not in any danger?
We don't need to do anything to prevent the destruction of our species because we are not in danger. So many people are convinced we are not in danger because they think rationally, and do not believe unbased scaremongering.
