I have friends who think that 2012 will be the last year of earth...however, if they really believed that, they would be spending all of their money right now...or going heavily into debt right now. Their actions don't follow their thoughts.
I have no reason to think that 2012 will be the end of the earth. I don't care about Mayan calendars, but if you believe that we are at the end of time, would you please put your money into my bank account at the end of 2011. You won't need it.
PS I also do NOT believe that the earth is overpopulated. The resources are not being used properly, but that is the fault of politicians and corporations. I wish that more intelligent Americans would have children. America can certainly use more people...that is why the government keeps the southern border open. Think about that for a bit. We don't have enough people to fund the Baby Boomer retirement because Americans don't have children. Stop listening to television and public school teachers.
China may be a different story because they may be close to the end of some of their resources, but in my world, smart people are being told not to have kids...to save the planet...WTF?
You may be the person who has a child who will find a way to save the planet. You need to have children so that we will have smart people to make the world a better place.
