(Yahoo News) - The United Nations has predicted a global population of seven billion this year, and a rise to nine billion by 2050, "with almost all of the growth occurring in poor countries, particularly Africa and South Asia," said John Bongaarts of the non-profit Population Council. - Planet could be unrecognizeable" by 2050, experts say
The first billion people mark was reached by 1850. By 1950, we hit approximately 2.5 billion. The figure passed six billion in the late 1990's. Keep in mind that it took humans 150,000 years to get to the first billion. The most recent billion mark was achieved in just 12 years.
So lets get technical and put some myths to rest. Joel Cohen, a Rockefeller University population biologist, argues that you could fit one billion people each a metre apart, into a field 32km square. Basically, everyone in the world could easily fit into Yorkshire.
Cohen is forgetting a few small details.
It would take approximately 900 metric tons (216,000 gallons) of water to support that many people. Lets do some math.
It takes 900 tons of water to grow 900 tons of wheat, or 1,800,000 pounds.
One Cubic Foot = 7.4805 Gallons
A pool that measures 30 Ft. Length x 15 Ft. Width x 5 Ft. Deep = 2,250 Cubic feet (2,250 x 7.4805) = 16,831.125 Gallons
That means we would need about 13 pools to support that amount of wheat. Seem realistic? According to average calculation, it takes 2.1 hectares of land and water to support the average human. The American average is 10 hectares. Yikes, talk about a required change in lifestyle! If the entire world adopted U.S. living standards, we would need four Earths to survive.
Life only exists through equilibrium, or balance. The corresponding rate of births to deaths are staggering. So, how many people CAN the Earth support? Currently, there is no one answer. But we do know, that without oil, and mass production, the Earth can only naturally support about a billion or so people. If the Earth ran out of oil, there simply is not enough food in all areas for people to survive. Without the ability to produce, or transport the mass produced food to so many remote locations, about a billion people will die of starvation in a matter of months to a year.
The short answer, is the Earth's population is growing at an alarming rate, and overpopulation will be an issue if something isn't done about it.
Having children is a responsibility, and a privilege. What if people had to prove themselves of the capability to be responsible, before having the privilege of having children? It's a little unnerving to see so many people in poverty that have 3, 4, and 5 children. At that point, I'd say strip their ability to have children. I'm not one to propose policy, but I do forecast the ability to have children will be a privilege, rather than a right at some point; Maybe not in this lifetime though.
I know special interests groups would go nuts if they read this, but the facts are the facts; the Earth can only support X number of people. It will be a matter of time before we start feeling the effects of overpopulation, and then we will know what that number truly is.
