Nonsense. The problem isn't excess population, but stupid government policies (both here and abroad).
The world consumption of oil, for example, would be a lot less if there were fewer people consuming it.
Unlikely. If the world population were smaller, there would simply be a smaller market (less demand, less pressure for exploration, etc.).
A lot of the illegal immigration problem in the US was brought on by Mexico’s population problems.
This is more baseless conjecture. The illegal immigration problem in the US was brought about by bad policies from the time of FDR via the Bracero program. The pressures on the Mexican side that allowed the problem to continue were due to incompetence and corruption of their federal government. It continued on our side due to a federal government that refused to do its job to protect our borders because it thought we needed the extra labor to sustain economic growth.
I think the Muslim world in particular needs birth control.
What the Muslim world needs is to change religions.
We can’t ignore this problem, unfortunately.
The "problem" is people like you. Your kind caused most of the misery in the 20th century.
Birth control is “misery?” You’re delusional. There is going to be a whole lot more misery than that, if we continue to grow the world population at the rate that it’s been growing.
