Hi all.
In all the discussions of sustainability, I never see anyone talking about population control.
China has done a brilliant job in lowering their population numbers for the next generation – since couples were limited to one child, many more chose to have a boy, so now males outnumber females.
Our planet can't sustain unlimited human population growth. At some point, several things will happen:
When any species population gets too crowded:
a. Opportunistic disease wipes out a large chunk
b. Fights over dwindling resources
c. Starvation
Whatever the outcome, nature has a way of resetting the population to sustainable levels. Technology will only get us so far.
Going to other planets could be possible, but I don't think that would ever happen before critical mass is reached.
The world could agree to one child per female. After the one child is born, the female is "fixed".
I know people would hollar about reproductive rights. I'm a female … I know to some people having a big family is important life experience. But, we're talking about survival of the human race, we're talking about creating a decent quality of life for people in the future.
In wealthier countries you could tax additional children (instead of giving tax breaks – encouraging more children). But what to do in poorer countries with little birth control and the desire to procreate a lot of children?
If we don't stem population growth, no matter what we do "green" – we eventually will run out of resources.
