I’m having a bit of trouble with my WiFi, so I’m going to just jump in with my two cents now.
I was actually in a debate the other day with someone who advocated for abortion because it is green.
Now, I’m all in favor of greenness, sustainability, and I’m even pro-choice. But I found his suggestion that the reason abortions should be done is for the environment to be disgusting. Really what we need to do is get at the root causes of all these problems, such as reducing as much as possible unwanted pregnancies, switching over to renewable energy now, and making it more efficient now.
I don’t see overpopulation being a problem- when a population gets too big then people start dying off from disease, famine, thirst, etc.
Distribution of resources is the problem. Environmental degradation is the problem. I’ve seen some high numbers here, but lets put it at 10 billion as a low end estimate. So, we can now synthesize hydrocarbon fuel, so eventually oil running out won’t be a problem. However reducing the damage done by the time we get to that point will, and we’ll have to see that our renewable hydrocarbons take in as much as it puts out. Either way, in order to sustain a population of 5 billion let alone 10 billion, we will still need high technology to distribute the resources. So, it’s in our best interest to develop green energy anyway. By the time the sun runs out of energy to give us, Earth will be fried anyway. The planet becomes uninhabitable well before the sun goes red giant (gradual heating up of the sun will shift the habitable zone- Earth is screwed in about a billion years). Anyway I’m getting off topic.
But I don’t see overpopulation as a problem. Besides, we’re going to need some of them to colonize other planets.
