I have a plan! Let's go colonise these resource rich countries. The inhabitants can barely provide for themselves, so it makes further economic sense to maybe
give them visas and citizenships. Golly look at our
developed economy!! Fast forward and we run out of money: Please go back to your rock and let's forget we ever met. We engaged with those people either for charitable or ulterior motives, it is a moral duty to at least provide them a chance to basic healthcare: soap and vaccination go a long way.
Is population control by means of prevention (education, condoms, more condoms I say !) a sensible idea? YES. There will always be issues with selecting an arbitrary number for fertility rates, but a seven fold increase will soon prove unsustainable.
Now, it's beyond the scope of my comment to prove you wrong; however any pollution metric you will pick
- waste contaminating water/soil
- oil spills
- air pollution - coal/car exhaust/ petrochem plants
- plastic landfill
- idiotic fishing policies
will tend to consistently peak in any other place than Africa, with top offenders being (in no order): America, Europe and China.
The harsh truth is that each and every one of us sitting with a laptop in our lap will have contributed in our lifetime to making the environment a bit worse than it was before us. It adds up.
