I decided that I should wait to have children until I could support them on renewable energy, etc. which never happened. There is definitely no lack of children - I'm more concerned with keeping others safe than presuming to take responsibility for more.
If we were to do a time-lapse of the Earth circa 8k B.C. (dawn of civilization) to now at about a frame per year (10,000/30 fps = 333 seconds = 5.5 minutes) humanity would look like a giant festering algal bloom. As a student of biology, I don't need to tell you what happens to that algal bloom when it's depleted it's nutrient source, but for all those that aren't aware: all the algae dies. The problem going forward with humanity isn't one of enough fresh new bodies to refresh the ranks, it's about keeping the production of those new bodies small enough to be sustainable. Harder said than done when our entire systems are built around 'more, more, more', but I don't doubt some sentient species will figure it out in the future. Forget renewable energy for second, you're already doing the right thing by not adding a mouth to feed to a species whose own over consumption will eventually lead them to go 'pop' just like the algal bloom.
