alex Cui Posted about 2 years ago Is it possible for our planet to "crash" due to being a closed biological system? There certainly are limitations within Earth like soil energy, and fresh water. I feel like humans are bound to hit rough rocks before they do anything substantial as part of alleviating climate change/crash and helping sustainability. Many believe we have the technology to do so, just not the political/economic will (which is just as important). An alarming fact is that according to carbon footprint studies, we use more Earth than there is available as is, and that means, in my opinion, there should we a pressing concern that we have to be more sustainable. I have seen a few counter-arguments towards overpopulation control, about how population will in fact level or drop, and I consider that unlikely considering how poverty will continue and possibly worsen over the years, (with 40% of pregnancies being accidental) those in poverty (a good 1/3-1/2 of the world?) will not stop reproducing (without change, of course). With a loose, open perspective, I believe that there is a need of both develop countries to stop consuming more than feasible, and for poorer ones to stop producing at such an alarming rate. The only thing for me to find out is why these are happening, and what their solutions are also.
