This century we will be facing the three toughest challenges humanity has ever faced. Overpopulation, Water shortages, and Climate change. Now governments and businesses are already beginning to address the water problem partially thanks to all the attention California has been getting these past couple years. Overpopulation in the long run may solve itself as a few study's have shown a downtrend in pregnancy and birth by 2050 leading to a 2.71 reproduction rate which is considered an equilibrium rate at which our society will stay at the same population once it drops to match that equilibrium. But some study's also show a rise in population still in which case it will be a problem worth starting to address sometime around 2030-2040 but that's not the issue im trying to get a poll on. The third issue, Climate Change is the biggest threat to humanity today with it causing the melting of the west Antarctic ice which is land ice and would cause see levels to rise. The acidification of the ocean which will kill ecosystems and push many animals to extinction and push many more to the brink. The permafrost (frozen ground) throughout the world is starting to melt and contained in that permafrost is more CO2 which will be released into the atmosphere if it continues to melt. It's predicted to have 3x the amount of CO2 than what's in the atmosphere right now and at our current pace its predicted that 70% of all permafrost will melt by 2100 meaning it will add 2/3 of the carbon trapped inside the ground into the atmosphere. What were headed towards is another great extinction but not one like the dinosaurs, we're headed toward a fate we made ourselves and are taking the other creatures gifted this planet along with us. We were gifted this great planet to cultivate not to dominate. Please give me your opinions as well but also please no non-believers as there's obvious proof that climate change is happening and that humans are majority to blame. Edit: it's sad to see a lot of people don't see the importance and danger of climate change Edit: happy to see more people visit this post and give their answer to the poll but I'd also like to hear more opinions on the subject Edit: I know climate change is also a natural thing but not at current rates we need to slow it down
