I always thought my children, if I'd have them, might die a horrible death due to climate change.
Now, knowing that humanity with climate change in mind, only increased spewing CO2 in to the atmosphere, I think I actually eillmdie a horrible death due to climate change.
The no children thing for the climate is multiple generations too late already.
Also, keep the idiocracy effect in mind. Only the good and caring people decide not to have children, the idiots and selfish assholes will have ten for them.
