You just posted a video where the host and guest think that there will be literally no humans left on this planet. That is just wildly improbable. This is like the science-y version of the Rapture. It appeals to people into doom porn. Climate change is a huge problem, but the Earth itself will be fine. People will live but their quality of life will decrease. It is stupid to let it happen though, so best not to find out who is right.
