I mean, nuking? That ain’t exactly going to fix anything.

Like, the whole idea is bad, but dropping nukes is it’s own environmental disaster as bad or worse than global warming.

Even using conventional munitions is going to cause fires and literal megatons of debris to be released into the atmosphere and water. This ain’t going to fix anything.

It also assumes that population control is the fix in the first place, and it isn’t. The population levels would only shift the speed of change, not the fact of it. To stop or reverse the changes, you have to change the underlying cause of the change, which is pretty much down to industrial processes across multiple areas, including agriculture.

Yeah, you kill off enough people, industrial efforts might cease, but it’s more likely that the remaining people are going to have to rely on the most effective methods to stay alive and functional, rather than the methods that are environmentally best.
