I've lost count as to how many times I've been called a leftist here on IMGFlip.
Sure, the problems are overexaggerated, but OP talks about them as if they're not problems at all.
Overpopulation, for example, inevitably leads to massive environmental destruction. Once the population of any species in a habitat increases, basic needs (food, shelther etc) in that habitat also increases. From that point, two things may happen:
1. The population uses up all resources in a habitat, and migrates to another habitat for resources where a simular destiny is likely to happen.
2. In case of human beings, the population starts building large cities, factories, shops etc to satisfy the large number of people. That, in and of itself, is massive environmental destruction.
Deforestation can cause many things, mainly floods and soil erosion.
Not an expert on acid rain and the ozone holes, so I can't speak on those.
Global warming, I'm not sure what to think about. It is definitely used as a tax excuse like many so-called conspiracy theorists say it is. I think it's real, but that it doesn't cause or will not cause the problems it's widely believed that it will cause. For example, melted icebergs will not lead towards massive floods. It will lead to endangerment, if not extinction of any and all species living on the icy habitats, as well as any species whose main sources of food are in those areas (killer whales, for example, because their main foods are penguins and seals).
12 years thing is laughable. Climate changes once in a while, no shit. It's not the end of the world, you AOC-loving dunce.
And nobody on the left, right or center can fix any of these problems (as if they're trying). Nutshell: https://m.youtube.com/watch?v=_jUY3DKq-Do
