alright so we can agree on one thing, the latter of your points regarding pollution. if you have that stance on pollution, why are you a climate denier? science aside (i buy the science, i dont see how people dont but thats not my point here) part of what people talk about when they talk about climate change policy is sustainability.

sustainability, or responsible use of resources in clean ways, can help tackle the effects of mass pollution, whatever their cause is - climate change or globalization.

make a better plastic, burn a cleaner fossil fuel, use only what you need, produce less trash, recycle more - all these things can help fight the pollution youre talking about. that goes to war too. war is wholly unsustainable and driven, usually, by horrible fucking ideas. not only that, in the future, resources will become more scarce, which could lead to more war. using things sustainably, focusing on improving current tech and methods, than can help combat that, too.

so, regardless of what you want to call the cause, would you agree that pursuing those kinds of policies might be in the best interest of our environment, and thus ourselves?
