My counterargument to these types of things is that if every single person took every single action to reduce their carbon footprint they possibly could, the global economy would simply collapse, and probably very quickly. Large scale, systemic change and likely a massive reduction in consumption is needed - I personally think it unlikely/impossible in today's geopolitical and domestic climate. Then, these types will just start calling you a "doomer." It's all so seemingly scripted I always feel like it's coming from somewhere because it is so insanely counterproductive and predictable.
