I know this is trotted out a ton, but those corps make those emissions by selling their product to consumers. We have a personal responsibility in this. We support those companies with our money.

You're kinda right, but at the same time we need to stop purchasing stuff that they sell that create population.

One example I can think of are those god damn coffee pods. Or disposable razors. I buy my coffee from a bulk store with my own reusable containers, grind it and use a French press to make my coffee. My razor is an old fashioned metal safety razor and I buy the individual blades alone. No plastics. This is so much better to fight pollution.
