True, what you can do is plant trees and stop cutting trees. Plant trees that suck more CO2.

Amazon rainforest is being cut enormously. About 90% of cut Amazon is solely for beef production and soy exports for USA beef production.

Of course, the enormous convenient life of average USA citizen might need more government control (24/7 AC, cars everywhere, heavy reliance on animal agriculture etc.) and that stuff costs but it is long-term investment. Of course, no one sees 100 years as long-term, 100 years is invisible. Huge amount of forest also cut for palm oil. The new plant oil that ends up everywhere (sunflower oil turned out more expensive in this millenia).

I've heard from many parents that they don't care if their lifestyle habits promote the business-as-usual culture.
