Recycling is a scam, and I didn't suggest it. But if a person went out every day for 5 years and planted 10 trees or created a food forest in their neighborhood or invented a trash collecting device for a lake or ocean (as people have already done) or changed their lawn into a bee garden or grew their own food - yes that would make a huge impact on their local ecology. And if everyone did that, the world would actually change. Good people can do anything. They are the ones who change the world in massive ways.

If you want to break the system, stop paying taxes, shopping at corps or corp adjacent companies, and stop using fiat currencies like the dollar. Money is the foundation of any society, and corrupt money creates corrupt societies. The world monetary system is on the verge of collapse, and a rather large group of people globally are helping push it to its demise while building a parallel financial system. That group started with less than 10 people 13 years ago.

Your defeatist naysaying is honestly really boring. Pick another solution; I don't care, but becoming a nihilist isn't one of them.
