I actually think we broadly agree - my point is that the answer isn’t to just recycle harder at the individual level, or even to get members of your community to do the same (though it’s certainly a good thing to do) - the real change comes from the push for systemic change that’ll affect both the populace broadly, and corporations. Yes - the most effective way to do that is to build a community of people that are all pushing in the same direction - lobbying for policy/party changes in government, pushing companies to be better, etc.
Again, my views are a product of looking where the biggest contributions to the problem come from, and the changes where we can move the needle the most. A bunch of individuals changing is good, a bunch of individuals changing the government to change the whole state/country/corporate regulations is far better.
