And Thucy, someone already wrote it earlier, but I don't think you cared to answer to that:
Imagine this, you do your thing, tell people not to vote, how this will change the system for the better and you'll finally be able to take care of the environment. So you make a huge action (well, this would require a huge action to have any effect, but again, by your logic the effort is already futile because you don't have millions of dollars) and guess what. You succeed! Every single person in the USA that gives even the tiniest fuck about the environment stops voting. Every single one of them. There are a whole bunch of programs about you, interviews, how the fuck did you pull that off without those millions (Btw, I wonder how much would turnout drop, like 10%?) Bottom line - politicians, both in government now and the candidates, they know that not a single voter in US cares about the environment so they can stop caring too. Hell, caring about environment is quite costly, and rather unpopular with the guys who vote. So they think, why make any proenvironmental agenda if it would only have negative effect on our (re)elections? And getting to rule is fun, no matter how noble and good a politician would be, he'd always want to get (re)elected. And what if the (re)elected without the votes of all the people who didn't vote, with all those proenvironmental voices left unheard? Nothing. It's legal. They knowingly disenfranchised themselves. So dude, if you succeed in convincing people not to vote - the environment is on you,
