The other side knows this, which is why it ridicules our movements at all times. When, for instance, 400,000 people march on New York City, I know that I will get a stream of ugly tweets and emails about how—saints preserve us—it takes gasoline to get to New York City. Indeed it does. If you live in a society that has dismantled its train system, then lots of people will need to drive and take the bus, and it will be the most useful gallons they burn in the course of the year. Because that’s what pushes systems to change.

When brave people go to jail, cynics email me to ask how much gas the paddywagon requires. When brave people head out in kayaks to block the biggest drilling rigs on earth, I always know I’ll be reading dozens of tweets from clever and deadened souls asking “don’t you know the plastic for those kayaks require oil?” Yes, we know—and we’ve decided it’s well worth it. We’re not trying to be saints; we’re trying to be effective.

... Movements take care of their own: They provide bail money and they push each other’s ideas around the web. They join forces across issues: BlackLivesMatter endorsing fossil fuel divestment, climate justice activists fighting deportations. They recognize that together we might just have enough strength to get it done. So when people ask me what can I do, I know say the same thing every time: “The most important thing an individual can do is not be an individual. Join together—that’s why we have movements like 350.org or Green for All, like BlackLivesMatter or Occupy. If there’s not a fight where you live, find people to support, from Standing Rock to the Pacific islands. Job one is to organize and jobs two and three.”

And if you have some time left over after that, then by all means make sure your lightbulbs are all LEDs and your kale comes from close to home.

--Bill McKibben: The Question I Get Asked the Most

I've personally witnessed the tension between people who equate individual environmental impact with morality and those who are trying to organize social movements. I wish they were complementary, but often that is not the case. The condescension from people who can afford environmentally-conscious products or have hours to spare for less time-efficient forms of travel and cooking is destructive to movements, especially when organizing in low-income and immigrant communities. Ecological individualism is great if it is done in ways that complement or support mass action, otherwise it is merely performative.

Unless you're a millionaire, I don't care how you're spending your money, as long as you're there when we need you.
