I agree this article isn't as terrible as average. Going vegetarian and cycling to work once a week might make you feel good but it ain't gonna make a difference. It's a political problem. It needs a political solution. Agitate and vote for the most left-wing party you can (that has a realistic chance of winning/influencing an election). Campaign for them to institute a ban on fossil fuels. Protest. Climb smokestacks…
What's that got to do with the price of fish? The main left parties in my area still harp on about the coalmines. Then you have the Greens who are anti-nuclear, anti-Gm, anti-everything who seem to spend most of their time now involved in infighting over trans nonsense.
