The only way to save ourselves and Earth is to shut down everything. Shut down all the factories, all the manufacturers, stop mining for petroleum, stop everything. Reducing your carbon footprint is a good start to trying to make an effort, but not everyone is privileged enough to care about these issues. Not everyone is privileged enough to be able to worry about pollution. There are people whose priority is putting food on their family's table and not having to worry about their lights getting shut off.
So people in 1st world countries can continue to preach about reducing carbon footprint, but there's still hundreds of millions of people who can't afford to care about that. I know that's unrealistic to say that we should just shut down everything that's causing greenhouse gas emissions, but that's really the only truly effective way. We need to go back to primitive technology, we need to reverse industrialism.
