Reduce your carbon footprint in NOT part of Thunberg's message. Thunberg is all about imploring world leaders to listen to the climate scientists and blaming them, along with adults for the current mess we find ourselves in.
Thunberg says she doesn't fly, she doesn't suggest anybody else do the same.
Here's a way to look at things. The next time you turn the key in your car's ignition, don't think of that sound as an engine starting up, think of it as the sound of a teeny tiny volcano erupting. By turning that key you've effectively drilled a little hole miles into the Earth's crust and your letting out a little bit of carbon that's been safely sequestered away for millions of years. You might not be able to see that carbon dioxide coming out of your tailpipe, but Greta can and she's very. very angry about it.
When you step on the accelerator, thing of yourself accelerating climate change. It's just a little acceleration but it's acceleration nonetheless.
