We can adapt to climate change as a species better if each of us personally take the steps to mitigate its impact and learn to live with far less consumption than we currently do.
For example, making consumption changes and politically boycotting major corporations has been life-changing for me. I'm far less stressed about money because now that my tiny home is clutter free, I go out of my way to avoid buying stuff I don't really have a need for.
Every little effort in the right direction counts. It doesn't have to be everyone and everything.
