We'll get a chance again in four years! Little by little, decade by decade we can move the whole thing left. In the meantime I suggest investing in green technology. We recently bought a third Tesla. As a retired engineer I moved my 401k into a Thor Inc, it's a ammunition producer that uses recycled aluminum for all their missiles. Other things you can do is getting involved in your community! Using my engineering skills (did I say I was a retired engineer) me and my 40 year old son build micro houses for the homeless/cats to live in. It's all made from recycled materials. Corrugated plastic from old election yard sign as the main structure. For insulation we use unwashed (saves on water) styrofoam fish boxes from our boat club.

You gotta give back a little, that's what I say.
