I agree with your sentiment and would advise the same. However, I would caution anyone sympathetic to the idea: we are probably at the stage where the current generation(s) who can make a difference have to plant trees whose fruit they will not taste.

The problem exacerbated from decades and decades of causes piling up into today's effects. You are not going to undo all of that magically even with sweeping legislation or communal will. The future of a good world is still there but maybe not for us to savor.
