No, we cannot be the solution. Individual consumer behavior cannot change systemic issues. The only viable solution to Climate Change is at the ballot box. Out of control billionaires and vested fossil fuel interests cannot be swayed by asking people to pretty please go into massive debt to buy a Tesla instead of a sub 10k beater they can afford.
Nothing of what you're suggesting is sufficient or even realistic for most people. You want someone earning 30k a year to buy solar panels!? Are you mad?
We don't need a handful of people doing zero waste perfectly, we need millions to EAT THE RICH.
