The problem with this line of reasoning is that the only people who care are the anxious western upper-middle classes. Anyone poorer can't afford to care.

Instead you have to change the economy so that the most environmentally friendly alternative is the cheapest, and so that environmentally disastrous activities are prohibitively expensive.
