A few years ago I wrote a book taking this idea and running with it. In How to Spend a Trillion Dollars I end up using most of the money on transitioning to a net zero society, and in restoring nature globally. With a billion dollars, I would set up a progressive thinktank funding climate-positive and nature-positive lobbyists to counter the malign, fossil-fuel funded influence of Tufton Street and the Heritage Foundation.
