The simple solution for global warming has been the carbon tax. But obviously it is a bad idea to do "shock" taxes. A shock tax in ICE vehicles wouldn't maximize the effectivity of stimulating long-term BEV demand, it would be a huge regressive tax on the huge number of people that don't rely on new cars, but used cars for everyday transport. It would inevitably simply lead to political backlash. But a long term phase-in over a decade, which also is difficult to sustain over successive administrations and controls of congress, would be ideal. Obviously American governance is too incompetent to achieve that. The carbon tax is for the current largest environmental threat: global warming. But the sixth mass extinction will probably be the next big environmental issue once GW mitigations come into play. And the key to that is a big land tax to change incentives. And the same issues arise: how to avoid shock pricing and instead phase in over an economically adaptable timeframe. It even has the same technological potential solutions but lack of supply: vertical farms and artificial meat have the potential to eliminate huge swathes of land that are currently used for 1) grazing and 2) crops that feed grazing animals. Vertical farming and artificial meat should be getting massive research subsidies right now. Every research university should have substantial grants pursuing these. Because the habitats that we can reclaim back to nature and hopefully avert a total collapse of the "species web" is very important. I feel we are constantly playing russian roulette with extinctions. Was this species so important that everything collapses? No. Well, how about this one? This one? I mean, insect populations are dropping. Insects. Very concerning.
