The doom didn't stop being impending. As an individual all you can do is doing your part in recycling and saving energy, and gaining citizenship and/or permanent residency in a country that is able to produce enough food for its own population by multiples, and spans enough climate zones to be stable in any scenario (hotter, colder, more dry, or more wet).

Because as with the current vaccine shortage, there's no international cooperation when the countries producing it don't have enough. Food shortages will be similar.

Your choices are probably Brazil, USA, or Russia.

To be clear, recycling is greenwashing. The problem is consumption. It truly does not matter if we put waste in the correct bin if we do not also dramatically decrease our use of single-use and otherwise disposable goods.

Recycling is a marketing tactic crafted by the tin can industry in the 20th century to dethrone reusable glass bottles for products like beer.

That's true, we need to recycle ourselves by repairing things that are broken.

Isn't whether these claims are true the relevant argument to be making here? If they're true then steady warnings and coverage in the media are not something to complain about. If they're false, then any amount of media coverage is something to complain about.

It's not simply "steady warnings." It's the doomsayer nature of the news and the fact that they have a provable profit motive for making things as extreme as their viewers will accept.
