That's impossible. We'd have to reduce to about half of where we are now just for the fauna to stabilize. We've just taken too much too quickly. In the oceans for example there's population collapse of entire genera in different locations every single year and entire dexoygenated dead areas in the photic zone because of overfishing and damage caused by commercial fleets. According to the IUCN Red List there have been at least ten extinctions every year for the past thirty years. It doesn't help that there's a rivalry going on between which country can post the highest numbers for a mostly meaningless metric in GDP, causing deforestation for livestock, overfishing for export, monocultures spreading dozens of miles for crops that have a fifty percent chance of being burned to preserve prices, and so much mining entire mountain ranges disappear.

I mean the article states the tobacco photosyntesized twice as effectively, with RsRubisco, which is actually less efficient the GmRubisco. So food-wise it seems hypothetically achievable.

I agree we'd need massive conscious degrowth in every other part of the economy though.
