I’ve read in an Article that meat production causes a lot of co² emission. Now I was wondering if we stopped eating meat completely, would that be sufficient to get under the threshhold of emissions what the planet can process? What is that threshold? Where are we now? How much does meat add to this?
Animal agriculture only produces 5.8% of greenhouse gasses[0], so even if everyone stopped eating meat tomorrow the effect would be less than 5.8% (not all animal agriculture is for meat).

That doesn’t Account for the deforestation caused by ever expanding beef pastures. It’s also unclear whether that slice includes the farming of soy, corn and alfafa grown exclusively to feed animals. And then there’s the “energy in agriculture and fishing” section that you probably missed. And let’s not forget how far meat has to travel, that’s in another slice in the energy section.
So probably there’s a couple percent more on top of that.
You forgot ocean acidification from farm runoff and the overfishing destroying the oceans ecosystem.
