Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

255 grams per week. That's the short answer to how much meat you can eat without harming the planet. And that only applies to poultry and pork.

Beef cannot be eaten in meaningful quantities without exceeding planetary boundaries, according to an article published by a group of DTU researchers in the journal Nature Food. So says Caroline H. Gebara, postdoc at DTU Sustain and lead author of the study."

Our calculations show that even moderate amounts of red meat in one's diet are incompatible with what the planet can regenerate of resources based on the environmental factors we looked at in the study. However, there are many other diets—including ones with meat—that are both healthy and sustainable," she says.

A quick search (meaning I did not dig into it because it's very hard to read tables on mobile) shows that France has about one third the rate of veganism compared to the global population, and a quarter of the US rate. (I chose the US because they're the poster child for obesity.) While they may be healthy, they're still eating meat.

While they may be healthy, they’re still eating meat.

Yes. How could it be otherwise?

I don't really understand how you can think meat consumption is necessary for health and also be against lab-grown meat. Is there some other way you have in mind to address environmental and ethical concerns? It doesn't really help to survive today if doing so means extinction later from climate change.

This isn't a binary thing (eat only meat, eat no meat at all).

Eat less meat of good quality is the way. How is that something you don't understand is beyond me.

meat consumption is necessary for health

There are statistical studies after studies that show that pure vegetarian diet require very careful planing long term, and there are no studies of long term strictly vegan diet. Humans evolved eating lean meat, how suddenly removing all of meat based produce from our diet could be healthy long term?

Look at the current obesity pandemics that steams from us messing up with what we eat, ultra processed foods etc. I can't even imagine what would lab grown meat do to us, as it would be even worse slob.
