How much meat can we eat – sustainably?

We cannot keep extracting more and more resources from our finite planet, at least not without destroying it in the process, as the current situation clearly shows.

The root cause of the issues pointed out in the article is the level of the global population. If we were, say, 500 million on the planet we would not even be discussing how much meat we could eat sustainably because we would not have that problem in the first place.

Dismissing this as "Malthusianism has been proven wrong" is dangerously misguided and myopic. Unfortunately many people refuse to face reality for ingrained cultural reasons, it's in effect taboo.

It doesn't have to be Malthusianism at all, that is a reductionist perspective. There is an earth overshoot day and some resources simply cannot be restored or extracted with increased productivity.

You could argue that there would be enough production capital to feed everyone. There certainly is and then some. But that is certainly not the whole story. Imagine our resource consumption if everyone lived to western standards.

I don't know how you can simultaneously argue that anthropological climate change exists but a large human population is irrelevant. Doesn't make sense it seems.
