Sorry but this article is pure PR. Nature is a cycle, animals do not "consume" food or "produce" meat. They live. A cow eating grass feeds the grass with its excrement and stimulate it's growth. The "issue" is for business who have to harvest food for their livestock to produce enough to sell enough at a price sufficient to earn their life.

Calculating "carbon footprint" is just calculating astrology, a narrative to scam their customers. Canada's wildfires last years polluted more than all antropic emission combined https://www.theguardian.com/world/article/2024/jun/27/canada... similarly Darvaza gas crater pollute much more than all flatulence and methane leaks from animals and humans together.

The point is that to feed enough human we need enough land for enough livestock and actually the current food production systems can't adapt to the climate change, huge number of humans AND BUSINESS so they try other ways to remain in business instead of evolving.
