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.
Or simply to act to with moral coherence and avoid unnecessary cognitive dissonance. So that’s one difference between our attitudes.
That would IMO be a negative impact. Ecoterrorism does not work. Wrong ethically, and counterprodutive. So that’s a second difference.
These are questions of deep philosophy, not simply judgements based on facts. You don’t see things as I see them, and vice versa. In a pluralistic society that should be manageable.
Hence this third difference. The very fact that we can express disagreements like this and not be arrested is proof of something. The fact that our politicians are useless or malevolent is because we are those things. No societies in human history have been as free and democratic as the modern West. Things were (much) worse before, and soon they’re going to get much worse again.
Anyway. An unbridgeable gulf. Others can decide which of us, if either, is “right”.
