We account for every harm caused and No that is misinformation that has been debunked many times. It's not even a logical statement. All our choices are based on causing the least harm. Trillions of animals are killed every year for food and we do not even need to eat animals. It's not sustainable.

Eating a single grazing animal (goat) is less harm with less input than a fully plant based diet. Without habitat loss. Studies have been done. It's a balance.
