- Antibiotic-resistant bacteria evolution
- Animal cruelty
- Pandemic virus evolution
- Climate change
- Air, water, and soil pollution
You couldn't be more wrong. The overwhelming majority of people are against animal cruelty and creating more antibiotic resistance through cattle farming, even if it means slightly-to-modestly more expensive meat. The reason it continues is a failure to inform (seen the insides of many factory farms on the news lately?), organize, and act to that end. It is not because of selfishness that it continues (except the selfishness of those profiting from it, but there will always be someone selfish, no matter how selfless the average person gets), but because the virtuous have not gathered enough power to stop it (at home and especially abroad [1]).
Self-flagellation will accomplish nothing.
