Dr. Richard Oppenlander suggests that ethics of meat consumption is not just about animal rights, but also the following:
1. Is it ethical for any one of us to eat food that causes the extinction of other species if we don't need to?
2. Is it ethical for the vast majority of humans on Earth to cause or contribute heavily to irreversible climate change, loss of our ecosystem and resource depletion while 2% of us are living our lives to protect Earth?
3. Is it ethical for any of us to use our planet in a way that exacerbates world hunger and extracts the potential for future generations to survive?
4. Is it ethical for 310m Americans to essentially impose their diet-related healthcare costs on the 5m that choose to eat the right food?
