I'm not suggesting for one moment that we should hunt our fellow Earthlings. I'm not against farming, just animal farming. Aside from the ethical objections to enslaving and killing other animals, it is such an inefficient way to produce calories. People grow crops (soya, for example) to feed to animals and lose 90% of the calories in the process. If we were to stop breeding animals and feed the crops directly to humans, we could feed the entire population on a fraction of the land we currently use.
Yes, nature is horrific, but we don't need to add to that horror. We are not obligate carnivores. We can choose peace.
