“One common strategy on which we should all be able to agree is to take steps to reduce the risk of human extinction when those steps are also highly effective in benefiting existing sentient beings. For example, eliminating or decreasing the consumption of animal products will benefit animals, reduce greenhouse gas emissions, and lessen the chances of a pandemic resulting from a virus evolving among the animals crowded into today’s factory farms, which are an ideal breeding ground for viruses. That therefore looks like a high-priority strategy.”
