"There is a common tendency among effective altruists to think of animal advocacy as having little value for improving the long-term future. Similarly, animal advocates often assume that longtermism has little relevance to their work. Yet this seems misguided: sufficient concern for nonhuman sentient beings is a key ingredient in how well the long-term future will go.
In this post, I will discuss whether animal advocacy – or, more generally, expanding the moral circle – should be a priority for longtermists, and outline implications of a longtermist perspective on animal advocacy. My starting point is a moral view that rejects speciesism and gives equal weight to the interests and well-being of future individuals."
