Whether an interest is trivial or not depends on how much it matters to us, and what you call trivial matters a whole lot to a whole lot of people. Look at what a big deal most of us make about going out for a steak dinner.We get all dressed up and spend a fortune. To some people, it's more than just nontrivial--it's the highlight of their week. Besides, what does it matter even if we say that such interests are trivial? If humans matter more to us than nonhumans, why shouldn't even trivial human interests matter more to us than any animal interest?"
