The protection of obscure species concerns a small portion of activists very much, and they are very loud in their activism, but there are other large portions of the population that don't care nearly as much and would prioritize economic growth over protecting endangered species. The activists' personal convictions are not more important or more valuable than those of people who don't care as much for endangered species. They're just different, and the activists tend to be louder and more passionate in voicing them.
