Those activists you seem so annoyed with are trying to promote the survival of the entire ecosystem by making sure that indicator species survive. All our food for 7 billion+ people comes from the soil and the sea. The productivity of both are supported by a complex web of life. Each species that goes extinct snips at a thread of that web. If one of those webs were to collapse, most of us would starve. Mars is a dead world. We have just this one living world. Money is just a social construct, you can't eat it.
