There is inherent value to a large species count. Exaggerate the situation and say the only animals left in the world were dogs, cats and cows. Extrapolate that same sense of massive loss to this situation. If you don’t care then I guess there isn’t anything else to say to you but recognize that the loss of species diversity causes many people to feel an immense sense of loss, comparable to say large scale genocide of a human ethnic population.
