This is exactly the example which is not sitting right with objective look at nature. We make arbitrarily like and talk about Monarch butterflies because they are so pretty and don't affect our lives except providing esthetic experience. On other hand nobody cares about millions of other butterflies killed by pesticides to protect our food. Though actually the once that we kill might be more important to ecological balance of our planet than rare Monarch butterfly. The point is that we judge more by our sense of beauty than by being objectively and morally just.
The issue at hand is, why don't we treat all animals equally? How does it make people fair, and legislated laws for animal protection right, if we consider some animals more important than others? What is our justification for preferential treatment; big eyes, nice colours, cute face, soft fur?
In the past it was much easier to decide. We were the dominant species, on top of food chain, and by law of nature we could do whatever we wanted with other animals. Now we want to protect animals and their habitats, but we are very selective in this approach, mostly protecting the cute and the cuddly. I don't think it is right.
I really like my guy bacteria. It really agrees with me and my diet. Nothing to complain.
