As pretty as the idea may seem, it is far from satisfying for the animal world as for the plant world. If the robin still sings, it is good to crush the competition. If earthly ivy has chosen to crawl, it is good to monopolize space and prevent other plants from settling. When the hawk throws itself on a prey, it is not just to «participate». In nature, competition is more than a hobby: it is an art of living that can lead to… death!
