We usually discriminate between humans and non-humans, thinking that we are more important than other species. We humans are made entirely of non-human elements, such as plants, minerals, earth, clouds, and sunshine. When we see that humans have no self, we see that to take care of the environment (the non-human elements) is to take care of humanity. For our practice to be deep and true, we must include the ecosystem. If the environment is destroyed, humans will be destroyed, too. The best way to take good care of human beings so that they can be truly healthy and happy is to take care of the environment. Protecting human life is not possible without also protecting the lives of animals, plants, and minerals—the rocks, the soil, the rivers, and the oceans.
