What baffles me since I first studied ecology in 1990-s and to this day is this inexplicable divide in certain someones' minds between "us" and "earth". There is no such thing. We are the one, the unity. There is no border, no difference between "ecosystems" and "us". The whole biosphere is a single, very complex, but undivisable system. Get rid of any tiny single part, like a single human being and it responds. In this light, I see the notions like childfree or extinction rebellion as cancer. People doing this do not even attempt to understand the real consequences of their actions.
