How do we change such a corrupt and "stubborn" system? It needs to start with the law. First of all ecocide needs to be recognised as a crime against humanity. It currently barely even rates a statute in a handful of countries. Then, people need to be held accountable for directly damaging the planet through their actions and business ventures and prosecuted and incarcerated. In extreme cases capital punishment might be the best solution.
