Yes, there are some underlying issues which seem rooted in conservatisvism or rather its expression in modern politics.
But activism is not only about informing, it’s about pressuring the ruling class. And the more people support it, the better it works.
The ruling class was against civil rights, women’s rights, freeing slaves, Mahatma Ghandi, and so on. They were not convinced by facts, reason, or science. The people who are convinced by these need to show politicians that they are willing to stand up and protest if they don’t listen.
The corporations and the nations allowing them to do so are not acting lawful. They are violating the Paris agreement. In many (almost all) countries, the protection of the environment is also a constitutional right. That’s violated. The European court of Human rights has also ruled that climate action is a human right.
International law, constitution, and human rights are some of the most important laws that we, as a civilization and society, have.
