Did you miss the tired and overworked comment? Feeling exhausted and burned out doesn’t inspire most people to spend a large amount of time and effort learning something new.

The problem is that they are protesting the lack of laws and regulation. So they can’t break laws to show they are unjust. They can take direct action against those that are most responsible for climate change, and people have been doing that. They are also frequently charged, penalized, fined, and imprisoned. They are bringing attention to a problem and hoping enough people notice.
