I think it’s just part of how languages work and people communicate, at least for people learning a second language - but I even do it in my native tongue, so I think it’s general.
For example, if when you are learning English you hear a lot of people say “God dammit” when they are frustrated, then when you are frustrated you’ll probably also start saying the same without ever even thinking about God. It’s essentially just a series of sounds when you learned to make to express frustration.
It does bring up the topic of climate change several times, and yet’s still more than the protest that do happen, but you never hear about because they don’t inconvenience anyone. There have been plenty of instances of protests vandalizing rich people’s yachts, for example, but that doesn’t make the headlines and people don’t care, so no attention is raised and it’s ultimately meaningless.
