Due to the heatwave in the EU I've been experiencing a lot of climate change denial as well as a phenomenon that I can't quite describe. It's this pervassive idea that using a glass/paper straw or driving an electric vehicle somehow absolves you from doing more to care about the environment, but I honestly can't fault people since it feels like that is all someone can do.

As an individual, what can I do to combat climate change or is the issue so systemic that I am powerless?
