That is literally part of the deal of not living in a literal dictatorship. It is your responsibility to solve societal problems. I mean, geeze what did they teach in civic classes in your generation?
So if you believe that it is your individual responsibility to solve societal problems, and assuming you believe in the possibility of human-driven mitigation of climate change: presumably you individually are solving that, by devoting your life to it? Or do you not really mean it's your individual responsibility?
