All good points. To add on to your climate change example: there’s a big difference between that (you can at least affect change there) and, say, getting mad at the day’s weather or human nature (which exists totally outside your control). Epictetus said (I’m Paraphrasing) “I’m fond of a jug. When the jug breaks, I simply sweep it up. It’s in the jug’s nature to break.” You could try to protect your jug but once it breaks, you can’t go back in time, can’t change the reality of it being broken. So, yeah, a stoic isn’t going to sit and cast anger into the past about damage already done to the environment but also won’t give up and do absolutely nothing about a problem that isn’t in their sole, direct control.
