This does seem to be the result of human activity. But I'm not really sure how the words 'we' and 'choose' work in a sentence like that. The collective of humanity doesn't really make choices the way I understand that word. And, while individual citizens make choices that contribute to this, and business people and politicians make choices that prioritize the short-term over the long term, it's not really correct to say they prefer and therefor choose the climate change. It seems like we don't have a good vocabulary for talking about the cumulative results of small choices.
I get what you’re saying, but that doesn’t seem helpful. We don’t need to discuss better words to describe the intricacies of the situation, we need to do something about it.
It also doesn’t help to keep saying “this does seem to be the result of human activity”. “Seems to be”? It is, the science has been clear on that for a long time. But even if it wasn’t our fault, it would still be our responsibility to fix it. Because, you know, we live on the planet.
If I’m inside a house and it catches on fire, I’m not going to kick back on the sofa and not do anything because I didn’t start the fire. If it started because a group of idiots decided to launch fireworks inside, I’m not going to argue semantics about who exactly thought it was a good idea and who didn’t—the fucking house is on fire—what we need is for everyone to work together right now to put it out.
