I'm not arguing a position for or against action, I'm pointing out that things are worse than the quote claims, and I'm pointing it out because there is a long history of downplaying the severity of the situation when it comes to this issue.
Whether it's pointless or not is up for debate. Your brake pressing analogy could be slightly off. Rather than being in the moment before the car accident, we could be in the moment just after driving off of a cliff. In that case, brake pressing is indeed futile. But I think the system we're in is too complex to know for sure, and I'm all for people wanting to say that they are interested in doing anything they can. I'm also all for people actually taking action rather than just saying they are on board with the idea. Also...just do nothing if that's your preference.
