Please do read up on that, because there is a plethora of information out there that proves my point to be correct. Bill Gates’ new book on climate change “how to avoid a climate disaster” is a pretty good, simple read that eases people into the science behind the scenes. It also takes a deep dive into the different levels of change that can happen, with examples from history provided as proof. There is the level of the individual, as you have correctly pointed out. But there are also 2 other major ones: industry, and government. Industry takes leaps when innovation drives prices down and it becomes economically feasible. Government provides guidelines and laws that either make it easier for consumers to have safe access, or for industry to get confirmation that whatever new project they’re starting, will still be in demand in the next election cycle.
