I think
@Eboue has a point.
It's all well and good people talking about what's best for the environment and what's going to happen in the future, but unless you have a good way of communicating this and what you are doing for the current communities built around these things then you are on to a loser. Further to that, if you've no plan other than "they just have to deal with it" what do you expect these people to do?
We are talking about lives of real people built around generations. If you don't think it's at least a little bit wrong to just brush that aside for the sake of what you see as progress, well, then you don't get why the likes of Trump and Brexit is allowed to happen.
It's not all racism and evil thoughts, a lot of people just don't understand how the world needs to move on. And ridicule and blanket statements just isn't that great a way of educating them. Imo.
