No, they don't care either way.
For me everyone needs to start with themselves. That's the reason I drive an EV (seeing
@Murder on Zidane's Floor is present in this thread: The past 2 years I've managed about +70% solar
) and the reason I decided not to have kids (well besides my health, might change in the future but getting unlikelier by the year). I don't take flights anymore unless absolutely needed. However I do still have work appointments, social meetings, and other activities. Occasionally I still need to get somewhere, there's no way around it.
As for you personally you could very well vote in a government that doesn't sell oil to the entire world
