> We should also start taxing carbon emissions.
Yes, but not without developping the alternatives. For example, in France, the government decided to raise the taxes on gas and especially diesel — but at the same time, the small train lines are being shut down, so people living in the country aren't to happy.
People in the country usually pay a lot less rent/housing. Paying more for transportation is to be expected if you don't live in a city.
If they don't like it, they could try to move to a city and swap their high transportation cost for higher rent.
It doesn't take that many people to shift a society to a different behavior.. We used to slave and human-zoos not that long ago and everybody was like, that won't change soon.
Have you thought about going vegetarian yourself?
Personally I think we should be building more nuclear power plants as well as deploying giant battery storage facilities to store energy from wind and solar.
We should also start taxing carbon emissions. So advocating political change to achieve collective action seems like the only feasible way to do anything effective to me.
