This "struggle" leads to the erosion of institutions, their discrediting, and will end with the fact that in 50 years anyone who mentions ecology will be looked at in much the same way as Jehovah's Witnesses are now looked at. We wear plastic, we walk on plastic, we build and decorate with plastic, we drive with plastic. Fighting plastic bags is like fighting matches because forests are cut down for them, they emit CO2 when they burn, and they can start a forest fire. The only reason people tolerate with this is because they are dumb morons on average. But even dumb morons can't be fooled forever - and when society realize the extent of the lies and uselessness they've been fed with, good luck telling them even one thing about ecology, even if it's critically important, because they still remain dumb morons, only with zero trust in the ecology. So yes, definitely a good strategy to put the future of humanity and the existence of our environment at stake for tiny short-term political gains.
