At least in theory, our governments are voted in place exactly by us. Trump voters loved his ideas and he's implementing them now, yay success. Also industrial pollution is fueled by our buying habits just as well - if nobody would order stuff brought by ship from overseas, well, we wouldn't have many of those huge(ly) polluting ships around. So I wouldn't leave out the personal responsibility here: we make decisions every day, and giving up paper straws is only the most insignificant one.
