ANY effective, long-term collective change REQUIRES that the large majority of people CHANGE THEIR CONSUMPTION HABBITS. While not great, the private plane stuff is exactly as pointless as the paper straws. Both are ways for everyone to point the finger at everyone else, and not have to change.

If the government implemented the "correct" laws tomorrow, but the populace doesn't want to change their habits, they will vote in people that give them back their old, bad things.

If a company implemented to "correct" processes, but the consumers don't want to pay the necessary price, they go bankrupt, and the company with the "incorrect, but cheap" processes wins.

ALL COLLECTIVE ACTION IS A COLLECTION OF INDIVIDUAL CHANGE. There is no alternative!
