And then others will rise to take their place. If the demand is there, someone will try to meet it. All long as the vast majority of people are not willing to make changes in their own life, then everything else is pointless, and it will all fail.
EDIT: Stealing another comment to add to this:
what would happen if everyone turned around and said ‘you know what, fuck companies that sell drinks in bottles i’m never going to be without my refillable bottle’ how long would coca-cola keep producing 100 billion plastic bottles a year? what would they do with them?
But if James Quincey said ‘fuck it, I’m not producing plastic bottles anymore they’re bad for the planet’ but 8 billion people said ‘oh ok, well we’re still going to regularly buy drinks in plastic bottles’ the numbers of plastic bottles being made would dip slightly but only while Ramon Laguarta rushed to spend the flood of money now coming in to scale up production at pepsi co.
