The UK dropped to 500 million bags annually used from 7 billion after introduction of a 5 pence per bag charge. That's just one country albeit one of the world's largest. Still I think we're over due for much more agressive action. https://www.theguardian.com/environment/2016/jul/30/england-...
> The UK dropped to 500 million bags annually used from 7 billion after introduction of a 5 pence per bag charge. Still totally insignificant.

If you instead care about "items" or "visual cleanness of the river that all the plastic gets blown into", it's a very different matter.
