Environmental campaigners have called on the government to learn from its own successes after official figures showed the use of single-use supermarket plastic bags had fallen 98% since retailers in England began charging for them in 2015.
Annual distribution of plastic carrier bags by seven leading grocery chains plummeted from 7.6bn in 2014 to 133m last year, the Department for Environment, Food and Rural Affairs (Defra) said on Monday.
We already have a way to solve this, just don't drive so much.
Metal tires and metal roads. Kind of slippery, so we might need to make some sort of ridges to guide our vehicle's direction. Stopping will still be hard, but if we just lock cars together and do it all at once it might be feasible.
