Many countries have banned single-use plastic bags. It’s a good start, but all plastic bags in shops should be banned.
The ban is well supported but there have been cases of plastic-bag rage at shops when people have forgotten them. This is an example of declining standards; no shop assistant should be yelled at for a customer’s mistake.
There are already too many bags in our rubbish tips and ocean creatures’ stomachs. Grow up, get cloth bags and reuse them.
