A major, world wide effort is urgently needed.
That's for sure, but it will take a long time, and will be fraught with all kinds of problems. That our love affair with plastic packaging has reached ludicrous heights is evidenced by Sainsburys offering shrink-wrapped coconuts for sale.
large amounts of fruit and vegetables are sold without packaging, but soft and easily bruised fruits couldn't be sold that way. There is already a big problem with apples in supermarkets because under the food standards rules an apple cannot be offered for sale as class A if it has a single bruise. People pick over the apples to find 'perfect' examples, and in doing so they bruise lots of them.
What's really needed is urgent research into biodegradable alternatives for packaging materials.
