　　In 2003, I was told by a restaurant owner on a Thai island that local fishermen used to wrap their lunch in banana leaves, which they would then casually toss overboard when done.That was OK, because the leaves decayed and the fish ate them all.But in the past decade, he said, plastic wrap had rapidly replaced banana leaves, so the beach was edged with a crust of plastic.

　　This is a worldwide problem—we can’t point the finger at Thai fishermen.The UK alone produces more than 170m tons of waste every year, much of it food packaging.Now we live in an absurd age where a packet of cookies can have seven layers of wrapping.While it has revolutionized the way we store and consume food, there is now so much of it that landfills(垃圾填埋场) can’t cope.Some of it is poisonous, and some of it never degrades.It can take 450 years for some types of plastic bottle to break down.Indeed, as Rachelle Strauss of the UK’s Zero Waste Week says, we never actually throw anything “away”—it’s really just put somewhere else.

　　It’s easy to say despair at the scale of handing the plastic wrap, but it isn’t beyond humanity to solve it—look at how the world took action on CFCs(含氯氟烃): there are signs that the hole in the ozone layer is now closing.Food packaging ought to be a doddle.

　　Comment 1:

　　While as an individual I can do my best to avoid excessive packaging, it is really only government regulation that can force corporation to change their practices.

　　Comment 2:

　　I never understand why supermarket chains insist on covering products such as bananas and cucumbers in plastic wrap.Why? They have their own packaging—the skin or peel!

　　Comment 3:

　　I love packaging—if it’s well-designed of course.It helps us be more hygienic and practical.The solution to these packaging necessities is clearly to encourage the use of bio-degradable packaging.

　　Comment 4:

　　Before, everything we threw out was bio-degradable and now it’s not.Guess it’s hard to change that behavior overnight.
