     Ask someone what they have done to help the environment recently and they will almost certainly

mention recycling. Recycling in the home is very important of course. However, being forced to recycle

often means we already have more material than we need. We are dealing with the results of that

over-consumption in the greenest way possible, but it would be far better if we did not need to bring so

much material home in the first place.

    The total amount of packaging has increased by 12% between 1999 and 2005. It now makes up a

third of a typical household's waste in the UK. In many supermarkets nowadays food items are packaged

twice with plastic and cardboard.

    Too much packaging is doing serious damage to the environment. The UK, for example, is running out

of it for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go

on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not

to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets

encourage customers to buy more than they need. However, few of them are coming round to the idea

that this cannot continue, encouraging customers to reuse their plastic bags, for example. 

     But this is not just about supermarkets. It is about all of us. We have learned to associate packaging

with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it is also applied to a wide range of consumer products, which often have far more packaging than necessary.

     There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.
