塑料是大家日常不可或缺的一種原材料。大家用它制作像購物袋、瓶子或包裝等等的平時用品。但那些被大家遺棄的塑料制品最后總是會被倒入海洋中，而事實(shí)證明此做法給野生動植物的存活帶來很大的挑戰(zhàn)。

How many plastic carrier bags have you got in your house? I seem to have cupboards full of them and it feels like theyre taking over my home! The ubiquitous shopping bag is just one example of the million things we use made from this useful material, plastic. But unfortunately, its not the easiest thing to recycle and this is causing an environmental problem.

Most of our everyday plastic items end up in landfill, left to rot away for many years. But some of it blows away, blighting1 the countryside and causing damage to the natural environment and harming wildlife. The problem is most acute in our oceans. Research has found an uninhabited island in the South Pacific is littered with the highest density2 of plastic waste anywhere in the world. Henderson Island, part of the UKs Pitcairn Islands group, has an estimated 37.7 million pieces of debris3 on its beaches.

The study, published in the journal Proceedings4 of the National Academy of Sciences, described how remote islands act as a sink for the worlds rubbish. They become collecting points for fishing items and everyday things including toothbrushes, cigarette lighters5 and razors; things that we throw away. Dr Jennifer Lavers from the University of Tasmania says Almost every island in the world and almost every species in the ocean is now being shown to be impacted one way or another by our waste.

This highlights the potentially deadly effect of our disposable culture. When we throw something away, it doesnt just disappear, it goes somewhere and because of the durable6 nature of plastic, it takes a long time to decompose7 and stays there causing great damage to the oceans ecology. Some other recent worldwide research estimates that 90% of all seabirds have swallowed plastic. And worse still, this plastic is broken down into tiny particles over a long period by the wind and the waves, then sea creatures at the bottom of the food chain ingest them. These creatures are eaten by the fish that we eventually consume.

The solution to this problem would be to use less plastic. Several countries now charge for using plastic carrier bags which reduces the amount used and some products now use natural and recyclable materials but it seems inevitable8 that plastic will continue to be necessary in many of the gadgets9 that we demand.

So next time you pick up a carrier bag, or buy a plastic bottle of water, spare a thought for the birds and animals on the remote Henderson Island. What do you do to help the environment?
