Friday 阅读理解 D

For centuries, experts have described periods of human history by the technologies or materials that made the greatest influence on society. Examples include the Stone Age, Bronze Age and Iron Age. But what age are we in now? For some researchers, that question can be answered with one word: plastics.

There is no place on Earth that plastics are naturally made. The many kinds of synthetic polymers (合成聚合物) would not exist if it weren’t for human action. About six billion tons of plastics have been made and spread around the planet, from forests to oceans since the first plastic polymers were invented.

To make the problem more serious, most plastics don’t easily degrade (分解), and recycling isn’t a good method to deal with it. Besides, there are only a few recycling factories in the United States that can process all kinds of plastic.

Although millions of tons of plastic are recycled every year, millions more end up in the ocean. The problem has reached the point where it’s possible that in just a few years there might be more plastic in the world’s oceans than fish.

The plastic can exist on the planet for over 500 years, so it’s safe to say that every plastic bottle you have used exists somewhere on this planet, in some form or another.

Even if human populations worldwide change their plastic-using ways, the damage may already be done. With plastics existing everywhere around the world, the Plastic Age might soon take its place in the history of human civilization.
