For centuries, historians and archaeologists have defined periods of human history by the technologies or materials that made the greatest impact on society — like the Stone Age, Bronze Age, or Iron Age. But what age are we in now? For some researchers, according to Atlas Obscura’s Cara Giamo, that question can be answered with one word: plastics.
“Plastic has redefined our material culture and the artifacts we leave behind. It will be found in stratified (分层) layers in our trash deposits (沉积层)” That’s according to archaeologist John Marston.
The wide variety of synthetic polymers (合成聚合物) would not exist if it weren’t for human action. Since the first plastic polymers were invented, about six billion tons of plastics have been made and spread around the planet, from forests to oceans ever since the first plastics polymers were invented.
Plastics are one of the most significant changes that humans have made to the Earth’s makeup. Most plastics don’t easily degrade. This only adds to the problem. Recycling isn’t an adequate solution. Not all types of plastic are easily recyclable. And there are only a few recycling plants that can process all varieties of plastic.
According to Debra Winter, writer for The Atlantic, this means that many of the materials thrown into recycling bins can cross the planet several times before they are processed. They are made into produce rugs, sweaters, or other bottles. Although millions of tons of plastic are recycled every year, millions more end up in landfills or the ocean. The problem has reached the point where it’s possible that in just a few decades there might be more plastic in the world’s oceans than fishes.
“Plastics have a supposed life span of over 500 years, it’s safe to say that every plastic bottle you have used exists somewhere on this planet, in some form or another,” Winter writes.
The damage may already be done. It may be too late for human populations worldwide to change their plastic-using ways. So the Plastic Age might soon take its place next to the Bronze Age and the Iron Age in the history of human civilization.
