Are we living in the Plastic Age?

For centuries, historians and archaeologists have defined periods of human history by the technologies or materials that made the greatest impact on society. Examples include the Stone Age, Bronze Age and Iron Age. But what age are we in now? According to Atlas Obscura’s Cara Giamo, for some researchers, that question can be answered with one word: plastics. 

The idea of named ages is not to be confused with geologic subdivisions of time like the Holocene. Nor should it be confused with the proposed Anthropocene - the proposed age is a period resulting from massive human impact on the planet. This most recent geologic epoch is not yet official, but there have been many calls for its designation. A recent study argued that the Anthropocene began during the mid-20th century with the detonation of the first nuclear bombs, said Ker Than, writing for Smithsonian.com.

The last geologic epoch was the Holocene. It is thought to encompass both the Bronze and Iron Ages. But we do not yet have a tool or material to define our current age. Scientists point to a few specific changes that humans have wrought on the planet. These include nuclear fallout and the rapid spread of materials like aluminum, concrete, and silicon as forensic proofs of humanity’s influence on Earth. 

Plastic “has redefined our material culture and the artifacts we leave behind.” It "will be found in stratified layers in our trash deposits,” said archaeologist John Marston.  

There is no place on Earth that plastics are naturally made. The wide variety of synthetic polymers 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. Plastics are one of the most significant changes that humans have made to the Earth’s makeup, along with the first nuclear detonations in 1945, Andrew C. Revkin reports for the New York Times. 

To add to the problem, most plastics don’t easily degrade, and recycling isn’t an adequate solution. Not all types of plastic are easily recyclable, and there are only a few recycling plants in the United States that can process all varieties of plastic.

This means that much of the materials thrown into recycling bins can crisscross the planet several times before they are processed to produce rugs, sweaters, or other bottles, Debra Winter writes for The Atlantic. 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 fish.

“With a presumed 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. 

Even if human populations worldwide change their plastic-using ways, the damage may already be done. With plastics filling landfills and washing up on coastlines around the world, the Plastic Age might soon take its place next to the Bronze Age and the Iron Age in the history of human civilization.

    A summary of the article is that with so many ages that our civilization has gone through like the Stone Age, Bronze Age and Iron Age it seems that currently our society is incredibly caught up with plastic. Plastic bottles, plastic bags, plastic toys, the possibilities are limitless and not in a good way. Plastic is non biodegradable, which means it can not decompose and go back in to the earth, because thats also not where is came from. Even if you melt it its still a hot, mushy, black blob which also doesn't break down.
    We have been given the beautiful gift that is life but we are ruining it with a simple thing that WE created that might be the case of our ending and downfall.
    It is truly frustrating to think that this is what the world has come to.

    the reason they refer to this time period as the "Plastic Age" because we use and produce so much plastic such as plastic bags,bottles,toys,etc.
