Plastic, Plastic, Everywhere

The Good

Plastic is an incredibly useful material and it has revolutionized our lives.  Plastic is cheap to manufacture and easy to manipulate for countless uses. It can be thin and pliable, or hard and sturdy.  The use of this versatile and handy petroleum-derived material has allowed the mass production of products and has kept consumer costs down.

The Bad

However, plastic has a dark side. As a result of its versatility, plastic has replaced many traditional materials (i.e. wood, metals, glass, stone, paper). Has plastic expanded from revolutionizing our lives, to taking over our lives? More importantly, what are the environmental and health impacts of having this synthetic material literally at our fingertips every single day?

Plastic contains numerous compounds that have been accused of being endocrine disruptors and carcinogens. One of these compounds, bisphenol A or BPA, has been subject to scrutiny because of its likeness to the hormone estrogen. As a result, BPA in plastics has received negative pressure from consumers and has been outright banned in many countries including France.

Besides harmful chemicals, physical pieces of plastic also pose harm to organisms because plastic does not biodegrade, but instead photodegrades. When plastic is exposed to solar radiation, it breaks down into smaller pieces. Pieces of plastic become smaller and smaller until they become microscopic. This means, that although we many not be able to see it, every ounce of plastic ever created is still in existence today!

Solutions

There are many documentaries that focus on plastic and its overwhelming role as a litter nuisance and as troublesome pollution: Plastic Paradise: The Great Pacific Garbage Patch, Addicted to Plastic, Plastic Planet, Plastic Shores, Bag It: Is your life too plastic? An overarching theme to these documentaries is the way plastic pollution is impacting our oceans and marine life. And people seem to be listening.

Clean up projects, like The Ocean Clean Up Project, have huge potential to remove plastic pollution from our oceans. However, these projects only target plastic pollution on the surface. According to the U.S. EPA, only 46% of plastics float. Therefore, these clean up efforts cannot reach more than half of the plastic discarded in our oceans.

 

Just because it is put into the recycling bin, does not mean it is recycled. Rumpke must manually remove all the equipment damaging plastic bags that are delivered to their facility everyday.

Just because it is put into the recycling bin, does not mean it can be recycled by your local facility. Rumpke must manually remove all the equipment damaging plastic bags that are delivered to their facility everyday. In Central Ohio, plastic bags should be taken to your local grocery store drop off.

So, while removing plastic from our environment is important, this only treats the symptoms of a larger problem: our large consumption of single use plastic products. It is important to recycle plastic when possible. However, plastic is a complex material, so to is the complexity of recycling it. Many factors influence the ability to recycle plastic. For instance the type, grade, and purity, as well as what method was used to manufacture the original plastic, can determine whether a municipality can recycle the product.  (Find out what you can recycle in Columbus, Ohio and where to recycle other materials.)

Better yet, we should break the plastic addiction. Reduce plastic pollution by choosing products that do not contain plastic. Choose a reusable glass water bottle over a plastic one. Avoid using single use items made from plastic (i.e. plastic plates and cutlery). Another easy action is to bring your reusable bag to the store instead of accepting a plastic bag for every purchase.  Learn more about ways to reduce your plastic consumption and read about the Zero Waste Initiative.

Anthropology, meet Climatology.

Arctic Ocean

There are more ways to study Earth’s past climate than analyzing the tiny air bubbles in glacial ice cores.

For instance, anthropology. By studying written records left by humans, social scientists can anecdotally model the climate of the past. This information is then used to further strengthen the analytic results of climatologists.  However, pairing qualitative and quantitative data to model climate can only work so long as there exists a human record. Without a human record, prehistoric analysis of Earth’s climate can only be done quantitatively, such as investigating the oxygen isotope rations within ice cores.

Listen to the story below to learn about how social and natural scientists are working together to study Earth’s climate.  (Or visit the NPR story Old Ship Logs Reveal Adventure, Tragedy And Hints About Climate at its source.)

 

Why study something in two or more ways?

Scientists use multiple methods in their research because it strengthens the integrity of the results while providing a more complete view of complex phenomena.
