What Are Plastics Doing to The Ocean

Plastics are a wondrous group of materials. They can be as soft as a pair of nylons or as solid as a sewer pipe. What’s more, they’re easy to create – and difficult to break down. This is great for manufacturing durability but hard on Planet Earth. Now we find ourselves trying to reshape our love with disposable plastics through changing what they are made of, how they are used, and where they end up. Technological breakthroughs promise ways that we can make the most of this miracle material without it harming the environment.

 

The great pacific garbage patch

The North Pacific Subtropical Gyre is an oceanic dead spot – a calm eye at the heart of currents flowing around the vast ocean. It’s also the last stop on an oceanic spin cycle, trapping any debris that falls in or floats away. Old shoes, milk jugs, grocery bags, and more create a plastic and seawater soup. Our love of plastics has changed the pacific gyre into the Great Pacific Garbage Patch, a virtual sea of abandoned plastic. Clever engineers are developing new technologies to gather and isolate this floating debris to help clean the ocean – one important step in the worldwide process of reducing plastic waste in our landscapes and seas. The best method to reduce the garbage patch remains the simplest: Use less plastic.

Animals are killed every year by plastics and disposed nets.

Plastics are not only all around you. They’re also in you and on you. They come from plastic microbead ingredients in commercial products – toothpastes, exfoliants, and other items – that have been on the market for decades. Some countries like the United States and the United Kingdom are now banning microbeads in personal products but leaving commercial and industrial use untouched. As such, the ocean receives a dump truck’s worth of plastic pollution every minute. Other microplastics form when plastic waste breaks apart into small pieces in the environment. Unlike larger ocean debris, these microscopic pieces can’t be collected by any net, and they often wind up entering the food chain.

Bioplastics could be the healthiest alternative to general plastics.

plastics are key by-products of the world’s oil and gas industry. Over 4 percent of all global oil and gas production goes to make plastic products, many designed for disposability. The things we plan on throwing away are made of the material least likely to decompose. Now material scientists believe that they have an answer: bioplastics. Made from pulped plants instead of fossil fuels, bioplastics use the sugar in corn, beets, or sugarcane to create the long chains of molecules needed to make plastic. Because they are made from organic plant material, they can be composted after use and turned into soil. Bioplastic cups, cutlery, and even trash bags are already on the market – and making a difference.
