Now with microbeads.

The Small-Scale Plastic Causing Large-Scale Problems: Microbeads
Greenberg steve@greenberg-art.com

Since the Industrial Revolution, the business of plastic production has skyrocketed from almost nothing to hundreds of millions of tons; 1.5 million metric tons in 1950 and nearly 300 million metric tons in 2012. Staggering quantities of this plastic has been documented entering rivers, lakes, and oceans since the 1970s, infiltrating all marine ecosystems. Worse yet, the problem continues to grow.


What Are Plastic Microbeads?

In ten words or less, microbeads are really tiny pieces of nonbiodegradable plastic. To be more specific microbeads are usually classified as plastic particles smaller than two millimeters in size. The composition of plastic varies from product-to-product. Most commonly microbeads are made up of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polymethyl methacrylate (PMMA), otherwise known as nylon. These synthetic plastic particles are found in several household products, most commonly, personal care products. Ranging from facial scrubs to toothpastes, when these products are used and rinsed down the drain, microbeads are often too small to be caught by the filters of wastewater treatment facilities. As a consequence, these bits of synthetic plastic are simply flushed directly into our lakes, rivers, and streams, eventually making it to our oceans and invading all marine ecosystems. A single tube of facial scrub can contain more than 300,000 microbeads.


The Microbeads In Our Waters

Fun (or not-so-fun) fact: Marc Ward from the Sea Turtles Forever Blue Wave Team filtered more than half a pound of plastic from one square meter of water at Crescent Beach, Oregon in 2012.

Another not-so-fun fact: an estimated 470 million microbeads pollute the San Francisco Bay every day. That means in a years time approximately 172 billion microbeads have entered the San Francisco Bay alone. In one year, the San Francisco Bay's microbead population is 24 times the world's human population of 7 billion.

Once at sea, the plastic of microbeads often breaks down into even smaller pieces, but it still doesn’t "go away”. Only about 10 percent of this plastic remains visible while the rest becomes buried under the sand. Microbeads then find a new home in the landscape of marine ecosystems, some sink to the ocean floor while others wash up on beaches. The remainder of microbeads is eaten by fish and marine birds. There are many recent records of microbeads being found in creatures such as albatrosses and sea turtles. As may be expected, these synthetic plastics act as health hazards . Microbeads can have the instant effect of causing animals to choke, suffocate and die. Or the prolonged effect of getting into a creature's digestive tract, causing decreased energy, slower growth, and lower reproductive rates.



The Microbead In Our Food

Once microbeads are unleashed into our waterways, they can make their way up the food chain all the way to the human level. You may be thinking there's no way the piece of cod fish I'm eating for dinner has been contaminated by plastic, but yes, chances are it has.

Beginning at the bottom of the food chain, so to speak, studies have recently found that microbeads are small enough for even plankton to ingest. Plankton remain a massive food source for smaller species of fish. Fish species that humans harvest for food have been known to eat, not only these "infected" smaller fish, but also micro-plastic particles themselves at an alarming rate. The toxins absorbed in plastics transfer to fish tissue, the same fish tissue that makes up your sushi. Plastic microbeads absorb persistent organic pollutants such as pesticides, motor oil, and other industrial chemicals. A single microbead can be up to a million times more toxic than the water around it.


Stopping The Spread Of Microbeads

The first step is to be aware. Most people have no idea the little beads marketed as exfoliators are actually bits of plastic. In the United States, The Food And Drug Administration (FDA) requires that if a product contains microbeads the company has to list the ingredients. If you see any of the following ingredients: polyethylene, polypropylene, polyethylene terephthalate or polymethyl methacrylate, you’re cleaning up with microbeads .

Right now, about 18 states in the US, Canada, Australia, and several countries in Europe are considering bans of products that contain plastic microbeads. The Canadian federal government has announced it's intentions to classify microbeads as a toxic substance within the Canadian Environmental Protection Act and introduce new regulations. Unilever announced in 2012 to phase microbeads out of the production of facial scrubs and exfoliators by 2015. Johnson & Johnson is working towards removing all microbeads from their products by 2017.

Every Girl Needs To Listen To 'She Used To Be Mine' By Sara Bareilles

These powerful lyrics remind us how much good is inside each of us and that sometimes we are too blinded by our imperfections to see the other side of the coin, to see all of that good.

Every Girl Needs To Listen To 'She Used To Be Mine' By Sara Bareilles

The song was sent to me late in the middle of the night. I was still awake enough to plug in my headphones and listen to it immediately. I always did this when my best friend sent me songs, never wasting a moment. She had sent a message with this one too, telling me it reminded her so much of both of us and what we have each been through in the past couple of months.

What's your sign? It's one of the first questions some of us are asked when approached by someone in a bar, at a party or even when having lunch with some of our friends. Astrology, for centuries, has been one of the largest phenomenons out there. There's a reason why many magazines and newspapers have a horoscope page, and there's also a reason why almost every bookstore or library has a section dedicated completely to astrology. Many of us could just be curious about why some of us act differently than others and whom we will get along with best, and others may just want to see if their sign does, in fact, match their personality.

Being a good person does not depend on your religion or status in life, your race or skin color, political views or culture. It depends on how good you treat others.

We are all born to do something great. Whether that be to grow up and become a doctor and save the lives of thousands of people, run a marathon, win the Noble Peace Prize, or be the greatest mother or father for your own future children one day. Regardless, we are all born with a purpose. But in between birth and death lies a path that life paves for us; a path that we must fill with something that gives our lives meaning.
