Chemicals; the Good, the Bad, and the Harmful
In the early 1900’s scientists from different backgrounds, labs and companies were experimenting on their various products. One would pick up on the compounds of another and add or take away a chemical or two and by the 1950’s the fantastic product that we know today as plastics had evolved and was on earth to stay. Plastic material was soon found in every type of industry around the globe.
Plastics in one form or another during its evolution have been and are still good for human use regarding the quality and comforts of life that it offers. I would not want medical professionals to still be sterilizing needles or washing syringes to give me a shot or to be examined by a dentist or doctor without gloves. I want new single use sterilized needles and new gloves. There is too much room for error and too many new germs out there. Imagine taking medicine in a hospital setting without those little plastics disposable cups filled with clean water. What would we do without food storage and freezer bags, plastic wrap for covering cooked foods, individualized wrapped foods for protection and freshness on the store shelf? Imagine how much cleaner our garbage disposal systems and communities are due to using those large plastic garbage bags to dispose of household garbage. How many diseases have decreased because of better sanitation methods due to plastics? I doubt anyone will ever be able to determine a statistic measuring the good that plastics brought into our world. We can only relate somewhat to the great impact that plastics have made. Another thing that would be impossible to do is to list all the types of products made from plastics. The number of items is just immeasurable. No doubt about it, plastics have impacted each of our lives in many positive ways. Plastic is not the enemy in this discussion, but one of the most common products we use that unfortunately is frequently made of some questionable chemical compounds.
As my recycling efforts continue, I have been surprised to find that I recycle more plastics than anything else. I thought as I began recycling that cans would be the most recycled item or maybe paper. I also have been noticing how much plastic and other trash, usually food and drink containers, is left on the side of the road, in parks, parking lots, around and in lakes, oceans, just about everywhere. This fact brought about the question how does the chemicals in plastics affect humans and how does it affect wildlife as they run into it in their habitats?
The answer regarding potential harm to humans has become the subject of many research studies and some will be summarized in the next blog. The harm for animals takes several forms and any type of plastic is potentially dangerous to animals. Sadly, harm to animals could be prevented if humans would only properly dispose of plastics and other trash. The majority of plastic related mishaps with animals involve the animal getting its neck legs, wing, head or other body part caught some way with plastic items and cannot get free. Many animals die because their entanglement remains if a human doesn’t come along to help. For example our golden retriever recently had a bottle cap wedged in his gum. It was in the back of his mouth and by the time it was obvious to us that he needed a vet’s care, the cap was imbedded in the gum with a serious infection and had to be cut out. We had no idea it was even there. Another way animals get into trouble regarding plastics is by ingesting some plastic object or bit of plastic that may end up choking them or harming their digestive system. All animals are susceptible. A quote from Wildlife Stewardship on the website http://www.centerforwildlifeinformation.org emphasizes this, “Animals will eat anything with an odor including aluminum foil, plastic and other food wrapping. These can severely damage an animal’s digestive system and may even facilitate death.”
Examples of animals coming into harms way due to human neglect is birds and marine animals getting caught in fishing line or nets that became hung up and left in trees or caught on something under the water. At http://www.News.NationalGeographic.com, it is stated that 44% of all seabirds eat plastic by accident. I’m sure many other wild birds do the same. Little bits of Styrofoam after all to a wild bird will look like a seed. This site also claims that 267 marine species are affected by plastics that are left in lakes and the oceans. It also stated that larger fish will swallow a grocery bag whole as it looks like a jellyfish.
Another way of potential harm to animals is by how the chemicals within the plastic harm the soil or environment around them. The article, Plastic Breaks Down in Oceans After All–And Fast, on the National Geographic website listed above shares information about this new discovery. It states that unlike what was once believed, plastics do not last for years in the ocean, but the chemicals in plastics begin breaking down within months. The chemical that is harmful once the plastic breaks down is styrene trimer, a polystyrene (plastic) by-product (suspected to be a carcinogen) and bisphenol A (interferes with reproductive systems in lab animals) which is found in hard plastics like water bottles, baby bottles, linings of aluminum cans and other containers. The article described our oceans as “Plastic Soup”, a toxic soup at that.
The oceans are not the only place where environmental hazards exist for animals and humans. Toxic wastes dumped wherever always has the potential to be harmful sooner or later, according to how it was disposed. Also gases and toxic fumes are still polluting our air. While these problems are a major concern and government agencies, researchers and scientists work hard every day to rectify what they can, chemicals remain one of the most serious pollutants. Plastic items just happen to be one if not the most common commodity made from some of these potentially harmful chemical compounds. But most people could not imagine living without at least some plastic items and I’m one of them.
Almost everything has a positive and negative side, chemicals certainly do as well. While chemicals are necessary for many of the comforts of life we enjoy, they also present problems for the environment. Let’s just face it; there will continue to be an ongoing task for society to clean up the environment. We’ve just got to keep at it. All these thoughts bring about the question; is there another cleaner and greener alternative perhaps commodity items made of chemicals that are good, not bad, not harmful, maybe?
