What is plastic pollution?
Plastic pollution is the accumulation of plastic that is becoming a huge global problem. Plastic pollution is affecting our waters and environment overall. Today, I will be discussing the different types of plastic that are affecting our oceans, the amount of plastics circulating our oceans, the harmful effects of plastic pollution, and the current obstacles our world is facing today and several solutions that can help decrease the amount of plastic polluting our world.
The beginning of plastic pollution
Plastic is one of the most frequently used material for everyday conveniences. Think about every plastic piece you use starting from using grocery bags, food containers, coffee cup lids, to drinking out of soda bottles. According to Ivar do Sul, the author of Present and Future of Microplastic Pollution in the Marine Environment, an inventor named Hyatt introduced plastic during the 1870s. The breakthrough of this material became popular due to it's ability to shrug off water and oil and there was a significant use of plastic by the 1940s when companies had machines to mass-produce plastic products. Although the introduction of plastic was a significant invention for America, the harmful effects caused by the build up of plastics soon became evident.
Types of plastic
Plastics come in all different sizes and are built with different materials that damages the environment in their own ways. The first type of plastics are microplastics. The journal, Microplastics: Addressing Ecological Risk Through Lessons Learned, microplastics describes microplastic as micron size and most commonly used in facial cleansers, cosemetics, or in air blaster medias for cleaning rust and paint of machinery and boat halls (Syberg, Kiristian, et al. 945). The second type are plastic fragments that come from broken down pieces of plastic that can be seen. Regardless of the plastic are mircosized or fragments, Krisitian Syberg states that, "microplastics can attract a wide range of pollutants, possibly altering their bioavailability, fate and flux into their environmental compartments." Due to the size difference, these two categories of plastic are also recorded differently.
Causes of plastic build up
Countries like America, use an abundant amount of plastic for many reasons. First, plastic is inexpensive and easy to produce. It is stated in the journal, Present and Future of Microplastic Pollution, that plastic are made out of polymers that help plastic to be malleable, durable, and light (Ivar do Sul, Juliana A., and Monica F. Costa). The polymers that are used to make plastic attract other chemical pollutants onto their surface and act as reservoirs of toxic chemicals in the environment.
Recording the amount of plastic
There are several ways scientists are recording how much plastic is floating in our waters. One way is to record and keep track of how much plastic pellets are consumed by certain species of animals. Stated in the Seabirds, Gyres and Global Trends in Plastic Pollution journal, scientists are able to record the amount of plastic that is floating in the ocean by closely observing the plastic that is inside of a Fulmar and the North Atlantic Gyre's stomach. These species of birds are a unique species of birds that survive mainly deep out in the oceans and only come to land to reproduce. After collecting data of the pellets inside the bird’s stomach, is stated in Seabirds, Gyres, and Global Trends in Plastic Pollution article, that “there around 270,000 tons of micro and macro plastic debris floats in the global oceans. That quantity represents only about 5% of the minimum of the estimated annual input of plastic waste into the oceans from land” (Franekar and Lavender Law 93).
Current Situation and problems of plastic build up
Today, studies like the one explained above are still being used but Ecological Risk Through Lessons Learned also summarizes that, “Science is lacking to support evidence-based decision making with respect to ecological exposure to, effects of, and risks posed by microplastics” (Syberg, Kristian, et al. 949). So this means that there isn’t a clear answer to the harmful and toxicological effects that could occur in the future because of the build up of the plastics. It also demonstrates that more studies should be done on the collection of these plastics because it can have a chain ball effect later in the future when they all add up.
taking hundreds of years to degrade and usually contain additives that pollute the ground and when when released.” (Jakovcevic et al. 372).
The ingestion of microplastics by smaller animals soon move onto bigger predators and other species and eventually to individuals who consume these fishes. This makes individuals susceptible to physical damage if consumed in high dosages. Not only does it affect the marine species but microplastics also make its way up to the sea surface where land animals can be affected.
he Ecological Risk Through Lessons Learned article states that, “Microplastics can attract a wide range of pollutants, possibly altering their bioavailability, fate, and flux into other environmental compartments.” It also talks about how plastic with different additives change their physical attributes that can leach into the environments in different ways. In addition, microplastics can cause physical impairment by being caught in the organs of animals and other invertebrates; thus affecting ventilation and feeding activity.
Despite the lack of study done on the effects of plastic buildup, what scientists are sure of is that the amount of plastic floating in our waters have been decreasing. It is stated in the, Seabirds, Gyres, and Global Trends in Plastic Pollution article, that there has been a decrease in pellets which suggest that “floating plastic debris is rapidly ‘lost’ from the ocean surface to other as-yet undetermined sinks in the marine environment” (Franekar and Lavender Law 89) Although scientists found that there are less plastic debris floating around and less pellets inside of these bird's stomach, there is still no explanation to where these plastic debris end up. And despite the fact there is a decreased amount of plastic floating in our waters, it does that mean that current levels of plastic do not cause harm to food chains or ecosystems. An example of this problem can be clearly seen through the Great Pacific Garbage Patch in the Pacific Ocean.
