Where does all the plastic go. Every bit of plastic that has been created is still here. This is because plastic is one-hundred percent non-biodegradable! Even the most degraded plastic down to polymers cannot be digested by bacteria (Laist, 1997). If global issues like starvation and climate change are not enough to stress on, the weight of an issue literally churning in the Pacific Ocean is startling. For decades the majority of the world’s population has not been properly educated on the nature of plastic and the potential harm it can do to our environment and our physical health. Due to factors of man and the natural effects of nature, a major problem has developed that is now harming our food.
Marine plastic is a visible sign of human impact on the marine environment. Plastic debris is more than an aesthetic problem. It can potentially cause danger to marine organisms through ingestion and entanglement (Laist, 1997). There’s so much plastic out there that it’s starting to compete as a food source for many different organisms. Plastic eventually breaks down into food size pieces and is mistaken for food by many organisms. They mistake the plastic particles for plankton. The public has a desire for certain types of fish which happen to have an accumulation of different toxins in their body. This happens when those larger fish species eat large amounts of smaller fish and other organisms that feed off the plankton-plastic mixture. Plastics are toxins can de-absorb out from the plastic and into the tissue and organs of the fish that are eating those smaller fish. The toxins move up the food chain becoming dangerously concentrated. Decades ago the number of marine mammals that died each year due to ingestion and entanglement ap...

The Great Pacific Garbage Patch is the largest garbage dump in the world. According to estimates made by experts, the patch holds approximately three and a half million tons of garbage. Majority of this garbage is made of plastic. This waste is a threatening problem to the patch’s surrounding wildlife. Many animals are caught in the floating pieces of trash and it is the cause of the deaths of about one million birds and about one hundred thousand other sea animals. Due to the oceans nature and constant moving currents, the trash is also constantly moving. Therefore the size of the patch never stays the exact same. However, scientists believe it be approximately two times the size of Texas. The plastic is mostly broken down from larger materials into small pieces. The patch has been referred to as one scientist as a, “plastic soup”. This garbage poses such a threat mainly because it does not biodegrade. These plastics will be in the ocean essentially forever. Many plastics also contain chemicals, and absorb other chemicals and pollutants they become exposed to. These newly absorbed toxins are then leaked and distributed back into the ocean over time. The chemicals can directly enter the bodies of the animals which consume them. A study was being conducted by scientists of the fish that inhabit the area around the patch. What the researchers found inside the belly of one fish (that was no larger in size than that of a finger), was eighty four small fragments of plastic. It does not take scientists to recognize the impact of this problem, Zach Gold, who is sixteen, is from Santa Monica California. Zach enjoys s...
Which means their obviously bad for the aquatic marine life environment & are cause many different forms of damage for them & us as one. On p.g. 23 of The New York Times upfront magazine “Birds,fish, sea turtles, & others are getting tangled in plastic bags or mistake them for food & choke”. Someone else might argue that they could the plastic bags in landfills instead of oceans. But that counter- argument is flawed because you’re just polluting by burning plastic which is bad on our part we’re not doing our part to support & taking care of the earth. Plastic in the ocean isn't just bad for plants & animals but for humans too because of the food chain some of us eat animals as a meat source such as aqua marine life like fish. If the fishermen catch fish that have been eating plastic then it's in our food supply if we eat that fish it's gonna be bad for us so many will end up getting sick from the plastic inside of the fish then what will we do our aqua marine food supply will go down the drain we couldn’t eat the fish since it's basically contaminated with plastic that we’re dumping there instead of trying to fix it & getting rid of plastic bags for good for the good of the earth. We’re causing damage towards the earth by dumping all that plastic into the ocean which damages our water supply it’ll poison us although we clean the water it depends on how big the plastic particles are, it’ll make us sick & sense it’s been lying in the oceans could bring in new pathogens &
Throughout the country one might find themselves seeing a plastic bag floating around or even stuck in a tree. This is a problem that most want to eliminate. A topic that Mangu-Ward writes about is the problem of plastic bags in marine life and other wildlife. For people the thought of animals dying angers them. These decisions that people are making currently are emotional decision as Mangu-Ward describes them. Many marine life animals have died from the cause of littering of the plastic bag. Mangu-Ward writes, “plastic bags make up 3.8 percent of beach litter”. Finding fish, turtles, and many more marine and wildlife animals with plastic bags either suck around their necks or in their throats is something that many do not like to see or hear. This evidence can also be supported when Mangu-Ward writes, “1 million birds and 100,000 marine mammals and sea turtles die each year from eating or getting entangled in plastic”. Mangu-Ward is currently giving evidence that plastic bags are bad for the

Recently, an uninhabited island in the South Pacific Ocean was found to be polluted with 38 million pieces of plastic that had been carried over by currents (Wang, “No one lives on this remote Pacific island”). The island, dubbed ‘trash island’, is home to diverse animal populations that have all been devastated by the pollution. On the beach, hundreds of birds were seen dead by reporters and scientists. When analyzed, the primary cause of death turned out to be consumption of plastic. When animals ingest plastic, it clogs their stomach and poisons their body with toxic chemicals. These toxic chemicals cause an array of issues, such as reproductive and endocrine problems. Eventually, this leads to death (Knoblauch, “The environmental toll of plastics”). But due to the nature of plastics, it can take hundreds or even thousands of years to completely degrade, meaning that as plastic pollution continues to build up, more places like ‘trash island’ will be discovered. According to conservation scientist Alex Bond, “…[The island] is just an indicator of what’s floating around out there” (Wang, “No one lives on this remote Pacific
Most of the necessities humans need are provided in supermarkets, in fact supermarkets have become a necessity for our everyday life. They are now the main source of water, food, clothes and everyday tools. Therefore, the plastic bags demanded and supplied in this industry increase every day. In the past decade, we produced as much plastic as we did in the whole twentieth century (Freinkel, 2011). This exponential increase of a non-biodegradable material has negatively impacted our environment immensely. Plastic production requires our dwindling fossil fuel resources, robs away animal lives, litters our beautiful landscapes and even affects our very own well-being. Hence, if plastic production doesn’t diminish immediately, we will suffer great

According to a study conducted by the University of British Columbia, approximately “93 percent of beach fulmars (migratory seabirds related to the albatross) had bellies full of plastic, with one even having upwards of “454 pieces of plastic in its stomach” alone. (Source B) Similarly, in a 2011 International Coastal Clean-up, there were 964244 plastic bags found in the ocean, each having the potential to kill wildlife (Source C). A major reason as to why plastic bags are so hazardous to animal health is the fact that they have no biodegradable capabilities, meaning that instead breaking down into organic materials, plastic takes 500 to 1000 years to simply photodegrade, fragmenting into smaller pieces but not presenting any less danger (Source F). As these pieces become smaller, making it easier for any animal life, marine or not, to ingest it and suffocate as a result of the blockage. This is when the implementation of a tax on plastic bags could become extremely useful as a method of regulation and

... coastal ecosystems and even distant marine food webs, due to their ability to interact with and exchange biomass and energy. Whether it be primary or secondary production that plays the more vital role is still up for debate. It is clear that that increasing stress from human activities will inevitably have far reaching effects on the linkages that exist between the various habitats discussed. More studies are needed to provide quality quantitative data at other sites around the globe especially those that have not yet been studied. It is also necessary to determine the extent and importance that the numerous habitats evaluated in Wong’s study currently have on neighboring as well as distant ecosystems for which they may have valuable connections with. This data could provide important insights that could then be better compared to the research presented by Heck.

When the plastics enter into the oceans, some young fish are drawn to them, and seem to think that it is food, and they end up preferring the plastic to their natural food sources which eventually starves them before they can reach their reproductive age. The microplastics have been found in the bodies of whales, seabirds, and fish. Marine organisms ingest the particles, but they are unable to digest them, this leads to a buildup in the digestive tracts of the animals which hinders the microorganisms from taking in more food, and it diminishes the organisms feeding stimulus which can lead to starvation (Fossi, M. C, 2014). Studies have proved that the physiological consequences of crabs taking up polystyrene microspheres through their gills are minimal. When the crabs inhale polystyrene microspheres into their gills chambers, it leads to a small but temporary change in ion regulation and oxygen
Plastic or paper, is a choice that people face when going to the grocery stores. Plastic bags are often the choice that is made. A controversial issue in the world today is the use of plastic bags. Plastic bags are used because of the convenience they give, by being able to carry several items at once. However, in the article, “Banning Bans, Not Bags”, Jennifer Schultz claims, “Plastic bags clog up local waterways, litter roadways, and get swallowed up by unsuspecting fish” (6). Plastic bags are used once, then are discarded or, littered all over the place. When they are littered all over they become problems for more than just humans. These plastic bags pose a big hazard for animals on land and in especially the ocean. Humans eat land and

Although plastic bags appear to be fragile and light, their negative environmental effect is devastating. Plastic bags may cause large amounts of pollution in every step of their limited life cycle, from the extraction of raw materials, production, transportation, and recycling or disposal. Plastic bags can be defined as the most damaging form of environmental pollution. They can have a damaging effect on marine animals and wildlife in addition to the aesthetic effects on beaches, parks, and trees. Plastic bags are potentially one of the main causes of death to marine animals (Harbor keepers,2008). Up to one hundred thousand marine animals or more die each year from eating plastic bags which are mistaken for food. This can result in blocking the animal’s intestines and possibly lead to the animal’s death. Another possible situation is that wildlife, such as birds, can get tangled in plastic bags causing choking and immobility, which may eventually lead to death. (Senior, 2008) and (Citizen Campaign, 2010). In other situations, after plastic bags photo degrade they remain toxic and could be eaten by fish, shellfish or any other marine life and survive this allows the toxins to enter our food chain through bioaccumulation (Puget Soundkeeper Alliance, 2011).
