The Effects Of Dead South American Fur Seals

It has a direct and deadly effect on wildlife. Plastic debris, laced with chemicals is often ingested by marine animals and can injure or poison wildlife. Cattle and other animals are ingesting it, a substance that doesn’t break down, piling up within them. Thousands of marine mammals are killed after ingesting plastic mistaking it for food or getting caught in it. The marine animals mainly affected are: sea turtles, ingesting plastic; seals and sea lions, entangled in packaging; seabirds like the Laysan albatross, ingesting plastic; fish, consume and breath plastic; also whales and dolphins, consume 31% of the marine plastic

The problem with plastic ending up in the ocean is that marine life is being harmed by the presence of it. A study done on the harbor seals in the Netherlands found that more than 12% had plastic in the digestive system (California Coastal Commission). The list of affected species indicates that marine debris is affecting a significant number of species. It affects at least 267 species worldwide, including 86% of all sea turtle species, 44% of all seabird species, and 43% of all marine mammal species (Save our shores). The problem is underestimated because the marine life that ingests plastic or dies from entanglement often goes undiscovered due to the vastness of the ocean, as they either sink or are eaten by predators before they are discovered (Plastic Debris). The potential harm from ingestion of plastics is not restricted to seabirds. Plastic bags drifting on ocean currents resemble the prey of turtles. There is evidence that their survival is being hindered by plastic debris with young sea turtles being vulnerable (Ocean pollution). Over the past 20 years polychlorinated biphenyls (PCBs) have polluted marine food webs at an increasing rate, and are prevalent in seabirds. Though their adverse effects may not always be apparent, PCBs lead to reproductive disorders, increase the risk of disease and alter hormone levels. These chemicals have a detrimental effect on marine organisms even at very low levels and plastic pellets could be a route for PCBs into marine food

The beauty of California is slowly fading away and as environmentalists would say, “There was once a town in the heart of America where all life seemed to live in harmony with its surrounding” (Carson, 366). According to the findings revealed by research foundations in California, marine life is and has been in great danger as a result of plastic remains that accumulates in the Ocean. In his article Daniel Woods states, “Approximately eighty percent of remains found in Oceans are made of plastic that originates from urban runoffs such as plastic trash carried away from landfills, trucks, as well as garbage containers, marinas, ports and construction trash” (Wood, 20). Furthermore, these results also revealed that marine remains where made up of disposable plastic products that constitute food packaging as well as containers that are ever present and contain precious resources that can be used unsustainably. These issues have affected the state critically and have lead me to research the reasons behind the banning of plastic pollution, their economic impact, harm resulting from plastic pollution, as well as federal concerns on plastic contamination.

Sea life can mistake plastic, inedible, objects for food. Sea turtles often mistake plastic bags for jelly fish, which is one of their favorite foods, and quickly die (Geographic). Resin pellets, which are used to make just about anything plastic, are often mistaken for food, especially due to the resemblance with fish eggs. Ingesting hard plastics can easily become lodged in an animal’s intestines or stomach and cause a slow and painful death. These marine animals do not know better than to eat what looks like food, it is not their responsibility to avoid the garbage.

In the article, "Plastic in Our Oceans", Kimberly Amaral discusses the everyday uses of plastic and how it can be beneficial to humans, but harmful to marine life. As fishermen casually dump waste overboard, animals mistake it for food sources, such as a turtle mistaking a plastic grocery bag for a jellyfish. From the trash brought out to sea, gyres, large circulations of water, carry the garbage through currents, spreading it to all over the ocean, specifically to the central gyre. Amaral notes common ways for marine life to die from plastic, which include entanglement by plastic rings, consumption of plastic bags and pellets which stuff the intestines and lead to health problems, and suffocation. As researchers today work hard to discover

Almost 96% of plastic bags are disposed of in landfills (Williamson, 2003). This leads up to another problem as plastic bags are non-biodegradable - in other words, plastic bags do not biodegrade for over a thousand years (Stevens 2001). Plastic bags may also land in farms and in oceans which have an impact on the wildlife. Livestock such as cows may eat plastic bags while grazing. These pose a threat if ingested as they may tangle in their stomachs, causing serious injuries and potentially death (Dreyer et al, 1999; Rasmussen 1999). Each year over a billion birds and mammals die due to the ingestion of plastic bags (Baker, 2002).

A group of researchers studied this at Rio de la Plata, a bay between Argentina and Uruguay. Using satellite telemetry from nine Chelonia mydas the researchers tagged and data on the concentration and distribution of marine waste (accounting only for plastics debris) they created a map displaying the overlapping areas of debris and Chelonia mydas foraging areas (González et al., 2014). The researchers report that the map depicts the average green turtle encountered 9 pieces of plastic every square kilometer of the overlapping areas of debris and foraging (González et al., 2014). Which led to Chelonia mydas accidentally ingesting copious amounts of debris, though death by consumption of plastic debris is rare, the ingestion of chemicals from plastic debris can hinder somatic growth and procreation turnout (González et al., 2014). To gain better understanding how much plastic debris was consumed due to their exposure, the research team examined 62 adolescent Chelonia mydas, 90 percent of the 62 turtles had eaten 13 pieces of plastic on average, 98 percent of it was found in the green turtle’s large intestines (González et al., 2014). While ingestion of plastic debris can have negative effects on the development and reproduction of Chelonia mydas, but two biggest

Over the few years, humans have discarded millions of tons of garbage into the oceans. Ever wonder where the cup you threw out this morning will end up? Or the plastic spoon you used for lunch? How about the cap of a water bottle? The calamitous plastic ends up in the water, taking thousands of years to decompose. The consumption of plastic by the marine life is perilous and the leading cause of death for life on shore.

It is known today that 60% of the plastics being dumped into bodies of water get ingested by animals in the oceans (Center for Biological Diversity, http://www.biologicaldiversity.org/campaigns/ocean_plastics/). Humans use plastics everyday, but what we don’t realize is that after recycling our bottles, they end up being dumped into our oceans where ocean life mistakes a plastic bag for a jelly fish. Today plastics can be one of the main causes of intestinal blockage which ends up clogging the animal 's stomach, not allowing them to digest any kinds of food eventually dying off (Macklin, 2015). Although there is no way that all researchers will be able to prevent

In the documentary “Inside the Garbage of the World”, the main social problem being explained is that there has been a great influx of plastic and other type of garbage in oceans and their beaches. This buildup of pollution has largely affected the wildlife population ranging from animals on the beaches to the creatures of the ocean. In oceans, what is called ‘garbage patches’, a large buildup of garbage that flow to one area in the oceans, are being created. Approximately 50 percent of all plastic sinks to the bottom of the ocean floor but about 2 times that much is actually already on the ocean floor. In fact, according to the documentary, there is a garbage patch that is to the left of California that is the size of half of the United States. Each year, about 4.7 million tons of plastic goes in the ocean a year and it is estimated that by 2050, there will be another 33 billion tons of plastic added to the present amount. Eighty percent of the current pollution comes from the land. According to marine researchers, twice as much plastic debris is one the ocean floor than it was 10 years ago. In the futures, plastic will break down into smaller pieces of plastic, creating a bigger problem from the habitat. This plastic pollution is one of the leading cause for beach and ocean inhabiting creatures be extinct because animals are mistaking these plastic pieces for food. When scientist began to dissect beach animals such as birds, they discovered that at least fifteen pounds of

Even the smartest mammals get caught in situations where plastic looks a lot like food. Most marine mammals get caught in fishing nets because what do fishing nets contain… food such as fish and shrimp. So they end up getting stuck unable to get out because unlike us we have hand that can get us out. They end up living most of their life with plastic wrap around their necks, fins, plastic sticking out of their mouth, and blocking their air way. They suffer throughout their life trying to adapt to the way they used to live before a plastic bag, bottle of water, plastic rings affected them in a tremendous way. Plastic may seem little, harmless even but it does a great deal of damage that can end a life. If plastic was able to break down then just maybe it won’t be as

We 're treating the oceans like a trash bin: around 80 percent of marine litter originates on land, and most of that is plastic. Plastic that pollutes our oceans and waterways has severe impacts on our environment and our economy. Seabirds, whales, sea turtles and other marine life are eating marine plastic pollution and dying from choking, intestinal blockage and starvation. Scientists are investigating the long-term impacts of toxic pollutants absorbed, transported, and consumed by fish and other marine life, including the potential effects on human health.

Ten of thousands of birds, seals, and many more are killed from plastic bags. This is because these plastic bags are being mistaken from being jellyfish. In the text, How Plastic Bags Affect Wildlife by Animal Friends Croatia, it states, “Plastic bags, once ingested, cannot be digested or passed by an animal so it stays in the gut.” Plastic in an animal’s gut can prevent food digestion and can lead to a very slow and painful death.” Plastic contains BPA which is being thrown into the ocean. BPA is a toxic chemical made from a factory to make plastic bags. Marine animals such as sea turtles and many fish are consuming this toxin. In the article, OCEAN PLASTICS POLLUTION- A Global Tragedy for Our Oceans and Sea Life written by Center for Biological Diversity, it says, “Fish in the North Pacific ingest 12,000 to 24,000 tons of plastic each year, which

The image above obtained from Bing images illustrates the death of an albatross bird that has consumed plastic waste from the ocean.

Due to their regurgitation ability; most studies have focused on the ingestion of plastic pollution by bird, this does little harm to birds used in the studies. The effects of ingestible plastic on fish have not been studied as thoroughly and no studies have been conducted on filter-feeding organisms, which do not possess a feeding mechanism which would allow them to distinguish between plastic and plankton. Plastic pollution is only getting worse due to increasing population of developing countries. A wide variety of marine species is known to be harmed by plastic debris. This could threaten the survival of certain species, especially since many are sadly endangered by other types of anthropogenic actions.
