The Effect Of Pollution : The Dangers Of Sea Turtles

All over the world there is a subject that has an effect on us all, and that subject has come to be known as climate change, or more commonly global warming. Climate change has a huge impact on Sea Turtles and their nesting grounds. Specifically referring to the Sea Turtle’s ability to reproduce. Especially within the last ten to fifteen years.

Attention Getter: According to Tilley, K. (2013, August 26) More endangered sea turtles ingesting plastic, there are almost twice as many endangered green sea

Turtles are one of the oldest reptile groups. They are classified as amniotes. They have existed a long time ago, which means they have seen the rise and fall of the dinosaurs and the rise of humanity. Scientists think that turtles have existed for around 157 million years (mosaic 29). Approximately, sea turtles were 65 million years ago (Dobbs 1). This family has survived the passage of time and is threatened by the contamination that humans have created in the ocean. The six sea turtles that occur on the coasts of America are in fact threatened. Sea turtles are very important for the ecosystem, but humans, directly and indirectly, endanger this family. If humans do not stop their destructive habits, we can lose the influence of sea turtles on seafarers. Sea turtles play an important role in the ecology of the ocean, and without turtles, we can see an ecological collapse in the oceans. Sea turtles are one of the few animals in the sea that eat sea grass (Godfrey). Sea turtles act as grazing animals that cut short grass and help maintain the health of the family of seaweed (Godfrey). In recent decades, there has been a decline in the sea grass family. This decrease may be related to the decrease in the number of sea turtles (Godfrey). Sea grass is important because it is a fertile ground for many species of fish, shellfish and crustaceans (Godfrey). The beaches and sand dunes are known for not having many nutrients. When the sea turtles reach

Humans have heavily affected sea turtle mortality rates, but one may ask what the benefit of having a stable and healthy population of sea turtles is. Sea turtles hold many important roles in both terrestrial and marine ecosystems where they are found. Along coasts where sea turtles are found nesting, beaches have been seen to have an increase in organic matter, phosphorus, nitrogen, and lipids (Bouchard 2000). This matter left by the sea turtle is in the forms of unhatched eggs and eggshells, which are then brought into the food chain through decomposers, such as beetles, or sea turtle predators, such as crabs (Bouchard 2000).

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.

The leatherback sea turtle, Dermochelys coriacea, belong in the phylum of Chordate, class of reptilian, order of Testudines, and the family of Dermochelyidae. These reptiles can be found throughout the Pacific, Atlantic, and Indian Oceans. Leatherback sea turtles are the largest turtles in the world. The average life expectancy of a leatherback turtle is forty-five years. Average size of the turtles upper shell, carapace, is about five feet and has a rubber-like texture feel to it consisting mainly of oil-saturated connective tissue. On average Dermochelys coriacea can weigh any where from approximately six hundred to two thousand pounds. In length these turtles are typically fifty-five to seventy-nine inches. The lack of claws is another distinguishing

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

The Chelonia mydas also known as the green turtle is currently classified as an endangered species and is one of the oldest living marine vertebrates. The aim of this paper is to examine the Chelonia mydas the chain of events that has caused the decline of its population primarily through human activity, diet, and relationship to its ecosystem. The paper will conclude with a discussion of current conservation efforts implemented to save the Chelonia mydas population. Such efforts include restrictions on human hunting and Identification of marine areas for conservation via satellite tracking.

Moreton Bay and Tangalooma is the third largest local government in Australia by population. It covers more then 2000 square kilometres and serving nearly 400,000 residents. The council has more then $4.4 billion worth of assets under management. On March 11th 2009, a container ship in the Pacific Ocean lost over 31 containers overboard, it had leaked approximately 270 tonnes of oil 11km off east of Moreton Bay. Their wasn’t many wildlife that was effect from this oil leak. The animals that were effected was treated, cleaned and then released. In Moreton Bay and Tangalooma over 200 turtles are being reported dead, sick or injured. The debris and plastics in the ocean doesn’t just effect the marine life but it also effects human health. Turtles can be very weak due to their downward facing spines, which causes them to swallow their food easy but cannot bring it back up, which paralyses the turtles gut from digesting their food. Most of the pollution that enter the waterways of Tangalooma and Moreton Bay are being flushed into the Bay’s, which is actually impacting the water quality and health of Moreton Bay and Tangalooma. By more and more pollution entering the water ways of the bay’s it can increase the cause the turbidity, nutrients and algal blooms, which can cause the loss of seagrass and a loss of food sources for the turtles and other marine

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

Sea turtles are becoming more and more endangered as time goes on and is something that really needs to be changed. There are seven species of sea turtle and they are all either endangered or critically endangered. Millions of sea turtles used to inhabit the sea now only a fraction of them are still around. Humans are partly the cause of this because we hunt them for food and profit. It is unbelievable that people can kill such beautiful creatures just for their personal benefit. Humans are not the only reason sea turtles are facing extinction, but we are the main reason. Humans really should not be part of the problem in the first place.

Sea turtles have been a big help in maintaining the health of the world's ocean for more than 100 million years. They help by keeping up coral reefs all the way to transporting nutrients to beaches. Major changes have occurred in oceans everywhere due to the decline of the sea turtle population. Oceans are unhealthy because of this. It is time for us to protect the sea turtles and rebuild their population to ensure healthy oceans in the future. According to oceana.org, there are seven species of sea turtles that roam the world, six of which inhabit U.S. waters, and have been listed as either endangered, or threatened. Up until now, all six of these species are not at a healthy level despite protection measures from the Endangered Species Act (ESA). Some populations even continue to decline. Even at a diminished population, sea turtles play an important role in ecosystems. They are also extremely important to humans because they keep oceans healthy, and we use the ocean as a food source. They keep up the health of the ocean in many different ways, all of which, are very important.

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

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.
