The Danger in the Sea: Negative Human Impacts on Marine turtles

Now, as most may know sea turtles are both marine and land animals depending on what stage of life they are in. Which means that they need to be able to go on land during certain stages of their lives. One of the main reasons why a sea turtle will go on to land is to lay their eggs. Within the last few years this has become harder and harder for the already endangered species. It

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

This litter that ends up in the ocean is consumed by many animals. There are about seven different kinds of sea turtles and the world wild life organization is working on conservation on five of them. What’s happening to all of these turtles? Due to debris in the ocean the turtle are getting tangled in the six ring bottle or can holders and getting them stuck around the middle so

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).

This project will help me to make connections with the world because I will be working with one of the most-well known organization on Maui. I will learn more about turtles and their habitats. This will challenge me because I will need to dedicate my time during the week. This means I need to organize my time and plans. I have a list of five questions that will be answered to finish my project. These questions are: How do turtles hatch their eggs and how it looks like? What can we do to help turtles? What does turtles do in their daily life? How many turtles still remain in Hawaii? How much does turtles affect our environment?

The Red-bellied Cooter is being threatened by both man-made and natural causes. Do to economic growth, areas that used to be a good habitat for these turtles are now being turned into new, buildings like apartments, houses, and stores. In areas where the turtles can live, they are threatened before they have even hatched from their eggs by other predators like raccoons, skunks, or even snapping turtles. Almost all of the eggs in a nest are harmed before they have a chance to hatch. So while humans taking up land takes the Red-bellied Cooters’ homes, their predators take their lives.

The magnificent leatherback sea turtle is a precious species that exists in the world today. It has endured and evolved through the years, and it would be terrible if humans put an end to their amazing existence. By learning more and taking an active role in supporting conservation programs, hopefully the leatherback population can grow and

The green sea turtle occurs throughout tropical and subtropical oceans and is among the largest of the hard-shelled sea turtles growing to as much as 440 pounds and four feet in length. The breeding populations in Florida were listed as endangered in 1978 (43 FR 32800 32811, July 28, 1978) whereas all other populations were listed as threatened (NOAA 2015h). There is a proposal for identification of a North Atlantic green sea turtle distinct population that would be listed as threatened, continuing its current listing status near New York (80 FR 51763 51764, August 26, 2015). They are found in the shallow waters (except during migration) of shoals, bays, lagoons reefs, and inlets, often where submerged aquatic vegetation exists, from Maine south to Florida, and throughout the Gulf of Mexico and the Caribbean Sea (USFWS 2015n, 2015o; NOAA 2015e). Green sea turtles nests are not present in New York; however, they occasionally are found stranded on or near the shore (NYSDEC 2015ad). Breeding takes places in subtropical to tropical oceans every two, three, or four years between June and September, with peak nesting in June and July (NOAA 2015h; USFWS 2015u). Hatching usually occurs at night, and many green sea turtle hatchlings seek refuge and food in masses of floating sea plants (USFWS

The lighting causes many turtles to die by leading them away from the moon which can cause dehydration, getting run over, Etc. There are turtles being born each year and 100-300 turtles are dying each year due to the lighting on beaches. If the turtles are being affected by lighting on the beaches many things could happen. A few examples are that the turtles will soon be extinct and we soon will not be able to see their beauty. The other animal rates could go down also because some of the animals need to eat the turtles to survive. People should stop putting the lights near the beach now. It kills the loggerhead turtles each year and soon they will become extinct.

They are also known for being fun to watch. As you see your turtle they will be on the rock a lot, and if you see your turtle just sitting on the rock then that’s called “basking”. As the turtles get used to their tank, they will slide on the rock you put into your tank.

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.

The Graptemys caglei, also known as the Cagle’s Map Turtle, is an endangered turtle species found in San Antonio, Texas and along the Guadalupe River. It identifies easily by the pattern on its shell which resembles an aerial view topography, as well as its spiked shell edges, which are not as sharp as other map turtles of the same genus. Although the Cagle’s Map Turtle has natural predators pose a threat to the individual turtles’ lives, the predators are not a greater threat than habitat disturbances created by humans. Unfortunately, this species suffered a significant drop in population since the mid-1970 through changes in its habitat disallow support of a larger population of the turtles(van Dijk, P. P., 2011).

Rather than have one or two high dense areas of Chelonia mydas entire lagoons and bays should be protected, data shows that green turtles have high fidelity with foraging areas in their lagoons (Senko et al., 2010). Another academic journal discuss how application and enforcement of legislation both domestic and international has increased in nesting and the creation of marine protected areas, more specifically in this case in the Caribbean Costa Rica (Troëng and Rankin, 2005). Non-government organizations like world wildlife fund have taken steps with local communities to combat the illegal trade of green turtle eggs and meat on the black market (worldwildlifefund.org,

Sea turtle hatchlings are now having trouble finding their way to the sea because of all the lights from buildings that are built on the coast. They get disoriented when they are born and will wander in the wrong way away from the sea. This leads them to predators that live inland or will even cause the turtle to become dehydrated and die. Humans are also building coastal armoring that is blocking female turtles from reaching a suitable nesting habitat. This is a severe problem in Florida where they have many coastal rock elevations and sand bags. Where all this beach development is occurring thousands of sea turtles are trying to nest. Beach dredging is also having a direct effect on sea turtle's trying to nest. If the sand is too impacted or is drastically different from native beach sediment, the mother will have trouble creating the

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.
