Essay On Endangered Sea Turtles

Argument Essay - Sea turtles are endangered

Sea turtles are ancient animals on the earth. They have lived on the earth over some 200 billion years; they saw the dinosaurs survive and they saw them die (Velasquez-Manoff, 2007). Even though sea turtle can survive for a long time, they are in trouble in the current time. They have become one species of endangered animals. This is like a big dig in their very long existence on the earth. But it is a truth we need to face. Global warming that people made has threatened sea turtles. The problem is climate change. Temperature rising causes the sea turtle to be endangered because temperature is the important key to the gender of sea turtles’ babies (Hawkes, Broderick & Godley, 2006). Higher temperature will cause the sea turtles’ babies to be female. Male turtles will be fewer and fewer. Higher temperature also causes the sea to rise. Sea rising also destroys their habitats. There are fewer habitats for their incubation. Global warming also causes an unstable climate. There are more hurricanes and they are bigger in summer. They destroy everything, including the homes of sea turtles. So we need to notice that global warming actually causes sea turtles to be in danger of extinction, and find a method to save them. Human is also a murderer, killing sea turtles; fox is also a murderer of killing sea turtles (Canberra Times, 2007). The tourists and needs for food and medicines for humans cause sea turtles to have fewer habitats and be endangered.

Humans have responsibility to find some method to save sea turtles and to stop global warming from being worse.

First, Stopping increasing carbon dioxide is the major factor to improve the global warming. The greenhouse effect is the major factor to cause the earth to be warm. Greenhouse gases that contain water vapor, carbon dioxide, methane, nitrous oxide and ozone keep the heat in the air. But there are more and more greenhouse gases in the atmosphere, especially carbon dioxide. Humans’ activities make a lot of carbon dioxide into the atmosphere, like all kinds of air pollution from cars, airplanes, and factories. The best way to reduce global warming is to cut CO2 emission. There is too much carbon dioxide in the atmosphere and it absorbs heat, which makes our earth warmer and warmer. We have to stop global warming from being worse. We should take mass transit as much as possible because cars make exhaust gas in the air. Using new clean power should be a goal for every country, because thermal power plants will produce more waste gas in the air. The government should play an important role in alleviating global warming because we need to maintain this beautiful earth for our next generation.

Next, making a new law will save the sea turtles. Humans are also murderers of killing sea turtles. Every year a lot of sea turtles are killed by commercial fishing. Humans catch sea turtles for specimens, food, and medicine. The problems are still serious because most countries don’t make a law to protect the sea turtles. We sincerely appeal to every country’s government to pay attention to these problems and to make a law in order to protect these endangered animals. We don’t want them to be in danger of extinction because of humans’ needs. If humans don’t have any demands from sea turtles, we will decrease by one factor the causes of sea turtles being endangered.

Third, we have to establish a safe reserve for sea turtles. Sea turtles have fewer and fewer habitats to live in (Velasquez-Manoff, 2007). People establish new buildings on the beautiful beaches that sea turtles live on. They destroy the beaches to make places for vacationing. Sea turtles’ homes become scenic spots for tourism. People come here in order to see what sea turtles are like and how they live on the beaches. But this action has influenced habitats of sea turtles. Sea turtles need quiet and safe habitats to live forever. Government needs to make a law and establish several beaches for sea turtles’ lives. The special reverse that is especially for sea turtles is necessary to keep sea turtles existing in this world.

Global warming actually is a big problem of the current time. Opponents claim that global warming is a natural phenomenon and it is just a big cycle of the earth’s life. They may be right, but if they are wrong, we do not have time to rescue ourselves form this serious problems. Humans must also be in danger of extinction. Scientists do many kinds of research to prove that global warming actually threatens our daily lives. We can see a lot of data that points out that climate and the situation are different from before. Larger hurricanes appear, the sea is rising, and temperature is increasing more rapidly than before. The carbon dioxide is also increasing more rapidly than in past centuries. We believe this is a serious problem on this earth. We also need to spend time and money to do research and solve this problem. Even though it is a big cycle, we just waste money and time. If we do nothing at all and it is a real serious situation that we will not have any chance to rescue our beautiful earth. Extinction of humans will be our ending.

In conclusion, sea turtles are endangered and they also need our help to save their lives because humans cause this situation. Sea turtles who are sensitive to temperature change have a crisis for their lives. Who is the next one? We think it will happen to human beings sooner or later. Saving sea turtles will also save our humans. If we can start to find some method to solve global warning problems, and make some laws to protect sea turtles’ lives, our next generation will still be able to see sea turtles and we will exist on the earth for a long time.

Are Sea Turtles Worth Saving?

In a world full of problems and full of species, it’s a question worth asking. Are there good reasons to go to the trouble of saving endangered sea turtles? Read on and see what you think.


Sea turtles demonstrate the ultimate lesson of ecology – that everything is connected.

Sea turtles are part of two vital ecosystems, beaches and marine systems. If sea turtles become extinct, both the marine and beach ecosystems will weaken. And since humans use the ocean as an important source for food and use beaches for many kinds of activities, weakness in these ecosystems would have harmful effects on humans.

  • Though sea turtles have been living and thriving in the world’s oceans for 150 million years, they are now in danger of extinction largely because of changes brought about by humans. If we alter the oceans and beaches enough to wipe out sea turtles, will those changes make it difficult for us to survive? And if we choose to do what’s necessary to save sea turtles, might we save our own future?

    • Beaches and dune systems do not get very many nutrients during the year, so very little vegetation grows on the dunes and no vegetation grows on the beach itself. This is because sand does not hold nutrients very well. Sea turtles use beaches and the lower dunes to nest and lay their eggs. Sea turtles lay around 100 eggs in a nest and lay between 3 and 7 nests during the summer nesting season. Not every nest will hatch, not every egg in a nest will hatch, and not all of the hatchlings in a nest will make it out of the nest. All the unhatched nests, eggs and trapped hatchlings are very good sources of nutrients for the dune vegetation. Even the left-over egg shells from hatched eggs provide nutrients.
    • Dune plants use the nutrients from turtle eggs to grow and become stronger. As the dune vegetation grows stronger and healthier, the health of the entire beach/dune ecosystem becomes better. Healthy vegetation and strong root systems hold the sand in the dunes and protect the beach from erosion. As the number of turtles declines, fewer eggs are laid in the beaches, providing less nutrients. If sea turtles went extinct, dune vegetation would lose a major source of nutrients and would not be healthy or strong enough to maintain the dunes, allowing beaches to wash away.
    • Sea turtles eat jellyfish, preventing the large “blooms” of jellyfish – including stinging jellyfish – that are increasingly wreaking havoc on fisheries, recreation and other maritime activities throughout the oceans.
    • Research has shown that sea turtles often act as keystone species. Sea grass beds grazed by green sea turtles are more productive than those that aren’t. Hawksbill turtles eat sponges, preventing them from out-competing slow-growing corals. Both of these grazing activities maintain species diversity and the natural balance of fragile marine ecosystems. If sea turtles go extinct, it will cause declines in all the species whose survival depends on healthy seagrass beds and coral reefs. That means that many marine species that humans harvest would be lost.
    • Sea turtles, and many species that are affected by their presence or absence, are an important attraction for marine tourism, a major source of income for many countries.

    These are some of the roles that we know sea turtles play in the essential health of ecosystems. Who knows what other roles we will discover as science reveals more about sea turtles? While humans have the ability to tinker with the “clockwork” of life, we don’t have the ability to know when it’s okay to lose a few of the working parts.

    If you disagree, try to take apart a clock and just throw away one of the pieces that doesn’t look that important. Put the clock back together and see if it still works.


Something to think about…

In the mythology of India the survival of the sea turtle insures the survival of the world. The Indian myth states that the earth rests on the back of three elephants. These elephants in turn stand on the shell of a giant sea turtle which swims in an infinite sea. It is believed that if the sea turtle disappears the world will end.
