Recommended: Effect of global warming on animal life
Every living species on Earth is affected by air pollution. Approximately 6 million animals (humans, fish, mammals etc.) die each year from some type of pollution related issue. Pollution effects the respiratory system, immune system, and causes DNA mutations, and within some species, has stumped growth and reproduction. Many marine animals are in danger because of the pollution that humans have created in the world. I believe that all the trash and chemicals that we dump into the world is wrong, and that animals shouldn’t have to suffer because of humans. You should care about pollution harming marine animals because marine animal’s natural habitats are destroyed, marine animals develop health threats and because the deaths of these animals effect our ecosystem as a whole.
Because of pollution, many marine animal’s habitats are

Pollution is causing the warming of the world, which in turn warms the waters of animals that depend on the cold atmosphere. According to the article, “Threats to Polar Bears,” the icy lands that polar bears have become so dependent upon have recently began forming much later in the fall and melting much earlier in the spring. This climate change means polar bears aren’t able to find the proper habitat to live and hunt in. Without a proper place to hunt, polar bears are forced to eat less and less which puts a hindrance in their growth and reproduction. The fact that the ice caps are forming much later and leaving earlier than before is extremely worrisome because polar bears, and many other animals that depend on these lands, will have to find alternate means to survive. Marine animals also have to deal with the high increase of acidity in water. According to Jennifer Bergman, an Atmospheric Space Science Engineer, coral reefs depend on calcium
For years, we have heard of the devastating effects of global warming and how the melting of the polar ice caps will cause severe climate changes. One animal that has suffered most from global warming is the polar bear. Global warming has caused the polar bear population to decrease due to the results of having to swim longer distances, loss of habitat, and lack of mates to reproduce offspring. Global warming has caused this species to become endangered and has some attention with social media. Global warming has caused much damage to the polar bear population due to the warming of their habitat.
The effects of global warming on earth's ecosystems are expected to deepen. The rise in temperature had made the life very difficult for many animal and plant species. Some common warning signs can be seen today. A recent study shows that changes due to global warming compel many animal species to migrate at a higher altitude. Some polar bears in arctic side are drowning because they have to swim longer distances to reach ice floes. In California, shoreline, sea life is moving towards north, as a result of warm water and change in
In recent decades, the global warming threat has captured the attention of the nation and the world. While the main focus began with concentrating on the effects this long-term natural crisis would have on the human population, select groups have worked to approach the topic in a manner that entails prevention in order to help other animal and plant species around the globe. One such organization is the National Oceanic and Atmospheric Administration, which has played a major role in the conservation of the polar bear species, one of the mammals most adversely affected by the recent climate changes. As more research has been conducted regarding the polar bears, scientific name Ursus Maritimus, the conclusions have been shocking. In 2008, the Department to the Interior listed the polar bear species as “threatened” under the Endangered Species Act of 1973 awarding it some protections mandated by the federal government (Wolfe). However, on January 5, 2011, Representative Donald Young proposed a bill in Congress in order to delist the polar bears as threatened, thus decreasing and even removing the conservation efforts that have been set in place over the past three years. The polar bear Species should remain listed under the Endangered Species Act because ice thickness has decreased 40 percent during the past 30 years thus reducing the polar bears’ critical environment, if current conditions continue the polar bear populations around the world may decrease by two thirds by mid century, and since the species has been protected under the Endangered Species Act the worldwide populations have experienced stabilization or growth in most circumstances.
Unfortunately, that is the polar bear (Defenders of Wildlife, 2013). The climate change endangers the species, so much so that the animals have become one of the icons that conservationists use to illustrate the threat posed by climate change (The Huffington Post, 2014). You cannot protect a species from the impacts of climate change without addressing the issue of climate change, itself (Defenders of Wildlife, 2013). Large carnivores are extreme indicators of ecosystem health (WWF, n.d.). “As the Arctic sea ice melts, the polar bears lose their primary hunting ground — not to mention their most plentiful and nutritious prey. It remains a question whether they will be able to adapt to changing conditions and survive” (The Huffington Post, 2014). A polar bear at risk is frequently a sign of something wrong somewhere in the arctic marine ecosystem! A polar bear at risk is frequently a sign of something wrong somewhere in the arctic marine ecosystem (WWF, n.d.)!
Ocean Pollution is a serious issue in today's global politics. The delicate balance of Earth's ecosystem is put in jeopardy when the ocean is not clean. Problem evolving from ocean pollution directly harm marine life and indirectly affect human health and the Earth's many valuable resources. Ocean Pollution is a Broad term that encpompasses any and all foregin matter that directly or indirectly makes its way into the ocean. This includes everything from the extreme: oil spills, Toxic Waste dumping and industrial dumping-- to the small scael: human activities and basic carelessness. Because the oceans and all other water bodies are invariably, somehow connected, and because they account for 3/4 of the Earth's surface, they are an ideal method of transportation for pollution, allowing the rapid spread of seemingly far away toxins into a river near you! It is increasingly important that we educate ourselves as to what, exactly, ocean pollution is, so that we can identify the causes at their source and take action in small and large ways, and hopefully, prevent this terrible form of pollution from getting any worse than it is today.
There are many facts proving that global warming exists. According to NASA, average temperatures have climbed 1.4 degrees around the world since 1880, much of this in recent decades (“Global Warming Fast Facts” 1). This obviously isn’t much, but it does prove that the earth is indeed getting warmer, hence “Global Warming”. And researchers say that not only is the earth getting warmer, but the rate at which it is heating up is increasing. In this century, the last two decades have been the earth’s hottest for 400 years, and possibly the warmest it has been for several millennia (“Global Warming Fast Facts” 1). This could mean many different things: one being that humans are contributing to this, or that the earth is going through a cycle. The United Nation’s Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years have been among the warmest since 1850 (“Global Warming Fast Facts” 1). But the Arctic is feeling the biggest effects. Average temperatures in Alaska, Canada, and parts of Russia have risen twice the global average, according to the multinational Arctic Climate Impact Assessment. By 2040, the Arctic may have its first ice-free summer, since ice is disappearing so rapidly (“Global Warming Fast Facts” 1). This can be bad for many of the animal inhabitants of this region, such as polar bears who ...

The shift in seasonal ice pack in the West Hudson Bay has changed polar bear behavior, reduced prey availability, lowered birth rate, and a positive effect on polar bear and human conflict. Polar bears require seals and other high fat animals for their survival in the arctic region. The decrease in ice packs also reduces prey abundance and increased bear mortality. Seasonal break up rate has increased and reduced seal availability within the Arctic region. The Lack of food has decreased female polar bear sexual reproductively as well as body weight. Finally, polar bears are encroaching onto human territory. Human safety is being threatened as bears go on land, instead of their usual habitat, to forage for food. Humans are forced to kill bears to protect themselves. Lastly, polar bear’s future is grim. Studies have predicted bears will lose a third of their habitat by 2100. Soon these polar bears will become extinct in the 6th global mass extinction. Humans must reevaluate their population output and seek ways to preserve the polar bears for future generations to
There have been negative biosphere impacts especially in the Arctic because “greenhouse gas concentrations are driving ocean systems towards conditions not seen for millions of years (Shah 5). Conditions such as sea levels are rising which cause polar caps to melt much faster. These polar caps are important to our artic species the thought of having “ice-free summers in the Artic imply loss of an entire biome” (Shah 2). For example, animals like polar bears that have adapted life on top of ice are in danger of extinction. The melting of ice caps and glaciers are causing polar bears to lose their homes. The extinction of one species can spell trouble for other life in the ecosystem. However, polar bears are not the only species in danger.
These results agree with the hypothesis that our “untouched and super-productive world” is affecting marine life ecosystems (Vannela, 2012). All of these results combined confirm the overall hypothesis that pollution is getting worse in the ocean and more marine life ecosystems are being affected, but there
By the oceans being polluted not only are animals affected humans are too. What some people don't know is that they are killing of and disturbing offspring by polluting waters. "Ocean pollution results in smaller catches of fish all over the world, either by killing fish directly, preventing them from breeding, or causing birth abnormalities. Seabirds are unable to breed and whales are poisoned. Pollution also seems to be responsible for a new disease among seals. Without even swallowed, plastic can kill seabirds, turtles, and other creatures by trapping them. People drinking water from polluted seas can become sick. Deadly infectious diseases like cholera and typhoid can break out." There are many different types of sizes of plankton everywhere in our ocean waters.
Some of the species being threatened by pollution include: dolphins, porpoises, penguins, sharks, and polar bears.
From 1987-2004 there has been a 22 percentile drop in the polar bear population. There are numerous reasons why polar bears are in tremendous danger extinction . Global warming is by far the most significant reason why polar bears are in danger but really we should be thinking who is responsible for global warming in the first place. While global warming isn’t the easiest to reverse there are other problems that can be solved very easily be solved. Polar bears are increasingly becoming endangered because of drastic changes in the air due to pollution and global warming in the arctic.
Transportation is a big issue with pollution. Vehicles create smog, catalysts for ozone, and components for acid rain. Smog contains a chemical called ozone. Ozone can seriously affect a human’s health. It reacts with the molecules in the lining of our airways. This then causes inflammation. Acid rain has many ecological effects, but none is as bad as its impact on lakes, streams, wetlands and other bodies of water. Acid rain makes waters acidic, which causes them to absorb the aluminium that goes from soil into water. When bodies of water become more acidic, the numbers and species of fish and other organisms living in the water begin to decrease. There are many examples of water pollution. Raw sewage running into water, industrial waste spills, and exhaust fumes from vehicles. A big problem with raw sewage is that Bacteria use up oxygen in the water, as they decompose the organic material in the water. The lack of oxygen kills animals and other organisms that live in the water. Many harmful chemicals are in industrial waste. These can become drinking water pollutants if not well managed. Car exhaust creates a wide range of gases and solid matter. This causes global warming, acid rain, and it harms the environment and human health. Engine noise and oil spills also cause pollution. Since most oils float, the marine creatures most affected by oil spills are animals like sea otters, and seabirds that are found on the shore or in
Pesticides , heavy metals, and hydrocarbons have been released into the aquatic environment. Pollution in the water has many different effects on fish including their reproduction rates, health of the fish, pollution makes them more sensitive to the toxins in the water, caused them to be more prone to diseases. Diseases that fish are more prone to when affected by pollution are fin/tail rot, gill diseases which includes amoebic gill disease caused by a parasitic infection in the gills, hyperplasia the enlargement of an organ or tissue that often leads to cancer, the fish also get liver damage, neoplasia, the formation of abnormal growth of tissue, ulceration, and many more.
