There are millions of dolphins out in the oceans and they are declining fast because people couldn’t take another 12 steps to get to the trash cans that are all over the place in cities. Teens are the ones who mostly litter. Kamilo, an island in Hawaii is surrounded by thousands pieces of trash. They now call that place the Great Pacific Garbage Patch. It used to be a beautiful island but is now ruined by trash.
This shows that an environmental threat that blue crabs face is pollution because if about 1 million animals are dying each year because of pollution, we have a serious problem. Furthermore, another ecological hazard that this incredible animal faces is fishing and it’s equipment. According to the text, “Modern fishing methods have created some serious problems for the ocean. The populations of almost all fish species that we eat have shrunken,”(Dignan 14). This proves that another environmental threat that blue crabs faces are fishing because they may not be a type of fish, but, like most crabs, they are fished, caught and sold.
The effects of oil spills on mammals are catastrophic. When these creatures come into contact with oil, they can develop hypothermia. This is caused by oil matting their fur and making it lose its ability to hold in heat. Also, the animals lick their fur clean, but this often has lethal outcomes. This can result in lung, kidney, and liver damage, as well as death from toxins.
Luther King says in "9 Interesting Facts and Statistics about Littering", 1.9 billion tons of litter end up in the ocean. The ocean is another ecosystem made up of many diverse animals and plants. In “ 5 Ways Pollution Is Killing Animals”, Abigail Geer tells us that there are many things that can pollute the water ranging from noise, chemical and acid runoff, waste water and oils. All of these types of pollutions are affecting the marine life drastically. Abigail tells us that noise pollution is hurting animals that use sonar to get around are becoming closer to extinction.
Marine mammals such as seals are being found entangled in plastic fishnets and several drown. It is tragic that the oceans have large amounts of plastic contamination which is causing problems with marine life and beach birds. It is discovered that these animals are mistaking small plastic debris for food, Susan Casey in her article, “Our Oceans Are Turning Into Plastic…Are You?”
Lake Erie could be in a water crisis soon and here is some of the side effects. One is 500,000 people could be without drinking water. Another is people could get ear infections if they swim in the water. Also if you are in a watercraft going over the algae could clog it. “The toxic algae bloom in Lake Erie that provoked last weekend 's tap water ban in Toledo, Ohio—where nearly half a million people were told not to use water for drinking, cooking, or bathing—is a preview of similar problems to come around the world, scientists say, thanks in part to climate change.” (Jane Lee).
Sea turtles often eat plastic bags instead of jellies. This cost for turtle a life, as plastic causes a blockage within digestive system. But this is only the beginning. Spots made of plastic cover for Sunlight cannot penetrate through plastic garbage into the water, algae and plankton, which is the bottom of the food chain, may simply die out. The situation can quickly turn into a global crisis.
The main species being killed are the Bottlenose Dolphins, Spotted Dolphins, Risso’s Dolphins, False Killer Whales, and Short-Finned Pilot Whales. All of those species listed are considered threatened by IUCN-World Conservation Union. If these species were to become extinct or endangered there would be an overpopulation of fish in the oceans (Conservationists). In many ways, the Japanese businesses doing these drive hunts are causing many different problems the environment that will eventually come back to haunt the
Ocean Pollution DBQ Did you know that every year, eight million metric tons of plastic is dumped or somehow ends up in the ocean (Doc. 1)? The following sentences will talk about what people are doing to pollute the oceans and how they are making the pollution better. Humans are the biggest threat to animals in the ocean because they litter so much (OI). Sometimes, people litter without even knowing they're littering.
It is also ruining the amazing marine biodiversity that South Africa has. Pollution not only comes from industrial sector such as oil companies, but also from littering and sewage. Plastic pollution is one of the types of pollution that effect the marine environment. It is impossible to give an accurate estimation of the amount of plastic that is being polluted into the ocean. However, in 1975 the global fishing fleet alone dumped approximately 135 400 tons of plastic fishing gear and 23 600 tons of synthetic packaging materials
