The sea animal cannot adjust to these changes in the ocean due to global warming. Pollution is another big problem that is threatening our ocean. The ocean has become a dumping ground. These toxins are affecting the ocean in a harmful way. This is also hurting sea life.
Assignment #4: Environmental Issue The Dead Zone By: Joelle Williams The Dead Zone The Dead Zone is an area in the ocean that cannot support life. The natural ocean ecosystem of interdependent living and non-living organisms that balance and stabilize the ecological community is abolished. The dead zone is a low-oxygen area referred to as hypoxic. This means these zones of ocean are depleted of oxygen to the point that it is detrimental to the aquatic life that inhabits it. The dead zone is littered with the carcasses of dead sea animals.
Offshore reefs caused many problems at Juno beach. These reefs were never above water, and they were covered with mines and other obstacles. The mines blew up many landing craft. As more and more tanks and vehicles landed on shore, they had to dodge numerous destroyed landing
Drowning in Plastic It’s hard to imagine life without plastic. It’s everywhere: covering our food, holding our purchases, protecting our loved ones, saving patients in hospitals and floating along our waterways and oceans. The thought of living in a world surrounded by toxic chemicals and pollution is a thought which many would rather not think about. Plastics have revolutionised the world in which we live, but with dire consequences. The production of these toxic-filled substances continues to lead the human race on a path of natural destruction; with thousands of animal sea-life dying annually from plastic consumption.
This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals. It also affects the food sources of herbivores and insects. How does acid rain affect the environment? Acid rain has a hand in global warming as well which is rapidly changing climates around the world. With the climate changes many plants and animals are having to relocate or are dying because they are not fit for the changes in their surroundings.
October 9, 2012 “Great Pacific Garbage Patch” Today’s society is facing a big problem with pollution, probably when we talk about pollution you just think about air pollution. But Captain. Charles Moore of the Algalita Marine Research Foundation discovered the Great Pacific Garbage Patch. The Pacific Garbage is an endless floating waste of plastic trash, that is killing many sea animals and underwater vegetation, but Captain Moore mission is to draw attention to the growing, and choking problem of plastic debris in our seas. The Great Pacific Patch stretch for hundreds of miles across the Pacific Ocean, basically the North part is forming a floating junkyard.
To purify polluted water we may use different type of methods according to the pollutants entered in the water. Chemical disinfection of water is one of the most important methods in the process of purifying water; this method can kill lots of pathogens that exist in the polluted water by killing them. http://www.informaction.org/images/graph_ocean-pollutants.jpg Fig 1 Water is made up of two hydrogen’s and one oxygen. Most part of the earth is water that means three fourth of the earth is made up of water but the problem is most of it is not suitable for drinking. https://qed.princeton.edu/getfile.php?f=Water_Pollution_since_the_1960s.jpg Fig 2 water pollution world wide In 1854 the British scientist John Snow discovered that cholera disease was caused by the contamination of water, he also showed that chlorine can be used to disinfect contaminated water to prevent such kind of diseases.
Humans have been known for destroying coral reefs through unlawful fishing habits. Cyanide fishing has been classified as a destructive fishing practice, yet is still being used in our oceans today. The destruction of coral reefs is greatly due to the fact that many people are unaware of a number of things. Such as the what coral reefs are, the key role they play, what cyanide fishing really is as well as the negative effects the fishing will cause. Occupying less than one percent of the ocean floor, coral reefs are home to over 25% of all marine life.
The ocean dwellers are virtually helpless, and they will ultimately have to suffer the consequences that have been created mainly by humans. Over the past few years there has been a significant change in marine life. Coral reefs are becoming endangered due to high carbon dioxide levels and effects of warming. Large predators, small fish, and other organisms make their homes in coral reefs. A process called mass bleaching has also become a danger to coral reefs.
Unfortunately, humans are the most polluting species on the planet. Pollution occurs at different levels and it doesn't just impact our planet; it impacts all species, including mankind, who dwell on it. We pollute water with chemicals and waste products from factories.Water pollution has led to a decrease in the number of various aquatic animals. Several aquatic life forms are on the verge of extinction. Vehicles, trains and planes emit toxic gases, creating air pollution.
