Factories create equipment that destroys species in the ocean. When these species are destroyed the food chain is ruined and this threatens the ocean. Over Fishing is also harming the ocean. Entire populations of fish are being killed. Over fishing occurs when there are more fish caught than fish in the ocean to sustain fish stock.
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.
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.
With the vessels having foreign aquatic life attached to the bottom of the ship and also leaking fluids into the lake while passing through. Also for these sources of pollution cause beach closing and a decrease in aquatic
Dr Carl Meyer from Hawaii Institute of Marine Biology stated that mass levels of shark culling “runs the risk of ecosystem-level cascade effects where a general lack of sharks results in boom or bust in populations of species further down the food chain”. Furthermore when nets are used to trap sharks, often animals such as dolphins, turtles, whales and dugongs become trapped in them. Turtles are one of the most endangered species as a whole and are just innocent bystanders in this war between humans and sharks. We need to be careful of not affecting other animals in this quest to reduce shark numbers in the name of nothing. Sharks can already be caught legally by commercial and recreational fishers so any cull would be largely
The Consequences of Overfishing Overfishing has been identified across the world as a prominent environmental issue. Fish and other marine animals, such as sharks, sea turtles and dolphin, are retrieved from the oceans through indiscriminate fishing practices at a rate that cannot be sustained by natural reproduction (Jackson, 2001). Systematic overfishing with bottom trawling, dredges, and drift nets depletes the ocean of innumerable species at an alarming rate and alters the ecological balance in marine environments. The actions of shortsighted commercial fishermen have brought tremendous adverse environmental and economic consequences upon the entire world. The continuation of unrestricted fishing will worsen world hunger among impoverished coastal communities, many of whom depend on the abundance of fish to feed themselves and their families, and result in ultimate environmental chaos and the extinction of thousands of In recent years, the demand for fish, a healthy food rich in omega-3 fatty acids and lean protein, has sky-rocketed.
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.
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.
It robs the soil of essential nutrients and releases aluminum in the soil, which makes it hard for trees to take up water. Trees' leaves and needles are also harmed by acids and makes trees and plants less able to withstand cold temperatures, insects, and disease. How does it affect animals? Acid rain makes waters acidic and causes them to absorb the aluminum that makes its way from soil into lakes and streams. This combination makes waters toxic to crayfish, clams, fish, and other aquatic animals.
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.
