Overfishing

Because of rapid local urbanization, pollution, and overfishing, the Chesapeake Bay's highly diverse ecosystem is being destroyed making the estuary an unsustainable environment. The Chesapeake Bay is the largest estuary in North America, nevertheless its ecosystem is in danger due to human activity. Many toxic wastes from the nearby cities and farms drain into the Bay creating negative effects on the Chesapeake Bay's aqua life. Some examples of chemicals that have been leaked into the…

Also, I agree that people should avoid overfishing, and there should be a viable solution to this issue; however, Etzioni describes the downfalls to practicing aquaculture. When one makes an argument, one does not want to provide examples that have not produced significant, positive results. Also…

The lack of information and overfishing at some point meet each other because people don’t know how bad, garbage and chemicals, can affect the water and how limited our resources are, as for the case of overfishing. Agriculture also plays a big role in the pollution of the environment, for example, chicken farms, specifically, chicken manure and how that poultry waste can…

Dr. Sylvia Earle is an 81-year-old oceanographer. Over the years she has spent more than 7,000 hours in the ocean. During this time, she has gained an abundance of knowledge of the oceans. Her discoveries of the ocean have given us a better understanding of the oceans. She also has awakened us to the current state of the oceans. Dr. Earle is an aquanaut, an author, and was the chief of NOAA; National Oceanic and Atmospheric Administration. Dr. Earle was born in Gibbstown, New jersey in 1935.…

Deep sea mining is a fairly new issue within the scientific community only being utilized in mineral collecting for the past two decades (Theil). Although this action is fairly new, it still can have devastating effects on ecosystems, especially the seafloor. “Because of the high demand for minerals and metals for making technological items, this new way of mining has gathered a lot of attention in the last five years. Three forms of deep-sea mineral resources have been considered thus far for…

In recent years, the world’s coral reefs have suffered tremendous losses in abundance as the effect that human consumption has on the environment increases. Coral reef degradation is highly influenced by food production practices such as fishing, agriculture, and animal agriculture. These human disturbances on the environment, both direct and indirect, have had lasting effects on both coral reefs and their composing ecosystems. Coral reefs serve a crucial role in the shaping of the oceans…

inferior water quality (For the Fishes n.d., Schmidt, Kunzmann 2005). However, every fish that dies, whether they be rare or a common breed, must be re-harvested in order to fill the quota, which places extra stress on these environments and can make overfishing more of a reality than a…

They suspect that overfishing is the underlying issue of salmon stock decrease. Information regarding certain salmon species has uncovered that near extinctions of some salmon species are due to large commercial fishing vessels. In a 2012 study by DUJS, the giant Mekong Salmon Karp has seen a more than ninety percent decline its population due to overfishing DUJS (2012). This is very compelling research into this specific salmon population…

numbers in Pacific and Mediterranean waters. Scientists have mainly focused on blooms of Aurelia Aurita in Pacific waters because of their extreme impact on the fishing industry. It has been speculated by scientists that the combination of overfishing and warming waters have directly affected these blooms. Aurelia aurita is part of the phylum named Cnidaria. These simple animals have no brain, circulatory system, respiratory system, muscles, or digestive system, yet evolutionarily,…

Abstract The Nile perch was introduced to Lake Victoria, Africa in 1954 to counteract the drastic drop in native fish stocks caused by overfishing (Lowe 2000). ¨They originally comprised 80% of the total fish biomass in Lake Victoria, but have now decreased to less than 1% offish catches from the Kenyan waters of the lake¨ (Lowe 2000). A 2003 study in the journal Nature examined algae records from the bottom of Lake Tanganyika and found that over the last century, warming waters have driven down…
