What Are the Causes of the Destruction of Ecosystem? By Tamara Moffett; Updated March 13, Ecosystems consist of the animals, plants and the environmental conditions of an area. Wetlands, mangroves, rainforests and coral reefs are examples of ecosystems. Ecosystems maintain a very delicate balance.
In fact, growing coastal populations and overuse of marine resources are the main source of the problem. The pollution — linked with rising coastal populations, availability of inadequate treatment infrastructure of sewage and other waste handling facilities — is putting at risk human health and wildlife as well as livelihoods from fisheries to tourism.
Facts about marine environment — Understanding the elements of the global oceans, their biological, chemical and physical processes and the linkages amongst and between them, is critical to understanding how anthropogenic Marine ecosystem causes of degradation and affect and impact the oceans and coasts, and to developing effective management protocols to protect the oceans, coasts and their resources for future generations.
Facts about marine environment are listed: Degradation of marine environment — In general, degradation of the marine environment refers to damage caused to marine ecosystems and species and are considered as direct and indirect effects of various human activities.
Activities responsible for marine environment degradation — i Direct impacts are caused by a variety of pressures, mainly due to an increasing population, urbanization and industry and tourism development.
Classification of marine pollution — Marine pollution can be classified in various ways. It can be categorized by its essential elements what it is or where it comes from the source.
A combination of these two is often most useful because it helps us determine the likely impacts and where to focus our efforts to stop the polluting activities.
The most serious pollution impacts on the marine environment result from: Sewage in the marine environment is linked to several problems including human diseases, excessive sediments and nutrients in the water, and sometimes, toxic chemicals and marine debris.
At times, the algae rapidly consume all the oxygen in the water of a particular area, leading to fish kills. Trash originates from a wide variety of human activities, including poor trash disposal practices on land as well as from all types of boats, especially cruise ships.
Wetlands not only act as pollution filters, keeping pollutants from reaching marine waters, they are also important spawning and nursery grounds for fish.
Their destruction thus worsens the problem of declining fish populations caused by over-fishing. It can also reach the ocean indirectly, through surface water street runoff into rivers and streamsgroundwater, or the air. When we emit chemicals such as persistent organic pollutants, heavy metals such as lead, and nutrients such as nitrogen into the air, much of that ends up in the ocean through rainfall.
Functionality of marine environment protection — To protect the marine environment and ensure there is no significant further loss and degradation of marine habitats, biota and functionality by: Major pressure areas for degradation — a Major shipping corridors result in direct damage to the marine environment by anchor drag and the need for dredging activities to maintain shipping channels.
Activities at larger ports present a risk of introduction of species, accidental spills, potential contamination, and habitat destruction. Pressure from ports, other marine facilities and related infrastructure is expected to increase.
Future increases in pressure are forecast because of expansion of the oil and gas industries.
The construction of coastal housing can impact or destroy coastal ecosystems. The marine environment also affected by discharges of treated waste water to the marine environment. In addition, people need infrastructure to access and use the marine environment, such as jetties, wharves, groynes, sea walls, marinas and moorings.
Even though the managed fisheries are relatively well managed and moving toward a whole-of-ecosystem based approach, significant pressure remains from increased recreational fishing, some non-compliance and illegal fishing. Trawling is a method of fishing that has been singled out as having a high environmental impact.
Marine Ecosystem Causes of Degradation and Case Studywhat Is the Marine Ecosystem? Marine Ecosystems Are Among the Largest of Earth's Aquatic Ecosystems. It Covers Almost 70% of the Earth's Surface. They Include Oceans, Words | 9 Pages. What is the Marine Ecosystem? Marine ecosystems are among the largest of Earth's aquatic ecosystems. These critical areas, which include estuaries, swamps, marshes, and wetlands, serve as breeding grounds or nurseries for nearly all marine species. Causes of Ocean Habitat Loss Humans and Mother Nature share blame in . Marine ecological degradation is a serious concern both because of the changes in marine systems themselves, and because of potential consequences for human populations as ecosystem services historically provided by marine systems are lost (Jackson et al. ; Worm et al. ; Palumbi et al. ).
Marine environmental management — Model control measures taken by some of the developed nation to mitigate the effects are discussed below: There are many projects underway by such government departments and individual companies to map marine and coastal habitats.
The capacity for mapping the sea floor has been enhanced dramatically by improved hydro-acoustic techniques.Pollution is one of the main causes of ecosystem destruction.
Pollution can deplete resources and drive away local animal populations. Significant sources of pollution include trash, carbon emissions, oil spills and pesticides.

It Covers Almost 70% of the Earth's Surface. The marine habitat destruction and loss is where the marine environment or the ecological set up is unable to support life due to degradation. This is a process that is .
One of the main causes that contributes to the degradation of ecosystems is the deforestation due to the advance of the agriculture frontier and inappropriate forest exploitation. More lands are deforested for commercial agriculture and live-stock rearing, and due to overexploitation of forest for wood and energy.
