Coral reefs began declining when more and more large fish, turtles and seals were killed, species which in the past had frequented coral reef systems. The "reduced visits" have led to a reduced number of herbivorous fish and "added nutrients from pollution" all of which result in seaweed overgrowth and destruction of the reef (Houlder, 2003).
Methods for Addressing Over fishing
The government has encouraged many fisheries and local agents to develop strategic plans for combating the problem of deep sea over fishing. In particular much attention has been spent on an 'ecosystem' approach to fishery management which is adaptive, geographically specified and works to balance diverse objectives (Shotton, 2003). An ecosystem approach aims at "conserving the structure and function of marine ecosystems and the fishery resource" (Shotton, 2003).
Longlines can be weighted so that bait sinks faster, and hooks can be set at night, thus reducing the impacts on unintended species including birds (CSI, 2003).
Studies suggest that over fishing is impacting deep sea fishing populations and ecosystems in many negative ways. Unless firm and well thought out actions are developed to provide fishing communities with some relief, the entire marine ecosystem as a whole may change dynamically in the next decade, with unforeseen consequences.
Some ecologists have noted that "there is no place in the ocean left where there are undisturbed fish stocks... The whole ocean has been transformed" (Harder, 2003). In order to realize improvement, governments need to work together on a global level to change the way the activities of deep sea fishing are managed. One method of improvement may depend upon the creation of protected marine areas where fishing is banned, and reduced fishing permissions in other areas where the worst impacts of over fishing is evident (Harder, 2003).
Typically the goal of a fishery is to produce a 'sustainable yield' which happens when fishing stock is kept at approximately half of its natural size (Harder, 2003). At this time, fish generally tend to grow and reproduce more rapidly than in an ecosystem that is more crowded (Harder, 2003). However for most species that are impacted by over fishing, the marine biomass is decreased beyond the halfway point, so that a sustainable yield is not possible, because fish do not have the opportunity to replenish themselves adequately (Harder, 2003).
The consequences of over fishing on the environment are devastating. Over fishing impacts marine ecosystems in many ways, both directly and indirectly. Among the obvious consequences of over fishing which include the destruction or potential extinction of certain species, over fishing may also result in increased pollution and habitat destruction. Many species are also changing in composition due to over fishing practices. The long-term environmental effects of composition changes will only be determined with time.
According to research, more than 90% of large predatory fishes have been decreased to severe levels in the deep ocean, including tuna and swordfish; in addition industrialized fisheries have reduced many marine community biomasses by as much as 80% (Harder, 2003). The reduction of predatory fishes also impacts the community in many indirect ways, including the over breeding or population of certain populations as compared with others.
Over fishing has had many detrimental effects on the environment, including destruction of natural habitats, increased pollution and extinction of species, the full effects of which might not be realized for many years to come. Governments are considering establishment of marine protected areas as a first step in combating the devastating consequences of over fishing in the deep seas. Without immediate intervention it is possible that the environment as a whole will suffer severe consequences as a result of continued over fishing in the next decade.

And what about jobs, housing, and health care for all these people?" (Global Warming Is Really Happening). One of fundamental causes of this situation is the growth of technology. The Industrial Revolution not only created new forms of labor and industry but also led to an increase in the urban population. "There is a link between technology, overpopulation and the decline in the environment leads to increases in CO2 levels
Any opposing views of the issue Of course, some fisherman may protest that they need to make a living now and protest limits on fishing endangered fish species. Restaurateurs may protest they are just giving the customer what he or she desires. But they must remember the analogy of the 'dust bowl' in America -- exploit the earth now, but pay the price with a barren ocean in the future. Other water
Environmental Challenges Facing the Current Generation What are the most challenging environmental issues that will face humanity over the next 50 years? And what are the best ideas for options in the face of these challenges? What are some companies doing to mitigate (reduce, reuse, and recycle resources) the problems on a local level? These and other issues and questions will be approached in this paper. The Main Environmental Challenges While there is
For instance iron and manganese oxides particulate substances or, could in addition precipitate outside solution with carbonate or sulphide (Prosi, 1989). Sediments, thus, acts like significant course of exposure to lead for marine plants and animals. The likely or probable effect levels abbreviated as PEL may be employed in assessing the extent with which undesirable biological impacts are liable to happen due to exposure to lead in sediments.

" According to Kaur (2009) Many government and tourist agencies have adapted their organizations to offering services that are related to ecotourism activities. A high fiscal commitment is also contributed by the Ministry for its development. For instance, a total of RM1,009 billion was allocated for the development of the tourism industry during the Eighth Malaysia Plan [8 MP] (Eighth Malaysia Plan, 2001 in: Kaur, 2009). Malaysia claims a vast range
" Beyond that, another 26,000 tons of "plastic packaging material" is dumped by the fishing industry each year, Sverdrup's text maintains. Why is plastic trash so bad? First, there are over 50 million tons of plastics produced in the U.S. annually, and secondly, a good deal of that plastic is responsible "for crippling and killing tens of thousands of marine animals yearly."
