diminishing rapidly due to pollution‚ overfishing and climate change. I. Pollution has greatly led to the decline in coral reefs. * Sources of pollution to coral reefs. 1. Land based pollution that runs into the sea is a major threat to coral reefs. 2. Marine debris which is made up of objects discarded by humans affects corals greatly. II. Overfishing is very common as corals provide a livelihood for humans. * ways in which overfishing occur 1. Blast fishing destroys

Vengeance did not come with this‚ but in other hands‚ overfishing has also been a problem in the environmental threat category. As the author stated‚ “...have shrunken-some drastically-as a result of overfishing or catching fish faster than they can reproduce‚”(Dignan 14). This shows that overfishing is a problem because each time people overfish‚ down in the ocean fish can’t reproduce fast enough so less fish than before are

By reducing or removing a specific species‚ overfishing changes the coral reef food web” (The Coral Reef Alliance‚ 2012). The substantial amount of undesired fish that are killed reduces reproduction and leads to another problem‚ overfishing. Laws are in place to prevent harmful fishing. However‚ they are barely enforced. Villagers slip by enforcement much easier than commercial fishermen

that both sides can benefit. In the VLR provided by Axia College of University of Phoenix it is also discussed that only 10% of the oceans big fish‚ such as tuna and sword fish remain (2007). This described by one environmentalist is due to mass overfishing of the fish in the ocean. The fish simply cannot reproduce as fast as the fishing industry is pulling them out of the water. The fisherman in the VLR agrees that the fish supplies could be running low but does not know how to fix the problem without

Man created causes are overfishing‚ vessels attacks‚ human disturbance chemical and noise pollution‚ and direct human impacts. The decline of prey can be both a man created disturbance and natural cause. Man created disturbances: • over fishing • vessel attacks • pollution (chemical‚ noise) Decline of prey • direct human impacts (pollution in the oceans and imprisonment) Natural Causes: • climate change • decline of prey Overfishing One of the main reasons

endangered because of being poached for their furs or their meat. Also‚ some cases of endangerment are because of overfishing‚ disease‚ pollution‚ and overhunting. For most of the animals that are endangered are actually on the edge of extinction. Endangerment and extinction have been a part of history since pre- historic times. In my opinion‚ I believe that we should stop poaching‚ overfishing‚ and overhunting of animals because it can cause them to become extinct. If an animal or any species becomes

Next I will talk to you about Ocean pollution. Last‚ I will talk to you about overfishing. Each brings its own unique onslaught of problems.

For example‚ the species of Crown-of-thorns Starfish have killed a large portion of the Great Barrier Reef (Happening to GBR). This starfish has few predators because humans are overfishing many of them (Crown-of-thorns Starfish). To prevent future damage‚ humans must stop overfishing so species that are destroying the reef can be destroyed. Also‚ the pollution brought by

A 2008 report commissioned by WWF warned that if global temperatures rise 3.6 degrees Fahrenheit (2 degrees Celsius) above pre-industrial averages‚ sea ice in the Southern Ocean could shrink by 10 to 15 percent. If that happens‚ ice-dependant species will lose habitat and food sources. Already‚ experts warn that overfishing of krill‚ the shrimp-like basis of the Antarctic food chain‚ could
