So, no mating is occurring, leaving the oceans emptier each day. If this rate continues, all fish in the ocean will be almost non-existent. Already, we are experiencing a major decline in fish population: "In 2003, a scientific report estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population. "(par.6).Overfishing brings the main consequence of decrease in the fish population. People rely on fish for survival (in some countries, fish is their only source of food), and they rely on marine life for products (goods like lipstick, petroleum jelly, make-up, etc.)
The oceans are the most important food providers on Earth, with its fish being the main source of protein for nearly 1.2 billion people, but the issue of overfishing causes fishermen to return home empty-handed more often. To overfish is to “deplete the stock of fish in a body of water by excessive fishing” (Oxford Dictionaries Web). Overfishing has begun around 1950, and all fish species may collapse within the next 50 years according to some scientists (Mosbergen Web). The depletion of fish species is caused by industrial fishing boats that install on average 1.4 billion hooks annually, with a fish serving as bait at the end of each hook. Likewise, these boats may throw nets that can catch 500 tons of fish, with openings of up to 23 000 meters squared.
its an issue in North America, East China and Europe http://en.wikipedia.org/wiki/Overfishing How does this issue affect the United States? (Economic, social/humanitarian, other) severe deterioration http://oceeuropean-seas How does the number of people in the world affect this issue? Billions of people rely on fish for protein, andalso way to many people fish and go over there limit for how many fish they can catch a day .http://worldwildlife.org/threats/overfishing What are the short term, within the next year, consequences (neg. or positive) of this issue? overfishing can have a devastating impact on ocean communities as it destabilizes the food chain and destroys the natural habitats of many aquatic species.it will cause environmental change and it will cause less fish for buisnesis http://www.seaweb.org/resources/articles/writings/safina1.php http://dujs.dartmouth.edu/winter-2012/the-threats-of-overfishing-consequences-at-the-commercial-level#.Uyr8QuhX-uY What are the long term consequences (neg.
Like too much fishing, it is draining the life under the ocean. Another problem is so many tourists around beaches and oceans leads to more trash, and ships. And many years ago people hunted whales for their blubber. Also the coral is bleached. We should have a limit to how many pounds of fish each person is allowed to have, and which type of fish is more widely available, which we now do have a website for that, it tells you which fish are more available.
Since most of the population depends on fish as their protein then all of the world depends on fish if you think about it. If 30% of the earth is land than 70%is the ocean so fish are all over the world making this issue worldwide. Not much will happen in the next ye... ... middle of paper ... ...too late and all the fish species are extinct.Overfishing occurs when fish are being caught faster than they can reproduce and replace themselves so the population of fish will decrease faster , it is becoming a big issue. Because of that fish get extinct faster making our fish resource to decrease. Also many countries and nations are involved.
When humans started overfishing for the whale blubber it severely reduced and damaged the whole population of the sea life. In the fish population, many fish such as the Atlantic cod and herring were overfished to the point where they almost went extinct by the mid 1900’s. The depletion of the fish population disrupted the aquatic food chain, which became massively catastrophic by the late 20th century. More than 75% of the planet is covered by oceans, which homes much of the world’s biodiversity and a vital source of food (WWF, 2011). Today, there is no chance for any fish on the floors of all seas to escape with all the technology all of these anglers (another term for a man who fishes) are equipped with.
Overfishing has become such a threat to our oceans that, the save our oceans foundation has named it number one out of the five biggest threats to our oceans. ... ... middle of paper ... ...erfishing, to over dosing are oceans in nutrients we are killing more evolved species of marine life. With these species out of the way for competing for food and shelter, the more primitive organisms, that are not as affected by things like overfishing and too many nutrients in our ocean, are left with an abundance of resources, which is causing them to abundance in population. We have seen this across the globe and the evidence is irrefutable, and the condition of our oceans will only continue to get worse, if we don’t take action!

Scaly, Salty, Seine in the Big Old Blue Salty dihydrogen monoxide, known as the ocean contains many species of osteichthyes, chondrichthyes, and agnathans. Or in laymen’s terms, fish. These animals are threatened by the world today for one main reason, humans. We have done the undesirable, but for probable cause. We have created a market for workers to earn money by fishing, bringing in tons of fish to be sold to the public, and have gotten rid of dangerous wild animals in the oceans so people are free to swim in the ocean safely.
Soon, a fisherman whose livelihood depends on the quantity fish will have trouble providing for his family. That decreases the amount available for people to buy, negatively affecting our economy. Overfishing is another factor that negatively affects the ocean. Overfishing is defined as when one particular species is fished to the point of extinction or near extinction. One example of overfishing is evident when one looks at the Bluefin tuna.
Every year, there are about 100 million Sharks killed, ultimately for its commercial success. Their fins are used as the main ingredient for a dish so-called Shark soup. However, many are unaware of the actual importance of Sharks' existence on Earth. They do a number of things to control and balance aquatic life down below, which in return affects how we live on the surface. Sharks have existed in our world for over 400 million years, if they were to suddenly disappear for industrial purposes, much problems will be encountered throughout the world.
