In response to the near elimination of these species, an industry has developed to raise these species in farm communities. It was the initial belief of many that aquacultures would help offset the demand for more seafood. However, the result of fish farming has only contributed to the depletion of the fish population and to the pollution of the marine ecosystem. With only limited regulations placed upon fishing companies, they are basically able to have free range over the oceans. Because of this, there have been severe effects on many fish species.
Sometimes, less than half of the captured fish is brought back to the shore. The problem of overfishing further disrupts intricate ecosystems maintained by the already threatened coral reefs. Their destruction is synonym to a loss of habitat and refuge to numerous different marine animals. Overfishing must be the main concern of modern society because billions of people depend of fish stocks to survive.
“…hundreds of millions of people depend on fish for sustenance…” (Turan) is a quote from the article “Forget pirates; fe... ... middle of paper ... ...g form of overfishing used today. It is the action of dragging large nets across the ocean floor trying to pick up fish. This act causes the ocean floor to be disrupted and other sea creatures to be bothered. Dr. Les Watling, Professor of Zoology at the University of Hawaii stated that, “Bottom trawling is the most destructive of any actions that humans conduct in the ocean.” (Dr. Watling) Keeping a tight rein on the quantity of fish that can be caught will help to save many species. In spite of the fact that some fishermen may suffer the loss of some of their income, in the future this will help fish to become easier to catch and be more plenteous.
That´s a theory, but the problem is that when one starts removing the big species from the sea; that’s when there are less predators than prey, and the ecosystem needs to have more predators to help to keep the balance. The big fish, the bill fish, the groupers, the big things will be gone. It is happening now. If things go unchecked, we'll have a sea full of little horrible things that nobody wants to eat. We might end up with a marine junkyard dominated by plankton .
Describe your global issue in detail. my global issue is over fishing Catching too much fish for the system to support leads to an overall degradation to the system. Fishing with a high intensity to reduce the breeding stock levels to such an extent that they will no longer suppport a sufficient quantity of fish for sport or commercial harvest. deplete the stock of fish in (a body of water) by too much fishinghttp://overfishing.org/pages/what_is_overfishing.php Who/what region is involved? its an issue in North America, East China and Europe http://en.wikipedia.org/wiki/Overfishing How does this issue affect the United States?
With continued advances in technological and industrial proficiency, fishing vessels are able to fish across the globe, further exacerbating the effects of overfishing. Because the oceans are considered a shared or common resource, they inherently lack specific property rights protection and are therefore vulnerable to resource over-exploitation. As a result, fishing on much of the world’s oceans is not subject to regulation and therefore monetization of this dwindling common resource is further incentivized to the detriment of general societal welfare. The Problem Global demand for Bluefin Tuna has pushed populations of this species to “decline over 70% in the last 30 years2”. The participants, fisheries and fishermen, acting in their own self-interest for the greatest short-term gain, will eventually deplete this common resource until it is exhausted.
Although fishing supports the economy and helps feed the people within it, the risk to marine biodiversity is not worth it. Without our protection, fish species are at risk of extinction. We need healthy oceans and fishing industry so future generations have income and food. We as humans can decrease overfishing by limiting the amount of fish we eat, educating others on the effects of overfishing and finding fishing methods that limit by-catch. Our marine system needs environmental laws, policies and safeguards that state how much fishing is legal.
Seafood that has been affected by solid waste or chemical discharge is especially threatening to coastal populations because not only do they not have a choice but to consume the seafood because of economic standing, but they also do not have the means to medically treat anyone who has been affected by contaminated seafood. Conclusion In conclusion, marine pollution is a giant threat to not only marine organisms, but to the human race as well. Pollution can cause dead zones, a decline in fish catch, stunted reproduction and growth and altered breeding patterns, and a threat to coastal populations. Since the human race relies on the ocean for a large portion of its sustenance, it is imperative to mitigate any pollution that can threaten marine species.
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.
• Unsustainable Fishing/ by-catching: when fisherman use nets and heavy duty equipment for their fishing, more fish than what was needed get caught and usually are misused or discarded. In the process, sometimes other sea animals can also be caught. This is called By-catch and most of the time the fish and animals are already dead by the time they are discarded. • Consumer Needs: most fisherman work for large production industries which export and sell their fish stocks to the market for profit. With the high demand for fish such as the Blue Fin Tuna and the fear of going out of business, industries go to great measures to meet consumer needs and this can very easily lead to
