Environmental Impacts Of Marine Biodiversity Essay

When ever you go to the beach, do you ever think about what can happen to an animal and the water when you leave a wrapper in the sand or a plastic bottle in the water? If you think about it, even a small piece of plastic can harm a fish. The fish could mistake it for food. This could potentially kill the fish. There are other things that people d that pollutes the ocean. An oil spill from a boat can get fish sick (Doc.2). Also, solid waste, plastics, glass, and foam (OI). Marine life can get trapped in any of these items (OI). There are many things we can do to prevent this, like, reducing plastic waste in stream, improve solid waste management, and increase, capture, and reuse (Doc.1). These are just a few of the many things we could do to

Overfishing is a death sentence to the world’s oceans. As technology continues to improve a great deal of fish can be caught quicker; but at what cost? The effects of overfishing can lead to the extinction of not just the animals being fished, but also the predators that rely on fish to eat. Ninety percent of the ocean’s largest animals have been wiped out due to overfishing (“Overfishing- A Global Disaster”, 2011). National Geographic cites the academic journal Science (2006) that predicts by 2048, all fisheries will collapse due to lack of ocean wildlife. Fish are not the only animal caught in the nets used by fishing vessels. Often animals such as dolphins, sharks, turtles, and seabirds are

Iconic Cape Cod Massachusetts is named after the Atlantic Cod. For centuries, this fish has provided food and trade for New Englanders. In this time, there have been several instances of overfishing by humans from the aboriginal era to colonial times but none so drastic as the present conditions of cod fisheries (Jackson, Kirby, Berger, and Bjorndal, 2001). Overfishing is a human induced occurrence where humans are fishing more than a body of water can sustain. In other words, humans are catching more adult fish preventing the existing population from growing to replenish the fish that were caught (Overfishing: A Global Disaster, n.d.). Worldwide, over 80% of the fish stocks are “fully- to over-exploited, depleted, or in a state of collapse” (Overfishing: A Global Disaster, n.d.). The results of this careless behavior has reduced the biodiversity in the Gulf of Maine and landed the Atlantic Cod on the endangered species list as being “vulnerable” (Cod, n.d.). In the neighboring region of Newfoundland, Canada, communities are already feeling the effects of overfishing. In 1992, at the beginning of the fishing season in the Grand Bank region, there were suddenly no more cod. The local economies collapsed and to this day, the region has not quite recovered (Brennan and Withgott, 2005).

Consisting of less than 1% of the world oceans, the coral reefs are ancient animals comprising of thin calcium carbonate deposits within the photic layer. Aside from its biologically diverse ecosystems, coral reefs are major source of food for millions and provides habitats and nursery areas for many marine organisms. Coral reefs also act as a physical buffer to protect the coastlines from tropical storms and erosion. In addition, many local communities rely on coral reefs to generate an income through activities such as fishing and diving. However, 75% of the coral reefs are under threat from induced impacts of humans and climate change (Burke, et al., 2011). This essay looks at the human impacts constantly being inflicted on coral reefs.

The changes needed for sustainable fishing are too big and do not fit with America’s view of the economic system. Unfortunately, without these changes, the fish population will continue to decline. So, you can see that sustainable fishing in new England is not possible. Although New England and the US cannot have sustainable fishing because of their capitalistic values, as shown throughout history their values may

Black sea bass is an important recreational and commercial species along the Atlantic coast of the U.S. The market for black sea bass is for human consumption and is primarily sold fresh or frozen. In May of this year, NOAA scientists declared the southern stock of black sea bass successfully rebuilt. The catch limit for this popular fish will more than double this fall. The rebuilding plan was required by the Magnuson-Stevens Fishery Conservation and Management Act, which requires that overfishing end immediately, that overfished stocks be rebuilt, and that stocks be subject to annual catch limits. The fish are also larger on average and are showing up in places where they haven’t

The influence of the Gulf of Mexico and the Gulfstream in Southwest Florida Waters make the temperature just right for literally hundreds of different kinds of fish. In 2011, “Florida’s recreational anglers caught roughly 121 million marine fish, 74 million of which were released.” These statistics support the notion that fishing may be one of the most loved hobbies. Since fishing efforts have been drastically increasing over the years, dozens of species are threatened with extinction and many more are experiencing serious population declines. In order to ensure that a fish’s populations will remain sustainable for future generations, anglers need regulations that will sustain the existence of a fish population.

Numerous research and scientific studies were performed on the impact of the extensive fishing along the U.S. coastline. In 1871, National Marine Fisheries Service was launched. Their mission as stated on their website, www.nefsc.noaa.gov/history/, “…devoted to the protection, study, management, and restoration of fish.” (www.nefc.noaa.gov, 2004) While the organization contributed significantly to the study of the fish and the region, the organization was completely ineffectual in any manner in protecting the fish from over fishing and unable to get passed any effective policies to control fishing. Their biocentric view allowed the organization to study fish in a manner that many groups at the time had no concern with due to the mindset of the endless capacity of the sea. The value of many of these studies while questionable at the seriousness at the time they were taken, when looking back through the history and learning from the impact that man has on our environment. In particular, this example there is good data that supports the early thoughts of a bountiful sea of fish. As the years, progress data that clearly shows the decline of various fish species as fishing continues onward. Newton, Dillingham and Choly reported (2006), “The take of Atlantic cod, crucial to the New England economy, had peaked in 1968 at 3.9 million tons; by 1992, it was down to 1.2 million tons— a

The Atlantic and Pacific Coasts fish stocks overall show little improvement, despite the management strategies that have been implemented to try to increase fish population. This is primarily due to overexploitation

According to a study done by Living Planet Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing situation is being exacerbated by non-sustainable and destructive fishing practices and unfair fisheries partnership agreements; while there are currently attempts being made at fixing these problems and their effects on overfishing, nothing has been extremely effective.

Many breeds of fish are being captured at a faster rate than they can reproduce. Some species such as orange roughy fishing became popular in New Zealand in the 1970’s. Over time, it spread to many countries around the world. In the last 20 years, there has been a decline in catch up to 75%. It is no longer common to see in grocery stores as well as restaurants. The amounts of fish that are captured and distributed around the world are alarming opposed to the rate the fish can multiply.

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

Majestic animals that live in the ocean are rapidly dying and subsequently washing up on numerous shorelines that touch the Pacific Ocean’s waters. Disposal of a variety of toxins and damaging waste finding a path into our oceans are to blame for the deaths, which are largely preventable. Sharks, sea turtles, whales, dolphins and birds are just fraction of the marine life that are suffering because they are becoming sick or are dying of starvation. Their food sources are diminishing or disappearing as the cycle of destruction continues on down to the tiny, minute plankton that are the core of the food chain in the ocean. Contamination is causing the sudden increase of marine life deaths in the Pacific Ocean. The most recent reports of dead sea animals found washed up on shorelines don’t state scientific evidence of the cause of the mysterious deaths.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

However, many fisherman are unable to catch as many fish as they used to, so they are increasingly using cyanide and dynamite in fishing, which further degrades the coral reef ecosystem.[6] This perpetuation of bad habits simply leads to the further decline of coral reefs and therefore perpetuating the problem. One solution to stopping this cycle is to educate the local community about why conservation of marine spaces that include coral reefs is important.[7] Once the local communities understand the personal stakes at risk then they will actually fight to preserve the reefs. Conserving coral reefs has many economic, social, and ecological benefits, not only for the people who live on these islands, but for people throughout the world as well.
