Recommended: The negative effects of overfishing
In the epoch of the Anthropocene, humankind is drastically changing the dynamic of life on Earth. Our oceans, in particular, face great danger. Technological advancements in fisheries is continuously increasing efficiency, making it easier to catch vast amounts of fish in short amounts of time. But, unfortunately, we are catching more than just the targeted species. As a result of technological advances, bycatch has emerged as a huge problem in fisheries around the world. We are depleting the oceans of the life that sustains us. According to the U.S. National Bycatch Report, in the United States alone, nearly two billion pounds of bycatch have been caught by the fishing industry (Karp, Desfosse & Brooke 2011). The National Marine Fisheries
In this entertaining, search into global fish hatcheries, New York Times writer Paul Greenberg investigates our historical connection with the ever changing ocean and the wild fish within it. In the beginning of the book Paul is telling his childhood fishing stories to his friends, that night Paul discovers that that four fish dominate the world’s seafood markets in which are salmon, tuna, cod, and bass. He tries to figure out why this is and the only logical answer he could come up with is that four epochal shifts caused theses wild fish population to diminish. History shows that four epochal shifts happen within fifteen years causing certain fish species populations to diminish. He discovers for each of the four fish why this happened to
In the past twenty years a large amount of bottlenose dolphin have been killed due to the tuna fishery. In the Eastern Pacific swim large schools of tuna, these shoals tend to be under herds of dolphins, for some unexplained reason. Because of this, fishermen can easily find schools of tuna. The tuna are being caught under purse seine nets, which encircles the shoals of tuna and then is pulled back on board the fishing vessel, catching both tuna and dolphin. Initially the mortality rate was 500,000 each year for dolphins alone. Although some efforts are made to encourage the dolphins to leave the net by backing down part of the net, which allows the dolphins to escape, there are still a large number of mortalities (Bryant). On the other hand, in the last few years there has been dramatic progress in stopping the fishing industries from using purse sine nets. It has been found that dolphins are in immediate danger of extinction if these fishing techniques don’t stop.
National Security Agency/Central Security Service The National Security Agency/Central Security Service (NSA/CSS) was established in November 1952 to provide a cryptologic organization for the civilian and military leaders of the United States and to provide them with timely information. The National Security Agency (NSA) coordinates, directs, and performs highly specialized activities to produce foreign intelligence information and protect United States information systems through two main missions, Signals Intelligence (SIGINT) and Information Assurance (IA). The Signals Intelligence (SIGINT) mission uses cryptologic machines to break foreign codes to find out what they know and what they are doing. The biggest accomplishment publicly known was when they broke the Japanese military code in World War II and learned that Japan had plans of invading Midway Island.
With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.
In “The Border Patrol State” Leslie Silko makes accusations of the border patrol’s mistreatment of American citizens of Mexican decent, making the argument with almost evidence. Silko, a critically acclaimed poet, sees the border patrol as a governmental assembly addicted to interrogation, torture, and the murder of those they see fit.
Majority of Latino based gangs have roots and are structured by two dominate Mexican American criminal organization. With that being said, those two organizations are known as The Mexican Mafia (La eMe) and Nuestra Familia. While many gangs are linked to these two dominate organizations, one gang known as The Fresno Bulldogs(FBD), or formerly knows as F-14(Fresno 14) created their own structure and were founded in the 1960’s in Fresno, California. Although, the gang was originated in central California the gang does not claim neither Surenos(Southern) nor Norte (Northern) affiliation. According to the article “Fresno Bulldogs”, Bulldogs are the largest Hispanic gang operating in central California, with membership ranging from 5,000-6,000.
The sole purpose of Wildlife Services predator control is to prevent commercial livestock losses from predation by wolves, coyotes, mountain lions, and other wild carnivores (NRDC, 2011). They work with state and local governments and use a combination of lethal control methods like trapping, poisoning, and gunning. There are many different types of trapping, poisoning, and gunning.
Rupert Murray’s The End of the Line focuses on the depletion of the oceans fisheries and the devastating effects it has already begun to have on ecosystems and less affluent populations. The film opens with a description of the tribulations of Newfoundland. Once possessing waters so populous with cod that one could “walk across their backs in the water,” improved technology and larger fishing vessels began to deplete the fish stocks. Despite placing a moratorium on fishing in 1992, the fisheries had already been depleted to the point of complete collapse. Similar processes are occurring around the world, as only .6% of the ocean is restricted to fishing vessels. According to the film, much of the ocean’s catch has declined by 90%; the continuation of current trends if continue, stocks will collapse by 2048.

Over the course of the history of the United States of America, the country has had struggles with its own borders and the protection of those borders. Illegal immigration is a big problem and the smuggling of drugs, weapons, and cash over our borders into our country has evolved into a bigger problem. The United States has over seven-thousand miles of border to cover each day. That is quite a bit of land, but the only problem with this is there is a lack of manpower to cover every single mile of border. The US shares its borders with Canada and Mexico. All along these borders are small communities and cities that are occupied by US citizens. This means that these cities and communities require the protection of our Homeland Security Agency.
While all of these solutions can help keep lionfish populations in check, many scientists doubt they will ever be fully eradicated (Cote et al., 2013; Edwards et al., 2014; S. Green, 2014; Morell, 2010). This fate should inspire stricter trade legislation of exotic species along with increased public awareness efforts (Cote et al., 2013). It is an effective example that not all environmental damage is reversible.
The decline in aquatic life is harmful to American fisheries. For instance about 40% of the fishing industry in the United States is based in the Gulf of Mexico, and the majority is in shrimping (“Dead Zones”). However, the hypoxic zones “...reduced economic productivity in both commercial and recreational fisheries, and both direct and indirect impact on fisheries such as direct mortality and altered migration patterns that may lead to declines in populations.” (“Dead Zones”) Therefore, the American economy will be taking a decreasing hit along with the fish populations in the Gulf.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.

Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
