According to the Population Division of the United Nations, world population reached 6,500 million in 2005 and will continue growing by more than 76 million per year, United Nations estimates indicate that by 2050 there will be between 7,700 million and 10,600 million, being the most likely projection of 9,100 million inhabitants. The availability of arable land and increased efficiency in food production from land can reach their limits. The oceanographic conditions, climate and its effect on soil quality and various human uses to determine crop land will be unable to provide food for the ever growing human population. On the other hand, it is recognized, therefore, that marine and freshwater aquatic, covering over 70% of the planet's surface, are a reservoir of food substances, industrial and biomedical importance, and also a source of degradation and dilution of anthropogenic and industrial waste (Solar, 2002).
Statistics of the United Nations Organization for Food and Agriculture Organization (FAO, 2002) indicate that the production of food from the aquatic environment is close to 137 million metric tons, of which almost 31% came from farming activities. The FAO also estimates that to meet the needs of the human population of 2025, total production should increase to 165 million metric tons. This significant increase can not come from the catch of wild species without causing serious damage to marine ecosystems, lakes and rivers. Consequently, the increase in the production of seafood must necessarily come from a significant increase in the efficiency of crops. The world's most populous countries like China, India and Indonesia, or those lacking sufficient arable land areas, such as Japan, are turning mainly to aquaculture ...

... cultivation of red abalone mollusks such as oysters, mussels and mussel, found in 400 sites assessment more, excluding exempt holders of the patent only aquaculture. Despite this large number of schools working towards its cultivation, attempts have been unsuccessful, mainly due to the lack of studies regarding its development (Osorio et al., 1979), reproduction (Cancino & Becerra, 1978; Solis & Lozada, 1971), and larval settlement (Ramorino & Campos, 1983), acclimation to culture conditions (Cancino & Becerra, 1978), feeding, disease control (FIP, 1997) and basic genetic studies (Astete, 1995; Martínez-Lage et al., 2002, Martínez-Lage et al., 2005, Mena et al., 2001; Thiriot-Quievreux, 1984 Toro, 1998), which has led to seriously endanger the existence of natural banks and populations, adding to this the lack of management plans for resource extraction activities.
Earth's oceans make up over 75% of the Earth as a whole. With that being said, it is vital to understand the significance on the contents of the oceans. Since fish and marine products make up a large portion of our diet, fishing practices need to be properly managed. In this essay, overfishing will be defined, its consequences will be revealed, and plans for proper fish distribution will be executed.
One of the sectors facing the largest impact is the seafood industry. Fish products are prevalent in pet food products as well as human diets. Given such a high demand on the seafood industry,
However, Japan, one of the first countries to develop salmon hatchery program, as well as, an extensive aquaculture program receives the major credit for Japans eighty percent overall salmon production in the 1990’s. Moreover, this form of aquaculture is a principle source of fish not only in the United States, but also globally with China, now being the world’s largest producer with fish. Although, the practice of salmon aquaculture were thought to have developed via the Danish system of raising rainbow trout in freshwater
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
To fish or not to fish is a personal choice. The fact that the oceans are being overfished is a growing concern for individuals, organizations, and governments throughout the world. In this paper I want to discuss the effects of overfishing on the restaurant industry, and possible solutions to solve the problem. Fishing is an ongoing source of food for people around the world. In many countries it is a food staple in their everyday diet. In more modern societies eating fish has become a sensual experience, and not just for the wealthy. It hasn't been until population explosions in the last century that the demand for seafood has led to more effective fishing techniques and technologies. Now the demand for popular fish like the salmon, tuna, sea bass, cod and hoki, which is the key fish in McDonalds filet o' fish, is diving wild populations to dangerously low levels. The methods used to catch the amount of fish demanded by the industry do not leave sustainable populations in the wild. In an attempt to preserve the fish population, governments have set limits on the minimum size that may be harvested and how many of each may be taken. Boundaries have been set up saying which areas can be fished and which ones should be left alone. A number of smaller fisheries have gone out of business because of the limits imposed by the government. This leads to even less fish being harvested and brought to market. Therefore the amount and varieties of fish at markets are smaller and can cause shortages for wholesalers and restaurants. Some restaurants will no longer have the variety on their menus that they used to enjoy. If a restaurant thrives on its seafood menu they may be unable to cope with the shortages and will go out of business. In the ...
Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION
On the Texas coastline in 2014 alone brought in 74.7 million pounds of seafood, which is valued at more than $262.6 million. Locally harvested seafood will still be available for consumers who purchase from PJ’s Shrimp Co. for many years to come but importing more or having seafood farm-raised might help take some pressure off of our oceans and bays and allow them to reproduce and replenish the waters. However, the market price for seafood will remain high until the waters are
Future – In the near future the Debate might be still won by Overfishing but in the far future Climate change has every single possibility to be one of the major reasons not only for the depletion of fishes and other life but also every single concern that is considered to be small. The non veg population is likely to decrease due to these consequences and this might hit the non veg food industry.
Interactions between human and the ecosystem have been operating for millenniums, and are impossible to eliminate, as each depends on the other in order to survive and flourish. However, as modern technology advances, as well as the increase in the world’s population, the need for natural resources begin to rise to an alarming rate which has started to gradually destroy the ecosystem. Recently, there has been an increase of sea levels in region whilst other rain-bounty areas have begun to experience their first droughts. This phenomenon is known as climate change. Climatologists have concluded that human activity has played a major role in contributing to the changes, therefore requiring extreme measures before this phenomenon evolves into a catastrophe. In this essay, we will discuss human activities that contributed to climate change, as well as addressing possible solutions to the phenomenon.
There is 0.003% of fresh water left on this planet. We hold a growing population of 7.5 billion humans on this planet. It takes 2 years to make 10 cm of topsoil. Land degradation is becoming one of the the biggest problem to the human race because we are destroying our land and we are mistreating the use of water around the world and cities close to us which causes food deserts. Food desert is basically an area that lacks an easy access to affordable healthy fresh food.
Imagine a world where every country has a surplus of healthy, safe food. Imagine a world where this food comes from an environmental friendly source. Now imagine that all of this food is incredibly affordable for everyone. A world that is growing with more mouths to feed everyday craves the scientific advancements and achievements of agriculture in the near future. In this world, the idea for sustainable and economical agriculture is becoming recognized as the best solution for a hungry population. A fairly new system of agriculture combines aquaculture and hydroponics to form aquaponics. Aquaculture is fish farming where commercial fish are kept in containers, ponds, or tanks; hydroponics is essentially growing plants without the means of soil, using mainly water distribution (Blidariu & Grozea, 2011). These two methods combined form a sustainable and mutualistic system called aquaponics. Separately, aquaculture and hydroponics have negative implications in their systems. However, when fused together in aquaponics, the two systems solve the other’s problems (Blidariu & Grozea, 2011). Aquaponics is an innovative agriculture system that has been implemented from a need to resolve the ailments of the separate systems of aquaculture and hydroponics; this new system has effects that are beneficial to the producer, consumer, and the environment.
For centuries cultures worldwide have depended on fish, and seafood as one of the most important parts of their diet. Fish is also a much more efficient protein to harvest,and takes less freshwater to produce than other protein sources. (Savitz , J) The demand has risen throughout the years, while the global fisheries have been depleted. Corporations have effectively discovered techniques to harvest more fish, and technology and boats that can track fish to the end of the earth.
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...

The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
