Recommended: impact of aquaculture on environment

Introduction
Global demand for food is unequivocally linked to the ever-expanding global population. With a predicted global population of 9,8 billion people by the year 2050 (United Nations, 2017), food production has to not only increase but also be environmentally and socially sustainable.
Sustainability is a key factor in the growing global demand for food. Sustainability is often described as ‘the rate of which a resource is used as to not exceed the Earth's ability to replace it’ (United Nations, 2017). That was certainly the case hundreds of years ago when the world population was only a fraction of what it is today. With great technological advances and ever-expanding population, the term ‘sustainable’ has become more complex. There are …show more content…

With a total world aquaculture production of 66,6 million tonnes of food fish in 2012, totalling a first-sale price of approximately US$137,7 billion, the aquaculture industry had grown almost thirty times since 1970. The term “food fish” includes finfishes, crustaceans, molluscs, amphibians, freshwater turtles and other aquatic animals (FAO, 2014). Almost all fish produced by the aquaculture industry ends up being used for human consumption, with by-products being used for non-food purposes. Aquaculture accounted for approximately 44,1% of the global fish production (non-food fish included) from capture fisheries and aquaculture in 2014 (FAO, 2016) and close to 50% in 2016 (Schmidt, 2016). Latest findings show a general trend in increase of aquaculture’s share in total fish production in all continents, apart from Oceania. As aquaculture’s share in the global food-fish production continues to expand, up from 31,1 percent in 2004 and 42,1 percent in 2012 (FAO, 2016), researchers predict aquaculture will produce an estimated 62% of all seafood to be consumed in 2020 (Schmidt,

  • Essay On Canada's Fishing Industry

    1832 Words  | 4 Pages

    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.

  • The Effects of Overfishing on the Restaurant Industry

    1580 Words  | 4 Pages

    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 ...

  • Argumentative Essay On Overfishing

    1623 Words  | 4 Pages

    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

    As the population of the world increases, so does the need for food. This population increase is going to put a strain on the food available as well as other resources. The resource strain created by the increased population has gathered the attention of both researchers and academics alike. Such theorists have created many ways to remedy this food strain through means of altering our foodways to be less wasteful and more sustainable, discovering new or modifying existing foodstuffs that are easier to grow and are more nutritious, and also creating new, more efficient agricultural methods and equipment. One of these ways, however, has been at work recently. There has been a global trend of discovering and consuming “superfoods,” foods that

  • Difference Between Conventional And Conventional Agriculture

    2223 Words  | 5 Pages

    As the global population continues to rise, the amount of food needed to feed the people will increase as well. Two types of agriculture systems have been the backbone for crop production for decades if not centuries: conventional and organic agriculture— both methods could not be any more different. Conventional agriculture, a method that uses synthetic chemical pesticides, technologies or additives, and practices that are unsustainable is the leading producer for our food. On the other side of spectrum, organic agriculture generally, performed in a much smaller scale, does not use synthetic chemicals and utilize methods that are environmentally sound. Most conventional

  • Agriculture and Population Growth

    862 Words  | 2 Pages

    The earth is increasing its population by 90 million people per year, and yet we still have 5.9 billion people left to feed and to give shelter (Mitchell, 1998). Along with the increase in the population, there are also more people on Earth who are living longer lives. The global population boom has coincided with the improvement of health, and of productivity, around the world. On average, the human population today lives longer, eats better, produces more, and consumes more than at any other time period in the past (Eberstadt, 1995). Agriculture feeds people, but will it be able to feed the expanding global population, especially with its exponential increase?

  • The 2030 Agenda For Sustainable Development

    Humans have become a threat to our own way of life by consuming more resources than needed, blind to the consequences that we may face in the future. As of 2016 the world population is at 7.4 billion and it is estimated to be at 11.2 billion by the year 2100. However 10 billion is the maximum population that can be sustained in terms of food security, only one of the many factors to global sustainability. Due to the fact that human consumption exceeds the amount of resources available, the United Nations “recognizes that eradicating poverty is the greatest global challenge” in A/RES/70/1. Sustainable development is not only required to fulfill the necessities of the present but to guarantee the capability for future generations to satisfy theirs.
