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…show more content…

In 2000, the salmon produced more than 1.1 million tons or 61% of the total production of salmon in the world. This trend is particularly evident in Norway, where the combination of reduced availability of wild resources and sustained increases of crops has resulted in the production of farmed Atlantic salmon is 100 times higher than the wild catch. In Canada, the decline of natural stocks of Atlantic salmon and Pacific has led to severe restrictions on the catch of wild species. In Chile, growing sustainably salmonid species has increased, reaching in 2000 27% of world production exceeding (52%) the value of exports of fishmeal and other marine products.

In Chile within the various aquatic species on which extractive activities are carried out and cropping, the mussels are second in the national harvest totals (18%), this group being represented by the species' giant mussel "(Choromytilus chorus), the "mussel" (Mytilus chilensis) and "mussel" (Aulacomya atra) (Subpesca, 2006) (Fig.1). The development of the mussel, which represents the oldest farming activity has been developed in Chile, since there are reports of field trials from 1968 (Yanez, 1974), was initiated breakdown product of the fisheries of these resources, as the near extinction of "choro shoe" and the depletion of the natural banks of the "mussel" and "mussel." The greatest success is achieved in the cultivation of "mussel" in Putemún and other

The Problems of Over Population

There are several problems that affect the world today: war, crime, pollution, and several others. Overpopulation is a serious dilemma that is growing every year, every minute, and every second. It is the root of most, if not all, of the world’s problems1. It is the greatest global crisis facing humanity in the twenty-first century. Overpopulation is the major global problem because of several reasons. Most of the problems we have today, such as ocean depletion, food shortages, water shortages, air pollution, water pollution, and global warming are the effects of overpopulation2. The more people there are, the more resources consumed and the more waste created. A child born today in the United States for…show more content…

Mankind is increasing the greenhouse gas levels by burning fossil fuels and deforesting the earth7. As the population increases, atmospheric concentrations of greenhouse gases rise rapidly which affect the ability of the outgoing energy to pass through the atmosphere, [which] effectively heats the Earth8. Another predicament is the acid rain created by air pollution, which in turn, is created by the increasing population. Acid rain’s spread and damage involves weather, soil, and the life cycles of plants and animals on the land9. Air pollution is created from the burning of fossil fuels in cars, trucks, planes, and homes. The smoke and fumes rise into the atmosphere and combine with the moisture in the air to form acid rain10. As it rains, it eats away on things they settle on and contaminates lakes, drinkable water, which affect plants and animals11. Overpopulation also causes conflict. If many people live very closely together, there is a greater chance of conflict, which results in higher crime and even sometimes war12. This is why overpopulation is the major global problem. There are several things that cause this problem to come about. A major cause is the rise of living standards as the world approaches the twenty-first century, which resulted from the industrial revolution. With the help of medicine, better doctors, better housing, and a better way of life than before, the living standards are raised, which increases life
