Overpopulation is becoming an urgent problem in the world we live in today. According to the World Population to 2300 report by the United Nations, the human population increased from approximately 2.5 billion to 6.1 billion from 1950 to 2000. The report predicts that the human population will reach more than ten billion by 2050 (DESA, 5). The size of our large and growing population puts pressure on our planet's limited resources. The amount of fresh water available is decreasing and is worsened by population growth. The American Association for the Advancement of Science (AAAS) states in its study Atlas of Population and the Environment that all continents are experiencing a decline in water tables. The AAAS estimates that by 2025, forty-eight countries and thirty-five percent of the world's population will experience water shortages. This water shortage problem is becoming even more serious with the deterioration of water quality caused by industrial waste and sewage pollution (AAAS, 51). A growing population is also straining the food supply. A 2001 United Nations World Population Monitoring report indicates that 790 million people in less developed countries, 8 million in industrialized countries, and 26 million in countries with economies in transition suffer from malnutrition (World Population Monitoring, 16). The report goes on to say that population growth is the main reason for the increase in agricultural demand (World Population Monitoring, 38). This demand also poses problems for marine fishermen. Fish provided about six percent of the total human diet in 1996, or about fifteen percent of all animal protein. From the 1950s to the 1960s, marine fisheries around the world increased their production thanks to the middle of paper......and the environment. 1st ed. Np: University of California, 2001. 51.
