Overpopulation is becoming an urgent problem in the world we live in today. According to the United Nations' World Population to 2300 report, the human population grew from approximately 2.5 billion to 6.1 billion between 1950 and 2000. The report predicts that the human population will grow to more than ten billion by 2050 (DESA, 5). The size of our large and growing population is putting a strain on our planet's limited resources. The amount of available fresh water is decreasing and is being exacerbated by population growth. The American Association for the Advancement of Science (AAAS) states in its study Atlas of Population & Environment that all continents are experiencing declining water tables. AAAS estimates that by 2025, forty-eight countries and thirty-five percent of the world's population will have water shortages. The problem of water scarcity becomes even more serious with the deterioration of water quality caused by industrial waste and wastewater pollution (AAAS, 51). A growing population also puts a strain on food supplies. A 2001 United Nations World Population Monitoring report states that 790 million people in least developed countries, 8 million in industrialized countries and 26 million in countries in economic transition suffer from malnutrition (World Population Monitoring, 16). The report goes on to state that population growth is the main reason for the increase in agricultural demand (World Population Monitoring, 38). This demand is also causing problems for marine fishermen. In 1996, fish provided about 6 percent of humans' total diet, or about 15 percent of all animal protein. From the 1950s to the 1960s, marine fisheries around the world increased their production to... half of paper... and the environment. 1st ed. Np: University of California, 2001. 51.
