  1. OVER POPULATION Danseco, Joselito Jr. E. Palomares, Cedric Mathew Environmental Science 1 – WFV-2 University of the Philippines - Diliman July 18, 2008 CLICK TO START PRESENTATION.

  2. THE PROBLEM Rapid increase in world human population poses negative environmental impact, deterioration of human living standards, and increase of poverty.

  3. DEFINITION OF RELATED TERMS • Population • Came from the Latin word “populus” meaning people. • Overpopulation • A condition in which the number of people per square unit of land area or density enlarges to a limit. • Population that is too large and too poor to be adequately supplied by scarce resources .

  4. CRITICAL ANALYSIS: FACTS AND FIGURES When birth rates are higher than death rates, there will be an increase in the population. Over the past 150 years developments in health care and sanitation around the world have led to a drop in the death rate. Thus, the human population has grown very fast.

  5. CRITICAL ANALYSIS: THE CONSEQUENCES Prolific Poverty Poverty is a condition of chronic deprivation. Poverty, is a major concern of humankind, because poverty everywhere reduces human beings to a low level of existence. Poor people lack access to enough land and income to meet basic needs. A lack of basic needs results in physical weakness and poor health. Poor health decreases the ability of the poor to work and put them deeper into poverty.

  6. CRITICAL ANALYSIS: THE CONSEQUENCES Prolific Poverty At the present growth rates, the population of economically developed countries would double in 120 years. The Third World, with over three quarters of the world's people, would double its numbers in about 33 years.

  7. CRITICAL ANALYSIS: THE CONSEQUENCES Increased Energy Demands Increasing population numbers and growing affluence—at least for some—have already resulted in rapid growth of energy consumption.

  8. CRITICAL ANALYSIS: THE CONSEQUENCES Unplanned Urbanization According to United Nations estimates, the urban population in Asia will nearly double in the next 30 years. By 2030, more than half of Asia’s population will live in cities—some 2.6 billion people.

  9. CRITICAL ANALYSIS: THE CONSEQUENCES Global Warming

  10. CRITICAL ANALYSIS: THE CONSEQUENCES Freshwater Scarcity and Water Pollution Water pollution is also a serious problem, mainly caused by the disposal of untreated sewage and industrial waste, nitrates from animal waste and chemical fertilizers, and the intrusion of seawater. Polluted, unsafe water causes millions of deaths every year, particularly among infants and young children.

  11. CRITICAL ANALYSIS: THE CONSEQUENCES Ruined Biodiversity and Habitat Destruction Due in part to population pressure, forests and wetlands have been cleared and drained, resulting in the loss of an estimated 70 to 90 percent of the region’s original wildlife habitat. Habitat destruction and pollution also threaten fresh-water and marine fish and coral reefs in the region.

  12. CRITICAL ANALYSIS: THE CONSEQUENCES Pressure on Land

  13. Overpopulation presents a negative effect on one’s living standards and the ecological balance of nature. Increasing number of people living in the planet causes more demand on the basic needs such as food and shelter, thus impacting their immediate environment.
