Population growth

  1. 1. POPULATION GROWTH ???
  2. 2. IMPACTS OF POPULATION GROWTH• Impacts of • Impacts of population population growth growth on biological on physical environment. environment. • Biological environment• Physical comprises of environment means human, biological – non living systems, flora and environment or the fauna, living creatures land, air, water, soil from moth to and minerals. midgets.
  3. 3. Impacts on physical environment Most critical resources for human life. Population Growth Utilization + Overuse + Misuse of physical resourcesIncludes impacts on fresh water, owen valleys, waste management, allocation of resources, changing of consumption pattern, rising demand for energy etc
  4. 4. Impacts on biological environment• The biological components are bound to suffer the consequences.• Natural processes have been altered seriously that have caused serious imbalances in ecosystems.• Includes impacts on destruction of habitats, water crisis, Generalization of waste, endangerment to species, health condition etc
  5. 5. Population and Sustainable Development• 5 to 7 million hectares of agricultural lands are lost to accelerating land degradation and rapid urbanization.• 2 billion hectares is degraded as a result of overgrazing and poor farming practices.• Another 16 to 20 million hectares of tropical forests and woodlands are lost each year.• Water scarcity defined as less than 1,000 cubic metres per person per year.• climate experts worry that continued increases in atmospheric concentrations of CO2 – already 28 per cent higher than pre-industrial levels .
  6. 6. Population and Sustainable Development• Develop technologies to minimize damage to natural systems & make it widely available to developing countries as well.• Sustainability in all areas of economic activity, including agriculture, industry, forestry, fisheries, transp ortation and tourism.• Successful efforts to alleviate poverty.• Education, basic health care – including family planning and reproductive health care.
  7. 7. Pollution Pollution is the introduction by maninto the environment of contaminants that contains harmful substances
  8. 8. Air pollution• Air pollution is the modification of the natural characteristics of the atmosphere by a chemical, particulate matter, or biological agent. The atmosphere is the complex , dynamic natural gaseous system that is essential to support life on planet earth. Stratosphere ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the earths ecosystem.
  9. 9. Water pollution• Water pollution is the large set of adverse effect upon water bodies such as lakes, rivers, oceans, and groundwater caused by human activities.
  10. 10. Noise pollution• Noise pollution is displeasing human or machine created sound that disrupts the activity or happiness of human or animal life.• A common form of noise pollution is from transportation, especially from motor vehicles.
  11. 11. Causes and effects of noise pollution• No one on earth can escape the sounds of noise- an unwanted, disturbing sound that causes in the eye of beholder.• Noise is the disturbance to the human environment that is escalating at such a high rate that it will become major threat to the quality of human lives.
  12. 12. Soil Pollution• Soil pollution is defined as the build-up in soils of persistent toxic compounds, chemicals, salts, radioactive materials, or disease causing agents, which have adverse effects on plant growth and animal health.
