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. 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. 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. 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. Pollution
Pollution is the introduction by man
into the environment of contaminants
that contains harmful substances

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. 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. 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. 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. 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.
