2. • Environment is everything that is around us. It can be living (biotic) or
non-living (abiotic) things. It includes physical , chemical and other
natural forces. Living things live in their environment.
WHAT IS HUMAN HEALTH ?
• Health is a state of physical, mental and social well-being in which
disease and infirmity are absent
WHAT IS ENVIRONMENT ?

3. • Environment and human health are intricately related.
• A good environment is an indication of healthy human beings and a
developed nation.
• Now polluted atmosphere has become a serious threat to the very
existence of human species.
• Pollution growth and intensification of man’s activities on various fronts
like agricultural development, urbanization and industrialization all over the
world have created a hazardous environment.
• The environment is under constant interference by human bound activities.
• The effect of environment on human health are generally accounted in
the following terms :
1) The extent to which environmental conditions lead to shortening of life.
2) The extent to which environment induced disability or impairment is
found, and
3) The extent to which the biological potential of an individual is reduced.
ENVIRONMENT AND HUMAN HEALTH

4. The various environmental factors which affect human
health are :
1) Overpopulation
2) Pollution
3) Urbanization
4) Degradation of natural resources
ENVIRONMENTAL FACTORS

5. Population explosion is the
most important cause of all
environmental problems. It
leads to poverty, over
exploitation of resources and
environmental degradation.
OVER POPULATION

6. • Any change in the environment which directly or indirectly affects the welfare of
the human beings is called pollution.
• But air pollution, water pollution and solid waste pollution are of prime concern.
• Other kinds of pollution like nuclear hazards also cause problems related to the
health.
POLLUTION

7. • Various pollutants present in
the air directly affect the
different systems of the body
• These enter the human body
by inhalation or absorption
through skin or eyes.
AIR POLLUTION

8. • About 70% of the water bodies in the
India are polluted. Majority of Indian
rivers are dangerously polluted.
• The common pollutants are the industrial
effluents, municipal wastes, agro-
chemicals, oil spills etc.
• About 60% water borne diseases are
reported in India. It includes typhoid,
cholera, bacillary and amoebic dysentery,
diarrhea and jaundice.
WATER POLLUTION0

9. • Discharge of industrial sludges or dumping of
industrial and municipal wastes is the prime
cause of land pollution.
• Such wastes includes garbage, rubbish,
hospital refuse, dead animals, agricultural
wastes etc.
• Chemicals like pesticides, weedicides,
insecticides, fungicides etc. used in agriculture,
food preservation, community health services
etc.
• Most of the pesticides are mutagenic and
carcinogenic. • Mutagens can cause
chromosomal abberations and various kinds of
hereditary abnormalities.
Solid wastes

10. Hospital refuses are the source of various infectious
diseases and these act as ideal home for disease carriers or
vectors like flies, insects, bugs, rodents etc. Heavy metals
contaminated industrial effluents cause toxicities and
various health problems such as fluorosis, minamata disease
etc.

11. • Increase in urbanization adversely affects the ecological
balance. It not only causes deforestation but also increases
uncontrolled discharge of municipal wastes.
• Most Indian cities have about 40% population which leads
to deteriorating life quality and poor health services and
flourishing of communicable diseases.
• These area lack basic amenities and are disease prone. As
such the down trodden areas of the cities are the prime
source of infectious diseases.
URBANIZATION

12. 1. Loss of natural resources adversely affects the quality of
human life, e.g. deforestation results in biodiversity loss
because biodiversity is essential for maintaining the basic life
supporting process.
2. A number of medicines procured from various life forms are
essential for human health.
DEGRADATION OF NATURAL RESOURCES

13. THEN VS NOW

14. Health and Environment linkages
Initiative (HELI ) :
HELI is a global effort by WHO and UNEP to promote and facilitate
action in developing countries to reduce mental threat to human health
in support of sustainable development objectives. HELI supports a
more coherent approach to valuing the services that ecosystem provide
to human health as part of decision making processes. Activities
include :
• Projects at country level bringing together diverse government and
civil society sectors to asses and recommend integrated policies on
environment and health issues.
• Guidance on better use of impact assessment and economic valuation
to enhance environment and health decision making.
• capacity building for policy action at local ,national and regional level
through technical workshops and interactive events including policy
makers, scientists and the public.

15. 1. As such clean and green environment is the life of life.
A time to take corrective steps is still there, if taken
care of. Now a new concept of development is needed
that emphasizes the relation between human beings
and nature.
2. A sustainable development is the only solution to save
human life and health.
