2. INTRODUCTION
 Environmental issues are problems with the planet’s
system (air, water, soil etc.)
 Developed as a result of human interference or
mistreatment of the planet.
 Has negative impacts on the sustainability of the
environmental quality necessary for the well being of the
organisms living in it.

3. Major Environmental Issues
 Pollution
 Global Warming
 Overpopulation
 Natural Resource
Depletion
 Waste Disposal
 Urban Sprawl
 Loss of Biodiversity
and many more.

4. Major Environmental Issues:
Pollution
 occurs when pollutants contaminate the natural
surroundings
 brings about the changes that affect our normal
lifestyles adversely.
 Takes place in different forms; air, water, soil,
radioactive, noise and heat or thermal.

5. Major Environmental Issues:
Global Warming
 Climatic changes that took place as the
result of human practices like emission of greenhouse
gases.
 Leads to rising temperatures of the oceans and earth’s
surface causing melting of polar ice caps, rise in sea
levels and also unnatural patterns of precipitation such
as flash floods, excessive snow or desertification.

6. Major Environmental Issues:
Over Population
 Refers to a condition by which the population density
enlarges to a certain limit.
 Provokes the environmental deterioration results in a
remarkable decline in the quality of life.
 Population density denotes the number of inhabitants
dwelling in a specific area.
for example: 100 inhabitants per square Kilometer.

7. Major Environmental Issues:
Natural Resource Depletion
 Materials and energy for the survival
and welfare of living beings including humans are
provided by nature are called natural resources.
 Includes fossil fuels, petroleum, natural gas etc.
 The excessive harnessing of these free gifts of nature
for humans upliftments by its consumers, considered
as Natural resource depletion.

8. Major Environmental Issues:
Waste Disposal
 The over consumption of
resources and creation of plastics
are creating a global crisis of waste disposal.
 Developed countries are notorious for producing an
excessive amount of waste or garbage and dumping
their waste in the oceans and less developed countries.
 Nuclear waste disposal has tremendous health hazards
associated with it. Plastic, fast food, packaging and
cheap electronic wastes threaten the well being of
humans.

9. Major Environmental Issues:
Urban Sprawl
 Refers to migration of population from
high density urban areas to low density rural areas
 Results in spreading of city over more and more rural
land.
 Adverse effects in land degradation, increased traffic,
environmental issues and health issues.
 Growing demand of land displaces natural
environment consisting of flora and fauna instead of
being replaced.

10. Major Environmental Issues:
Loss of Biodiversity
 Human activity is leading to the
extinction of species and habitats and as a
consequence loss of biodiversity.
 Eco systems, which took millions of years to perfect,
are in danger when any species population is exploited.
 Balance of natural processes like pollination is crucial
to the survival of the eco-system and human activity
threatens the same.
 Another example is the destruction of coral reefs in the
various oceans, which supports the rich marine life.

11. An Appeal to all humans for preserving this
beautiful earth
 Afforestation i.e., planting more and more trees
 Use of biodegradable polymers
 Excessive refrigerant use must be discouraged
 Promote Successive development
 Lesser consumption of fossil fuels
 Proper Waste disposal management system
 Safer Utilization of Natural resources
