2. is there a need to save
The reason for this sudden global call to save earth is the destruction
that has changed the face of earth. Problems like global warming,
pollution, overuse of minerals, deforestation and natural calamities
like volcanic eruptions, tsunamis, earthquakes, etc. have caused
destruction on earth.

3. THE MAJOR CAUSES ARE AS
FOLLOWS-
POLLUTION
DEFORESTATION
GLOBAL VARMING

4. WATER
POLLUTION
AIR POLLUTION
LAND
POLLUTION

5. DISTRIBUTION OF WATER
Available for
consumption
Frozen in poles
Other

6. • Organic pollution
• Agricultural pollution
• Runoff, toxic waste
• Thermal pollution.
EUTROPHICATION.. Undue
enrichment of a lake, river etc. with
nutrients, resulting in growth of organisms and
depletion of oxygen level in water.

7. More is water pollution more is the
pressure on the environment.
Waste that come from the sewage
plant encourage the growth of algae.
Overgrowth of algae water soon
becomes algae ridden and oxygen
become depleted.

8. OUR DUTIES
1. Lesser the use of water.
2. Use less cleansers when washing.
3. Never throw rubbish into the sea or
river.

10. 1. Landfills
2. Recycling of materials
3. Education to the public
FOR A CITIZEN-
1. Reuse scrap paper and plastic bag
2. Use recycled material

11. Commercial
 Traffic Industrial
Vehicle
 Factories Nuisance
 Air conditioners
Others
 Power stations

12. Government
1. Planning
relocate stationary sources of air
pollution away from the main urban
areas
2. Legislation
Air Pollution Control Regulations
Air Quality Control Zones
3. Monitoring and detection
stations to measure the amount of
the air pollutants
4. Advice and education
Free advice
Environmental education to citizens
Air Pollution Index (API) are provided
to public
Citizen
1. Improve in engineering
2. Report polluting vehicles to the police
3. Cut down the use of electricity
4.Use mass public transport

13. What are the Causes of Deforestation?
The destruction of the forests is occurring due to various reasons,
one of the main reasons being the short term economic benefits.
Given below are some more common causes of deforestation:
Used for Urban and Construction Purposes: The cutting down of trees
for lumber that is used for building materials, furniture, and paper
products. Forests are also cleared in order to accommodate expanding
urban areas.
To Grow Crops: Forests are also cut down in order to clear land for growing
crops.
To Create Grazing Land: Forests are cut down in order create land for grazing
cattle.
Used for Fuel: Trees are cut down in developing countries to be used as
firewood or
turned into charcoal, which are used for cooking and heating purposes

14. *REFORESTATION
*LEGISLATION
*WILDLIFE SANTUARY
*INICIATIVE TO CORPORATES
*COMMERCIAL FOREST CORPRATION
*WATER MANAGEMENT

17.  Solar energy
 Warming of the Earth’s core
 CO2 levels increasing because warmer oceans release
more CO2
 In turn global warming could lead to global cooling

19. Energy in our Lives:
Energy is essential. We use it for
heat, electricity, transportation and
manufacturing. We all need it to stay
warm, to cook food and to have light in the
night. We use energy to fuel our airplanes
and cars and we use it to make things in
factories. Everything from peanut butter
to plastic bottles, from T-shirts to cell
phones takes a lot of energy to make.
Where does the worlds, energy come
from today? Over 85% of it comes
from fossil fuels like coal, oil and
natural gas. The rest comes from
many other sources like
wind, water, radioactive atoms and
the sun.

20. Are Humans Causing the Climate to
Change?
 98% of greenhouse gas emissions are natural
 2% are from man-made sources
 Warmed slightly in the last 100 years, 70% of warming
occurred prior to 1940

21.  Drive efficient vehicle
 Drive less
 Buy energy efficient appliances
 Use compact florescent light bulbs (CFL)
 Weatherize your home
 Choose renewable sources of energy

22.  Unplug unused equipments
 Turn off the lights
 Set computers to sleep when not in use
 Take control of temperature
 Use appliances efficiently
