4. TOPIC :- POLLUTION
CONTENT:-
•POLLUTION
•TYPES OF POLLUTION
•CAUSES OF POLLUTION
•EFFECTS OF POLLUTION
•WAYS TO REDUCES POLLUTION

5. POLLUTION
POLLUTION IS THE INTRODUCTION OF
HARMFUL MATERIALS INTO THE
ENVIRONMENT. THESE HARMFUL MATERIALS
ARE CALLED POLLUTANTS. POLLUTANTS CAN
BE NATURAL, SUCH AS VOLCANIC ASH. THEY
CAN ALSO BE CREATED BY HUMAN ACTIVITY,
SUCH AS TRASH OR RUNOFF PRODUCED BY
FACTORIES. POLLUTANTS DAMAGE THE
QUALITY OF AIR, WATER, AND LAND.

6. TYPES OF POLLUTION
•THERE ARE FOUR TYPES OF POLLUTION :-
1.AIR POLLUTION
2.LAND POLLUTION
3.WATER POLLUTION
4.NOISE POLLUTION

7. AIR POLLUTION
•AIR POLLUTION REFERS TO ANY
PHYSICAL, CHEMICAL OR BIOLOGICAL
CHANGE IN THE AIR. IT IS THE
CONTAMINATION OF AIR BY
HARMFUL GASES, DUST AND SMOKE
WHICH AFFECTS PLANTS, ANIMALS
AND HUMANS DRASTICALLY.

8. CAUSES OF AIR POLLUTION : -
•THE BURNING OF FOSSIL FUELS
•INDUSTRIES
•VEHICLE EMISSIONS
•FARMING CHEMICALS
•DEFORESTATION

9. EFFECTS OF AIR POLLUTION:-
•GLOBAL WARMING
•ACID RAIN
•DISEASES
•OZONE LAYER DEPLETION
•CLIMATE CHANGE

10. WAYS TO REDUCE AIR POLLUTION : -
•REDUCE THE USES OF FOSSIL FUELS
•USAGE OF PUBLIC TRANSPORT AND CARPOOLING
•SWITCHING OFF THE LIGHTS WHEN THEY’RE NOT IN USE
•AVOIDING THE USE OF FIRECRACKERS
•PLANT MORE AND MORE TREES

11. LAND POLLUTION
•LAND POLLUTION REFERS TO THE
DESTRUCTION OR A DECLINE IN
QUALITY OF THE EARTH’S SURFACE
AS A RESULT OF HUMAN ACTIONS.

12. CAUSES OF LAND POLLUTION :-
•MINING
•CONSTRUCTION
•ILLEGAL DUMPING
•USES OF FERTILIZERS AND PESTICIDES
•OVER GRAZING

13. EFFECTS OF LAND POLLUTION :-
•CAN NEGATIVELY AFFECT THE QUALITY OF LIFE AND ALSO HEALTH.
•TOPSOIL GETS LOST.
•CONTAMINATION OF DRINKING WATER.
•POLLUTED SOIL, WHICH LEADS TO A LOSS OF FERTILE LAND FOR AGRICULTURE AND A REDUCTION
IN THE AVAILABILITY OF FOOD.
•CLIMATE CHANGE, WHICH CAUSES AN ONSLAUGHT OF DISASTROUS PROBLEMS, INCLUDING FLASH
FLOODS AND IRREGULAR RAINFALLS .

14. WAYS TO REDUCE LAND POLLUTION : -
•GREEN AGRICULTURE
•PROPER WASTE DISPOSAL
•USE “3 R’S” RULE(REDUCE , REUSE , RECYCLE).
•REDUCE THE USES OF FERTILIZERS AND PESTICIDES.
•AFFORESTATION AND REFORESTATION.

15. WATER POLLUTION
•WATER POLLUTION IS THE RELEASE
OF SUBSTANCES INTO BODIES OF
WATER THAT MAKES WATER UNSAFE
FOR HUMAN USE AND DISRUPTS
AQUATIC ECOSYSTEMS

16. CAUSES OF WATER POLLUTION :-
•INDUSTRIALWASTE
•MARINEDUMPING
•SEWAGEANDWASTEWATER
•OILLEAKSANDSPILLS
•USESOFFERTILIZERSANDPESTICIDES

17. EFFECTS OF WATER POLLUTION :-
•IMPACT ON DRINKING WATER
•IMPACT ON HUMAN HEALTH: DISEASE & ILLNESS
•GROUNDWATER CONTAMINATION
•EUTROPHICATION
•IT PUT IMPACT ON AQUATIC LIFE

18. WAYS TO REDUCE WATER POLLUTION
:-
•DISPOSE OF WASTE PROPERLY
•CONSERVE AS MUCH WATER AS POSSIBLE
•CONTAIN AND COMPOST YARD WASTE
•REDUCE THE USES OF FERTILIZERS AND PESTICIDES
•THE SEWAGE SHOULD NOT BE DUMP DIRECTLY INTO THE RIVER AND LAKE

19. NOISE POLLUTION
•UNWANTED OR DISTURBING
SOUND IN THE ENVIRONMENT
THAT AFFECTS THE HEALTH AND
WELL-BEING OF HUMAN AND
OTHER LIVING ORGANISMS

20. CAUSES OF NOISE POLLUTION : -
•VEHICLES
•AIRCRAFT
•INDUSTRIAL MACHINES
•LOUDSPEAKERS
•CRACKERS

21. EFFECTS OF NOISE POLLUTION :-
•STRESS RELATED ILLNESSES
• HIGH BLOOD PRESSURE
•HEARING LOSS
•HEART ATTACKS
•IRRITATION

22. WAYS TO REDUCE NOISE POLLUTION :-
•TURN OFF ELECTRONIC DEVICES OR REDUCE THE VOLUME
•CLOSE THE DOORS AND WINDOWS
•USE OF EARPLUGS
•REGULAR MAINTENANCE OF VEHICLES AND MACHINES
•USE ELECTRICAL VEHICLES
