18. Air pollution is actually harmful substances
in the atmosphere which damages the
environment. With the development of
industries, came along the increase in
air pollution.
19.
20. Form Causes
A cloud of smoke from
the exhaust of a vehicle
Increasing traffic
Smoke from a factory
chimney
Growing cities
Eruption of a volcano Rapid economic
development
Cigarette smoke Industrialization
Burning leaves Apathetic people
21. Effects of Air Pollution
-Health problems
-Damage to the environment
-Damage to property
-Thinning of the protective
ozone layer of the atmosphere which is leading to
climate changes
23. Some Solutions to Air
Pollutionshould / share vehicles or use public transport to go to
work
should / get a regular pollution check for our vehicles
should / walk or use bicycles to go to near places
chimneys of factories should be fitted with proper
filters to prevent smokes from coming out and effect
the atmosphere
conserve energy:switch off fans and lights when you are
going out
26. Water pollution is the contamination
of water bodies
(e.g. lakes, rivers, oceans, groundwater).
Water pollution occurs when pollutants are
discharged directly or indirectly into water bodies
without adequate treatment to remove harmful
compounds.
27.
28. Form Cause
Toxic substances dissolve in
water or gets deposited on the
bed.
City sewage
Toxic substances enter lakes,
rivers, streams, etc.
Industrial waste
Pollutants go down into the
ground.
Agricultural run-off
29. Effects of Water Pollution
Devastating to people and animals,
fish, and birds.
Unsuitable for drinking,
recreation, agriculture, and
industry.
Destroys water life.
31. Some Solutions to Water Pollution
Factories should not throw their
wastes in water bodies
People should not bath or wash
clothes in rivers or lakes
People should not take their animals
to bath in riversor lakes
35. is the degradation of Earth's land surfaces often caused
by human activities and their misuse of land resources.
It occurs when waste is not disposed properly. Health
hazard disposal of urban and industrial wastes,
exploitation of minerals, and improper use of soil by
inadequate agricultural practices are a few factors.
36. Types of waste
Household
waste
Industrial waste
Biomedical or
hospital waste
Causes
Population increases
Increased plastics
products
Changes in lifestyle
Landfills not well
equipped to protect
against contamination
37. Effects of Land PollutionOver a long period of time, landfills start to emit
landfill gases. Landfill gas is produced due to the
anaerobic conditions that organic wastes decomposed
in.
Most waste buried in landfills give rise to hazardous
and toxic liquids known as leachates. These leachates
contaminate water sources, like the ground water
below the landfills, leading to water pollution.
Besides the points mentioned above, it is also
important to note that these over-crowded dumps,
contaminated sites and careless disposal of waste also
contributes to air and water pollution, as well as, acid
rain.
38. Since direct impacts of land
pollution are air pollution
and water pollution, the key
health problems caused by
land pollution are same as
those of air pollution and
water pollution and the
additions are increased
human injuries, from
syringes, broken glass and
cans washing onto river
banks and beaches.
39. Some Solutions to Land Pollution
People should plant more trees
People should not throw rubbish in
the streets , instead they should use
litter bins
Industries should not throw their
wastes on land
42. Sound is essential to our daily lives, but noise
is not. Noise is generally used as an unwanted
sound, or sound which produces unpleasant
effects and discomfort on the ears.
43. Causes
-Road traffic
-Factories
-Loud speakers and other
loud speaking things
-Jet planes
-Cinema halls
-Household equipments
-Plumbing, boilers,
generators…
Effects
Temporary or
permanent deafness
Headaches and earaches
The physiological
manifestations are stress,
irritability and
nervousness, feeling of
fatigue and decreases
work efficiency.
44. Some Solutions to Noise Pollution
People should not use lous speakers
Factories should be made out of the
cities
There should not be more noise
making vehicles on the roads
