Environmental pollution has become a common issue for the living world. The problem is increasing alarmingly since the start of the industrial revolution. Those who are looking for a clear idea about the major environmental issues can have a look on this.

2. Pollution is a negative/undesirable change
in the environment, usually the addition
of something hazardous or detrimental. When
something is added to the environment that
makes it unclean or unsafe it is called pollution

3. Harmful gases releasing into atmosphere
degrading the physical , chemical,
biological parameters of the environment
Sources of Air Pollution
Coal burning
Waste open burning
Heating and cooling mechanism
Vehicle emission
Smoke factory
Forest fire

4. Sources of Air Pollution
Coal burning

5. Waste open burning

7. Harmful pollutants releasing into
river,ocean,lakes that degrades the
physical , chemical, biological parameters
of the environment
Water Pollution occurs when the water
becomes overloaded with too much of
one thing and the aquatic organisms
cannot keep up with their cleaning
responsibilities.
Sources of water Pollution
Sewage and waste water discharge
Industrial waste discharge
Fertilizer and pesticide washed away
into water body
underground storage Leakage
Acid rain
Oil spills

8. Sewage Pollution comes
from both urban (city) and
rural (country) areas
Industrial waste discharge

9. Fertilizer and pesticide
washed away into water
body
Oil spills

10. Soil pollution is defined as the build-up in
soils of persistent toxic compounds,
chemicals, salts, radioactive materials, or
disease causing agents, which have
adverse effects on plant growth and
animal health.
Sources of land Pollution
Dumping of large quantities of solid waste
Seepage from a landfill
Septic tank seepage
Deforestation and soil erosion
Acid rain (fumes from factories mixing with
rain)
Oil and petroleum leaks from vehicles
washed off the road by the rain into the
surrounding Habitat
Solid waste seepage
Untreated municipal sludge
Demolition and construction
Non-biodegradable wastes disposal
Accumulation of animal manure
Farm residues
Indiscriminate use of fertilizers
Indiscriminate use of pesticides, insecticides
and herbicides

11. Removal of a forest where the
land is converted to a non-
forest use after it is deforested
Each year 16 million forest land
disappears
22% of the original forest around the
world remain intact today
Tropical rainforest covers 6% surface
area but contains 80%-90% of all the
species in the world
Each day 50-100 species of animals are
being lost
Impacts
Enhances green house effect
Drought occurrence
Species endangered
