Global warming is a major problem caused by overuse of vehicles, leading to abnormal climate changes, rising sea levels, floods, loss of biodiversity and reduced snow and ice. Soil contamination occurs due to industrial activities, agriculture, waste disposal and acid rain, harming human and plant health as well as decreasing soil fertility. Mangroves stabilize shorelines, recharge groundwater, control floods and depletion of mangroves reduces biodiversity and sediment/nutrient retention.

1. GLOBAL WARMING AND
IT’S IMPACTS
GLOBAL WARMING AND IT'S
IMPACTS
Global warming is one of the
major problem in this world
This is majorly due to the
overuse of vehicles.
Global warming leads to several
problems
1.Abnormal climatic changes
2.Increasing the sea level
3.Flood
4.Depletion of biodiversity
5.Reduction of snow and ice

2. SOIL CONTAMINATION -
REASONS
Soil contamination was happening due to man made
chemicals
Our waste products are made of chemicals
THE MAIN CAUSE OF SOIL POLLUTION ARE
Industrial Activity
Agricultural Activities
Waste Disposal
Accidental oil spills
Acid Rain
THE EFFECTS OF SOIL POLLUTION
On health of humans
On growth of plants
Decrease soil fertility
Toxic Dust
Changes in soil structure

3. CANCER
•
Cancer is the abnormal
division of cells
•The division may leads to
the tumors .The tumors can
grow and interfere with
1. Digestive system
2. Circulatory system
3. Nervous
system

4. MANGROVES:NATURE’S
NURSERY
MANGROVE ;"NATURE NURSERY"
Now a days peoples trying to destruct
mangroves .
They don't know what are the impact
of destruction of mangroves.
The destruction of mangroves may
leads to
1. Prevents shoreline stabilization
2.Reducing the level of ground water
recharge
3.Delaying the flood and flood control
4.Biodiversity depletion
5.Reducing the level of sedimentation
and nutrient retention

5. PATHOGEN-BACTERIA
•Pathogenic bacteria is a
bacteria that causes
bacterial infection
•Most of the bacteria's are
harmless
•Inter cellular bacteria are
pathogenic bacteria which
always cause disease when
they enter the human body
•most of the bacteria's will
damage immune
