What is Global Warming?
Global warming is when Earth heats up and temperature
Greenhouse effect : Sun’s heat trapped in earth
atmosphere, has trouble leaving back Causes rise in
It is increased by change in levels of Carbon dioxide
(CO2) and other greenhouse gasses, like
Rising temperature impose threats for
Living things – Plants, Animal and Humans
Yes! Climate is changing and Mankind
actions are also responsible for it
What’s causing Global Warming?
• Air Pollution
The smoke from the vehicles and factories
gather up in the atmosphere, this later on
fall as acid rain.
It leads the skin burns and the death of
Trees and plants absorb CO2
Cutting trees, Decrease of O2
Increase of CO2
CO2 absorbs heat, resulting in
• Use of Chemical Fertilizers
Fertilizers are rich in nitrogen oxide which is even
more dangerous than carbon dioxide.
These oxides of nitrogen destroys the ozone layer
even more faster than any other greenhouse gas .
Use of pesticides and fertilizers cause emissions of
carbon dioxide, methane, nitrous oxide
• Technology usage
Electronic gadgets generate heat,
Contributing to global warming.
• Volcanic Eruptions
Dust particles and gases from
eruption stays in the atmosphere
forming a cloud
These clouds make it difficult for
the radiation from leaving the
surface of the Earth
Ways to control Global Warming
Change a Light
Replacing one regular
light bulb with a
light bulb Save 150 lb
of CO2 /year
• Drive less
Walk, bike, or take common transport more often
Save 1 lb of CO2 for every mile you don't drive!
• Reduce, Reuse, Recycle
Recycling your household waste Save 2,400
lb of CO2 /year
Use cloth shopping bags instead of getting
paper or plastic at the grocery store.
Plant a tree
A single tree will absorb
1ton of CO2 over its life
• Use the "Off" Switch
Turn off television, DVD
player, phone charger
and computer when
you're not using them
Save 1000’s pounds
of CO2 /year
• Spread the awareness
Try your best to educate people about global
Tell them how they can contribute their part by
saving energy that will be good for the environment.
