Global warming is caused by industries and vehicles releasing carbon dioxide and other greenhouse gases into the atmosphere. Trees and plants normally absorb carbon dioxide and release oxygen, but deforestation reduces this effect. Increased greenhouse gases accumulate in the atmosphere and form an insulating layer around the Earth, trapping heat like a greenhouse and causing the planet to warm. This warming causes sea levels to rise, more extreme weather, and threatens human health and the environment. Preventing further deforestation and reducing greenhouse gas emissions can help mitigate the impacts of climate change.

2. GLOBAL WARMING
- gradual warming of the
atmosphere perhaps due to the
'greenhouse effect'

3. Industries release
carbon dioxide
into the atmosphere

4. All living beings on earth
breath in oxygen and breath
out carbon dioxide during
respiration.

5. Traffic emits carbon dioxide
into the atmosphere

6. Trees and vegetation absorb
carbon dioxide and release
oxygen during photosynthesis

7. Thus cleaning the air for other living
beings,
they are often called the
LUNGS OF THE EARTH

8. When we cut trees and clear vegetation.
We reduce this cleaning process, carbon
dioxide increases at the rate of half a
year. THE GREEN HOUSE EFFECT
results.

9. Pollution emits gases
Into the atmosphere
(such
as oxides of Carbon,
Nitrogen and Sulfur,
Chloroflurocarbons,
methane,etc)

10. Pollution
gases
accumulate
and
form a layer
encircling
the
earth

11. Pollution layer insulates the earth
and returns the heat from the earth

12. THE EARTH becomes warmer ,
just like a GREENHOUSE

13. The ozone layerprotects the earth by filtering the
harmful ultravioletrays from the sunlight falling
on earth.When man-made chloroflorucarbons
destroy
the Ozone
layer.More
ultraviolet
radiation will
penetrate to
the Earth and
cause human
health problems
and damage food
crops.

14. When it is destroyed more ultraviolet
rays will fall on earth
and
cause
problems
to human
health such as:
Acute sunburn,
Premature
aging of the skin
Skin cancer,
nutritional disorders
Susceptibility to infections,

16. Polar ice caps melting

24. Spread of diseases

25. More water
and
more
hurricanes

26. Increase probability and intensity
of drought and heat waves

27. Economic consequences

30. Deforestation in Iguaco South

33. An Earth
without trees?
Possible
but
unthinkable
