Forests are the lungs of the earth. It is the trees which absorb the carbon dioxide released by the burning of fuel by man and keeps the air fresh. The leaves use this carbon dioxide to produce food during photosynthesis, which is needed by animals. The leaves after photosynthesis release oxygen which is a by- product of photosynthesis into the atmosphere. This oxygen in the atmosphere is needed by all living organism for respiration. Without oxygen no animal or plant can survive on this earth! The roots of trees help in absorbing the water from the ground and bring it up to the leaves. The excess water is sent out through the stomata and so the water vapour is released into the atmosphere.

THE LUNGS OF
PLANET EARTH

2. WHY
FORESTS
 Forests are the lungs of the Earth!
Not only do they purify the air we breathe, forests store carbon, help
in maintaining
global climate as well as recharge our water sources.
Forests are therefore crucial for the survival of life on this earth!
Forests are home to some of the most unique plant and animal species
and support a diversity of life forms. The loss of forests has pushed
many species to the brink of extinction.
 Forests are life support systems for the rural poor. Almost 90% of
the earth’s poverty ridden communities depend on forests for food,
fibre and energy.
 Forests provide free services to all life – water, soil and oxygen!
 About 30 million acres of forests are cleared globally every year!
Almost 50% of the logging in forests is illegal. Deforestation causes
20% of all carbon pollution causing global climate change. Water
sources are drying up and tons of soil is lost due to erosion. Flash

3. FOREST : A forest (also called a wood, woodland, wold, weald, or holt) is
an area with a high density of trees.
There are many definitions of a forest, based on the various criteria. These
plant communities cover approximately 9.4 of the Earth's surface (or 30
of total land area), though they once covered (about 50 of total land area),
in many different regions and function as habitats for organisms, hydrologic
flow modulators, and soil conservers, constituting one of the most important
aspects of the Earth's biosphere.
Although a forest is classified primarily by trees a forest ecosystem is
defined intrinsically with additional species such as fungi.

4. Purify air.
Regular climate.
Bind soil.
Control and prevents flood.
Make soil fertile.
Reduces pollution.
Shelter for animals.
Place for tribes.
Provide food, wood, rubber, gum, beewax, lac, bamboo

6. THE AMAZON
“The Lungs of the Planet”
The Amazon is the biggest tropical rainforest in the
world – covering 2.5 million square miles!
How big is that? As big as the 48 mainland US states!
The Amazon is called the “lungs” because it is our
world’s biggest supply of oxygen! More than 20%
of all the oxygen is produced from this one forest!

8. Forests affect the environment in a big way. Here
are the various ways they affect the
environment:-
1.Forests are the lungs of the earth. It is the trees which
absorb the carbon dioxide released by the burning of fuel by
man and keeps the air fresh.
2.The leaves use this carbon dioxide to produce food during
photosynthesis, which is needed by animals.
3.The leaves after photosynthesis release oxygen which is a by-
product of photosynthesis into the atmosphere.
4.This oxygen in the atmosphere is needed by all living
organism for respiration. Without oxygen no animal or plant
can survive on this earth!
5.The roots of trees help in absorbing the water from the
ground and bring it up to the leaves. The excess water is sent
out through the stomata and so the water vapour is released
into the atmosphere.

9. SOME FOREST
PLANTS
NEEM
BAMBOO SEMAL
SHEESHAM
Forests are very important
to us they serve as the
green lungs of the world.
Trees grow in forests. They
are very important to us as
they take in carbon-dioxide
released by us and give
oxygen taken in by us. That
is why forests are called
green lungs of the world.eg:
neem, semak, bamboo,
sheesham.
