Forests cover one third of the
earth’s landmass, performing vital functions
and services around the world which make
our planet alive with possibilities. The
forests serve as green lungs and water
purifying systems in nature. In fact, 1.6
billion people depend on forests for their
livelihoods. They play a key role in our
battle against climate change, releasing
oxygen into the atmosphere while storing
carbon dioxide. Forests feed our rivers and
are essential to supplying the water for
nearly 50% of our largest cities. They
create and maintain soil fertility; they help
to regulate the often devastating impact of
storms, floods and fires. Forests are the
most diverse ecosystems on land, and are
home to more than half of the terrestrial
species of animals, plants and

lungs of the earth, vital to the survival of
people everywhere -- all seven billion of us.
Forests embody so much of what is good
and strong in our lives. Yet despite all of
these priceless ecological, economic, social
and health benefits, we are destroying the
very forests we need to live and breathe.
Global deforestation is growing at an
alarming rate -- every year, 13 million
hectares of forest are destroyed.
Anthropogenic factors that can affect
forests include logging, urban sprawl,
human-caused forest fires, acid
rain, invasive species, and the practice of
shifting cultivation. If forests disappear, the
amount of Carbon Dioxide in air will
increase, resulting in increase of
temperature of earth. Furthermore, it would
cause global warming as the Carbon
Dioxide gas will trap the heat radiated by
the earth, resulting in the melting of
glaciers. People who depend on forests for
their livelihoods are struggling to survive.
Many precious species face extinction....
