(birds chirping)
- [Narrator] Shrouded in a
blanket of clouds they awaken.
Their canopies of green
glitter in the sun.
Their wildlife start to slither.
(snake hissing)
- Chirp.
(birds chirping)
- And growl.
(growling)
- And one of the planets
richest ecosystems
comes to life.
(crickets chirping)
Rainforests are the oldest
living ecosystems on the planet.
Some can trace their origins
to over 70 million years ago.
Back to a time when dinosaurs
still roamed the Earth.
While the giant reptiles have disappeared
rainforests continue to thrive
growing on every continent
except Antarctica.
Two types of rainforests are
scattered across the globe.
Temperate and tropical.
Temperate rainforests are mainly
found in the mid-latitudes.
Often near cooler, coastal,
mountainous regions.
Tropical rainforests are primarily located
in warmer climates between
the Tropic of Cancer
and the Tropic of Capricorn.

As their names imply, temperate
and tropical rainforests
are the wettest forests on earth
receiving up to about 33
feet of rain per year.
This precipitation plays a
critical roll in creating
an exceptionally lush and
biologically diverse habitat.
While rainforests only make up about 6%
of the Earth's surface area, they are home
to over half of the World's
plant and animal species.
This biodiversity creates benefits
that extend far beyond
the rainforest boundaries.
Rainforest plants produce
an assortment of food items.
In addition to ingredients useful
in everyday products and medicines.
In fact, an estimated
70% of the plants used
in cancer treatments are
only found in rainforests.
On an even larger scale, rainforests help
to stabilize the planet's climate.
It's lush, green vegetation
regulate global temperatures
by absorbing massive amounts
of radiation from the Sun.
They also absorb vast
amounts of carbon dioxide
and convert them into oxygen,
about 40% of the planet's breathable air.
Over the past few centuries,
rainforests have disappeared
at an alarming rate.
Factors such as economic
inequalities, human development,
and demand for natural
resources have fueled
the deforestation of
these rich ecosystems.
At the current rate,
rainforests, which have survived
for over 70 million years
may completely disappear
within the next century.
But through educational campaigns,
sustainable logging practices,
and cooperation with local communities,
deforestation may begin to slow down
helping to preserve rainforests
for many generations to come.
