Amazon Rain Forest
The Amazon rain forest, which covers approximately 2.7 million square miles
(7 million sq km), is the world’s largest tropical forest.
Located mainly in Brazil, the Amazon rain forest accounts
for more than 20 percent of all the world’s tropical forests.
Known in Brazil as the selva, the rain forest is
a vast storehouse of biological diversity, filled with
plants and animals both familiar and exotic. According
to estimates, at least half of all terrestrial species
are found in tropical forests, but many of these
species have not yet been identified.
Tropical forests contain many valuable resources,
including cacao (chocolate), nuts, spices, rare hardwoods,
and plant extracts used to make medicines.
Some drugs used in treating cancer and heart disease
come from plants found only in tropical forests. But
human intervention—logging, mining, and clearing land for
crops and grazing—has put tropical forests at
great risk. In Brazil, roads cut into the rain forest
have opened the way for settlers, who clear
away the forest only to discover soil too poor in
nutrients to sustain agriculture for more than
a few years. Land usually is cleared by a method called slash-and-burn, which
contributes to global warming by releasing great amounts of carbon dioxide into
the atmosphere.

Amazon Rain Forest
The Amazon forest, which covers about 2.7 million square miles
(7 million square kilometers), is the largest rainforest in the world.
Located mainly in Brazil, the Amazon forest accounts
for over 20 percent of tropical forests around the world.
known in Brazil as the jungle, the rain forest is
a vast reservoir of biological diversity, full of
plants and animals, both familiar and exotic. according
to estimates, at least half of all terrestrial species
are found in tropical forests, but many of these
species have not been identified.
tropical forests contain many valuable resources,
including cacao (chocolate), nuts, spices, rare woods,
and plant extracts used to make medicines.
Some medicines used to treat cancer and heart disease
come from plants found only in tropical forests. But
the intervention-logging, mining and human deforestation for
crops and pasture-placed tropical forests at
great risk. in Brazil, roads cut into the rain forest
paved the way for settlers who clear
away the forest only to find very poor soil
nutrients to sustain agriculture for more than
a few years. Land is usually removed by a method called secondary burning, which
contributes to global warming by releasing large amounts of carbon dioxide to
the atmosphere .
