The Rain Forest

By:

Zach Santilli, Vince Char, Alex Savchuk, and Owen Schmidt

Geological Features

• In equatorial and sub equatorial regions

• Relatively constant rainfall

• Rain forests receive at least 200cm of rain annually, but some can receive up to 600cm of rain

• Lots of trees, lakes, grassland, and waterfalls

Temperature

• The temperature is any where from 20°C to 33°C

• The average temperature is 25°C

Types of Plants

• Maidenhair Fern

• Broad leaf shrubs

• Dwarf palms

• Bromeliads

• Parrot Flowers

• Philodendron

• Passion Flowers

• Evergreen Trees

Types of Animals

• Orangutan• Gorilla• Boa Constrictor• Caiman• Red Eyed Tree Frog• Poison Dart Frog• Toucan• Quetzal

Human Impact

• Cutting down rain forests for resources and to build roads

• Destroying animals habitats when the trees (their homes) are cut down

• Rainforests used to cover 16% of the Earth’s surface but now only cover 6%

• 37 plant, animal and insect species go extinct every day due to deforestation. That is 50,000 species a year

Commercial Value

• Medical– By 1980 sales of rainforest plant-based drugs in

the United States got to $4.5 billion annually– It is estimated that there are at least 330 new

drugs that can still be found in the rainforest with a value of $3 billion to $4 billion to a pharmacy and $147 billion to the world

Commercial Value (cont.)

• Land Profits– Rainforest converted to cattle operations

(farms) are worth $60 per acre– Timber harvest (choppin trees) will give the

owner $400 per acre– When an owner harvests sustainable and

renewable resources the land can offer $2,400 an acre
