Wetlands |
Why are Wetlands Important?
The Role of Wetlands in an Ecosystem Wetlands prevent
flooding by holding water much like a sponge. By doing
so, wetlands help keep river levels normal and filter
and purify the surface water. Wetlands accept water
during storms and whenever water levels are high. When
water levels are low, wetlands slowly release water. |
Introduction to Wetlands
Wetlands encompass many different habitats including
ponds, marshes, swamps, and peatlands. They are areas
where land and water meet and are wet for an
ecologically significant part of the year. Wetlands may
be temporally flooded each day as with tidal marshes, or
be filled seasonally with water from melting snow. |

Rainforests |
|
What they are and where they're
found...
Tropical
rainforests are found in 85 countries around the world.
"Ninety percent of these forests are concentrated into
fifteen countries, each country containing over 10
million hectares each. |
|
Tropical Rainforest
Tropical
rainforests contain more than half of the Earth's plant
and animal species, yet cover only about 7% of the
earth's land surface. A typical forest in the United
States contains from 5 to 12 different kinds of trees,
while a typical rainforest may have over 300 different
kinds. |

Preserving the Rainforests
The world's
rainforests are currently disappearing at a rate of 6000
acres every hour (this is about 4000 football fields per
hour). When these forests are cut down, the plants and
animals that live in the forests are destroyed, and some
species are at risk of being made extinct. |
|
Rainforest Facts
We are
losing Earth's greatest biological treasures just as we
are beginning to appreciate their true value.
Rainforests once covered 14% of the earth's land
surface; now they cover a mere 6% and experts estimate
that the last remaining rainforests could be consumed in
less than 40 years. |
|
Rainforest Facts
Rainforests
cover 2% of the Earth's surface, or 6% of its land mass,
yet they house over half the plant and animal species on
Earth. They originally covered at least twice that area. |
|
Rainforest Animals
The rain
forest is home to over 50% of all the animals in the
world. There are millions of different species of
animals in the world's rain forests. |
|
Life in a Rainforest
Found here
are unique and spectacular wildlife and plants,
including rare and restricted species found nowhere else
on Earth. A rich and varied landscape boasts
Queensland's highest mountains, the continents lushest
and most diverse rainforests and breathtaking wilderness
areas. |
|
Rainforest Animals
Rainforests
are tremendously rich in animal life. Rainforests are
populated with insects (like butterflies and beetles),
arachnids (like spiders and ticks), worms, reptiles
(like snakes and lizards), amphibians (like frogs and
toads), birds (like parrots and toucans) and mammals
(like sloths and jaguars). |
|
People of the Rain Forest
We often
overlook the millions of people that live in the rain
forests. Did you know that there are about 50,000,000
tribal people living in world's rainforests? |

Past Extinctions
For every species that is alive today, perhaps a
thousand more have lived previously and become extinct.
Most of these extinctions occurred before humans
evolved, and the species are known to us only through
fossils. |

General Facts
About Anarctica
Antarctica,
fifth largest of the earth's seven continents, located almost
entirely south of latitude 66°30' south (the Antarctic
Circle), and surrounding the South Pole. It is mostly circular
in shape with a long arm - the Antarctic Peninsula - reaching
out toward South America, and with two large indentations, the
Ross and Weddell seas and their ice shelves.

An Introduction
to Antarctica
Antarctica is the
coldest, highest, driest, windiest place on Earth! Are you
wearing enough warm clothes to be here?! We hope so, because
here we go! |
|
Antarctica
Antarctica
is a continent of contradictions: volcanoes erupting from a
frozen landscape; miles of snow and ice, yet hardly any snow
falls each year; an arid land surrounded by three oceans.
|
|
Climate of the
Antarctica Region
Antarctica
is the coldest continent. The lowest temperature ever recorded
anywhere on earth, -88.3° C (-126.9° F), was on August 24,
1960, at Vostok Station. The continent is also buffeted by
heavy winds. |

Water World: What Happens as
Antarctica Melts
What would
happen to the world's coastlines if the West Antarctic Ice
Sheet melted, raising global sea levels by as much as 20 feet?
Some scientists say a collapse is inevitable, possibly even
imminent. Click on the images below to get a look at selected
coasts in the aftermath of such a melting. (Black lines
represent current coastlines.)
|
|
Ice Melt
In spring
and summer when air and water temperatures increase, the sea
ice begins to melt and floes break apart. The area of sea ice
in the Antarctic which melts away in summer is about 14
Million square kilometers large.
|
|
Wildlife of
Antarctica
No
land-based vertebrate animals inhabit Antarctica.
Invertebrates, especially mites and ticks, which can tolerate
the lower temperatures, exist in the Antarctic Peninsula but
are still considered rare. The surrounding ocean, however,
abounds in living creatures.
|
|
Seabirds
Apart from
the flightless penguins many other birds frequent the sea ice
to feed and rest upon. Some of the most common are described
here. |
