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. 

Antarctica

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.
