Top 5 Most Powerful Rivers in the World
By Byron Harris

When you think of a river, the last thing you think about is probably how strong its water really is. You are more than likely to think about calm flowing water that brushes over stones at the bottom of the river. Whatever you think about, it's definitely not how powerful the river is.

The Rarity of Coastal Dune Lakes
By Rick L. Brown

Only 5 areas in the world are known to have Coastal Dune Lakes. That list includes: the American Northern Pacific Coast, New Zealand, Australia, Madagascar and Florida's Panhandle Gulf Coast. That alone qualifies them as a very rare phenomenon and worthy of anyone's time to seek out and explore.

I'll refer to the Florida lakes specifically due to my familiarity with them, but I believe the same facts hold true to all. "Aeolian" Lakes are formed by wind that erodes rock and redistributes the sand to create lakes. These aeolian lakes are between 2,000 and 10,000 years old. They are also fairly shallow with an average depth of 5 feet.

Nature in Outdoor Education
By Michael Muriithi

Nature as it is a great learning atmosphere. This is and should be viewed in different school of thoughts. The best way forward is not to deny any view in relation to the environment. Every discipline has in a way or the other always depended on Nature for their sustainability. The Natural environment then has a wide impact in Education.

In general, it is now becoming a prerequisite in every aspect of our lives to consider nature and environment. All major sectors of the economy are interconnected by nature and none can work without the other. Outdoor education programs of today are considerably more "environmentally conscious" or "eco-friendly" than other aspect of living. No school or college is leaving the subject of nature or environment in their syllabus. But the question as to what exactly outdoor education should be teaching students about the natural world and the human relationship with that world, remains very much up a topic of discussion.

Wilderness and outdoor education are classified into two role:

Using Tourism to Justify Conservation
By Michael Muriithi

If the use of the natural resources is denied to people because of conservation, it means a loss of earning opportunity for the community.

If conservation causes a loss of income, the local population should be somehow be compensated. Tourism may be able to provide this compensation in a variety of ways. It may create jobs as well as opportunities for the provision of various products and services. The game parks of east Africa provide a good example: a considerable land is set aside for the park, however people may compete with the animals for the land; poachers may kill the animals for food and game meat trade as well as other ornamental trade. It is only by allocating a proportion of the profits to the local people that their support in conservation can be obtained. Such local support is essential for conservation initiative sustainability.

The American Bald Eagle - Facts Everyone Should Know
By Ryan Orlancia

Many people don't know that the bald eagle has been the symbol of the United States and the nation's national bird since 1782. Sea Eagles, so common in 18th century Europe, were a common sight to America's early settlers, and it is from mistaking the two birds that the bald eagle got its name. There were no bald eagles in Europe, as the bald eagle is found only in North America. The sea eagle name lingers, and the scientific name, Haliaetus leucocephalus, actually means "sea eagle with a white head" in Greek and Latin.

Geologic History of Denali National Park
By Frank Grabowski

Denali national Park lies in the heart of a curved mountain chain about 600 miles long, the Alaska Range. In the McKinley massif area, the range is about six miles wide and is aligned generally northeast to southwest. This is the highest part of the range with many peaks over 10,000 feet high. Elsewhere in the range, the mountains are mostly between 7000 to 9000 feet high.

The Ongoing Holocene Extinction
By Joe Crubaugh

Scientists have concrete evidence that the Earth is currently undergoing the largest mass extinction in 65 million years. Over 50 species are going extinct every single day.

The Myths on Global Warming Exposed!

Climate Change – The Coming Crisis
By Jonathon Hardcastle

While many contend that there are different reasons behind the changing of our climate, few can deny that our planet is going through a period of immense changes. While some may discredit the science, global warming is one of the main hypothesis for why our planet is heating up. In this article, we'll try to explain some of the science behind global warming so that you can understand the problem more clearly.

According to numerous scientific studies, our planet's surface temperature has increased by about 1 degree Fahrenheit within the last century. Most of this change has occurred in the past two decades, prompting the question: are our lifestyles accelerating this global change? The evidence definitely seems to point in that direction.

Many scientists point to the emission of greenhouse gases as one of the leading reasons that we are undergoing this global change. Carbon dioxide, methane, and nitrous oxide are some of the main compounds that we are releasing more and more, causing something known as the ‘Greenhouse Effect'. This occurs due to the fact that these gases tend to trap heat, and when they are released into our upper atmosphere, they trap some of the heat energy that would normally be reflected by our earth's natural processes.

It's an undisputed fact that there is more greenhouse gas in our atmosphere due to humanity. Since the beginning of the industrial revolution, it is estimated that the amount of carbon dioxide in the atmosphere has increased by as much as thirty percent. While a little greenhouse gas helps to keep our planet warm, the more and more that we release, the hotter the planet is going to get. That is an important fact to consider, being that our biosphere is finely tuned to live at the temperatures at which our planet currently operates. Many forms of both plant and animal life run the risk of extinction should the temperature change be accelerated. Fossil fuels are primarily responsible for the amount of greenhouse gases that we are releasing, and to help fix the problem, we are going to need to find an alternate source of energy, and quick. Research into alternative fuels has yielded several possible options, including the use of corn in the production of ethanol, which has already had proven usage in places such as Venezuela. The most accelerated period of temperature change has occurred in the past twenty years, and it's clearly evident that we need to address this problem while we still can.

Water Scarcity - See The World React
By Michael Hanna

Drought of course is not an uncommon phenomenon. Widespread in the third world and its severe consequences appreciated across the globe, it is only now that the developed world is beginning to feel the impact of worldwide water shortages.
