Everglades National Park

August 18th 2010 02:53
The Everglades National Park in the U.S. state of Florida is the largest subtropical wilderness in the United States, and is visited on average by one million people each year. It has been declared an International Biosphere Reserve, a World Heritage Site, and a Wetland of International Importance.

Unlike most U.S. national parks, Everglades National Park was created to protect a fragile ecosystem instead of safeguarding a unique geographic feature. The Everglades are wetlands created by a slow-moving river. The park protects an interconnected network of marshland and forest ecosystems that are maintained by natural forces.


Thirty-six species designated as threatened or protected live in the park, including the Florida panther, the American crocodile, and the West Indian manatee. The park protects the largest U.S. wilderness area east of the Mississippi River, is the most significant breeding ground for tropical wading birds in North America, and contains the largest mangrove ecosystem in the western hemisphere. More than 350 species of birds, 300 species of fresh and saltwater fish, 40 species of mammals, and 50 species of reptiles live within Everglades National Park.

Below are pictures of flora and fauna that can only be found in the Everglades.
These were sourced from OddityCentral here.

The Worst Forms of Pollution

August 6th 2010 02:48
Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring.

The Mother Nature Network put together this sobering article on the worst forms of pollution our planet is faced with today. Read the full report here.


Worst pollution. Oil spills
Oil Spills
In the wake of the Gulf oil spill, the harmful effects of marine oil spills are obvious. Birds, fish and other marine life can be devastated from a spill, and the ecosystems often take decades to recover. The oil is ingested by some animals, allowing pollutants to enter the food chain, harming fisheries and other industries in the region. Many people don't realize that most oil pollution actually comes from land-based activity. One way or another, oil has seeped into nearly all of Earth's ecosystems.


Air pollution and smog
Urban air pollution
According to the World Health Organization, 2.4 million people die every year primarily because of air pollution. Urban areas such as Los Angeles, Mumbai, Cairo, Beijing and many of the world's most populated cities have the worst air quality. Air pollution has been strongly correlated with increased rates of asthma, and pollution from automobiles has a strong link to pneumonia-related deaths. One of the worst cases of urban air pollution happened in London in 1952, when about 8,000 people died over the course of a few months because of a single smog event.


pollutants in the atmosphere
Greenhouse gases
The most common greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide and ozone. Carbon dioxide from the burning of fossil fuels has greatly increased since the Industrial Revolution. As greenhouse gases accumulate in the atmosphere, they cause overall warming and climate change. A few of the profound effects of rapid climate change include rising sea levels, loss of biodiversity and the melting of snowpack, which could threaten the world's fresh water supply.


antibiotic pollution and the evolution of superbugs
Pharmaceutical pollution
Pharmaceutical waste is becoming one of the world's biggest pollution concerns. Millions of doses of drugs are prescribed to people annually, and even more antibiotics are given to livestock. Those chemicals eventually make their way into the water supply. There is a natural risk to human health, but the bigger fear is that the pollution will ease the evolution of superbugs — bacteria that are immune to antibiotics.


plastic waste
Plastics
Many plastics are toxic. Vinyl chloride (PVC), is a known carcinogen, and bisphenol A (BPA) can disrupt endocrine function, can cause insulin resistance and it has been linked to heart disease. Plastics biodegrade slowly, in some cases lasting for hundreds of thousands of years. Waste accumulated from excessive use of plastics has become a worldwide problem. Gigantic islands of plastic trash have been known to accumulate in the North Pacific Gyre, the most famous of which is the Great Pacific Ocean Garbage Patch.

Washed Up

July 26th 2010 02:15
Whether it be by the action of winds, tides, waves or man, all manner of items can wash up on the sea shore. Everything from marine creatures, to driftwood and other marine debris will make there way to our beaches.
These Spectacular Examples of Washed Up Photography are from a photoset at the Digital Picture Zone.

planes grounded due to ash cloud
Planes sit on the tarmac at Gatwick airport on April 15, 2010 in London, England.


The second 2010 eruption of Eyjafjallajökull volcano in Iceland on 14 April 2010 caused extensive air travel disruption. In response to fears that ash ejected by the volcano would damage aircraft engines, the controlled airspace of many countries was closed to instrument flight rules (IFR, flying on instruments only) traffic in what became the largest air traffic shut-down since World War II. This action caused millions of passengers to be stranded not only in Europe, but across the world.

The eruption occurred beneath glacial ice. The cold water from the melting ice chilled the lava quickly, causing it to fragment into very small particles of glass (silica) and ash, which were carried into the eruption plume. Due to the extremely fine nature of the ash particles and the large volume of steam produced from the glacial meltwater, an ash plume that is hazardous to aircraft was rapidly sent high into the upper atmosphere. The presence and location of the plume depended upon the state of the eruption and the winds. Due to the way air masses function, and because of the large volume of steam produced by this eruption, the plume was injected into the jet stream.

The info-graphic below sourced from LiveScience explains the science behind the ash cloud.

The ash cloud created phenomenal lightning displays, coloured sunsets red across much of Europe, and forced flight cancellations for several days leaving five million travellers stranded around the world. Below are some amazing pictures of the eruption and its effects.

kaindy lake pictures


Kaindy Lake is a 400 meter long lake in Kazakhstan that reaches depths near 30 meters in some areas. It is located 129 km ESE of the city of Almaty and is 2,000 meters above sea level. It was created by the result of an enormous limestone landslide last century. The track to Kaindy lake has many scenic views to the Saty Gorge, the Chilik River valley and the Kaindy gorge. Dried-out trunks of submerged Schrenk’s Spruce trees rise above the surface.

In summer the waters of Lake Kaindy are a welcoming mix of green and turquoise. In winter the lake freezes over. However, brave ice divers are drawn to its ghostly waters to view the rare hidden underwater forest that lies beneath.

Below are some images from one such diving expedition.

Alaska's Mount Redoubt

April 29th 2009 08:46
Mount Redoubt, or the Redoubt Volcano, is active and currently erupting in Alaska. Mount Redoubt has erupted five times since 1900: in 1902, 1922, 1966, 1989 and 2009. Beginning March 22nd this year, Mount Redoubt began a series of volcanic eruptions which have produced ash clouds up to 65,000 feet into the sky, disrupting air traffic, drifting across Cook Inlet, and depositing layers of gritty ash on Anchorage (180km to the northeast). Thanks to Boston.com, see some pictures of this year's eruptions. More can be found here.
