From the movie : The Matrix
[Agent Smith]: "I'd like to share a revelation that I've had during my time here. It came to me when I tried to classify your species and I realized that you're not actually mammals.
Every mammal on this planet instinctively develops a natural equilibrium with the surrounding environment but you humans do not.
You move to an area and you multiply and multiply until every natural resource is consumed and the only way you can survive is to spread to another area.
There is another organism on this planet that follows the same pattern.
Do you know what it is?
A virus."

Notable wildfires
Saturday, November 17, 2007
* The Milford Flat Fire which burned in 2007 in Utah is statistically the largest fire burning in Utah's history. At the time, Governor Jon Huntsman, Jr. stated that it is the biggest fire burning in the world. This fire burned 363,052 acres before it was fully contained.



* The 2003 Okanagan Mountain Park Fire was started by a lightning strike near Rattlesnake Island in Okanagan Mountain Park in British Columbia, Canada, during one of the driest summers in the past decade. The final size of the firestorm was over 250 square kilometres (61,776 acres). 60 fire departments, 1,400 armed forces troops and 1,000 forest fire fighters took part in controlling the fire, but were largely helpless in stopping the disaster.

* The Yellowstone National Park Fire of 1988 burned well over 793,880 acres (321,271 ha) before the winter snows put out the flames. (See: Yellowstone fires of 1988)

* One of the largest known wild fires, was the Great Fire of 1910, that burned in Montana and Idaho.


* The Zaca Fire burned Los Padres NF, CA. It burned 240,207 acres. It is the 2nd largest recorded fire in California.

* Siege of 1987 Refers to a complex of fires in northern California and southern Oregon that burned a total of about 650,000 acres. These fires were started by a large lightning storm in late August. The storm started roughly 1600 new fires, most caused by dry lightning. Firefighting efforts continued into October, before the majority of the fires were controlled.

* McNally Fire Sequoia NF burned roughly 151,000 acres in 2002, and is the largest wildfire recorded in the forest's history.


* The 2003 Canberra bushfires infringed on the Australian capital itself. A firestorm raced through Canberra suburbs on January 18, 2003 and damaged or destroyed 431 homes.

* In 2004, approximately 6.5 million acres burned in Alaska, in the state's largest recorded fire season. Over 500,000 acres burned in the Boundary Fire north of Fairbanks.


* The 2007 Greek fires were some of the deadliest in world history, killing at least 64 people in Peloponnese and Evia.

* The 2007 Southern California wildfires, burning an estimated 500,000 acres of land (in the San Diego and Malibu areas), with almost 900,000 people evacuated from the area.

Environmental death from fires
Wednesday, November 7, 2007
Anthropogenic factors that can affect forests include logging, human-caused forest fires, acid rain, and introduced species, among other things.



There are also many natural factors that can also cause changes in forests over time including forest fires, insects, diseases, weather, competition between species, etc. In 1997, the World Resources Institute recorded that only 20% of the world's original forests remained in large intact tracts of undisturbed forest. More than 75% of these intact forests lie in three countries - the Boreal forests of Russia and Canada and the rainforest of Brazil. In 2006 this information on intact forests was updated using latest available satellite imagery.



Satellite observation of smoke plumes from wildfires revealed that the plumes could be traced intact for distances exceeding 5,000 kilometers. This observation suggests that the plumes were in the stratosphere above weather conditions that would have brought the plume back to earth.

Atmospheric models suggest that these concentrations of sooty particles could increase absorption of incoming solar radiation during winter months by as much as 15%.

The massive forest fire in Indonesia (1997/1998) released approx. 2.57 gigatonnes of Carbon Dioxide into the atmosphere (source: Nature magazine, November 2002). During 1997-1998, the total amount of Carbon Dioxide released to the atmosphere was 6 gigatonnes. Most of the Carbon Dioxide gas is released by the continuous underground smouldering fire on the peat bogs.
