The occurrences of wildfires date back to 420 million years ago, with the evidence of fossil charcoal. Earth’s flammability is brought about by its carbon-rich vegetation, atmospheric oxygen, widespread lightning, seasonally dry climates, and volcanic ignitions. Wildfires have affected terrestrial life throughout history, especially the evolutionary aspect of Earth’s flora(plants) and fauna(animals).
Wildfires can either be caused by natural phenomena or human activities. Dry climate, lightning, and volcanic eruptions could cause wildfires to wreak havoc on the lands. Arid regions, or those who severely lack water to the extent that plant and animal life cannot grow, are susceptible to wildfires. Most arid areas include North America, South America, Africa, Australia, and Asia, especially those near the equatorial belt. Wildfires caused by lightning, particularly dry lightning, are common in Canada, Australia, and the United States. These are produced by pyrocumulus clouds in the absence of precipitation at the surface. Hot ashes and volcanic eruptions can cause wildfires, too, especially when they contact trees and grasses. Though wildfires are a natural phenomenon, the most common reason for their occurrence is human activity. The improper disposal of flammable items such as cigarettes, the installation of power-line arcs can spark an ignition that could result in large wildfires when uncontained.
Naturally occurring wildfires have beneficial effects on the ecosystems involved. Fire helps nutrients from plant matters to return back to the soil. The heat generated from the phenomenon is necessary for the germination of specific seeds. Additionally, dead trees and early forests from a high-severity fire can create habitat conditions that are advantageous to wildlife. In fact, some ecosystems rely on naturally occurring wildfires for growth and reproduction. However, if there exists too much fire, these ecosystems would suffer – like what happened in most of the massive wildfires in history.
