Wildfire occurrences have increased drastically over the past decade. In 2007, 2008 and 2012 more than nine million acres got burned by wildfires and majority of devastating wildfires have occurred after the year 2000.
Recent reports from Department of Agriculture predicted that wildfire burned acres is expected to double by the year 2050 to nearly twenty million acres annually.
A study conducted in the year 2012 stated that wildfire burn season has increased by 2 ½ months compared to what it was nearly forty years ago. The study also found out that whenever the Earth experiences 1°C rise in temperature, area burned in western United States nearly quadruples.
This year nearly eight million acres of grasslands and forests got devastated by wildfires in U.S which has definitely caused increase in concern regarding wildfires.
However, instructor and research biologist, Barbara Zorn-Arnold stated that even though wildfires cause temporary problems like smoke but long-term effects on ecosystem are quite beneficial. Fires increase animal and plant diversity as nutrients get released into soil which promotes new plant growth.
These new plants absorb carbon dioxide from the atmosphere and releases oxygen. The efforts to protect ecosystems from wildfire actually put them in danger.
