Do fires contribute to global warming?
As a driver of climate change, wildfires release huge quantities of greenhouse gases to the atmosphere. In British Columbia, extreme fire years in 2017 and 2018 each produced three times more greenhouse gases than all other sectors of the province combined.
How much damage is caused by forest fires?
Wildfires not only destroy property and habitat, they are extremely costly. Very large fires easily do more than $1 billion dollars in damage, according to the Insurance Services Office, which performs research for the insurance industry. Some of the historically most expensive blazes are noted below.
Are forest fires bad for the environment?
It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide—a key greenhouse gas—into the atmosphere.
How fires help forests?
Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil. Reducing this competition for nutrients allows established trees to grow stronger and healthier. Fire clears the weaker trees and debris and returns health to the forest.
Where do forest fires happen the most?

What happens to a forest after a forest fire?
The forest floor is exposed to more sunlight, allowing seedlings released by the fire to sprout and grow. After fires, the charred remnants of burned trees provide habitats for insects and small wildlife, like the black-backed woodpecker and the threatened spotted owl, which make their homes in dry, hollow bark.
