On the ground, firefighters work together to stop the fire. First, one group digs a fire line. This is a long deep ditch. It is difficult for the fire to cross this line. then, while those firefighters dig, others start a backfire. They burn the dry and leaves between the wildfire and the fire line. When the wildfire comes, there is nothing for it to use as fuel. Other firefighters cut down dead trees. That way the fire cant move to other trees firefighters risk their lives to keep people safe. Their job takes hard work, and it take courage.
