Our early ancestors relied on lightning to cause forest fires, so they could collect burning sticks and coal to help them cook food and clear land.
It wasn't just humans who benefitted. The fires helped the forests, although they destroyed trees. The diversity of animal and plant life in the forests, wetlands and prairies are partially dependent on the effects of fire. In fact, some plants cannot reproduce without it.
Fire breaks up the outside coating of seeds and stimulates germination. If all the fire is suppressed, fuel in the form of needles, brush, leaves, grass and fallen trees can build up and allow larger and sometimes uncontrollable fires to occur.
Just like when our personal and professional blind spots stay concealed, the build up of unresolved issues could result in inevitable burnout.
