Fires are natural events and are part of the process that made our environment what it is. I recently visited Yosemite park and the giant sequoias, and it was explained that during the last 100 years or so there hadn't been any fires in the sequoias area because, to protect them, all fires were extinguished.

Then it turned out that fires are actually beneficial to sequoias reproduction, because they create an environment that is better suited to giant sequoias than the other kinds of trees. So, protecting them from fire was actually damaging their future...
