 Wildfires can be a massively destructive force. And in a climate-primed landscape with dry soil and hot temperatures, it's one that can get out of control very quickly. But wildfires are a natural process, one that often rejuvenates forests. In fact, many species depend on fire for some aspect of their habitat or food supply. And as we've been relearning in recent years, fire is actually necessary to maintain a healthy ecosystem.
