"Global fire crisis:" Why the world keeps burning and what we should do about it

When a California couple's gender reveal party sparked a 22,000 acre wildfire in 2020 that killed a firefighter, courts legally charged the duo for igniting the flames. But locating the source for the increasingly worsening "global fire crisis" isn't always this simple. 

Two-time Oscar-nominated filmmaker Lucy Walker said climate change is only one piece of the puzzle when considering why the world keeps burning. In her latest documentary, "Bring Your Own Brigade," Walker explores the complex roots of the worldwide wildfire problem, including legislation, the logging industry, forestry practices and infrastructure.  "It was really stunning to start to learn these other factors," Walker told CBS News' Vladimir Duthiers. "And that's really good news actually because it means we can do something about it. There are several factors where we can really stop this fire problem."
