A moth outbreak has killed off forests across Siberia, now the flammable wood is causing wildfires that humans are unable to contain

• An insect outbreak has left Siberia's forests dead while also transforming the region into a tinderbox where wildfires are now spreading beyond human control.
• The trees burning across Krasnoyarsk this year were, in a lot of cases, already dead.
• Not from the fire or the drought, but because of a small moth.
