00:00:00,900 --> 00:00:03,870

But it's not just the fire itself

that's dangerous.

2

00:00:03,870 --> 00:00:08,108

Wildfire smoke can travel

for thousands of miles, having the ability

3

00:00:08,108 --> 00:00:11,578

to blanket large swaths of a continent

from a single wildfire.

4

00:00:12,212 --> 00:00:14,781

Smoke from wildfires

can reach high altitudes,

5

00:00:14,781 --> 00:00:18,151

between 3 to 6 miles, and travel

with prevailing winds.

6

00:00:18,952 --> 00:00:22,856

This smoke can linger in the air

for several weeks, changing the chemistry

7

00:00:22,856 --> 00:00:26,192

of the atmosphere, and reducing the amount

of sunlight reaching the surface.

8

00:00:27,260 --> 00:00:30,030

Smoke that gets trapped

near the ground severely impacts

9

00:00:30,030 --> 00:00:32,432

the air quality in surrounding communities,

10

00:00:32,432 --> 00:00:34,934

and poor air quality can last for months

11

00:00:34,934 --> 00:00:37,203

as large fires continue to smolder,

12

00:00:37,203 --> 00:00:40,373

even after the fire itself has been contained.
