Wildfires can start naturally from dry grass rubbing together or lightning strikes, but are also frequently caused by human activities like campfires or discarded cigarettes. Wildfires spread extremely quickly and can destroy everything in their path, making evacuation critical when they approach. Firefighters have developed strategies to control and extinguish wildfires, such as dropping water or retardant from aircraft or using giant hoses. The best approach is preventing and quickly detecting wildfires so that firefighters can respond before they grow out of control.

1. My Amazing Bill Nye Speech

2. Dennis: Hi everyone my name is Dennis.
Hena: I’m Hena.
S-C: and I’m Seok Chae.
Dennis: We are scientists.
Hena: We know ALL about wild fires.

3. S-C: A wild fire is a fire that happens in nature.
Hena: A wild fire is any uncontrolled fire.
Dennis: It can happen in the countryside or a wild
area or a forested land.

4. S-C: Lot’s of things can start wildfires. Hena: Did you know
that wild fire can made by nature? Dennis: For example, dry
grass and dry grass rub together sometimes, causing heat and
it makes a forest fire. Sometimes lightning strikes start fires.
This is the natural cycle of the forest. S-C: Did you know that
wildfires can also be made by humans? Some campers light
fires too close to dry leaf litter. Sometimes farm fires get out
of control. Hena: A few fires are also started by people who
throws matches or cigarette butts.

5. S-C : Forest fires are very dangerous. Dennis: If your house is
burning, Hena: you need to evacuate. Dennis: Fires can
spread VERY quickly. Hena: And wildfires can destroy every
living thing in its path. S-C: Forest fires in the wild can quickly
burn up large areas of land. S-C: In the wild car moves so
quickly Hena: but they may still be in danger from a moving
fire. Dennis: Fires can change direction and destroy
communities without warning. The fire might circle the
community and they have no way to escape.

6. Hena: We must evacuate when there is a wild fire coming – if possible.
S-C: Did you know fire fighters use special methods to control and put out
fires? Dennis: That’s right. May towns employ fire chiefs to be prepared for an
emergency. Sometimes they even start small new fires. Hena: So that the next
wild fire won’t have as much fuel to burn.
S-C: Firefighters might drop sand or water from helicopters. This stops the fire
from having oxygen. They might also hit the with a wet blanket.
Dennis: Firefighters sometimes use a retardant- which is a foam that stops
things from burning.
Hena: Firefighters might use giant hoses to wet houses before the fire arrives.
Dennis: This slow down the evaporation and the burning.
S-C: As you can see, there are many ways that firefighters respond to fires.

7. Dennis: The best thing, of course, is if we can detect or
predict a wild fire before it happens.
Hena: People who live in the countryside can be keep watch
for fires so they can tell the firefighters quickly.
S-C: In some areas, automatic weather stations are set up.
Hena: The stations send information about
temperature, humidity and wind speed.
Dennis: The information arrives by radio. It is marked on a
map so people can find the exact place of a fire.
S-C: Also, some towns build large danger meters to warn
people are the risk of fire.
Dennis: People try to have plenty of time to evacuate!
Hena: Let’s go!

8. S-C: So, to wrap it up, be careful where you light fires in a
forest.
Hena: Always listen to firefighters to protect your house and
your life.
Dennis: Everybody needs to detect fires to protect our planet
Earth.
All: Good bye!
