WHAT IS G.W?G.W: Phenomenon that the average

temperature of the earth’s surface is increasing.

Cause: Excessive emissions of G.G(greenhouse gases) and excessive using of fossil fuel.

Effect of Human activi-ties 1

Cut trees

More CO2

Less Oxygen

Trees purify the air.

The Earth is heated.

Effect of Human activities 2

More CO2

Exhaustion of resources

To make electricity, we use fossil fuel.

The Earth is heated.

Use elec-tricity.

Effect of Human activities 3

Take a car.

More CO2

More HC

The Earth is heated.

Vehicle exhaust contains CO2.

Impact(result) of G.W 1

The Earth is heated.

Glacier melts.

No place for polar bears

to live.

Impact(result) of G.W 2

The Earth is heated.

Sea level in-creases.

Some low countries would be sunken.

ex) Mal-dives

Impact(result) of G.W 3

The Earth is heated.

The cli-mate is changed.

Some plants or

animals die.

Because they couldn’t adapt the new climate.

Two camps of G.W -First Camp1

First camp: People egg G.W on.

The main cause of G.W is excessive emissions of G.G.

People made

most G.G.

The main causes are from peo-

ple.

Two camps of G.W -First Camp2

Two camps of G.W -Sec-ond Camp1

The cause of G.W is not certain.

CO2 comprises only 0.03% in atmosphere.

Would the increasing of 0.03% of at-mosphere, CO2 be a main cause of G.W?

Two camps of G.W -Sec-ond Camp2

Although the cause of G.W is G.G, a cow makes more G.G than

a car.

Global warming is just a natural

happening.

Solution for G.W

Campaign-Earth Hour : turn all of the lights for an hour.

Habit-Use public trans-portation, unplug, and use mug.

The others-plant trees.

Conclusion 1

G.W: a phenomenon that tempera-ture increases.

People’s activities affect G.W.

Result: People, plant, and animals die.

First camp (cause is people)

-G.G is a main prob-lem of G.W

-People make most G.G

Second camp(G.W is natural)

-A cow makes more G.G

-Cause of G.W is not curtain

Solution: Unplug, use public transportation,

plant trees

Conclusion 2

Whatever the cause is…

We have to stop the G.W!!!
