SEQUENCEWhat is G.W?Effect of human activitiesImpact(result) of G.WTwo camps of G.WSolution for G.W
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!!!
