SEQUENCE What is G.W? Effect of human activities Impact(result) of G.W Two camps of G.W Solution 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 activities 1 Cut trees More CO2 Less Oxygen Trees purify the air. The Earth is heated. 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. The Earth is heated. Use electricity.

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 increases. Some low countries would be sunken. ex) Maldives

Impact(result) of G.W 3 The Earth is heated. The climate 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 people. Two camps of G.W - First Camp2

Two camps of G.W - Second Camp1 The cause of G.W is not certain. CO2 comprises only 0.03% in atmosphere. Would the increasing of 0.03% of atmosphere, CO2 be a main cause of G.W? Would the increasing of 0.03% of atmosphere, CO2 be a main cause of G.W?

Two camps of G.W - Second 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 transportation, unplug, and use mug. The others-plant trees.

Conclusion 1 G.W: a phenomenon that temperature increases. People’s activities affect G.W. Result: People, plant, and animals die.

First camp (cause is people) -G.G is a main problem 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!!!
