2. Fight Against Global Warming Global Warming is one of top serious problem as well in these years, we should take more responsibilities to face with it. Because we are humanbeing and that’s what we’ve done to our earth. NextEnd By C20509 王毓華 Claire Wang 有聲音 ! 記得開喇叭喔 ^^

3. "What Is Global Warming?" HomeNextEnd Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die

4. Global Warming effects Up 5 Deadliest Effects of Global Warming 1.Polar ice caps melting it will raise sea levels 2.Economic consequences melting ice caps will throw the global ecosystem out of balance 3.Increased probability and intensity of droughts( 旱災 ) and heat waves ( 熱浪 ) Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves. 4.Warmer waters and more hurricanes ( 颶風 ) As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes. We saw in this in 2004 and 2005. 5.Spread of disease As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them. HomeNextEnd

5. What causes Global Warming? Global Warming is caused by many things. The causes are split up into two groups, man-made or anthropogenic causes, and natural causes. Natural Causes  Natural causes are causes created by nature. One natural cause is a release of methane( 甲烷 ) gas from arctic tundra( 北極苔原 ) and wetlands( 沼 澤地 ). Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years. Man-made Causes  Man-made causes probably do the most damage. There are many man-made causes. Pollution is one of the biggest man-made problems.  Burning fossil fuels( 燃燒化石燃料 ) is one thing that causes pollution  Another major man-made cause of Global Warming is population. Some other examples of using energy and polluting the air are: 1.Turning on a light 2.Watching T.V. 3.Using a hair dryer..etc UpHomeNextEnd

8. My personal opinions Saving our environment ＝ saving our lives 環保議題一直是我們最注重的，從分類開始一直到 推行許多綠化的活動，從這些細微的觀察裡， 我們都能看到地球村子民的一步一步改變，這 是我們的地球、是我們的母親，也許我們無法 抑制暖化的速度，但是只要一個人願意從此刻 開始改變，只要十個人願意開始改變，只要一 百個人願意改變 ………. ，我深信我們的社會我 們的地球將會有所不同。 Go Green 也是國外非 常提倡的綠化活動之一，減少使用環保袋、減 少使用可能會汙染大氣層的氣體用具、減少能 源的消耗 … 等等，這些都是最好的行動證明我 們愛我們的地球，別再自私下去了！拯救地球 已經刻不容緩了！因為 : 我們是地球村的一份子， 這是我們的地球，我們不能自私下去了，我們 要把好的環境留給我們的下一代，讓他們也能 享受和感受到地球的美好！ UpHomeNextEnd
