Effects of Technology

We only have this Earth . Nowadays, people devise many items to let us live more convenient , but in the same way , they pollute our environment . For example , the plastics makes carrying easier , but it cannot decompose by nature; the air conditioning makes inside air temperature cooler ,but it discharges carbon dioxide to cause globalwarming . Now , the most important topic is “Globawarming,” and the main murderer is carbon dioxide . A great deal of carbon dioxide will cause the green house effect .What is a green house effect? The carbon dioxide is a kind of glasshouse air, it will shoot the sun to the permafrost thermodynamic energy to trap, causing the temperature on Earth 's atmosphere rise gradually, and this is how green house effect works . This is a very horrible . The temperature is higher than before , causing the icebergs which in the polar circle melt . And then , the sea level rises . Many islets are submerged , and a lot of human are homeless . The scientists want to solve globawarming , but they think out the most effective way is making the carbon dioxide less .
Taiwan was a very beautiful island before , but now it’s full of pollution .The air pollution , water pollution , and environment problems are the major problems in Taiwan , in these case would nothing be more serious than air pollution . The sky in Taiwan become darker and darker . It is not blue no longer . Why? Who destroy it ? We kill it ? We still produce air pollution . The cause of air pollution is mainly from automobiles, factories, power plants, and Incinerator etc. to exhaust a great deal of waste gas. In addition, the dust that floats in the sky in the construction engineering and the cement works, second-hand smoke and some chemistries air etc. that sends forth smoke cigarette to exhale, also will pollute the environment .However , we know what happen at our problems , but we are at a loss what to do . Producing is faster than solving . People don’t care about this kind of problem . Everyone is still to do his business . Only few people concerned with environmental trouble . We only have this Taiwan , we only have this Earth . We should protect them , but we are having murdered them actually . Therefore , we all need environmental consciousness , this is not the slogan in the textbook , this idea must to being in all human being . Protecting environment is very important thing , Giving our children a beautiful environment ,not the dirty world ,Because we only have this Taiwan , we only have this Earth .
