Global warming is one of the most serious crises in the world. The global temperature is rising, and it will cause terrible problems to the planet. From the movies we can see that if the world warms by four degrees, oceans will rise and overtake heavily populated deltas which are homes to billion people. Egypt will be inundated. Venice will be submerged. Glacier will disappear. Northern Canada will become one of the planet’s most bountiful agricultural zones. The entire West Antarctic Ice Sheet could collapse sending sea levels rising even further. This could be our world plus four degrees. The planet will become unrecognizable from what we’ve known today. We’ll see the possible drying up of some of the most important rivers in the world. And this will endanger the survival of millions of people. If the world warms by five degrees, snow pike that feeds the world great cities: Los Angeles, Cairo, Lima, Bombay will be drying out. Hundreds of millions of people will become climate refugees. This could be our world plus five degrees. People will be unable to withstand that kind of climate shock. If the world warms by six degrees, desert will expand. Natural disasters will become common events. Some of the world’s great cities will be flooded and abandoned. This could be our world plus six degrees. Six degrees of warming is been called the doomsday Scenario. Our lives would never be the same again.
Global warming is a serious problem that all humankind have to face right now. Human activities cause carbon dioxide and other heat-trapping gases which will damage the atmosphere. We have to take measures immediately or our world will be destroyed. For individuals, we have to become more energy efficient. There are many things that we can do to save the earth. We should start using compact fluorescent bulbs which last much longer than the familiar incandescent light bulbs and are lower energy use. And while buying appliances such as refrigerators or air-conditioners, choose the one with the highest energy efficiency rating. Also, while buying cars, you should buy the one which is fuel efficient. Hybrids are cars that combine an internal combustion engine and a battery-powered electric motor. This kind of car is environmentally friendly vehicle. Buying cleaner cars can help reduce carbon dioxide emissions effectively, because the carbon dioxide emission from cars is one of the primary CO2 emissions. We should unplug appliances and electronic devices such as computers and TVs while not using them to avoid the " phantom load." The government should develop laws which can protect our environment. We only have one earth, if we don’t protect it, we will confront far more difficult situations in the future.
