Because of the fiction movie Farewell Atlantis, the view of doomsday is making a great clamor. Mayans once predicted December 21, 2012 is the end of the world. Under the influence of the movie, many people believe this saying. Or rather, doomsday means the end of human civilization. Actually, Farewell Atlantis is the alarm bell to human beings that we should protect our planet, culture and civilization. Otherwise, the doomsday will come soon. Besides, it reminds us of cherishing our families and friends, because you never know what will happen next second.

Global Warming What is global warming? 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. What is the greenhouse effect?The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows, but it can’t get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere, but it can’t get out. As a result, the temperature rises. What causes global warming? Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants chemicals that pollute the air, water, and land are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses. What is global warming doing to the environment?Global warming is affecting many parts of the world. Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. This is a big problem for many of the plants, animals, and people on islands. The water covers the plants and causes some of them to die. When they die, the animals lose a source of food, along with their habitat. Although animals have a better ability to adapt to what happens than plants do, they may die also. When the plants and animals die, people lose two sources of food, plant food and animal food. They may also lose their homes. As a result, they would also have to leave the area or die. This would be called a break in the food chain, or a chain reaction, one thing happening that leads to another and so on. What are greenhouse gasses?Greenhouse gasses are gasses are in the earth’s atmosphere that collect heat and light from the sun. With too many greenhouse gasses in the air, the earth’s atmosphere will trap too much heat and the earth will get too hot. As a result people, animals, and plants would die because the heat would be too strong. 我也写过这样的作文，这些是从我的作文里面的一部分， 希望能帮助到。
