We usually say that Earth is our home, our habitat, our native planet and so on. But what have we done to save and maintain it? Our common life couse polution, littering, greenhouse effect, animal extinction. So we mostly damage Earth‘s surfase and atmosphere.
The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases.Whenever we use the Air Conditioner, ride in a Car, microwave a Meal or when factories make the things that we buy and use everyday we are helping to send greenhouse gas into the air.Planting trees is a great way to reduce greenhouse gases. Trees absorb carbon dioxide, a greenhouse gas, from the air.Moreover, whenever we use electricity, we help put greenhouse gases into the air. By turning off lights, the television, and the computer when you are through with them, you can help a lot.The greenhouse effect is important. Without it, the Earth wouldn‘t be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.
-=PLUS=-SO, this is how it works: sunlight enters the Earth’s atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth’s surface biosphere absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up.
