Air, the most important thing on the earth for people to be alive. No one can live without air. What is “Air”? The atmosphere of Earth is the layer of gases, commonly known as air, that surrounds the planet Earth and is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (Wikipedia). Since air is very important for people to live in this world, every government tries to give the residents a better environment, especially the air. A better air is also good for people’s health and keep healthy. As we all know, Beijing has a big problem of air, haze, and all the residents in Beijing feels so bad because they have to have a mask with them when they are outside. In addition, haze is full of harmful things for people to breath and sometimes people there cannot recognize whether it is day or not. Haze also can not let people enjoy sunshine. Therefore, looking at the haze that is in Beijing, almost every country and big city tries to improve the air and prevent from having haze. Chicago is home to vibrant urban forests, prairies, and wetlands. Through continuous restoration, outreach, and research efforts, the city prioritizes protection of these natural areas. Mayor Emanuel recognizes that investments in such resources help improve people’s quality of life, create jobs, and attract tourism (City of Chicago).

On August 3rd, President Obama announced the Clean Power Plan – a historic set of Clean Air Act standards that will finally put an end to the era of unlimited carbon pollution from the nation’s fossil fuel-fired power plants. As people know, the emissions of carbon dioxide are the first biggest pollution to the air. In the U.S., almost everyone has a car and uses it everyday. Therefore, reducing carbon pollution from the power sector will yield a safer and more stable climate for ourselves and for our children (Bianco & Carbonell). In addition, the reductions in carbon pollution required under the final rule are abundantly achievable. This rule is expected to reduce emissions of carbon dioxide from the power sector to 32 percent below 2005 levels by 2030. Emissions reductions are required beginning in 2022, two years later than would have been required under the proposed rule (Bianco & Carbonell). Moreover, the Clean Power Plan will finally put an end to the era of unlimited carbon dioxide emissions from the nation’s fossil fuel- fired power plants, by creating consistent national emissions standards for sources that are responsible for nearly forty percent of the nation’s carbon pollution (EDF). According to the data from EDF, historical CO2 emissions from the power sector come from EPA’s Greenhouse Gas Emissions Inventory. In addition, reductions in carbon dioxide pollution required under the Clean Power Plan will be from 2000 to 1500 between 2015 and 2030 (EDF).

Clean air is very significant for everyone who lives in the earth, and everyone knows that we need a clean air to be able to have a healthy life. With the development of technology and energy, more and more kinds of pollution have been made by people. Even though it is hard to get the clean air back from a worse air, such as haze, people still can do some steps to prevent the air from being polluted.
