Global Warming
The world is presently facing a crisis called Global Warming that should be stopped. It is important that people must get to know about this crisis that will affect the whole humankind, and try to stop it. The U.S. Environmental Protection Agency has states and local governments and businesses play an important role in meeting the national goal of reducing greenhouse gas intensity by 18 percent by 2012. Al Gore and other scientific experts can’t change global warming but we can take steps in order to decrease global warming: 1. Conservation and greater efficiency in the way you use your energy and resources. 2. Being a conscious consumer and being aware of the environmental implications on everything you buy, and every transaction you make in the marketplace. 3. And then becoming politically active regardless of what party you may be aligned with by insisting that the politicians of all parties take this as their top priority. Agricultural output in many poorer countries could be significantly reduced. An additional 80-90 million poor people could be at risk of hunger and malnutrition later in the 21st century; hundreds of millions of people will be at increased risk of malaria, dengue fever, yellow fever, encephalitis, and other infectious diseases because of global warming. Another fact, is contributing to the problem is a phenomenon known as Thermal Expansion- as seawater warms, it takes up more space so as higher temperatures from global warming heat the oceans and melt ice, the oceans will rise and encroach on what is now land. Also global sea level has already risen by four to eight inches in the past century, and scientists’ best estimate is that sea levels will rise by an additional 19 inches by 2100, and perhaps by as much as 37 inches. Of course, CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. They are looking at pumping liquefied carbon underground into old gas fields and oil wells. And, doing so might help get more oil from oil fields. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases. Another example is might be due to normal natural events but it could be also be that humans are accelerating the natural process by creating excessive amounts of pollutants. Global temperatures are expected to continue to rise as human activities continue to add carbon dioxide, methane, nitrous oxide, and other green house (or heat-trapping) gases to the atmosphere. Most of the United States is expected to experience an increase in average temperature. Unless we act now, our children will inherit a hotter world, dirtier air and water, more severe floods and droughts, and more wildfires. Most frequent and more intensive heat waves could result in more heat-related deaths. These conditions could also aggravate local air quality problems, already afflicting more than 80 million Americans. Global warming is expected to increase the potential geographic range and virulence of tropical disease as well.
Therefore if the world does not start to take steps to end global warming soon, the outcomes will prove to be castrophic.
