Causes of Air Pollution In the world nowadays‚ there are many new inventions have invented. They are including cars‚ motorcycles‚ electronic gadgets and the machines that use the burning of fossil fuel. Instead of the benefits of these new inventions‚ there are many disadvantages‚ too. There are two main reasons that cause air pollution. One of the main causes of air pollution is manufacturing. This source of pollution spews particulate matter and chemicals into the atmosphere. The particulate

Climate change Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average (e.g.‚ more or fewer extreme weather events). Climate change may be limited to a specific region or may occur across the whole Earth‚ such as global warming. Terminology The most general definition of climate change is a change

Acid rain is a rain or any other form of precipitation that is unusually acidic‚ i.e. elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals‚ and infrastructure through the process of wet deposition. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive

AIR POLLUTION Air pollution is the introduction of chemicals‚ particulate matter‚ or biological materials that cause harm or discomfort to humans or other living organisms‚ or cause damage to the natural environment or built environment‚ into the atmosphere. The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth’s ecosystems

Lecture 5 Lizan A. Majeed Reading Paragraph Purpose Each paragraph in a text has a clear purpose. For example: The first paragraph introduces the topic‚ states the purpose of the text‚ or describes a problem or situation. The body paragraphs develop arguments‚ try to persuade‚ suggest solutions‚ or describe developments. The final paragraph concludes‚ evaluates‚ or discusses consequences. Identifying the purpose of each paragraph helps you understand the text and decide where

Air pollution is caused by humans. Smog and ozone layer depletion are two major causes. They are both toxics in the air that humans create and toxics that effect humans as well. Smog is caused by so many different chemicals that ranges from things like automobile exhaust to hairspray. It affects humans mainly in the circulatory and respiratory systems which are both very important and crucial to survive. Ozone layer depletion is a very serious decline of gas in the ozone layer which is bad because

to the ozone layer. Besides that‚ natural disasters‚ such as hurricanes; droughts; and floods‚ are becoming more frequent. The temperature at the Earth ’s Poles is also rising rapidly. The major factors leading to global warming are greenhouse effects and deforestations. In the past years‚ the impacts of global warming were not noticed or taken seriously by the public because the situation was not widespread and serious. In the recent years‚

AIR POLLUTION The major pollution caused by factories or industrials’ activities is air pollution. According to the Engineers’ Joint Council “Air Pollution and Its Control”‚ air pollution means the presence in the outdoor atmosphere of one or more contaminants‚ such as dust‚ fumes‚ gas‚ mist‚ odour‚ smoke or vapour in quantities of characteristics and of duration‚ such as to be injurious to human‚ plant or animal life or to property or which unreasonably interfaces with the comfortable enjoyment

Air Pollution in California In the 1940’s California was supporting a population of seven million people and contained 2.8 million registered vehicles. Within the next twenty years the population more than doubled to reach 16 million while the number of registered vehicles all but tripled increasing to eight million. This has been a common trend in California’s documented history from the early twentieth century to today. There have been many historical and environmental factors that have assisted

Climate Change in Developing Countries Over the past decade‚ human activity has started to cause an increased rate of negative change to our climate. Although climate change is a worldwide problem no one will feel the impact as harshly as third world countries such many parts of Africa‚ Asia‚ and South America. These countries are estimated to be hit the hardest by climate change even though they did the least to cause it. Developing countries have been struggling over the past few years on their
