I think that by this you can notice how global warming is being the sources of many environmental problems and death of people.
Greenhouse Gases According to scientists' opinions, the representative reason of Global Warming is Greenhouse Effect. There are many kinds of gases in the atmosphere, but just some of gases are revealed to influence Greenhouse Effect. We call the gases Greenhouse Gases. The gases make Greenhouse Effect much stronger by holding warmth or making reflective layer that confines warmth. Greenhouse Gases are, for example, carbon dioxide(CO2), methane(CH4), nitrogen oxide(N2O), chlorofluorocarbons(CFCs), and some little influential gases. From now, I will refer to the gases one be one with the reason of them. First, carbon dioxide(CO2), people release of carbon dioxide contributes most to the enhanced greenhouse effect. When we burn fossil fuels, such as coal and oil, contain carbon, and carbon dioxide must be released. As world demand for energy increases, so more fossil fuels are being burnt, so carbon dioxide's level is rising. All green plants remove carbon dioxide from the atmosphere and use sunlight energy to convert it into carbohydrates. And, the carbohydrates provide food to ecosystem. However, people are destroying them. It is one of big reason to increase carbon dioxide's level. Second, methane(CH4), methane is produced by anaerobic bacteria which live in marshes, landfill sites, rice paddies and in the guts of ruminants that are for example, cattle, sheep, camels. A cow may release a phenomenal 200 litres of methane a day. All ruminants make 25 percents of the whole methane. Leaking gas pipes and coal mines also release methane. Third, nitrogen oxide(N2O), nitrogen oxide is released during fossil fuel combustion and from denitrifying bacteria which act on nitrates and nitrites. Increasing use of nitrate fertilizers and increasing cultivation of soils make nitrogen oxide's level increase. Finally, chlorofluorocarbons(CFCs), chlorofluorocarbons have been used as coolants in refrigerators, as propellants in aerosols and as expanders in expanded foam products. Their increasing concentration in the atmosphere over the last two decades reflects their wide usage. The Montreal Protocol has led to a huge decline in the production of chlorofluorocarbons but, unfortunately, chlorofluorocarbons that have already been released into the atmosphere will stay there for many decades. They have a long residence time. Moreover, according to U.N report, alternative chlorofluorocarbons are good at preservation of the Ozone Layer, but it influence Global Warming like a chlorofluorocarbons. We've concretely searched about Greenhouse Gases and its reasons. There are many of other Greenhouse Gases. But, I didn't mention about them, because the influencing power of other Greenhouse Gases is so little. How to control the gases that I've mentioned above? It is our main homework to solve the global warming. This is a chart showing the annual greenhouse gases that are produced wirtten by Lee Chol Won

How people are involved to the effect of the global warming.
There are many straight phenomena in the world. For example, it becomes the earth is warming seriously. Because the temperature of earth has steady increased since the Industrial Revolution. Global warming during the past century has been so gradual as to be nearly imperceptible. Almost people couldn’t realize the problem of Global warming, but it is very serious operation.
Global warming causes a number of potential challenges for public health. It causes serious diseases such as malaria, black vomit, inflammation of the brain, consumption, a stomachache, cholera, pneumonia, inflammation of the liver, ebola virus. It is developed gradually, but it is hard to feel seriousness of the sick. There are many people who is dying as being effected by Global warming.
Succession of historical movement of greenhouse gas emissions will result in additional warming over the 21st century. It will be current projections of a global increase of 2.5ºF to 10.4ºF by 2100. It is warming in America expected to be even higher. This warming will have real consequences for the U.S. and the world.
The predicted effects of global warming for human life are numerous and varied. The important effect is an increasing global average temperature. From this flow a variety of resulting effects, rising sea levels, altered patterns of environment, increased extreme weather problems, and the expansion of the range of tropical diseases. In some cases, the effects may already be occurring, although it is generally difficult to attribute specific natural phenomena to long-term global warming.
