Global warming

Global warming is the average temperature of Earth has increases since 1950 until now the temperature continuing increasing. Global warming can also refers to climate change that causes an increase in the average of temperature. However global warming are causes by natural events and human that are believed to be contribute to increase in average temperatures. Global warming is a serious issue and is not a single issue but a number of environmental issues. Global warming is a rise in the surface temperature of the earth that has changed various life forms on the earth.
The climate has continuously changing for centuries. The global warming happens because the natural rotation of the sun that changes the intensity of sunlight and moving closer to the earth. Volcanic eruptions are another issue that causes global warming. For instance, a single volcanic eruption will release amount of carbon dioxide and ash to the atmosphere. Once carbon dioxide increase, the temperature of earth increase and greenhouse trap the solar radiations in the earth.
These activities cause excessive amounts of carbon dioxide to set off into the atmosphere, which in turn prevent heat from escaping the earth and slowly cause our ozone layer to deplete. Burning of fossil fuels is the most common example of carbon dioxide release. Humans burn these natural resources in order to obtain gas necessary for transportation methods. Gas is needed in nearly all automobiles, buses, planes, and trains. In addition, vehicles also produce exhaust, further polluting the air.
Deforestation augments the greenhouse effect as well. Plant life engrosses carbon dioxide just as humans take in oxygen. When land is cleared, a great deal of vegetation is removed along with it. When land is cleared, a great deal of vegetation is removed along with it. Because of these actions, carbon dioxide that remains unabsorbed by plants is left in the atmosphere. Another gas by the name of methane is also harmful to the environment.  
Methane is also a greenhouse gas. Methane is more effective in trapping heat in the atmosphere that carbon dioxide by 20 times. Usually methane gas can release from many areas. For instance, it can be from cattle, landfill, natural gas, petroleum systems, coal mining, mobile explosion, or industrial waste process. Human influence has been a very serious issue now because human do not take care the earth.
Human that cause global warming are more than natural causes global warming. Human influence has been a very serious issue now because human do not take care the earth. Human that cause global warming are more than natural causes global warming. The earth has been changing for many years until now it is still changing because of modern lifestyle of human. Human activities
include industrial production, burning fossil fuel, mining, cattle rearing or deforestation.
The greenhouse gases will stay in the atmosphere for many years since hundreds years ago. However, the effect that global warming will cause on earth are extremely serious. There are many effects that will happen in the future if global warming continues. That includes polar ice caps melting, economic consequences, warmer waters and more hurricanes, spread of diseases and earthquake.
 It also affects the economics of the country. However, we need to be reduce the global warming by using less gasoline, recycle and human should help to reduce global warming instead of making the
earth temperature increased. Our generation should start taking care of the earth because in the next generation they will suffer if we do not do reduce global warming. Therefore, global warming is a serious issue now. As a business student we are learning it because we need to understand the effect of climate change that will affect us when we have our business and we can start saving the earth.
