Global warming is one of the most serious challenges facing us today. It is already affecting the world as we know it; endangering polar bears‚ shortening ski seasons and creating more intense storms. Global warming is caused by the build-up of greenhouse gases in the atmosphere‚ hence increasing the average temperature of the earth. Scientists have stated that the average temperature will likely rise a further 1 to 6 °C still during the 21st century. Global warming is causing numerous problems

to live and breathe. Global deforestation is growing at an alarming rate -- every year‚ 13 million hectares of forest are destroyed. Anthropogenic factors that can affect forests include logging‚ urban sprawl‚ human-caused forest fires‚ acid rain‚ invasive species‚ and the practice of shifting cultivation. If forests disappear‚ the amount of Carbon Dioxide in air will increase‚ resulting in increase of temperature of earth. Furthermore‚ it would cause global warming as the Carbon Dioxide

the year 2007‚ the concept of ‘Sustainability’ was established in the mind of people and businesses in the world. In the year 2009‚ the UN Climate Change conference held in Copenhagen firmly developed the issue of potential threats of global warming in both the global political and business arenas.

Global warming started to occur around the late 19th century‚ and it continues to proceed to increase as time goes on. The main gases to blame for global warming are Carbon dioxide‚ Methane‚ and Nitrous Oxide. These gases are trapping the heat inside the atmosphere causing the temperature to rise‚ this process is also

Deforestation Deforestation is clearing Earth’s forests on a massive scale‚ often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area‚ but large areas the size of Panama are lost each year. The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation. Reasons for Deforestation Forests are cut down for many reasons‚ but most of them are related to money or people’s need to provide for their families
