We humans who think of ourselves as the most intelligent things on this planet are intentionally or unintentionally destroying our own surroundings. One of the chief causes for global warming can be accredited to the behaviors of humans. It took more than twenty years for the world to finally accept that we humans are causing global warming with the emission of greenhouse gases which include carbon dioxide, methane, nitrogen oxide etc. the gases have formed an effect of green house on the earth’s exterior which prevents the reflection of the sun’s rays and therefore causes the boost in temperature. The radical boost in the emission of carbon dioxide in the last 30 years caused by burning fossil fuels has been recognized as the major reason for the change of temperature in the atmosphere.
Carbon dioxide concentration in the air has amplified because of the emissions from power plants, airplanes, cars, industries etc. one more reason for it is deforestation. Forests have been reduced making way for cultivation, industries and cities. The vegetation was natural regulators of carbon dioxide that controlled its level’s in the atmosphere. Eighty percent or more of the worldwide energy claim is currently supplied by the fossil fuels oil, coal or gas. It will be unfeasible to find alternative sources, which could restore fossil fuels in the short or medium term. The energy demand is just too high.
Another subject is the non-renewable traits of fossil fuels. It took our planet millions of years to produce these resources, while we will have used them up in about the next few decades. Alone the lessening supply will not make it possible to carry on as usual for a longer time.
