Apart from these all, information technology has served human kind in a manner nobody expected it to initially. Information technology has helped reducing the global warming throughout our planet.
Global warming is one of the gravest dangers posed to the environment in today's era, due to the emission of green house gases. Recent discoveries including the scientific advances in Information Technology have drastically reduced the carbon emission of the globe by decreasing the energy need created by internet processing of multiple tasks including the bank transactions, online ticket booking, shopping etc. Moreover, the non-renewable sources of energy utilized to generate the power for these IT transactions could be further reduced with the help of 'Green Technology'.
"Two thousand scientists, in a hundred countries, engaged in the most elaborate, well organized scientific collaboration in the history of humankind, have produced long-since a consensus that we will face a string of terrible catastrophes unless we act to prepare ourselves and deal with the underlying causes of global warming."
Global Warming - Global warming is the dramatic and unexpected surge in temperature of the climate, which is a common abode for many different species and not just human beings, caused as a result of series of negative human activities like burning of fossil fuels( coal, oil and gas) and large scale deforestation. Burning of fossil fuels releases a large amount of greenhouse gases such as carbon dioxide, methane, nitrous oxide and chlorofluorocarbons (CFCs). These gases act as a thick blanket and absorb thermal radiations emitted by the earth's surface, thereby resulting in the planet to warm up significantly. According to the reports of Intergovernmental Panel on Climate Change, global greenhouse gas emissions have grown with an increase in 70% between 1970 and 2004.
The increase in temperature is a kind of anomaly in ecosystem and this anomaly will cause severe storms and droughts, glaciers to melt, rising seas, changes in weather pattern and spread of diseases. There will be an increase in the sea level and the low lying islands will be left completely devastated. The inhabitants of the cities as well as other vegetation will see a dramatic increase in pests and other insects that will thrive due to an increased temperature, thus leading significantly to unexpected calamities. Loads of animal and plant species will be extinct and the habitat such as coral reefs and alpine meadows will be disheveled. Heat waves, due to global warming, have already caused a loss of 30,000 lives in Europe and 1500 deaths in India, in the year 2003.
In this difficult time of global warming, IT has played a decisive role in saving energy. IT has efficiently changed all the conventional modes of getting a task done to a more simplistic manner and provides not only relatively cheaper solution at a faster pace but also saves a tremendous amount of energy. Imagine the amount of energy spent if everyone uses conventional sources of energy by literally going at a bank to do every enquiry or pay his/her bills or do a railway booking and to do shopping and not using the internet every single time. Moreover the amount of papers
