Global Warming !!

Global Warming has been one of the most important enviromental hazardous problems for the past 100 years. Global warming is an increase of certain gasses that are produced which trap the sun's heat in the atmosphere.

Over the last 100 years, the global average temperature has increased by approximately 0.6 degrees C and is projected to continue to rise at a rapid rate. Although species have responded to climatic changes throughout their evolutionary history, a primary concern for wild species and their ecosystems is this rapid rate of change.
