“Change is the only truth!” is an old adage that has transcended and withstood the challenge of time. Changes world around are happening progressively at a faster pace with each passing year. The amount of human activity and the magnitude of greenhouse gases being created within the last one human generation exceeds that entire amount that was possibly generated during the past 10000 generations (Guggenheim, 2006). So unfathomable is the impact of human development on the world we live in. This presents the world innumerable and diverse problems.
