It cannot be argued that the growth rate of world population has drastically increased over the years. Whilst reaching the figure of 5 billion has been a challenge to the world, the sixth and seventh billions of people were added to global population in record 12 years time (Haub & Gribble 2011).

With the short-term focus of daily human activities, environmental degradation in the long-term is inevitable (Cassils 2004). As Lam (2011) points out, increased level of various commodities consumption is becoming less sustainable and this adds to overall environmental suffering of the world.
