As more than 50% of biodiversity has been lost in 40 years; from 1970– 2010 (WWF Global, 2014, pgs 11 & 14), the need to understand and manage sustainably what is left becomes ever more important. Indeed, calculating the value, the state and the consumption of what remains of these natural resources helps to highlight, and consequently, create interest in the importance of managing such resources. If a value can be derived, markets can and have been created and both nature and people can benefit through increased sustainability and business.
