Chemical Biodiversity and its Industrial Applicability
Biodiversity - the huge variety of living forms that makes up our biosphere - is a concept introduced in the scientific world by the Nature explorers in the last 400 years. As there was no formal division among areas of knowledge, scientists of the time had a comprehensive education in natural sciences, which encompassed physics, chemistry and medicine. Frequently their contributions had to do with several knowledge areas. In the 20th century, with knowledge being segmented into disciplines, the word "biodiversity" lost its importance until the defenders of the Environment, in a memorable campaign, succeeded in turning the biological diversity cause into a worldwide objective in itself, embodied in the CBD1 - the 1992 Convention on Biological Diversity, also known as Rio-92.
