INTRODUCTION
One of the greatest attributes of the Earth is the biodiversity of her ecosystem. The Convention on Biological Diversity (Article 2) defined biological diversity or biodiversity” as the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems”.2 This is a reflection of the more than 9 million types of living thing which include fungi, bacteria, plants, animals, protists that co-inhabit the Earth with human beings and serves as the bases of the diverse array of organismal, genetic and ecological diversity obtainable on Earth.3 The complex interplay between this rich array of Earth’s inhabitants underpins the proper functioning of the Earth’s ecosystem. However, the last few decades, have witnessed a rapid disruption and loss of this rich biodiversity in terms of numbers and variability. Human beings are relentless than ever in eliminating genes, species, and biological traits that constitute the biodiversity via her disruptive activities on the Earth ecosystem.
