Environmental issues: Importance of Biodiversity
The diversity of species both flora or fauna have very important roles in the survival of mankind. Biodiversity is a crucial natural resource for humans. Many species that are threatened could potentially provide economic values for human use [1]. Levels of Biodiversity[1] 1. Genetic diversity Genetic diversity comprises not only the individual genetic variation within a population, but also the genetic variation between populations that is often associated with adaptations to local conditions. If one population becomes extinct, then a species may have lost some of the genetic diversity which in turn reduces the adaptive potential of the species [1]. A good example of the importance of genetic diversity is production of rice. Having more varieties of rice contribute to its gene pool. This is very useful in improving the crop quality. One variety of rice may have genes for virus resistance, another with genes resistant to insects. These qualities can be combined t...
