Document Summary

Human interference with different habitats and ecosystems have greatly increased the rate of extinction. An applied scientific discipline devoted to preserving the diversity. The embracing of certain values and the application of the scientific method in order to achieve these values. Although the processes of species extinction is a natural one, which has been done for millions of years, conservation biology aims to prevent the extinction of animals. For the first time in history, one species of ecosystem engineers (humans) are the cause of all major environmental changes, which disrupts the natural course of extinction/evolution of different species. Humans depends on other species for food, fibre and medicine. Humans derive aesthetic pleasure from interacting with other organisms. Causing the extinction of other species raises serious ethical issues. Extinctions make the study of ecological relationships and species interactions difficult: more species lost/extinct, the more harder it is to understand the structure and the functioning of ecological communities and ecosystems.
