Extinction is a natural phenomenon. It is es 99% cles that ever lived are now extinct. Why then do we say that we are now experiencing an extinction (loss of biodiversity) crisis? Humans have greater medical needs than at any other time in history, and many potential medicinal compounds are being lost as plant species become extinct. OScientists have finally identified most of the species on Earth and are thus able to quantify the number of species becoming extinct. Most biodiversity hot spots have been destroyed by recent ecological disasters. The current rate of extinction is high and human activities threaten biodiversity at all levels.

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.
