The term biodiversity - the presence of a large number of species of animals and plants - is now recognized as being important by many people. To most people, the existence of many species is important because their psychological differencies furnish various sources of food, clothing, shelter and medecine for man. Species also differ in their physical and chemical characteristics, which is true of plants. For example we have cotton, flax and ratan which are all products of various species of plants and are used for different types of clothing. Likewise, the structure of plants, be they trees or palm fronds or bamboo poles, serve as a source of shelter for much of the human race. Therefore, from the human standpoint, the presence of a great number of species with different structures, different chemical compositions and different lifespans from one of the most important bases of life for humans throughout the planet.
Also these aspects are very important to society,there are far more important aspects of biodiversity that many people do not realize. For example it is the presence of different kinds of plants that make up the food of grazing animals for example grass, herbs and fruits. It is this great diversity of plant life with its varying fodd values that enables the existence of many different kinds of animals. |
