Biodiversity is the unit of variation of life. It can refer to genetic variation, species variation, or ecosystem variation which seems to be the result of the warm climate and high primary productivity. Biodiversity usually tends to bunch in hotspots, and the number has been growing through time but will be likely to slow in the future. According to Lemons and Morgan (1995) study the biological diversity defines as “the variability among living organisms from all sources and ecological complex of which they are a part; this includes diversity within species, between species and of ecosystems’’. These biodiversity has so much importance value that keeps supporting the Earth ecosystem. In general, the biodiversity can be classified into 3 major importances: sources of food, pharmaceutical industry and ecological services. (refer to Figure 1 in Appendix 1) Firstly, biodiversity is very important in providing sources of food. Biodiversity of life on Earth is functioning like a support system to human life and human rely on it every day. These biodiversity did provide human beings with free of charge natural resources such food product, shelter, air, water, and many more. Generally human consume the foods which come from natural sources of the biodiversity. Biodiversity provides many varieties of food such as livestock, crops, fisheries, and forestry which are an important food source. These foods provide necessary nutrient such as carbohydrate, fiber, protein and vitamins. It has been estimated that some 30,000 species are edible, however only about 7,000 of these have been cultivated or collected for food by humans (WEHAB Working Group, 2002). Human has started the agriculture industry to cultivate and collected species that can be ... ... middle of paper ... ...e tapestry of life.
