What is BIODIVERSIT Y?
Shortened term for Biological Diversity. Refers to a variation of life at all levels of biological organization. “Div er sity” i n thes e de fi ni tio n inc lud es div ersit y withi n a s pec ies an d a mo ng spe cie s, and co mpa rativ e d iver sity a mon g eco system s. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse earth.

Biod iv ersity i s a ne ol ogi sm a nd p ortma nt ea u word, f rom b iol ogy an d div ersit y. Since 1986 the terms and the concept have achieved widespread use among biologists, environmentalists, political leaders, and concerned citizens worldwide. It is generally used to equate to a concern for the natural environment and nature conservation. This use has coincided with the expansion of concern over extinction observed in the last decades of the 20th century.
Evolution and M
eaning
The Science Division of The Nature Conservancy used the term "natural diversity" in a 1975 study, "The Preservation of Natural Diversity." The term biological diversity was used even before that by conservation scientists like Robert E. Jenkins and Thomas Lovejoy. The word biodiversity itself may have been coined by W.G. Rosen in 1985 while planning the National Forum on Biological Diversity organized by the National Research Council (NRC) which was to be held in 1986, and first appeared in a publication in 1988 when entomologist E. O. Wilson used it as the title of the proceedings of that forum. The word biodiversity was deemed more effective in terms of communication than biological diversity.
Why is Biodiv ersit y Important ?
Biod iv ersit y refle cts t he num be r, v ariet y an d varia bi li ty of l iv ing or gan isms as w ell a s ho w thes e c han ge fr om o ne loc at ion to ano the r a nd ov er tim e. A diverse ecosystem is important. Ecosystems provide the basic necessities of life such as food, clean air and water. They offer protection from natural disasters and disease, shape human cultures and spiritual beliefs, and maintain the planet’s essential life processes. Biod iv ersity a ctu all y bo os ts eco system pr odu ct iv ity where each species, no matter how small, all have an imp or tan t r ole to play. It is this combination that enables the ecosystem to possess the ability to prevent and recover from a variety of disasters.
Why is Biodiv ersi ty Importa nt? “At least 40 percent of the world’s economy and 80 percent of the needs of the poor are derived from biological resources. In addition, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change.” —

Massi ve Ext inct ions from Hum an Act ivity . (August 2, 1999) says that A report from Environment New Service “The current extinction rate is now approaching 1,000 times the background rate and may climb to 10,000 times the background rate during the next century, if present trends continue. At this rate, onethird to two-thirds of all species of plants, animals, and other organisms would be lost during the second half of the next century, a loss that would easily equal those of past extinctions.”
Threats on Biological Di vers ity In a slow extinction, various balancing mechanisms can develop. No one knows what will be the result of this extremely rapid extinction rate. . What is known, for sure, is that the world ecological system has been kept in balance through a very complex and multifacetted interaction between a huge number of species. This rapid extinction is therefore likely to precitate collapses of ecolosystems at a global scale. This is predicted to create large -s ca le a gric ul tural pr ob le ms, threatening food supplies to hundreds of millions of people.

Hab ita t Des truct ion
Most of the species extinctions from 1000 AD to 2000 AD are due to human activities, in particular destruction of plant . and animal habitats. While most of the species that are becoming extinct are not food species, their biomass is converted into human food when their habitat is transformed into pasture, cropland, and orchards. It is estimated that more than 40% of the Earth's biomass is tied up in only the few species that represent humans, livestock and crops.

In Papua New Guinea, 44 new species of animals were discovered recently in the forests. Logging may affect these animals' habitats, . though. The loss of rainforests around the world, where many species of life are found could be lost. Brazil which is estimated to have around 55,000 species of flora, amounting to some 22% of the world’s total and India which has about 46,000 and some 81,000 animal species (amounting to some 8% of the world’s biodiversity), are also under various pressures, from corporate globalization and deforestation. So too are many other biodiverse regions, such as Indonesia, parts of Africa, and other tropical regions.
