DESCRIPTION |
|
| Today, the nature and cause of problem is well recognized, and its gravity is well understood. Which the government searches for solutions, the people are learning to distinguish between the desire Powers and the physical Power of their natural resources. The diversity in life is called biodiversity. Usually, the measure of biodiversity is genetic diversity, a measure of how many distinct genetic species there are in tan area or population. These are sometimes called genetic resources, because they can be used as the stating point Biodiversity is used for new products or processes. Biodiversity is used in two contexts : the diversity of natural organisms, and the diversity of farmed crops or animals. Biodiversity concerns, In the larger world the vast range of plants (and animals, although these are considered less important from a biotechnological point of view) currently alive. Many of them may produce something useful to humans : a new drug, a new foodstuff, a new material. If they are allowed to be wiped out (and most species of plants live in the tropics, which are now under substantial threat) that potential will be lost for ever. There is substantial concern that the biodiversity of Third world (i.e. not rich) countries is being exploited by rich ones. Face many pressures the biodiversity in India i.e. forest, grasslands, wetlands Mountains, desert and marine ecosystems face may pressures, in over to expand agriculture one of the major causes for the loss of biological diversity in India has been the depletion of vegetative cover in over to expand agriculture. Biodiversity on the farm, is considered to be a good thing. If a country plants only one type of crop (as example), then a pathogen can sweep the entire country's crop from the fields Thus, not having a country plant just a single type (or cultivar) of a crop is protection against pandemics. In this the role of biotechnology is double-edged. If biodiversity produces a new, wonder-wheat, then that will be planted in place of all other cultivars, and the wheat-growing world will end up being a monoculture, biodiversity will have been reduced. By increasing the number crops with on the other hand, biotechnology methods are such that if we can transform one cereal with a gene you can transform a lot more, so biotechnology could actually increase biodiversity. By in increasing the number of crops with desirable genes in them. To grow monocultures of the most productive crop. The green revolution, including biotechnology, has been so successful that farmers are no longer under pressure. |
