                    ways to save water :

healthy ecosystem are the base for a wide range of economic , environmental, and aesthetic goods and services. the products of ecosystem processes are named as ecosystem services. for example , healthy forest ecosystem purify air and water . mitigate droughts and floods , cycle nutrients , generate fertile soils , provide wildlife habitats , maintain biodiversity, pollinate crops, provide storage site for carbon and also provide aesthetic, cultural and spiritual values. researcher have put an average price tag of us $ 33 trillion a year on these fundamental ecosystem services, which are largely taken for granted because they are free. this is nearly twice the value of the global gross national product gnp which is ( us $ 18 triilion ). out    of  the total cost of various ecosystem services, the soil formation accounts for about 50 percent and contribution of other service like recreation and nutrient cycling , are less than 10 percent each. the cost of climate regulation and h

we conserve the biodiversity by 2 methods . these methods are   in site conservation. ex site conservation .

from a study of the history of life on earth through fossils records, we learn that large scale loss of species like the one we are currently witnessing have also happened earlier , even before humans appeared on the scene. in general , loos of diversity may lead to decline in plant production  lowered resistance to environmental perturbation such as drought. increases variability in certain ecosystem processes such as pkant productivity , water use and pest and diseases cycles. the major causes of biodiversity are habitat loss and fragmentation :  this is the most important causes driving animals and plants to extinction . one covering more than than 14 percent of the earth land surface . these rain forest now cover no more than 6 percent . they are being destroyed fast. besides total loss, the degradation of many habitats by pollution also threatens the survival of many species. when large habitats are broken up in to small fragments due to various human activities

there are many reason .some obvious and others not so obvious , but all equally important . these can be grouped into three categories  narrowly utilitarian. broadly utilitarian. ethical utilitarian. narrowly utilitarian :  arguments for conserving biodiversity are obvious. humans derive countless direct economic benefits from nature food ( cereals,pulses, fruits ), firewood , fibre, construction material, industrial products ( tannis, lubricants,dyes,resins,perfumes) and products of medicinal importance. more than 25 percent of the drugs currently sold in market worldwide are derived from plants and 25000 species of plants contribute to the traditional medicine used by native people around the world. the broadly utilitarian :  arguments says that biodiversity plays a major role in many ecosystem services that nature provides . pollination is another service .ecosystem provide through pollinators layers bees,bumblebees,birds and bats. the ethical utilitarian :  arguments f
