2.3. NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY: Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution invasive exotic spices, diseases, shifting cultivation, poaching of wild life etc. Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its form and good health for the future generation
VALUES OF THE BIODIVERSITY Environmental value The environmental value of biodiversity is found by examining each ecosystem process and identifying the ecosystem services that cause it. For example, in wetlands the vegetation captures water-carried sediment and the soil organisms break down a range of nutrients and pollutants washed into the area. These processes provide the ecosystem the help of purifying water. Wetlands also act as spawning and nursery grounds for some fish and provide a refuge
Values of biodiversity Biodiversity is a gift that has been bestowed by nature upon all the inhabitants of this beautiful planet called Earth . The interdependence and inter linkage between all organisms of the ecosystem makes value of biodiversity indispensable in the life of humans and other organisms. Biodiversity provides twofold benefit to inhabitants of earth. Firstly, biodiversity is directly used as a source for food, fibre, fuel and other extractable resources. Secondly, biodiversity plays an
and ecosystem. Biodiversity is the variety and variability among living organisms from all sources, including terrestrial, marine, and other aquatic eco¬systems and the ecological complexes; this includes diversity within species, between species, and of ecosystems (CBD 1992). The term biodiversity, the short form of biological diversity, was coined by Walter G. Rosen in 1985. The fundamental to ecologically sustainable development is conservation and sustainable use of biodiversity. An environment
sometimes referred to as biodiversity (Wilson 1985). It differs from ecology in the sense that ecology is focused with interactions of individuals at a given time in a given area or space, whereas biodiversity is concerned with the diversification of lineages through time. The field of systematics involves two major components. Biosystematics and taxonomy, the discovery of the basic units of biodiversity, that is, different species. What follows from biosystematics and biodiversity is the reconstruction
Terrestrial protected areas (PAs) are considered to be an essential strategy for global biodiversity conservation. Nearly 12% of the world’s terrestrial surface is now classified as some sort of protected area. Globally, species richness is 10.6% higher and abundance 14.5% higher in samples that are taken inside protected areas than those which are taken outside. These results reinforce the importance of protected areas. However, protection does not consistently benefit species that have small ranges
I.Introduction Biodiversity is commonly defined as the variety of life and the variations within all species, including fauna and flora, as well as the multitude of ecosystems. Genetic diversity, species diversity and ecosystem diversity are three major layers of biodiversity. Biodiversity is often used as a measure of healthy, functioning and sustainable ecosystems from which we can obtain food, clean air and water and many other biological resources and social benefits .However, widespread destruction
Biodiversity is the variety of life on Earth and the essential interdependence of all living things . The diversity is important for evolution, and for maintaining the life-sustaining systems of the biosphere. The conservation and sustainable use of biological diversity are of critical importance to meet the food, health and other needs of the growing world population. The world needs to conserve biological diversity and make sustainable use of its components in a fair and equitable way. Sustainable
Biodiversity is the variety of life that is living in the ecosystem. The variety here can include the different species of animals, plants, or any organisms that live and interact with each other on the earth. Basically it is like a cycle of the living organisms which are dependent on each other for survival. Global warming is the condition of excessive emission of the harmful gases such as carbon dioxide, methane, chlorofluorocarbon and other pollutants to the atmosphere that can lead to the greenhouse
Abhay R. Joshi, “Wildlife conservation is the practice of protecting endangered plant and animal species and their habitats.” Wildlife conservation is one of the environmental programs which promotes sustainability in the planet as Joshi also stressed that “Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife and wilderness lands to humans.” Wildlife conservation is encouraged, advocated
