Such services will otherwise cost 16 to 54 trillion 10 12 US dollars per year. Ecosystems with more biodiversity can withstand the environmental challenges in a better way because genetically variability leads to different tolerance range for a specific environmental stress. Due to this single stress cannot eliminate them easily; Thus species with higher genetic biodiversity have better adaptation ability towards environmental disturbances. Wildlife acts as a source of gene bank for breeding programmes in agriculture, animal husbandry, fisheries, etc.
Other wild animals are used as research materials on which drugs are tested before applying to mankind. Plant breeders have produced a number of high-yielding and disease-resistant varieties from their wild relatives by genetic modifications.
So there is an urgent need to protect wildlife for breeding experiments. The wildlife acts as a source for new varieties. The protection of wild life becomes of paramount importance for their survival and propagation of race, so man is constantly in search of ways and means of preserving natural areas in their natural conditions to promote the development of wildlife e. Similarly, wild rice Oryza nivara provided resistance against grassy stunt virus in s when virus- resistant gene was incorporated in IR rice variety; Wild Thatch Grass Saccharum sponataneum provided resistant gene to sugarcane against red rot disease; similarly in potato, resistant gene against late blight disease has been incorporated from a wild variety — Solarium demissum.
Thus the production of high-yielding, disease-resistant crops, livestocks and fish cannot withstand the changes of the surrounding without their wild relatives. Plants are also useful for making many synthetic products called botanochemicals. Twenty five per cent of drugs in pharmacy are got from only about species of plants. About seventy five per cent of anticancer drugs are derived from plants found in tropical rainforests. The medicinal benefits are not only limited to plant compounds.
A host of microbial, anti-viral, cardio active and neuro-physiologic substances have been derived from poisonous marine fauna. The venoms of various arthropods have medicinal potential. It is obtained from sources like livestock, forestry and fish.
Originally plants were consumed directly from wild habitats. Gradually, most of them were grown as agriculture. More than 80, species of plants are used as food. About 4, native plant and animal species are used by villagers in Indonesia for food and medicine.
Plants provide food not only for themselves but also for other organisms including man. Just three crops i.
Global fish production exceeds that of cattle, sheep, and poultry. It is the largest source of either world or domestic animal protein in the world. In fact, tourist industry of Kenya is based on its wildlife. Due to their beauty, many birds, variously colourful butterflies, mammals, green forests etc. Aesthetic pleasure derived from biodiversity includes bird watching, pet keeping, gardening, wild life sanctuaries etc.
Many plants are considered sacred and even worshipped in India e. Ficus religiosa peepal , Ocitnum sanctum Tulsi and Prosopis cineraria Khejiri. Many animals like birds and snakes are also worshipped. The value put to aesthetic function of nature is reflected in creation of millions of small home gardens, several community gardens, botanical gardens, zoos, aquariums established in different states.
Growing up in degraded environments, could result in the development of negative attitudes in human populations. A wild species may have certain benefits which are still not known to us and may become known in future.
So the conservation of even non-beneficial species is equally significant e. Wildlife is also important in games so are hunted upon while some of them are even worshipped. A visit to the sanctuaries and national parks is a thrilling experience. Some animals are used for recreation of people in circus shows.
The present wild life is the result of organic evolution which started about 3. So it is our ethical duty to conserve the wildlife for the utilization of coming generations. There are many animal gods as well like Matsya, Narsimha and Hanuman. It is a natural but slow process but due to unplanned activities of man, the rate of decline of wild life has been particularly rapid in the last one hundred years.
India alone has a total of threatened species of which include 86 mammals, 70 birds, 25 reptiles, 3 amphibians, 8 fishes, 23 invertebrates and plants. The biological diversity of ecosystems like Wayanad, Kolli Hills, Jeypore Tract, Bhitarkanika, Lakshadweep Islands, Arunachal Pradesh and Mizoram is under threat because of conflict between food security of population living therein and biodiversity conservation.
Main causes of its facing extinction are increasing destruction of its habitat, by deforestation coupled with jhum and shifting cultivation. Dams block spawning and migration of certain fishes. Due to this species present in deeper areas start disappearing. The declaration of common Hippopotamus Hippopotamus amphibius as endangered species in Redlist is primarily due to habitat loss and its over exploitation for meat and ivory.
Animals like elephants, lions, bears and large cats require bigger areas to survive and more. Few birds can reproduce only in deep forests. Indiscriminate hunting for various uses of animals like food, hide, musk, tusk, horn, fur, plumage, recreation, etc.
Other causes of indiscriminate hunting of wild animals are: Excessive hunting is known to cause. Last live cheetah died in Delhi Zoo in According to a report of WPSI Wildlife Protection Society of India , more than 60 tigers have been poached in different parts of the country during the year A London based international conservation organisation has stated that poaching of tigers for Chinese medicines, is responsible for the death of at least one tiger in India every day.

The aim of this study will be handing out a wide-ranging presentation of the present stance of ASEAN and its accomplishments till date, along with its challenges. The paper is intended as a suggestion for a master-plan that can be employed as a future pathway where ASEAN political-security support must be going towards in the forthcoming years.
To start with let us have a brief introduction of the organization. The creators of the Association of South East Asian Nations - ASEAN, visualized it as ultimately assembling all the nations of the region and managing them to lend a hand in assuring the peace, permanence and growth of the area.
While the area was in a state of turmoil, a lot of nations were under pressure for the existence of the nation or autonomy. Urban Drainage System Sustainable Urban. If there is an aggregate sub-base, these can provide water quality treatment. There should be good compaction and appropriate geo-textiles especially for areas accessible to heavy vehicles.
Permeable pavements reduce the need for deep excavations thereby providing a cost benefit. This system reduces the run-off rates and peak flow. The overall benefit is that it removes pollutants and holds water so that it does enter the main drainage. A lot of water in the main drainage would either need pumping or treating thereby using energy Wild et al.
Swales They are continuous vegetated drainage systems which convey or store water while allowing filtration when appropriate. Usually, they are the equivalent of roadside gullies or drainage pipes in conventional drainage systems. However, swales have gentle gradient so that water moves at low velocity. The sediments in storm water run-off can, therefore, settle out.
The advantage of swales is that…… [Read More].

Extinction Events or Environmental Catastrophes Many uncertainties exist over the acts and roles of extinction in the world today. Nonetheless, with all these uncertainties, it is possible to formulate reasonable statements that depict the probable role of extinction.
The role of extinction can be thought to have some elements, most of which are instrumental in striking the relationship and power seen in evolution and extinction in the earth's history up to the appearance of hominids 8 million years ago. For any widespread species or any group of a widespread species, extinction needs some bit of environmental shock that comes in the form of physical or biological aspects that normally occur.
Such occurrences take place during the geological lifespans of the given species or groups of species.
In this case, the shock that is resulting has to be applied with a rapidness that is enough to take place over a…… [Read More]. According to Branch et al.

Since them the severity and frequency of bleaching events continues to increase.
These bleaching events correlate with rising average sea temperatures on a global basis, rising sea levels, and more frequent tropical storms fueled by increasingly stronger heat masses U. In addition to coral reef bleaching, the geographic ranges of many plants and animals are shifting. Plant and animal ranges are generally limited by climatic factors, with animals able to respond to climate changes faster than plants due to increased mobility EPA, Ecosystems and Biodiversity.
