It is necessary to stress that about 40 percent of the pharmaceuticals used in the United States are based on chemicals synthesized from natural compounds found in plants and animals. About Biodiversity Coined by scientist Raymond Dasmann, the term biodiversity or biological diversity came to usage in the s. Some scientists use this term to pinpoint diversity in a smaller unit or level. In most science courses biodiversity is one of the usual topics discussed.
Many teachers prefer to discuss this not only because it gives you an idea on how our environment is capable of creating various life forms and at the same time, establish co-existence, but more so because of the pressing issues concerning biodiversity. A biodiversity essay , usually assigned in a science class, is one of the most interesting essay topics you can write about because its implications are visible in the environment, which we live in.
Biodiversity is a topic that anyone can relate to. Not only because we are included in the ecosystem, but also because considerable changes that has occurred recently and were caused by human intrusion.

Biodiversity essay font is an essential part of writing. Teachers say that Arial is the most readable font. That is why you can choose to use this one.
Sometimes students are asked to write with some other font. If you received no instructions concerning this matter, do not hesitate to use Times New Roman or Areal of 12th size. All the text should be double spaced. The writing must be printed only on white paper. It is not a good idea to leave too much space between the paragraphs.
There should be standard 1 inch margins. Proofread it several times. If you have any opportunity, ask your friend or parent to help you. Turn to the help of dictionaries and textbooks to be sure that you have conveyed the ideas by means of appropriate words and sentence structure. Do not forget to stick to word limit and be specific. Include the page with references. Number of habitats and ecosystems observed in an area is also a criterion for measuring biodiversity. Some important ecosystems are savarmas, rain forests, deserts, lakes, wetlands and oceans.
There is a much variety of fauna and flora in the oceans. India has a coastline of about 6, km. The main reason for this remarkable diversity of life forms in a single country is the great diversity of ecosystems, which it has supported down the ages.
Equally important are the micro-organisms like fungi and bacteria which are very important component of biosphere in as much as they are responsible for degradation of the dead biomass and release of nutrients, which are assimilable by plants and animals and enrich soil, as also form humus. Some noteworthy features of these regions are: About 33 per cent flowering plants, 53 per cent freshwater fish, 60 per cent amphibians, 36 per cent reptiles and 10 per cent mammals found in India are endemic.
Such areas include wetlands, lakes, oceans, tree canopy and soil of tropical rain forests. There is an urgent need to arrest species extinction. Equally important is the need to prevent the loss of thousands of years of human selection in crop species and domesticated animals for posterity. Biodiversity or its physical manifestation-the biological resources are the basis of life on earth. Ecosystem provides a variety of goods and other services- immediate as well as long term material which are vital to our well being.
Countries having greater biodiversity have better potential to compete with rest of the world in global market for search of genes and species with potential uses. The value of biodiversity in terms of its commercial utility, ecological services, social and aesthetic value is enormous. All the living organisms are so closely interlinked through food chain, food webs, material cycling, energy flow, etc.
Similarly, killing of carnivores will increase the population of herbivores which will damage the vegetation and disturb the ecological balance.
Species of plants and animals keep a check on their numbers through food chains, so the wildlife helps to preserve the environment as a self-sustaining system. Thus, ecosystems often support and provide services like soil fertility, plant pollinators, predators, decomposers, purification of air and water, management of flood and drought and other environmental disasters.
Biodiversity is required for maintaining and sustainable use of goods and services from ecosystems. These services are maintenance of gaseous composition in atmosphere, pollination, formation of soil, nutrient cycling, climate control by forests and oceanic systems.
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.
According to another report, rhino poaching in and around Kaziranga National Park has increased and 25 rhinos have been poached in In Orissa, many wildlife species including Asian elephant face imminent danger of extermination because of poaching and lack of concern by the Government to check trafficking of wild animals. Wildlife Society of Orissa has reported that 57 elephants have been shot dead by poachers for ivory between Strict action by Rajasthan Government coupled with quick judicial pronouncements in October, in the cases related to two black bucks by cine star Salman Khan and his accomplices has clearly sent a message that howsoever highly placed one might be, no one can escape the due process of law when it comes to the crime of killing the wild animals.
Introduction of exotic alien species are known to threaten the survival of many native species e. The fungus was accidentally introduced into the United States in It is a nuisance weed in many eutrophic nutrient rich lakes and rivers in tropical countries like India where it does not allow other plants to grow and multiply properly.
These exotic species are known to adversely affect the native species through factors like: Over-exploitation of natural resources e. Disturbance in migratory routes of animals like fishes due to construction of dams, etc. International trade in increasingly scarce animal products like medicines, perfumes, cosmetics, decoration, museum specimens, etc. A number of wild animals get confused and are run-over by the vehicles on the highways so decreasing their number.
Majority of Indian people are not aware of the importance of wildlife and ill effects of its destruction. So the people must be educated to save the wildlife. Large scale use of synthetic compounds release of radioactive chemicals, oil spills are polluting the rivers and reducing the species number. This leads to elimination of sensitive species and proliferation of tolerant organisms. Due to accumulation of pesticides, DDT, PCBs and dioxins, in Atlantic, decline in fish eating birds and wide spread deaths of seals has been observed.
Lead poisoning is also causing death of many wild life species.
() This essay will detail the findings of a policy risk assessment on a proposed management option put forward for the protection of the Border Ranges biodiversity that is “76%. private land”.
Biodiversity means the species of life on our mother earth and the ecological processes that support the diversity of ecosystems. The goal of this research paper is to understand the importance of biodiversity and the effects of deforestation on biodiversity.
Biodiversity is a key element in the earth's biosphere- the capability of earth and its atmosphere to support life- due to the earth's dependency on the maintenance of /5(7). "Biodiversity or biological diversity is the richness in species of all living micro and macro- organism's occurring in a given habitat." The word was coined in and during the s has become very widely used in the scientific circles.
Essays On Biodiversity Hand out: Biodiversity Biological Diversity or Biodiversity - is the variety (diversity) of all life forms on earth, encompassing all plants, animals, microorganisms and the intricate ecosystems they form. - the totality of ecosystems, species, and genes within the area. Levels of Biodiversity 1. Species Diversity (Different Life Forms) 2. Forest Biodiversity Loss Essays - 1. Introduction In many communities worldwide, people depend on forests, for fuel wood-gathering, harvesting of wood and non-wood forest products, for larger-scale commercial purposes, habitat for more than half the world’s terrestrial species, clean water, and other important ecosystem services (De Groot et al., , Santangeli et al., , Chhatre and Agrawal, .
