Biodiversity Essays & Research Papers

Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Greater biodiversity implies greater health. Biodiversity is in part a function of climate. In terrestrial habitats, tropical regions are typically rich whereas polar regions support fewer species. Rapid environmental changes typically cause extinctions. One estimate is that less than 1% of the species that have existed on Earth are...

Biodiversity From Wikipedia, the free encyclopedia Coral reefs are amongst the most diverse ecosystems on earth. Rainforests are an example of biodiversity on the planet and typically possess a great deal of species diversity. This is the Gambia River in Senegal's Niokolo-Koba National Park. Biodiversity is the degree of variation of life.[1] It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species...

Importance of Biodiversity Biodiversity can simply be defined as the variation of life at a given site or ecosystem. However, it is through this diversity that natural systems adapt, evolve, and thrive. Biodiversity increases ecosystem productivity; all of the species in that ecosystem, no matter their size, have a big role. A diverse ecosystem can prevent and recover from lots of disasters. Humans depend on plants and animals. For example, one quarter of all prescription medicines in the U.S....

Biodiversity is comprised of the totality of genes, species and ecosystems of a region. The occurrence of various kinds of flora and fauna in a region reflects its biological diversity or biodiversity. In most parts of the world which are habitable, the living world abounds in biodiversity. In a patch of forest, there is a wide variety of insects, animals, plants and trees. All plant and animal species cannot occur at one place. Whether or not a species can occur on a site is determined by...

Biodiversity: Who Cares? Biodiversity is important for many reasons. One reason it is important is for biological reasons. If biodiversity is affected in a biological community it can cause species to overpopulate or become extinct. These changes can cause issues with the goods and services that an ecosystem provides to humanity. Species’ functional characteristics influence the ecosystem properties. Every species depends on each other. If one is wiped out then another species will lose their...

The built environment has the potential to have a major impact on biodiversity, not least with the increasingly demanding requirements to design more energy efficient and airtight buildings, leaving less space for species to inhabit. Biodiversity under threat: There is much public concern about threats to global biodiversity. Industrial pollution, changes in agricultural practices and climate change, are all having a direct impact on biodiversity. In this book the Editors provide a broad view...

UNIQUE AND THREATENED BIODIVERSITY The patchwork of isolated islands, the tropical location of the country, and the once extensive areas of rainforest have resulted in high species diversity in some groups of organisms and a very high level of endemism. There are five major and at least five minor centers of endemism, ranging in size from Luzon, the largest island (103,000 km²), which, for example, has at least 31 endemic species of mammals, to tiny Camiguin Island (265 km²) speck of land...

Threats to Biodiversity Extinction is a natural event and, from a geological perspective, routine. We now know that most species that have ever lived have gone extinct. The average rate over the past 200 million years is 1-2 species per million species present per year. The average duration of a species is 1-10 million years (based on the last 200 million years). There have also been several episodes of mass extinction, when many taxa representing a wide array of life forms have gone...

 Biodiversity J.N.M Grade 10A HIS Ms. C.W Biodiversity is the biological variety or diversity of life on Earth (Anup). It is a connection between all organisms ("10 Surprising Threats to Biodiversity"); these organisms are all part of a “biologically diverse Earth.” Biodiversity enhances productivity in an ecosystem in which all species have an important role to play. Not only does it enhance productivity but also when it is conserved and healthy, it offers us...

Wednesday, 6 November 2013 Dear Mr Prime Minister Tony Abbott, I am writing to express my concern over inadequate preservation of biodiversity. Biodiversity is the variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable. According to Tim Flannery, between 1995 and 2008, the number of small mammals in Kakadu National Park declined by 75% and one third of the species that were recorded in 1995 can no...

Rachel Newell Walter Zeller International Relations November 18,2013 Loss of Biodiversity David Ehrenfeld says in his book Biodiversity “The value of biological diversity tells us a great deal about why biological diversity is in trouble”(212). People tend to over look the importance of biodiversity. Without it we would lose a lot of the resources that we use for important and everyday things. One example is that a lot of medicines come from plants, and the more plants we have on the...

Biodiversity Ecological Essay Biodiversity is the variety of plant and animal species. Biodiversity is very important to our ecosystem. The biodiversity of species can provide a variety of food such as meat, vegetables, and fruit. Most of our medicinal drugs come from plants. The periwinkle plant found in Madagascar, helps treat a lot of patients’ cancer. The yew tree also provides drugs that can fight cancer. Biodiversity is being threatened and we need to protect it. A boy named Jason...

Threats to Biodiversity: Habitat loss is mainly due to human population growth, industrialization and changes in the land use patterns, poaching of wild life and man wildlife conflicts. Man has begin to overuse or misuse most of these natural ecosystems. Due to unsustainable resource-use, once productive forests and grasslands have been turned into deserts and wastelands have increased all over world. Scientists have estimated that human activities are likely to eliminate approximately 10...

INTRODUCTION: Bangladesh is a gift of nature. It is gifted with much biodiversity of lives and an advanced ecosystem. Biodiversity was very rich in every sphere in our environment and ecosystem which was remained untouched and unharmed for centuries. But through- out years, population of Bangladesh has been growing in an unprecedented rate. With the growth of civilization, urbanization and industrialization had to take effect. As a result, from the 90’s decade Bangladesh had to walk in...

The value of Biodiversity Biodiversity has a fundamental value to humans because we are so dependent on it for our cultural, economic, and environmental well-being. Some argue that it is our moral responsibility to preserve the Earth's incredible diversity for the next generation. Others simply like knowing that nature's great diversity exists and that the opportunity to utilize it later, if need be, is secure. Scientists value biodiversity because it offers clues about natural systems that we...

story Life on Earth—The Importance of Biodiversity What is Biodiversity and Why Is It Threatened? April 20, 2009—Biodiversity is the variety of life on Earth. This includes all plants, animals and their habitats. As you can imagine, the Earth’s biodiversity is mind-bogglingly vast. According to the USA’s National Science Foundation (nsf.gov), 1.75 million species of organisms have been discovered and described, but scientists estimate that tens of millions are yet to be discovered....

Conservation of Biodiversity One of the most pressing environmental issues today is the conservation of biodiversity. Many factors threaten the world's biological heritage. The challenge is for nations, government agencies, organisations and individuals to protect and enhance biological diversity, while continuing to meet people's needs for natural resources. Biodiversity is the existence of a large number of different kinds of animals and plants which make a balanced environment. Biodiversity...

Describe Natural selection takes the raw material of variations with a population and moulds it over a long period of time into a population that can compete most effectively with other species. This selection will favor the fittest individuals in a species to fit a particular biological niche. Any given environment will have a large number of niches, for example small variations in the temperature, humidity and exposure to sunlight will affect the ability of certain plants to grow and...

Is Biodiversity Overprotected? What does biodiversity mean? It is a word used to describe the variety of all life in an ecosystem in addition to the specific habitats and communities in which they live (Convention on Biological Diversity). For years, people have been going back and forth on whether the environment is overprotected or underprotected. I believe that both sides of the debate go to unnecessary extremes, but agree with those who say that biodiversity is underprotected. The movement...

Biomes and Diversity Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? This is an interesting question. Lets consider the fact that it begins by stating extinction is a natural selection process. This seems to stifle one side of this argument.The side of the argument that rallies humans to be concerned with the extinction rate and strive to preserve a...

The Destruction of Biodiversity Why should you care? You should care, because there exists a chain to which all life is linked. Humans stand not apart, and there is no beginning or end. Extinction is like a trickling stream that grows to threaten riverbanks before drowning the world with oceans. We are foolish and naïve to assume that our creek can be maintained as we constantly introduce new species into foreign ecosystems, and destroy biodiversity with the detrimental effects of human...

The importance of biodiversity is being more widely recognized as increasing numbers of species come under threat. What can be done to maintain biodiversity? What caused by humans such as global warming, climate change, deforestation, environmental pollution,…engenders the loss of biodiversity. It is too big factor to ignore and requires immediately possible solution to preserve biodiversity. As a citizen of the globe, I put forward two ideas to halt biodiversity loss. Firstly, People...

The Loss of Biodiversity Brenda Peace POL310 Environmental Policies Instructor: Arthur Piervencenti February 10, 2013 It seems that in today’s time, the discussion of biodiversity and what it means is being discussed frequently. There are those who feel that biodiversity is something that will possibly take care of itself. Then there are those who realize that the Earth is changing and there are some things that need to be done to ensure that the Earth is preserved. This is going to...

Introduction Biodiversity also known as biological diversity is the existence of a wide variety of species (species diversity) or other taxa of plants, animals, and micro organisms in a natural community or habitat, or of communities within a particular environment (ecological diversity) or of a genetic variation within a specie (genetic diversity). (Oxford dictionary of biology). The root of concern for conserving biodiversity are increased loss of species, increased rates of deforestation and...

Declining Biodiversity Deanna Garrett ENV495 Jeanne Lambert May 6, 2013 Declining Biodiversity Biodiversity is important in ecosystems because every life form works together in order for them to function. When these ecosystems are disrupted or altered, or even lacks biodiversity, it poses major threats to all the life forms in it, whether it happens quickly or over a long period of time. These threats include atmospheric pollution, weather catastrophe, climate changes, or even man-made...

Philippine Biodiversity Biodiversity consists of variety of species, their genetic make-up, and the communities or population for which they belong. Therefore, Philippine Biodiversity is the variability among living organisms from all sources in the Philippines. * Endemic Species of the Philippines * An endemic species is one whose habitat is restricted to a particular area. The term could refer to an animal, a plant, a fungus, or even a microorganism. The definition differs from...

Conservation Of Wild Life forests Protection and conservation of forests and wildlife are essential to maintain the earth’s health and environment. The earth is the only known living planet and it is because of its special environment and ecology which are life-supporting. Forests are part and parcel of our environment. They are one of the most valuable resources and gifts of nature. They play a key role in the maintenance climate, rain-patterns, water and soil conservation. They are the...

BIODIVERSITY AND EXTINCTION Biodiversity is determined by the variety of species extant in a specific ecosystem; this includes both animals and plants. Biodiversity is what gives an ecosystem a continuing and symbiotic relationship between all the organic and inorganic elements; maintaining the proper balance of different gases such as nitrogen, oxygen, hydrogen, carbon dioxide and many other elements, which differ in composition depending on the type of environment (such as subterranean,...

‘Define Biodiversity and using examples, explain why it is important’ Biodiversity is the variety of life on earth. A fuller definition is given in the Convention on Biological Diversity (CBD) from the 1992 Earth summit: ‘Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part ; this includes diversity within species, between species and of ecosystems’ (Hambler, C.,...

As shown by the title, our earth’s biodiversity is at crisis. But some may wonder, what is biodiversity? Wikipedia tells us that biodiversity is the variation of life forms within a given ecosystem, biome, or on the entire Earth. Interesting enough, my science teacher was starting on the Biodiversity chapter when I spotted this poster. We learnt about the classification of species using their common characteristics, but I realize that there are always exceptions. For instance, we know that...

Tourism and biodiversity are closely intertwined. Millions of people travel each year to experience nature’s splendour. The income generated by sustainable tourism can provide important support for nature conservation, as well as for economic development. Furthermore, sustainable tourism can help to raise awareness among tourists and local communities of the importance of biodiversity to our everyday lives. Through initiatives such as its “Sustainable Tourism – Eliminating Poverty” project,...

Part 1 Components of Biodiversity | |Components of Biodiversity | Biodiversity classification | Number of species globally| | The total biodiversity of an area can be broken down into two hierarchical components:1) The number of functional types of organisms (e.g. carnivorous animals, Nitrogen (N)-fixing plants) or ecosystems (coniferous forest, prairie, tundra, marine intertidal).2) The number of functionally equivalent organisms/ genotypes within each functional type (e.g. the number of...

Biodiversity Essay Does encaging the animals in such places as zoo and aquarium be clarified as preserving biodiversity? There are two sides to this issue. Main points that support the idea of keeping the animals in cages that often come up are zoos are able to provide protection and they can increase the population of those species who are endangered (Hurley, J). Some important points that are against the idea of encaging the animals include the animals develop abnormal behaviours and they...

Meaning The definition of biodiversity encompasses the degree of variations in organisms and/ or species within an ecosystem. The loss of biodeversity would be the diminishing of dfferent species within that ecosystem. For example, a lake may be the home to many types of fish. A change in the lake's temperature or chemistry may affect a food source for a certain type of fish. This type of fish may die out and leave the lake with one less species in it. The loss of one fish or food source may...

Biodiversity is the part of nature which includes the difference in genes among the individuals of a species, the variety and richness of all the plant and animal species at different scales in space, locally in a region, in the country and the world and various types of ecosystems, both terrestrial and aquatic within a defined area. Biodiversity deals with the degree of nature’s variety in the biosphere. Types of biodiversity Genetic diversity - the genetic variability within a species....

Biodiversity is disappearing at an unprecedented rate. Worse, the trend appears to be accelerating, in spite of international commitments to reduce, or even halt, the rate of loss by 2010. Good systems of science governance capable of using biodiversity sustainably and equitably will be essential if we are to reverse the trend. UNESCO helps governments and policy-makers make informed decisions about biodiversity conservation within international efforts like the Convention on Biological...

_____Cameron Kashani_____, a review of: Spicer, John I. 2009. Biodiversity. New York: Rosen Pub Biodiversity and its decline is a subject often overlooked when talking about the dangers facing our planets ecosystem. A main reason for this seclusion is the vague nature of the word biodiversity. It is a term that has so many different meanings because of people’s different subjective interpretations. However at the Convention on Biological Diversity at Rio de Janeiro, Brazil in 1992, the term...

INTRODUCTION According to Oxford Dictionary, biodiversity means the state of having a large amount of different number of animals and plants which make a balanced environment. Biodiversity is also known as flora and fauna. The meaning of flora is all the plants growing in a particular area while fauna means all the animals of an area or a period of time. Rafflessia for flora while tiger for fauna is a case in point. Crisis on the other hand means a time of great danger or difficulty, the...

Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is one measure of the health of ecosystems. Life on Earth today consists of many millions of distinct biological species. The United Nations declared the year 2010 as the International Year of Biodiversity. Biodiversity is not consistent across the Earth. In the terrestrial context for example, tropical regions are typically rich whereas polar regions support fewer species....

English 101 May 6, 2013 Biodiversity Loss Biodiversity loss is a current issue that is affecting the environment around the entire world. Readings from groups like The World Conversation Union (WCU), The World Wild Life Fund (WFF) and The Millennium Ecosystem Assessment (MA) have information concerning the loss of diversity in living organisms like plants, insects, land and aquatic life. The groups mentioned study the loss of biodiversity loss in our environment and how it affects society and...

INTRODUCTION Biodiversity presents occurrence of variety of species and their natural community in which they live. By the definition it is “The degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. It is a measure of the health of ecosystems and is in part a function of climate.” (Rutherford) Ecosystem is on the other hand, “ community and its abiotic environment”( Rutherford). Biodiversity exists in every ecosystem, weather it is big one, or just...

 Biodiversity and population Size: Sumatran Tiger Biodiversity can be looked at in three different ways, genetic diversity, species diversity, and ecosystem diversity. Genetic diversity is the amount of variation occurs between or within a certain population. An example of what happens when genetic diversity does not occur is the Irish potato famine; all the potatoes had the same genes and when they became infected all died off. If they had different genetic variation some would have...

Britain’s Biodiversity Action Plans The meaning of biodiversity is all the variations of life, how they interact and how healthy they are. This includes all of the different species in the world and the ecosystems and how they interact with each other and survive. The countryside is rich in biodiversity because it contains many species of flora and fauna whilst it is lower within towns. Biodiversity is important to humans because these ecological systems provide us with resources like food,...

Animal, plant and marine biodiversity comprise the "natural capital" that keeps our ecosystems functional. Healthy ecosystems allow us to survive, get enough food to eat, and make a living. But the world is experiencing a dramatic loss of biodiversity.Although the pace of deforestation has slowed in globally since the 1990s, it remains high with annual deforestation of about 13 million hectares. The world has also lost about 40% of warm water coral reefs since the 1980s. The Living Planet...

 The variety and variability amongst environmental systems is the characteristic that enables sustainment in every day life. Commonly known as biological diversity, this distinctive feature encompasses the multitude of both plant and animal species that can be found in distinctive ecosystems across the globe. At the very least, diversity is accountable for the thorough development of all natural systems and warrants their existence. The inclination of biodiversity in our daily lives is what...

Proper utilization and management of nature and its resources is termed as conservation. International Union for conservation of Natural and Natural Resources (IUCN) define conservation as rational use of environment to provide a high quality of living for the mankind. Conservation is essential for life support system like air, water, land, flora & fauna, biodiversity and ecosystems. Natural resources are conserved due to economic as their natural beauty and importance to local culture....

Conservation is the protection and preservation of natural resources in the enviorment. the important renewable natural resources are air water soil wildlife and forests.

Chapter 2. Forest and Terrestrial Biodiversity of Mauritius 2.1 Overview of Biodiversity Mauritius has an area of 1,865 km2, of which 30% is considered forested. The area of good quality native forest, (i.e. that with more than 50% native plant cover, Page & d’Argent 1997), is estimated to cover less than 2% of the island (NEAP 1999, MWF unpublished, Fig.2.1). The rest consists of plantation forestry, deer-ranches or highly degraded vegetation invaded by alien plant and animal species. As a...

1. What is the importance of Biodiversity? * It is Biodiversity that allows animals, plants and humans to share our planet – if one species is destroyed, several may follow. * It is also important because certain organisms have economic value (such as forest plants being made into medicine), they have value to the ecosystem, and they are sources of natural beauty and recreation. * The biodiversity of both plant and plant species are core to the survival of life. * If loss of...

English 98 27 October 2011 Compare and Contrast Conserving biodiversity should be a major concern to all humanity on this planet. Biodiversity is what sets living organisms apart from each other, mainly the reason why we have so many species roaming our world. Beyond the immediate concern with the loss of a particular population, species, or ecosystem, a focus on long-term recovery and biological revival is also essential. Humans need to play conservation offense as well as...

ADVANTAGES OF BIODIVERSITY By adopting a different, more positive, and more proactive approach to the challenges that environmental issues pose, Indian enterprises will greatly benefit in this millennium. The prevalent attitude today, with some exceptions, is that environmental concerns impose costs that are best avoided. This is natural since these are costs which can fairly readily be externalised and imposed on somebody else. Thus, when industrial effluents render river water unfit for...

Why Preserve Biodiversity? ANSWERS 1. Define the term “biodiversity” Biodiversity, or biological diversity, is the term for the variety of life and the natural processes of which living things are a part. This includes the living organisms and the genetic differences between them and the communities in which they occur. The concept of biodiversity represents the ways that life is organized and interacts on our planet. 2. What is ecology? Ecology is the study of organisms and their relationship...

Bio Diversity and it’s loss in growth Biodiversity is the degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. Biodiversity is a measure of thehealth of ecosystems. Biodiversity is in part a function of climate.

How the plantation affect biodiversity? The positive impacts to biodiversity of plantation Trees used in plantations may have more conservation value than existing vegetation such as pasture, also it may improve downstream water quality and provide habitat for aquatic biota. Moreover, it will sequester carbon and hence contribute to mitigating or reducing climate change. The plantation may lead to reduced pressure on the harvest of rainforests elsewhere. Most importantly, Biopact (2008)...

There are currently 1.4 million described species on earth, but estimates of as many as 5 to 50 million total species have been projected to exist (Becher, 1998, 60). Tropical entomologist Terry Erwin’s research supports that there may be as many as 30 million insect species alone in the tropical rainforests (Shiva et al, 1991, 14). One of the true challenges to biodiversity is that there are so many species that we may be obliterating that we are not even aware exist yet. We are destroying...

"BIODIVERSITY" Biodiversity, as defined by E.O. Wilson, "is meant to be all inclusive- it's the genetic based variation of living organisms at all levels, from the variety of genes in populations of single species, through species, on up to the array of natural ecosystems." This includes plants, animals, insects, fungi, bacteria, and all microorganisms. All of these things create what is known as a web. These things interact with each other in some way there for they depend on one another...

There are several important ways in which humans can slow biodiversity loss, although there is no way to bring back the species that have already gone extinct. Protecting Areas Creating protected areas where human activity is limited is the best way to prevent deforestation and exploitation of organisms and the resources they need to survive. In order to truly make a difference, much planning needs to go into the creation of a protected area. It needs to consider all elements of the...

The title of there is “The Center of the marine shore fish diversity: The Philippine Island,” we have are the center of the marine in the world and the former Environment Secretary Elisea Gozun said in her presentation of the status of the country’s coastal and marine resources at the...

Climate change and tropical biodiversity: a new focus Brodie J., Post E., Laurance W. In this review article, Brodie et al. expose a different approach to looking at the effects of global climate change on tropical biodiversity. An abundant amount of literature does, in fact, address the direct effects of climate change on biodiversity in the tropics. Brodie et al. argue, however, that while these efforts are extremely important and notable for current and future conservation efforts, little...

• 1. In-Situ (natural home) • 2.Ex-Situ (artificial home) Actual Question in CSAT 2011 (12.) Which one of the following is not a site for in-situ method of conservation of flora? • (a.)Biosphere Reserve • (b.) Botanical Garden • (c.) National Park • (d.) Wildlife Sanctuary In-situ biodiversity conservation (Natural Home) • In this case, you identify an area with high biodiversity (= this area has lot of number and variety of plants and animals) • And then, you isolate and...

A GLOBAL SYNTHESIS REVEALS BIODIVERSITY LOSS AS A MAJOR DRIVER OF ECOSYSTEM CHANGE Species loss changes the most important processes of the ecosystem,productivity and sustainability.Biodiversity loss quickens this alteration of the ecosystem. It is researched whether species loss and the change of ecosystem or global enviromental changes have more effect on vital processes. Intermediate species loss reduces the plant production, higher loss has as detrimental impact as acidification, elevated...

4.3.1 State the arguments for preserving species and habitats. Why conserve biodiversity? The values of biodiversity can be classified as either direct values or indirect values (see pp.119-120 in the IB ESS Course Companion): • Direct values - can be (relatively) easily calculated • goods harvested & destroyed for consumption (eating) or sale in a market • generally physical commodities of some sort • private goods - value accrues to the owner of the resource •...

“A Decrease in Biodiversity: Should We Be Alarmed?” Submitted by: Mohand Abulaban Sebastian Gayosa I. Definition Biodiversity is defined in Wikipedia as the degree of variation of life forms within a given species, ecosystem, biome, or an entire planet. Because of this, the biodiversity of an ecosystem is a measure of that ecosystem’s health. Biodiversity is not evenly distributed; the biodiversity of one area of the globe may be completely different from that of another. The...

Linking Biodiversity, Ecosystem Services, and People What is Biodiversity and why is it important? Biodiversity is a term describing the variety of life, among living organisms and ecosystems. It refers to the wide variety of ecosystems and organisms suchs as animals, plants, their habitats, and the ecological complexes of the diversity within species. It is crucial for the functioning of ecosystems which provides us with products and services we cannot live without. Oxygen, food, fresh...

The Bio-geographic Classification for the Conservation of Biodiversity The Biogeographic Classification for the Conservation of Biodiversity are as follows: Biogeographic Zones of India: For the planning of conservation of biodiversity at the state and national levels, classifications of ecosystems are done based on biogeography. The biogeographical classification uses following four levels of planning: (1) The Biogeography Zone: It is a large distinctive unit of similar ecology, biome...

Around the world, forests are being logged for timber and paper pulp and cleared to grow mono-crops like soy and palm oil while they are deteriorating from the impacts of global warming. Deforestation is a major driver of global warming, responsible for up to 20 per cent of global greenhouse gas emissions–more than all the cars, trucks, planes, boats and trains in the world combined. Deforestation doesn’t just threaten our climate, it threatens the livelihoods of 1.6 Billion people that rely...
