...Lack of bio-diversity appears to impact environments as much as worldwide heating, contamination and other significant types of ecological stress, according to results of a new study by a worldwide research team. The research determines that reduced bio-diversity impacts environments at levels much like those of climatic change and air contamination. Some people have presumed that bio-diversity results are relatively minimal compared to other ecological stresses. Studies over the last two years confirmed that more naturally different environments are more effective. As a outcome, there has been growing concern that the very high rates of modern extinctions due to environment reduction, overharvesting and other human-caused ecological changes could reduce natural ability to provide products or services such as food, water that is clean and a constant environment. Until now, it's been uncertain how bio-diversity failures collection up against other human-caused ecological changes that impact environment health and efficiency. Lack of scientific variety due to varieties extinctions is going to have significant results in the world, and we need to prepare ourselves to deal with them. This global synthesis found that in areas where local varieties reduction during this millennium drops within the lower range of forecasts losses of 1 to 20 percent of place species, minimal results on environment place growth will outcome, and changes in varieties wealth will position low comparative...

...State of Philippine Biodiversity Photo Credits (L-R): Philippine Eagle (Klaus Nigge/National Geographic); Hoya melliflua (Leonardo Co); Mts. Iglit-Baco (PAWB); Platymantis polillensis (GTZ-DENR) The Philippines is a treasure trove of biodiversity or the variety of life on earth. It is believed to harbor more diversity of life than any other country on earth on a per hectare basis. It is in fact one of the 17 megadiverse countries which host 70-80% of the world’s biodiversity. Yet, Philippine biodiversity is alarmingly endangered, making it a biodiversity hotspot as well. As a paradise of biodiversity, the country’s terrestrial ecosystems are home to many of the best and rarest wildlife species. It has more than 52,177 described species, half of which are endemic or found nowhere else on earth. There are more than 1,130 terrestrial wildlife species recorded for the Philippines (49 percent or half are endemic); 157 are threatened (128 are threatened endemic). Floral diversity is just as extraordinary, with between 10,000 and 14,000 species of vascular and non-vascular plants, more than half of which are endemic to the Philippines. Altogether, the country is host to some 5 percent of the world’s species of flora and is ranked 5th in the world in terms of number of plant species. The archipelago is also now recognized as one of the most important centers of amphibian and reptile diversity in Southeast Asia. An estimated total of 359 species of amphibians (101 species) and reptiles...

...Decline in Biodiversity Deanna Garrett ENV497 Chad Goings July 15, 2013 Decline in 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. When we lack biodiversity, our ecosystems become unstable, which in turn makes them more vulnerable to disasters and they cannot contribute to our well being. Although policy makers may be faced with challenges, many considerations need to be taken into account to preserve biodiversity and to protect these areas so that these ecosystems can function properly and prosper. When we hear the word ‘biodiversity’, it pretty much explains itself. It is the amount of variation of life forms within a given biome, ecosystem, species, or even the entire plant. Many considerations need to be taken into account to preserve biodiversity and to protect these areas so that these ecosystems can function properly and prosper. With respect to the ecosystem and biodiversity, we need to remember that once our natural resources run out and when most ecosystems are destroyed, it is very hard to restore it to what it was. We need to consider our well being, as well as all the other organisms that we share the earth with. We use biodiversity all the time, whether it is direct or indirect. In order for us to...

...Abstract The diversification of human induced disturbances upon natural ecosystems has contributed to wildlife habitat fragmentation which has been a serious threat to the survival of natural populations. Possible factors contributing to this decline include changes in food, loss of genetic variation, cover availability, evolution of predation, microclimatic effect, and lack of recolonization following extinctions. Habitat loss and fragmentation are processes that separate small populations, which have higher extinction rates that may lead to a reduction in biological diversity. Recent dramatic declines in forest management have brought some undesirable consequences for forest health and wildlife (Jack Ward, T. (n.d). Standing back and letting nature take its course has become increasingly prevalent. Unfortunately, while appealing as this sounds, this is not tenable in the long-term as it will not protect forests, retain biodiversity, and provide some wood products over time. We are increasingly depending on places beyond our borders to provide our wood places with far less resources and knowledge about how to manage forests responsibly. By importing wood products, we export not only environmental consequences but jobs and dollars ( Jack Ward, T. (n.d). Conservation biology needs to reach out to a much broader community of academics and practitioners in fields as diverse as anthropology, history, political geography, and environmental psychology (Bernstein...

...Ayla Reau TSEA per.3 May 17, 2010 It is a sad day indeed when your children might never see a live polar bear in the Arctic or an orangutan swinging through the forest of Borneo. The only place future generations will have a chance to possibly see these endangered animals will be in pictures and zoos, since we humans are now causing the greatest mass extinction of species since the extinction of the dinosaurs 65 million years ago. In the last two centuries alone the Earth has witnessed world-wide accelerated rates of animal extinction and endangerment, which has taken place alongside industrial progress and rapid human population growth (“Animal Extinction”). So just what is an endangered animal and why should we care? A broad definition is an endangered animal is a species that is threatened with extinction. The extinction of a species is a catastrophic event that impacts the whole planet and its inhabitants including humans, as all life on Earth is interconnected. Therefore, humans should attempt to conserve the natural habitats of the Earth and in turn the animals that live in them. However, that is not the reality, for humans are one of the main causes of animal extinction and endangerment. As Julia Marton-Lefevre, IUCN's Director General said, “hundreds of species could be lost as a result of our own actions”(in Goodman). In the entire Earth’s history there has only been five great mass extinctions, we are now in the midst of the sixth great mass extinction, driven...

...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 extant.[1] Biodiversity biodiversity is divided into three, phenotypic, genoti, environmental Ecological diversity refers to the sum of the different types of environment or Ecosystem present in a region or the habitat which is the sum total of the climate, vegetation and geography of a region. Ecosystem is a unit of the biosphere in which there is an interaction between the living and nonliving factors so as to maintain a continuous flow of energy. It is a structural and functional unit of a biosphere. There are several kinds of habitats or ecosystems around the world. The variety of diversity of species in an ecosystem is influenced by the ecosystem it self. Examples of ecosystems: Grass land, wet land, desert, aquatic ecosystem etc. Species diversity is the variety of different species in a given area. It is very difficult to estimate the different species in a given area. Most of the species are found near the equator and a few at the poles. Genetic Diversity may be defined...

...relationship between biodiversity and employment, which are found to differ between the EU and developing world. In the EU, employment related to biodiversity often provides new and skilled employment opportunities for a population increasingly disconnected from the land. In developing economies, however, much of the employment linked to biodiversity is in poor quality, low paid subsistence jobs in the primary industries. Nevertheless, more sustainable farming and forestry practices offer potential both to maintain biodiversity and to enhance employment by supporting safer, more lasting jobs linked to local livelihoods rather than centralised systems of production. Nature conservation and ecotourism also offer opportunities for skilled, knowledge-based and sometimes relatively well paid employment, often helping to diversify local economies and the employment opportunities they provide. The connection between biodiversity, ecosystem services and jobs There is a lack of knowledge about the point (thresholds) at which changes in biodiversity will impact ecosystem services to such a degree that economic activity and jobs can no longer be sustained. The vulnerability of ecosystem services to changes in biodiversity varies considerably depending on the spatial scale, the type of ecosystem service, and the aspect of biodiversity being considered. For certain ecosystems, such as coral reefs, mangroves, or tropical forests, small changes in biodiversity The Social Dimension...

...The Sixth Extinction: An Unnatural History details the continued loss of biodiversity that has occurred since the rise of mankind. Elizabeth Kolbert claims that we are now in the midst of a sixth mass extinction, and that, if precautionary measures are not taken, the loss of biodiversity would be catastrophic. Chapter one begins by describing the golden frogs in the town of El Valle de Antón, and how they were beginning to disappear. The frogs disappeared due to a fungus called Batrachochytrium dendrobatidis. This fungus has spread around the world at a lightning-quick rate, killing all sorts of amphibious organisms at an unnatural rate. The cause of the rapid spreading of the fungus has been theorized to be due to humans inadvertently spreading...

...An environmental issue Course title Course instructor Name Date Introduction Bio means life while diversity means variation in the various aspects of things. Biodiversity entails the extent of variation of forms of life within a given planet or species. The number of plants’ species, microorganisms, the great diversity of species’ genes, animals, the various planets’ ecosystem such as deserts and coral reefs forms part of biodiversity on earth. However politics and power have greatly influenced the shaky balance. There has been a great biodiversity loss since the human race emerged. (Miller, D. A. 2008 p.23) Biodiversity has as well affected cultural diversities and thus should be keenly dealt with. This ranges from the various types of traditional foods used by the various societies. Biodiversity loss is rendering them extinct. Physical Elements of Biodiversity Loss In the physical reality much can be read on biodiversity loss. For example, the emergence of new breeds of animals and plants can be seen being developed in any other corner of the world. People are keenly trying out new breeds as a means of curbing food shortage. For example, the genetically modified food has been termed as a way of reducing food shortages. This has impacted negatively to human health. Population decline of species, a research done in UK in 2008 clearly revealed that the population of bats was...

...What is biodiversity? Why does it change? Why is it important to conserve it? INTRODUCTION Presently these days, lots of people live in urban areas. In this case they are separated from the environment. But another important reason why humans will always depend on the environment is because our lives depend on biodiversity. Meaning that we get clothing, medicines, food and furniture from other species. Just because that people rely on biodiversity they have to conserve biodiversity and can save it for future generations (www.scienceclarified.com). But before knowing all the damage this can cause to us, firstly we should know what biodiversity is. Why does it change? Why we have to conserve biodiversity? The aim of this essay is to answer these three questions, so in this paper I will try analyze most important things about biodiversity. MAIN ARGUMENTS The definition of biodiversity has many different connotations, description of species composition interactions between organisms and their environment (Orians, G. H. 1996, p.49). But the major definition of biodiversity is: the variety of life in all its manifestations (Lecture notes). This modern definition can sound like the variety of life on earth, variety of species, and the communities in which they occur. The major elements of diversity are: genetic, taxonomic, and ecological. The first one is Genetic (populations, individuals) – individuals of the same species. It means genetic variations between individuals...

...Sustainable forest management requires three major criteria which are the maintenance of ecological processes within the forest (soil formation, energy flow, biogeochemical cycles (carbon, nutrient and hydrological cycles), maintenance of biodiversity of forest, improving the net social benefits derived from the mixture of forest uses within the constraints by considering the future. Forest provides habitats for more than half of the fauna and flora on the Earth (SCBD, 2001). Forest biome plays an important role in mitigating climate change by serving as carbon sinks (Hassan et al., 2005). Forest land is the most fundamental natural resources which become reduced mainly due to anthropogenic pressures. For proper management of land, it is essential to have information about existing land cover and about the naturalness of the land. The increment in forest cover does not mean that...

...Do threats to biodiversity pose the greatest challenge to humanity for the 21st century? Introduction: The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. Biodiversity includes not only special we consider rare, threatened, or endangered, but every living thing even organisms we still know little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well as those in distant lands all play a role in maintaining healthy ecosystems. Biodiversity is important because it boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, a larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. There are five main threats to biodiversity that I can cover later on in this report are: 1. Invasive alien species 2. Climate change 3. Nutrient loading 4. Water pollution 5. Loss of habitat 6. Overexploitation In this report my goal is to explain what biodiversity is in detail in depth and explain how important it is to the world. Also, to outline if and how these threats pose a threat to humanity in the 21st century. How important is biodiversity? Biodiversity is important for all species' survival. We need a variety of habitats for...

While they appear to prefer small mammals, they also eat birds, reptiles and amphibians. What government do to preserved biodiversity? There are several ways the governments can do to preserve biodiversity, such as: 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 ecosystem it is trying to protect, so that it isn’t too small. It needs to include all resources that are utilized by its inhabitants; for example, leaving out a stream where half of the mammals go to drink would not make...
