The Loss of Biodiversity on the Ecosystems
A person’s health and welfare is subject to ecosystem benefits supplied by natural surroundings, such as the purification air and water, fisheries, woodlands, and nutrient recycling. These are principally commodities with no retails as well as no prices, hence their depletion frequently is not sensed by new economic money methods and may thus endure unrestricted. Resulting in a variety of pressures from population growth to climate change that causes biodiversity to deteriorate, and ecosystems are ceaselessly being defiled (EPA, 2011). Therefore, protecting biodiversity is essential to aiding and safeguarding the existence of many species in diverse ecosystems and everyone’s health and welfare.
Biodiversity depletion is driving ecological components nearer to a critical point where the situation leads to a new and irreversible development, from which they may never be capable of fulfilling their fundamental and important purposes again (EPA, 2011). The infinite preponderance of research of climate effects on different native collections expose dependable answers to global warming developments, including shifts of plants, animals, and people. Responses of native animals to the warming across the earth are thoroughly acknowledged by alterations in the timing of growth in plants, characteristically the early onset of spring, bird migration, and expansion of the growing period. This is because the ecosystem is a symbiotic, operating system of vegetation, wildlife, and microbes and may be as the desert, or as small as a small creek. Moreover, when one fundamental species is gone the life of the other entities within their own ecosystem would not live on or even thrive. Ecosystems support s...

... species and supplies an economical method for concurrent preservation and recovery of an assortment of species. Even though species by species method however tremendously consequential to our endeavors of preserving biodiversity is ineffective (Graz, 2004).
While humankind develops, a new understanding of the proof that whole ecosystems and collections of species are in the declined and protecting special animals under the Endangered Species Act will not resolve all preservation difficulties. Furthermore, it will not essentially avert the requirement for imminent listings on the E.S.A; the justification of ecosystem preservation grows to be more compelling (Noss, LaRoe, & Scott, 2003). Proving that protecting biodiversity is essential, by aiding and safeguarding the existence of many species in diverse ecosystems, it will benefit everyone’s health and welfare.
The preservation of any species that contributes to the biodiversity of an area. In an ecosystem, the absence of one species creates unfavorable conditions for the others. The. The absence of the spotted owl could have a significant effect on the North Coast forest ecosystems. In order to send the owl population to the right.
Global warming has taken planet earth by storm. Over 1 million animal species have gone extinct, and many more are predicted to follow. In the past century, temperatures have increased 1.4 degrees Fahrenheit due to humans’ high outpouring of greenhouse gases. This change has resulted in rising sea levels, which leads to habitat loss and climate change. This affects not only animals, but human beings, as well. If we don’t start an effort to save this plant, who knows how long it will last. Earth is a Marvelous place that’s a privilege to call home; it’s about time we start treating it that way.
The Endangered Species Act Introduction: Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65). As a result governmental and societal action must be taken immediately!
are at a very high risk of extinction. There are over 3000 endangered species around the world due to many factors including over-fishing, hunting, destruction of habitat, climate change and a decrease in food supply. As the number of endangered species are increasing quickly it is very important that action is taken to preserve them for a number of reasons. If endangered species are not preserved it could easily lead to the species becoming extinct which could upset the food chain and lead to further extinction of other species. This could have not only negative effects on there predators but would eventually lead to having negative effects on species further up the food chain including the human species. Over the years researches have come to discover and find that all species play an important part in looking after our ecosystem and extinction could cause a big hole in the system.
The Convention on Biological Diversity (hereafter: “CBD”) is an international treaty adopted by United Nations Conference on Environment and Development, held at Rio de Janeiro in June 1992 and came into force on December 29, 1993. Initially when it came into force there were 168 members now it is 193 in total. The aim to protect biodiversity and the dramatic steps taken for conservation, sustainable use and the fair and equitable sharing of benefits attracted the world communities to become members (History of the Convention, n.d). In principle the convention on biological diversity changed the ownership concept of biodiversity protection i.e. (“common heritage of humankind”) to the “sovereign right” of each member country (Hirsch, 2012). It is the responsibility of the each member to develop and implement policies in a way that helps in the conservation and sustainable use of biological resources. It also recognizes the knowledge of local and indigenous people for conservation and sustainable use of biodiversity (Brahmi et al., 2004).The article 8(j) of CBD has an important provision which gives the member state rights to “respect, preserve and maintain” traditional style and knowledge about the conservation and sustainable use of biological diversity. The protection must promote the wider application of such knowledge and stimulate innovation and also ensure that the benefits are shared in fair and equitable manner to the communities.

I would argue that at the very least, there needs to be some form of triage implemented. The way the Endangered Species Act is currently allocating funds is mediocre at best and has many flaws. There is no denying there are limited resources so that makes efficient use of them even more important. Each of the systems of triage outlined in this paper have valid points and problematic components. Elements of each system could be combined into a nicely working plan that recovers the greatest number of species on a limited budget.

Having considered both sides of the argument surrounding the Endangered Species Act, it seems logical to conclude that, despite the fact that they Endangered Species Act could stand some improvement in terms of the speed of the bureaucracy that governs it, the Act itself is quite sufficient as is as long as it is administered to the full extent of its power. There is a growing tendency in government, however, to undermine the strength of the Endangered Species Act by making decisions on when and where to apply it a political matter rather than an ecological matter (Munro, 2010). To do this is to insure that ultimately it will not just be the environment and the wile organisms that live in it that will lose, it will be mankind as well.
Thousands of species have become extinct over the last four decades as a result of changes in land use and as a result of global warming. Whether or not the millions of species can adapt and evolve to climate changes is debatable. As this brief overview will report, the human species is not adapting well to the changes. It must be remembered that increases in the levels of carbon dioxide are certainly responsible for the risk many species face, but so is the way land is used, e.g., rain forest destruction. There is a feedback loop wherein plant life and the climate are interdependent. Each affects the other. When forests are cut down, temperatures in that area will rise. Rising temperatures cause other plant life requiring cooler temperatures To die off.
Climate Change is any substantial change in climate that lasts for an extended period of time. One contributor to current climate change is global warming, which is an increase in Earth’s average temperature. Plants and animal species throughout the world are being affected by rising temperatures. Many plants are flowering earlier now than they once did; animals, such as the yellowbellied marmot, are emerging from hibernation earlier; and many bird and butterfly species are migrating north and breeding earlier in the spring than they did a few decades ago, all because of slight changes in temperature cues. (Shuster)
In many parts of the world, ecosystems’ temperatures begin to rise and fall to extreme levels making it very difficult for animals and plants to adapt in time to survive. Climate has never been stable here on Earth. Climate is an important environmental influence on ecosystems. Climate changes the impacts of climate change, and affects ecosystems in a variety of ways. For instance, warming could force species to migrate to higher latitudes or higher elevations where temperatures are more conducive to their survival. Similarly, as sea level rises, saltwater intrusion into a freshwater sys...
Economic valuation is an important component of environmental policy, although it is difficult to affix a cost on the environment and ecosystem services, it is a measurement that is relevant to most in society humans. Therefore, economic tools may be useful in reinforcing the importance of maintaining biodiversity and preserving fragile ecosystems.
Nowadays it is common to read articles in newspapers and magazines regarding biodiversity issues. Human beings have been knowingly and unknowingly destroying biodiversity since their existence. Biodiversity is the measure of the variety of species of animals living in an area. Forests are usually areas with high biodiversity while deserts are the opposite. Human beings have always destroyed biodiversity either by deforestation, or by some other means. Biodiversity depletion is a natural phenomenon. But the present levels of biodiversity depletion are many times higher than the natural rate. Recently the levels of loss in biodiversity have started causing global concern. Some of the main causes for loss in biodiversity are alteration of habitats, increasing levels of pollution and human population growth.
The Earth is far and away the most biodiverse planet in our solar system, with about 8.7 million more unique species than the other 8 planets (UNEP). However, the Earth’s commanding lead is shrinking; not because the other planets are increasing biodiversity, but because Earth’s is decreasing. According to the World Wildlife Fund, we as a planet are losing 1,000 to 10,000 more species than the natural rate. Since the total number of species is hard to pin down, this can mean anywhere from 200 to 10,000 species going extinct per year (World Wildlife Fund). This obscenely high extinction rate is dangerous not just to ecosystems directly affected by the loss, but also creates a domino effect that circles around the globe and up and down the food
