#1
One of the strengths of ecological restoration as a landscape management practice is that, its capacity to engage people from all sectors of the community. Ecologically and socioeconomically, restoration is a practice that accelerates recovery of a damaged or degraded ecosystem, and therefore recovery of ecosystem services. Culturally, ecological restoration promises to renew the human relationship with nature. Traditionally ecological restoration emphasizes on goals that rejuvenate sites to its prior historical conditions, or its natural state. The concluding goal of ecological restoration is a sustainable healthy functioning site, whether that includes the site returning to its historical structure and composition or not. In recent times,

132). Based on that definition, sustainability theorists and philosophers have disagreed about what kinds of moral obligations we might have to future generations. Some advocate for weak sustainability, whereas, others advocate for strong sustainability.‘Weak’ sustainability is fundamentally anthropocentric oriented, with social equity and environmental protection regarded as less than to sustainable economic growth. Often, the focus is on constructing more efficient supplies in economies by including ‘ecosystem services’ into the market. ‘Strong’ sustainability, on the other hand, reverses the order of priority and gives antecedence to ecological scale over economic efficiency. Social equity, is best achieved by restoring ecosystem health, recognizing ecological tipping points and cultivating system resilience. New economic indicators of wellbeing and quality of life are advocated and market based solutions that impose monetary values on life and “ecosystem services” are rejected on moral grounds. The key idea of ‘weak’ sustainability suggests that natural capital and other types of capitals are perfectly substitutable. The key idea of ‘strong’ sustainability is that, the substitutability of natural capital by other types …show more content…
Defenders of restoration, like myself, have insisted that humans can engage positively with nature in a constructive partnership that allows us to fulfill our moral obligation to correct damage that we have inflicted and to restore natural value. I agree with philosopher Andrew Light who has argued against ecological restoration being a “big lie”. Light has argued that there are different types of restoration, and we can distinguish between them. There are malicious and benevolent; malicious restorations are those that help to rationalize ongoing ecological damage. Benevolent restorations are those undertaken to remedy a past harm to nature without attempting to justify or rationalize such harm. (p.186 Hourdequin) I believe that restored nature can be of equal or greater value than undisturbed nature. Take a nature site that has been undisturbed, it is possible that this location can have invasive species with no natural enemies to limited their reproduction. Hypothetically, if restoration were to occur at this site, measures to fix an invasive species, like ivy, then the results of the restoration will be better. The restoration would be better for the rest of the species within that area compared to when it was undisturbed. Andrew Light also suggest
ABSTRACT: Robert Elliot's "Faking Nature," (1) represents one of the strongest philosophical rejections of the ground of restoration ecology ever offered. Here, and in a succession of papers defending the original essay, Elliot argued that ecological restoration was akin to art forgery. Just as a copied art work could not reproduce the value of the original, restored nature could not reproduce the value of nature. I reject Elliot's art forgery analogy, and argue that his paper provides grounds for distinguishing between two forms of restoration that must be given separate normative consideration: (1) malicious restorations, those undertaken as a means of justifying harm to nature, and (2) benevolent restorations, or, those which are akin to art restorations and which cannot serve as justifications for the conditions which would warrant their engagement. This argument will require an investigation of Mark Sagoff's arguments concerning the normative status of art restorations.
Time and time again it has been seen that human interaction with his/her environment and it’s ecosystems has shown to be increasingly arrogant and self-serving. These endless accounts are proven by the amount of important biological diversity that is being lost to the surrounding environment due to these threats of human development and population growth. There are two forms of these losses of diversity by human hand: direct and indirect. Direct losses would be the destruction of an area needed for human requirements be it social or economical. Examples of these losses would be housing, agriculture, and others. Indirect losses would be those caused by the destruction of an area also needed for the same requirements but the area’s commodities which are valued, water, food, land in general, is needed elsewhere. These losses are few in number compared with those of direct losses yet they are of the greatest importance. They are important because they involve the removal of resources of an area in which other inhabitants are dependent upon. A great example of this regrettable indirect expansion is the loss of the rich habitat of the area known as Owens Valley.
Species reintroduction has become a hotly debated topic, especially in the states experiencing actual reintroduction efforts. The reintroduction of the lynx into Colorado appeals to many who would like to return the area to it's pristine, pre-developed state. However, the actual costs, both financial and emotional, make this program impractical and illogical.
Discerning the spatial patterns of biodiversity and understanding their ultimate (why) and proximate (how) causes is very dear to biogeography and is one of the key concepts of Macro ecology. Some places on earth contain more species as compared to others. All species occurring at a given space and time either originated (speciated) there or dispersed and arrived from another place and settled there. Biogeographers try to understand the past and current distributions of species by incorporating historical, evolutionary and ecological factors. Earlier biogeographers or the ‘naturalists’ in their sacred quest to serve ‘the creator’, travelled to various parts of the world and imparted valuable knowledge about the diverse patterns and processes of nature. Linnaeus (1743), on the one hand, hypothesized that early Earth was filled with water except for it’s highest mountain top i.e., Mount Ararat which was known to be the site of paradise and as the sea level dropped the exposed land was colonized by plants and animals that migrated down from high elevational zones of Mount Ararat whereas Willdenow (1805) hypothesized that within each geographical region of the earth, plants and animals were first placed and later survived the great flood on many mountain ranges (Lomolino,2001). Von Humboldt and Darwin in the South American Andes and Wallace Southeast Asian islands noticed the decreasing trend in elevational species richness patterns (McCain and Grytnes, 2010). Later work done by Grinnell (1917), Whittaker (1952), Terborgh (1977, 1985) on elevational species richness became accepted and set a established pattern for all species for more than two decades (McCain and Grytnes, 2010). However current researches on elevational gradients are...
First of all I would have to say that yes it has a great impact on our global warming and I will go on to explain to you how it affects our planet. We as a whole have let the dollar get in the way of how our planet is affected, some would say at all costs. It is true we have refineries, car pollution, but most of all deforestation of tropical areas. In the National Geographic Magazine you will come to see and appreciate the facts of how deforestation has affected our nation and has spiraled into global warming. We can look at Brazil’s rainforest that is estimated to be larger than two hundred football fields it will be destroyed before you are even able to read the article at hand (Magazine, 1996-2014). It has been noted that within the past 40 years we have managed to do more damage than what was done in the four hundred and fifty (450) years since the European Colonization even began. That sent chills through my bones when I read that, imagine how much tropical areas have been affected. We have destroyed twen...
De-extinction is a process that has been experimented with for many years, but has never been completely successful. The ethics and consequences of this idea have been questioned but, de-extinction has the potential to be truly helpful to humans and the environment, and many of the scenarios that people think could happen, are actually impossible. To actually revive a species, there are certain conditions that must be met, and the terrible situations that people think could happen, are unable to actually occur because of the lack of . Bringing species back that are beneficial to the environment could preserve biodiversity, restore diminished ecosystems, advance the science of preventing extinctions, and undo the harm that people have caused in the past. The true potential of the revival of species cannot be realized because people overdramatize the effects and possible outcomes. Once we realize and understand how beneficial the process of de-extinction can be we can better improve our world, our lives, and our ecosystems.
Ecosystems are the basic biological units of ecology, and consist of biotic organisms and their interactions amongst other living organisms, as well as the surrounding abiotic environment (Putman and Wratten 1984). One facet of ecosystems that is less-often mentioned is the process of decomposition, as it many may view it as an unclean, unpleasant process that occurs after an organism has ceased to exist. To those with an ecological framework, however, decomposition is viewed as the opposite – an interesting, intricate process teeming with biological activity and life (Swan and Kominoski 2012). What is decomposition? Formally, decomposition is defined as the process to which complex organic matter is broken down to its basic constituents (i.e.
Sustainable development adapted after the Brundtlandt Report 1987, is a planned, aim- and process oriented procedure that meets the needs of today’s generations without endangering the needs of future generations and world regions (Ott & Döring 2004, 2006).2 The principle of sustainability describes the efforts of the international community, all countries and people to create equal opportunities for development by explicitly taking into account the interests of future generations. Most frequently the concepts of sustainability are based on a triple bottom line represented by the tree pillars – ecology, economy and social security (e.g. by the Enquete Commission, 1998). Apart from the general weaknesses of the column model that is the interchangeability of dimensions and the ignorance of (social) relatedness (c.f. Ott & Döring, 2004)3 the definition of sustainability (the model is illustrating), is seen as a bad compromise between the needs for conservation of natural resources and the aspirations for economic growth by some scholars (Döring & Muraca, 2010). Irrespective of that, the model sometimes is competed by other pillars such as “knowledge”, “institution”, ”governance”, “arts” or the like (c.f. a.o. Ott & Döring, 2004). Whereas in “Resetting the Compas...
Deforestation is defined as the clearing of trees, and the absence of a forest. What most people seem to turn a blind eye to the fact that we need these trees and plants not just for our paper, pencils, or even furniture, but something much greater than any of these things put together. Indeed having a low costly grocery store within walking distance is pleasant, but there are negative consequences as well as positive consequences that coincide with the placement of a Wal-Mart in the city of Oviedo. It is understood to many that industrialization as well as being able to finally have a store that does not charge six dollars for orange juice is a blessing. Fretfully, the negative consequences will
Sustainability simply defined to me as balancing act between the development of sustainability is necessary for both planet Earth and humans to survive. This is reinforced in the World Commission on Environment and Development report (1987) that sustainable development must meet the needs of the present without compromising the well-being of future generations”. The Earth Charter Organization widened the idea of sustainability to respect for a culture of peace, universal human rights, nature, and economic justice (What is sustainability?, n.d.).
The sustainability of the ecosystems on which the global economy depends must be guaranteed. And the economic partners must be satisfied that the basis of exchange is equitable” (World). This quote demonstrates the complexities of sustainability. Another thing corporations should focus on when trying to be sustainable is their environmental impact.
Over the past few decades there have been discourses both in favor and against Globalization’s capacity to guarantee a sustainable future. Authors attest societies and businesses’ inability to account for ecological and environmental limits when dealing with economic growth, examples of this are some of the traditional business metrics used by most global companies, and nations’ measure of wealth (GDP); both sides heavily resting on economic factors, fail to account for societal and environmental concerns (Byrnea & Gloverb, 2002). Other researchers point at the intensive use of resources, especially by global corporations; such as the increasing and careless consumption of fossil fuels, water, precious metals, etc. leading to a rise in GHG (Starke, 2002) (United Nations Development Program (UNDP), 2000). Most fervent opponents go as far as to call ‘sustainable development’ an oxymoron (Ayres, 1995).
Deforestation means to cut down a big amount of trees, which results in damage to the quality of the land. Forests cover 30% of the earth's land, but are lost every year. The rainforest could disappear in about a hundred years because of the existing rate of deforestation.
NEED AND PURPOSE FOR CONSERVATION OF BIODIVERSITY Biodiversity conservation is about saving life on Earth in all its forms and keeping natural ecosystems functioning and healthy. Biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems, climatic changes, pollution, invasive exotic species, diseases, shifting cultivation, poaching of wildlife etc. Since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its forms and should prevent the degradation as well as the destruction of the habitats, thereby maintaining the biodiversity at its optimum level which will ultimately conserve the biodiversity for the future generation. The United Nations designated 2011-2020 as the United Nations Decade on Biodiversity. In biodiversity, each species, no matter how big or small, has an important role to play in ecosystems.
Today biodiversity is being depleted by the loss of habitat, fragmentation of habitat, over exploitation of resources, human sponsored ecosystems , climatic changes, shifting cultivation, poaching of wild life etc. Biodiversity includes various other important things and services such as cultural, recreational, and spiritual nourishment that play a major role in maintaining our personal life as well as social life and since the human beings are enjoying all the benefits from biodiversity, they should take proper care for the preservation of biodiversity in all its form and good health for the future generation. We should conserve biodiversity because of its benefit for example services and biological resources which are essential to live our life on earth and maintain it at its threshold level and derive sustainable benefits for the present and future generation. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach for preservation of biodiversity. Ever since the Conservation of Biodiversity has gained tremendous importance worldwide, steps have been taken for its
