Abstract
Of all the forests in the world the rain forests are the most diverse and are being destroyed at the greatest rate. Rainforests cover only about 5% of earth, but they contain 50% of her species. This paper discusses the importance of Forests and shows that Forests are the most valuable eco-systems in the world, containing over 60 per cent of the world's biodiversity. This paper emphasizes the importance of maintaining this important natural resource and what it means to our environment.

Abstract
In this article, the writer discusses that it is a generally accepted fact that biodiversity must be preserved not only for the aesthetic inheritance of future generations, but also for the continuation of life on earth. Indeed, the topic has been the focus of many a lecture, seminar and conference on sustainability and economics. The concept of overprotection for biodiversity might therefore seem somewhat bizarre to the uninitiated. The writer maintains that the term overprotection should however be understood in a particular sense in order to make sense in the context of biodiversity, conservation and sustainability. Only when this understanding is achieved, an assessment can be made regarding the possible overprotection of biodiversity. In conclusion, the writer does not think that biodiversity is overprotected, but believes that the protection that is available for biodiversity throughout the world is handled incorrectly.
From the Paper
"Human beings today, especially those living in urban areas, tend to be separated from the natural environment that sustains them. Everything is made available in processed form. The urban citizen is no longer responsible for hunting, farming or slaughtering his or her own food. Hence, when problems such as sustainability and biodiversity present themselves, it tends to be romanticized in the minds of those not directly affected. It is as if the urban citizen is obsessed by these ideas when they are broadcast over the media. It is the fashion, as it were, to be concerned with the environment. Such concern however does not directly affect those responsible for laws governing environmental conservation and sustainability."

Abstract
Biodiversity or biological diversity is the study of living organisms in relation to the environment. This paper explains that, because Ontario has significant natural resources, there is a growing concern to protect the ecosystems that support all life in the region. Plants animals birds and insects are dependant on the land and waterways within Ontario, and it is up to the current social order to ensure that these elements of the environment are protected.

Abstract
The paper discusses how ecologists are concerned about the conservation of biodiversity, for the future inheritance of the earth and its beauty and for poverty and hunger alleviation. The paper looks at several studies that show that conservation parks in tropical countries make a substantial difference in preserving biological diversity. The paper maintains that it is vitally important to preserve as much biodiversity as possible, and to do so particularly in countries where biodiversity is richest. The paper concludes that conservation managers need to put practices in place to target potential investors for the future preservation of the earth and its resources.
From the Paper
"Biodiversity and conservation have been difficult issues in the ecological field. This is not least so because of issues such as increasingly rapid species extinction and also the increasing human population and influence upon the natural environment. Nonetheless, ecologists are concerned about the conservation of biodiversity, as such conservation holds advantages not only for the future inheritance of the earth and its beauty, but also on a more practical and economic level. This is so because the diversity of species on earth have consequences for the often fragile ecosystems we as human beings share."

Abstract
This paper describes various types of ecosystems. The paper defines an ecosystem as all of the organisms and their physical environment that exist within a certain, specific area, including all plants, animals, water, dirt, rocks, and the surrounding air. The paper includes a discussion of a complex mature forest ecosystem.
From the Paper
"The word ?ecosystem? is used frequently in the popular media, and yet most people do not have a clear, working definition of an ecosystem. An ecosystem simply refers to all of the organisms and their physical environment that exist within a certain, specific area. This includes all plants, animals, and their environment, which can include water, dirt, rocks, and the air that surrounds them. For example, all of the organisms that live in a New England tide pool, plus their physical environment would make up an ecosystem. In addition, a deciduous forest and a salt pond marsh are also ecosystems."

Click here to show/hide summary
Abstract
This paper assesses the ethical and utilitarian arguments concerning animal rights in respect to global biodiversity. In respect to the question of biodiversity, it is questionable as to whether there is an ethical position as to why animals should be preserved, or whether humanity justifies their support of animal rights due to purely self- serving reasons. This paper investigates whether animal rights in this instance is created out of concern for the animals themselves, or whether the argument is merely justification for preserving the welfare of the human race.

"Native Knowledge for Native Ecosystems", 2007.
A review of Robin Wall Kimmerer's article, "Native Knowledge for Native Ecosystems".

Abstract
This paper briefly reviews Robin Wall Kimmerer's 2000 article, "Native Knowledge for Native Ecosystems" and highlights the article's main points as well as how it approaches the broad concept of ethno-ecology. More importantly, the paper also touches upon how the article approaches the linkage of local and/or traditional knowledge of ecological systems with academic and/or scientific knowledge of those same systems. Finally, the paper discusses the significance of the aforementioned linkage as it pertains to the future of human beings in the global ecosystem.
From the Paper
"Simply put, Kimmerer's argument is that Native Americans intensively cultivated the land so that it would provide them with sufficient foodstuffs to brave the grueling winter months. While modern-day efforts to restore the ancient biological vitality and bio-diversity of the American woods and ecosystems is a laudable goal, it is not possible without also considering how the natives were able to so successfully manage the world around them. In effect, Kimmerer argues that modern-day conservationists must "heal" their relationship to the land and understand the land spiritually and emotionally as well as intellectually. Less abstractly, Kimmerer states that twenty-first century man must adopt the "site-specific" or "diachronic" knowledge which well-served Native Americans in the past and which lends itself to successful local site restoration.

Biodiversity, 2004.
An analysis of evolutionary history and biodiversity.

Abstract
This paper examines the issue of biodiversity through a review of an article, "Hotspots and the Conservation of Evolutionary History" written by Wes Sechrest and Thomas M. Brooks and published in "The National Academy of Sciences". The paper contends that the article stops short of attempting to identify any possible solutions to this impending problem. The paper claims the it does help to illuminate some of the shortcomings of current conservation strategies; namely, a conservation strategy focused upon preservation of single species ignores much larger trends of extinction that mankind imposes upon the natural world. The paper explains that the ideologies that the study relies upon are implicit and the article itself merely warns that the consequences of ruining seemingly insignificant expanses of land possess the potential to be quite severe.
From the Paper
"An article written by Wes Sechrest and Thomas M. Brooks and published in The National Academy of Sciences reveals the results of a study they conducted investigating the varying levels of biodiversity distributed throughout the world. The authors employ a fairly novel approach in their measurements of biodiversity, specifically, relying upon two methods approximating the levels of evolutionary history endemic to twenty-five terrestrial "hotspots." The significance of evolutionary history as a measuring stick is that it is associated with the past importance of particular geographic locations, and implies that future evolution is threatened if these locations are threatened."

Abstract
This paper explains that, for millennia, Lake Baikal?s ecosystem has flourished in total isolation, untouched by the human population. Unfortunately, today, this precious Siberian ecozone is feeling the negative effects of human abuse. The author points out that the Baikalsk Pulp and Paper Mill (BPPM), one of the region?s oldest functioning industries (around 40 years), is the major polluting source because it exploits an old and highly dangerous method of bleaching pulp by using chlorine. The paper relates that, over the last decade, world environmentalists have helped improve the situation and limited the damage to the delicate ecosystem, but a coordinated effort from the Russian and Mongolian governments is indispensable for tackling this environmental crisis.

Conclusion
From the Paper
"The biological importance of Lake Baikal is evident from the UNESCO declaration of Lake Baikal as a world heritage site and ?the most outstanding example of a freshwater ecosystem?. The range of climatic conditions within the surrounding areas of the lake has contributed to a rich variety of plant life in the region. While the Coniferous forests occupy the western regions, pine forests are common in the eastern areas and deciduous forests predominate the northern region. The fauna found in the lake is amongst the most diverse in the world with more than 255 amphipod species and 80 types of flatworms. The epishura, a tiny crustacean is the natural cleaning mechanism for the lake as it consumes all the decaying matter in the water. The most important and the only mammal species in the lake is the endemic Baikal seal (Phoca sibirica)."

Abstract
This paper explains that numerous factors account for variations of global patterns of carbon accumulation. The author points out that some of these factors are climate, precipitation, cultivation, degree of irrigation,and altitude. The paper relates that also very significant, especially for tropical and temperate forests, are the measurement standards applied.
From the Paper
"Numerous factors account for variations of global patterns of carbon accumulation. Among those factors are climate, soil texture, soil cultivation, amount of nitrogen in soils, and the interaction of altitude and precipitation. Also very significant especially for tropical and temperate forests are the standards applied; not only do these studies use differing measurements depending on the ecosystem, but variations in measurements must often be used within a single ecosystem because of forest floor diversity (Schlesinger, 1977). One factor is geomorphological and/or hydrological instability in swamp and marsh, especially when edged by tree growth."

Abstract
This paper explains that the impression that all of Mexico is hot and dry and made up of mostly rural societies is wrong. The writer points out that the countery also contains icy mountain peaks as found in the Sierra Madre systems, lush jungles and agricultural regions as found in the temperate tierra templada and exquisite coastal zones along the Pacific Ocean and Baja California. The author explains that anthropologists have traditionally divided the ethnic categories of Mexico into two categories, the Indian and the Mestizo; today the majority of Mexican society is mestizo, one of the most distinctive sociological elements of Mexico. The paper relates that because of the variety of these topographical and geological regions, vast species of flora and fauna thrive despite the interference of the modern-day world.
From the Paper
"All of the major topographical regions of northern Mexico run north and south and can be viewed as extensions of regions within the southwestern United States. The Sierra Madre Occidental is thus an extension of the Sierra Nevada; the Sierra Madre Oriental which defines the eastern edge of the highlands of northern Mexico is an extension of the Rocky Mountains. The Sierra Madre Oriental runs from the border with Texas south to the northern part of the state of Puebla and although narrower than the Sierra Madre Occidental, it reaches higher altitudes, peaking at over 3,700 meters in the state of Nuevo Leon. In this environment, "animal life is rich and is reminiscent of those biomes elsewhere in the world with similar vegetation characteristics." "

Abstract
This paper examines the world's ecological systems. It begins by defining ecosystems and describing what makes them up. It then describes the formation of different ecosystems. The paper then looks at what is being done to protect and promote the ecological systems in the world and if these measures are effective.
From the Paper
"The Endangered Species Act of 1973, often referred to as 'nature's safety net,' was passed to protect and recover imperiled species and the ecosystems upon which they depend (Endangered). In other words, when management practices and other conservation laws fail to maintain healthy animal and plant populations, the ESA acts as a last barrier to a species' extinction (Endangered). When a species becomes listed on the ESA list, it stands a good chance of survival, yet then the more difficult, time consuming, and expensive task of reversing the decline, restoring the species to a secure status, and removing it from the list begins (Endangered)."

Abstract
The following paper examines how fossil fuels affect climate and contribute to global warming as well as the way in which acid rain and oil spills affect local wildlife. The writer also discusses the effects of mining waste, farming and pharmaceutical waste.
From the Paper
"Fossil fuels have become a major factor in our lives, they are used to power cars, ships, aircraft's and entire economies but at an ecological price. From the combustion of fossil fuels is water and carbon dioxides. This the major waste gases. Others include nitrous oxides, carbon monoxides and sulphur oxides. These contribute vastly to global warming. When the sun radiates electromagnetic radiation through our atmosphere it hits the earth and then the earth reflect this back in the form of longer wavelengths as infra red radiation. "
