Recommended: Effects of global warming on the ecosystem
Conquerors and competitors, that’s what humans and all animals are to a point; every living thing on Earth has one mission: survive and reproduce. The balance of the environment relies on this concept of constant competition, but this balance also has checks and controls if it is damaged or becomes unstable. Humans have developed to the point where they can completely exploit the environment however they want. There are no natural predators to control our population, we fight diseases with ground-breaking technology, and we replace native plants and animals with ones that fit our “needs” more suitably. We have, in a sense, created our own world of culture and trading that is separate from the natural world. In this new world, economic prosperity trumps all, and conservation and preservation takes a backseat if the dollar signs aren’t favorable. This realization has led many, including one of the founders of conservation, Aldo Leopold, to be pessimistic about whether a system of conservation based on economic self-interest can succeed. He states in his work The Land Ethic, “a system of conservation based solely on economic self-interest is hopelessly lopsided” (756). I, on the other hand, have more faith and optimism that humans will realize the importance of this other world, and live in harmony with it. I believe this because of the possible consequences of exploiting the natural world, the eventual realization that we need to conserve resources for future use and our future physical and economic survival, and the recent trend that these scenarios are starting to be realized, put into practice, and educated to others. Humans have the natural instinct to survive, and a higher level of thinking and problem solving will accompany th...

Define the following terms/ Ideas based on your review of Leopold's discussion of "the land ethic,"
As discussed previously, Kareiva and Marvier argue that focusing on human welfare does not have to sacrifice biodiversity (962-969). However, some find that the argument only holds when conservation itself is tied to a clearly outlined conservation agenda (Sanderson and Redford 389). For conservation efforts to be successful, multiple countries and agencies need to cooperate (“Lecture Week 13”). Conservationists, economists, and political strategists must find conservation issues that do not hinder efforts to alleviate issues of the human condition such as global poverty and world hunger. In actuality, biodiversity loss and poverty are linked, but conservation strategies that will reap success in integrating the two need clear conceptual frameworks (Adams et al. 1146). In order to find a balance and to foster stability for lasting and sustainable development and environmental health, it is important to take humans out of the equation when assessing the status of the environment, and to implement formal scientific strategies to conservation policies (Erwin
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!
Leopold defends his position the advent of a new ethical development, one that deals with humans’ relations to the land and its necessity. This relationship is defined as the land ethic, this concept holds to a central component referred to as the ecological consciousness. The ecological consciousness is not a vague ideal, but one that is not recognized in modern society. It reflects a certainty of individual responsibility for the health and preservation of the land upon which we live, and all of its components. If the health of the land is upheld, its capacity of self-renewal and regeneration is maintained as well. To date, conservation has been our sole effort to understand and preserve this capacity. Leopold holds that if the mainstream embraces his ideals of a land ethic and an ecological consciousness, the beauty, stability and integrity of our world will be preserved.

It is becoming increasingly certain that climate change will have severe adverse effects on the environment in years to come. Addressing this issue poses a serious challenge for policy makers. How we choose to respond to the threat of global warming is not simply a political issue. It is also an economic issue and an ethical one. Responsible, effective climate change policy requires consideration of a number of complex factors, including weighing the costs of implementing climate change policies against the benefits of more environmentally sustainable practices.

Background and Audience Relevance: There are always conversations about our planet. We see our earths glaciers melting, weather temperature rising, and pollution affecting our resources. But for some reasons we tend to look away. We should be more aware of this potential event and I’m here to inform everyone about what actually is global warming and the effects of it.

Various plant and animal species depend on each other for what each offers and these diverse species ensures natural sustainability for all life forms. A healthy and solid biodiversity can recover itself from a variety of disasters. It is estimated that the current species extinction rate is between 1,000 and 10,000 times higher than it would naturally be. Therefore, there is an urgent need, not only to manage and conserve the biotic wealth, but also restore the degraded ecosystems. c) Captivity breeding species can again be reintroduced into the wild.
