Ecosystems is the dynamic complex of plant, animal and micro-organism communities and their non-living environment that work together to form a functional unit and they are constantly changing due to the fluctuating equilibrium from natural stress and human action which has had adversarial impacts on ecosystems. This is evident in Minnamurra rainforest as human induced modifications and environmental stresses had resulted in a vulnerable ecosystem. Furthermore, the removal of factors that contribute to the vulnerability of an ecosystem is important as it affect the functioning of the ecosystem as processes are accelerated, biodiversity is decreased which greatly affects humans. Despite the negative effects caused by humans, they have discovered that ecosystems are susceptible from harm caused by natural environmental factors or human impacts and realised the importance of protecting and managing ecosystems therefore have implemented management strategies that are supposed to prevent further detriment and as a consequence may induce resiliency.
David Shabazi Professor Loza-Coll BIOL107 11/17/15 Mini Research Proposal Background: Every ecological system provides multiple services for the organisms that live in that specific ecosystem. Some more than others, depending on the biome and health of the environment. One of its roles serve to act as a resource base, available to all nearby organisms for survival purposes. This "resource base" is finite, however. When not used wisely, resources will most often deplete dangerously quickly, resulting in irreversible reduction of something we call "carrying capacity" of a population(s) (Arrow, 92). Carrying capacity, denoted as “K” is not limited to animals in a forest, or sea creatures in an ocean; it exists for microscopic cells, as well. The factors involved in affecting the carrying capacity of an animal population are very similar to the factors for cells, and the curve on a graph showing values of K behaves identically, for the most part, to cell populations as well.
The message of the Millennium Ecosystem Assessment’s Governing Board is that human impacts on this resilient natural world are so unprecedented and extensive that we crossed the line into unsustainable consumption some time ago and are now depleting ecosystem capital stock instead of living off its sustainable goods and services.
The audience of this book is presumed to be the general person who is not fully intact with the ideas that he or she is disrupting the ecosystem and is not aware of the effects they are doing as a whole. The book argues that no ecosystem is completely inert as things such as climate changes or drought can also affect the enviorment. Without human interaction an environment can still have issues, but the introduction of human life and economy does take a grave toll on the climate. These are irreversible effects that mankind are doing to the ecosystem. The English
In the first two centuries of U.S. history was a widespread environmental destruction. In the 19th century there were four people who played a key role in protecting the environment; Henry Thoreau, John Audubon, George Marsh, and President Theodore Roosevelt. The modern environmental movement was in the 19th century Europe and North America as they exposed the cost of environmental negligence. Rachel Carson a Marie Biologist wrote a book in the 1960’s

The conservation movement of the nineteenth and early twentieth centuries and the environmental movement which came about after 1950 had symbolic and ideological relationships, but were quite different in their social roots and objectives. A clear point is that especially in the beginning, only the elite, wealthy class, had time left to think and enjoy nature and joined the environmental movement organizations. It was born out a movement of amateurs. The organizations of the environmental movement viewed natural resources such as water, land, and air, as recourses that would improve the quality of life (Sandbach, 1980). The conservation movement grew out of the idea of how to use water, forests, minerals and animals, fearing that they

“Hunting and ecosystem-based management is the smartest and most cost-effective way to manage our wildlife. The basic idea of ecosystem-based management is that you manage ecosystems rather than specific species or disciplines.” For example “you do not mange pheasants as much as you manage the ecosystem in which the pheasants live. If the ecosystem is improved, it will produce more pheasants naturally.”(1)
Interdependence of the social, scientific, economic, and political processes involved in protecting habitats is as complex as the interdependence of the ecosystems they are intended to protect, oversimplifying these processes leaves them especially susceptible to failures within the system. The current environmental protections in our political system are dependant upon the ability and interest of a third party voicing concern for the rights of ecosystems and species that are not able to represent themselves. Additionally, policies intended to protect habitats fail to recognise the interconnectedness of other local species and conditions necessary to protect the ecological systems they are meant to protect. In a system where protection is dependant upon the ability of a specialist to identify the presence of definitive signs of species
The Historical Roots of Our Ecological Crisis White’s thesis in The Historical Roots of our Ecological Crisis states that in order to confront the expanding environmental crises, humans must begin to analyze and alter their treatment and attitudes towards nature. The slow destruction of the environment derives from the Western scientific and technological advancements made since the Medieval time period. “What people do about their ecology depends on what they think about themselves in relation to things around them” (RON p.7). Technology and science alone will not be able to save humans until we adjust the way of thinking and suppress the old ideas of humans power above nature. Instead, we need to learn how to think of ourselves as being
The environment generally refers to the surrounding’s of an object or an individual. It can be in the form of the physical environment, biophysical environment, built environment, social environment and the natural environment among other forms. The natural environment refers to the naturally occurring flora and fauna together with the
