Causes Of Biodiversity Crisis Essay

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.

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

Forests have been cut, crops planted, pastures seeded, and urban areas paved. One of the most troubling consequences of human modification of ecosystems is an ongoing loss of species and therefore a loss of biodiversity around the world. The current extinctions have a human cause: habitat loss (such as clearing of tropical rainforests); the introduction of invasive species; unregulated hunting and fishing; and pollution of water, air, and

Initially, habitat loss possibly poses the greatest threat to species as their homes (biomes) are harvested for industrial purposes and human

In the race to preserve, conserve and maintain biodiversity and its functions in anticipation of the unprecedented and

Since the Industrial Revolution we have practiced deforestation, burned fossil fuels, and as a result we have disrupted stable ecosystems. Advances in medicine and technology have given humans the ability to increase their carrying capacity. While increasing our carrying capacity we have also decreased biodiversity around the world. We have introduced different species in new environments to help ourselves

In this essay I will be talking about how it affects keystone species which is (a species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically)also how biodiversity plays a role in changing the ecosystem.also how there could be symbiotic relationships and trophic cascades also predator prey relationships that could also affect plants and animals in a ecosystem.

Biodiversity is the variety of life on earth. This goes for the genetic diversity, which is what makes a poodle different from a pit bull, ecological diversity, and species diversity. Biodiversity is very important to everybody on earth as our health and survival depend on it. This is why the loss of biodiversity is an issue. Having a great array of biodiversity allows humans to have a greater array of food to choose from and materials to contribute to the economy. For example, imagine if all the chicken went extinct in the world. That would be one less food source for us humans and the predators that eat it.

Conservation biology, ethnobotany, Integrated Pest Management (IPM), Ecologically Based Invasive Plant Management (EBIPM) and Permaculture. All of these are newer ideas in the still young field of ecology. Ecology definition, as given by Wilson in “Diversity” “is the study of the interactions of organisms with their environment, including the physical environment and the other organisms living in it.” (396) In this general field new ideas gain popularity and support they spawn off into

In “Lynn Whites” article “The Historical Roots of Our Ecological Crisis” (1967), he begins by linking the emergence of human exploitative attitudes

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

Humans have existed since 200,000 years but the Earth has existed around 4.5 billion years. Nature has provided us with everything we have today - food, medicines, materials, chemicals, metals, minerals etc. It can only keep providing us when we maintain the right environment for it to exist. This environment depends on the biodiversity of Earth. The number of species of plants, animals and microorganisms and the various genes in these species, different ecosystems such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Hence Biodiversity impacts everything. We will discuss how Biodiversity plays a crucial role on social, environmental, and economic factors. We will also discuss what

A biological community is a discrete, useful and life maintaining environment . The natural system comprises of biotic and abiotic components in a living community if ecosystems are degraded it can lead to increased flooding due to the erosion of soil and lack of trees, rising of the sea levels due to the melting of the glaciers, caused by Global Warming.water shortage, food shortage (as the lands become barren and the oceans become fish less), loss of biodiversity as whole species of living things disappear due to deforestation, pollution will eventually become unmanageable and affect our health, rising temperatures may be too much for all living things on the planet. Yes there are abundant evidence that 25% of our coral reefs have disappeared and it is expected that 60% more will be gone in 30 years. This is due to ocean acidification, water pollution and deforestation has led loss of forest.

One of the primary causes for the loss of a species habitat are humans. Like I said before we humans need and want things and will exercise that action at any cost. More good and space is required as the world’s population grows. The only way to get those things is by taking it. Agriculture land is in high demand with the amount of people that need to be fed and housed. We are able to achieve these lands by

As mentioned prior, the most significant cause of loss of biodiversity is due to animal agriculture. To be more specific, it is due to, again, habitat destruction by deforestation for livestock, overgrazing (and compaction and erosion), which makes the land unable to be utilized afterward, and overfishing. To continue with the topic of deforestation and overall land use, it has been found that forty-five percent of the Earth’s total land is taken up by livestock. With all this land use comes detriments to soil fertility, which means one third of land in general ends up desertified due to the raising of livestock. The demand for more land for livestock use has also had direct disadvantages for wildlife in that, like with the orangutans in the rainforests, they are seen as in the way; they are deemed obstacles and ultimately blamed for their own deaths. This has a fairly obvious connection to the loss of biodiversity. To clarify, for example, according to Deniz Bolbol of the American Wild Horses Preservation Campaign, the government has been rounding up wild horses and burros, so that there are more wild horses (fifty thousand) in government holding facilities in the United States than there are free on the range. This is because ranchers are getting land which the government then divides up giving what they deem the appropriate amount of land for forage, water, “wildlife,” and the wild horses and burros. What has been found is that the government is giving a large share to
