“Ecological resilience was defined as the amount of disturbance that an ecosystem could withstand without changing self-organized processes and structures” (Gunderson, 2000). Ecological resilience describes the threshold of the stable system. The disturbance into the system is resulting positive and negative feedback which influence the weight and period of the resilience (Gunderson, 2000). Human makes the biggest disturbance into the ecosystem resilience. The argument is whether ecosystem could return into the previous state before shift into new state after introduce by human’s disturbance (Standish et al., 2014)
The example for the relation of biotic feedback mechanism that affects the ecosystem resilience and regime shifts could be found
The destruction of various ecosystems through modalities such as bulldozers, cranes, and irrigation systems have shaped the current state of the world. As countries continue to industrialize many parts of the world are becoming increasingly urban. The desire to turn undeveloped areas into bustling cities has been exorbitantly transformative in the state of the world's ecosystems. Increasing populations resulted in a greater amount of socio-economic, agricultural and industrial activities (Schultz). Therefore, a high stress was placed on local ecosystems to meet those demands. Cities now lack
Environmental pollution can adversely influence the ecosystem by minimizing the health and safety of the neighboring environment much needed for the organisms’ to existence. Habitat destruction is the second hazard that comes from human life increasing. To maintain human’s keep living, it is required to create regions for urban development, agriculture, and other much needed elements and pleasing living factors. Then again, the necessities to please the life of humans pose a threat to the life of organisms in the particular area. In the temperate forest ecosystem, numerous abiotic features play a part of its continued existence between the local organisms. The abiotic factors, which are nonliving factors that affect living organisms, are example things like its weather, light source, temperature, soil, minerals, air and water. The combination of these elements aid in the survival of the ecosystem alone and provide certain survival of the organisms in the environment (Viau, 2000). The organisms in the temperate forest ecosystem have undergone adjustments to assist or sustain the available resources and live through in the surrounding environment. Suitable modification ensures the survival of an organism in a particular
In Brian Parham’s article “There Are Multiple Threats to the Earth’s Environment,” published by The Bridge website on November 18, 2012, Parham claims that Earth’s environment is threatened by a wide variety of issues. Parham 's "There Are Multiple Threats to the Earth 's Environment" is an effective argument due to the strong uses of ethos and pathos, despite the weak use of logos.
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
It is commonly acknowledged that, in a biological ecosystem all species are closely affected each other through a food chain. However, what people don’t really recognize is how hugely one species can affect the entire ecosystem. The reintroduction of wolves in Yellowstone National Park depicts a vivid example how one predator can contribute to the recovery of biodiversity and its astonishing impact on physical geography.
More than 20 football fields of trees are removed each minute. Logging can affect plants and animals by losing their homes. Predator - prey relationships will alter which can then cause a trophic cascade by overpopulation from the prey or extinction of predators. Also keystone species could be removed by these factors. So these living and nonliving factors could affect an ecosystem in many ways. Changes affect the ecosystem strongly in ways which population could boost in biodiversity or severely diminish the population of both plants and animals.
If we go all the way back to the time when man first began to explore all corners of the earth, they have had to carry food and other provisions with them to sustain themselves along the way. In addition, explorers seeking new land also carried with them familiar animal and plant species to establish colonies in new places. Unbeknownst to them at the time, they were the ones directly responsible for breaching the delicate barriers that isolated biogeographical biotas from one another. On the other hand, this was not the only these non-native species were and are able to wreak havoc on the various ecosystems and communities. What’s more, these intruders have learned to alter themselves and adapt in response to their interactions with native
Lorenz (2013) defined ‘resilience’ as the ability to keep continuity by avoiding or withstanding failure. Over the course of history, the pieces of archaeological and geological evidence illustrate the short and long-term impacts of natural disasters on the human population. In most cases, people believe that disasters only bring negative effects to the society. However, the destruction caused by disasters is not permanent, and people can rebuild their civilization later. Moreover, abrupt changes in climate force people to adapt to the new environment, and social resilience increases at the same time. During the early Holocene period humans combated natural disasters by seeking refuge, inventing new technologies and by creating reciprocating social networks.
In conclusion, many things are impacting the populations and changes in the ecosystem. Lions impact their ecosystem and control the populations through predation. Keystone species like bees are highly depended in their ecosystems and have many symbiotic relationships. Finally there are nonliving changes like global warming changing the environments all over the world. I believe that we have changed the Earth so much and that it has changed so much itself that there is nothing we can really do, but just let them happen.
For example, by “burning and cutting trees, grazing animals for longer and at greater densities” not only cause harm to the ecosystem but also to the natural life. He uses multiple kinds of literature to back up his argument that “rewilding” is not only to reintroduce the missing plants and animals; it also supports earth’s life, an ecosystem that provides basic needs and natural defence against climate change. He gives his own views on his research and states that rewilding is not only aiming to save species animals but also saving out the natural world. Monbiot’s approach was directly linked to the saving species by restoring agricultural plots, being less expensive to purchase land and allowing reconnection of existing natural areas to increase habitual species. He used a variety of evidence to support his concern and the article was well cited for the information that was used from other literature.
We as humans are causing an excessive amount of habitat destruction due to industrialization and creation of infrastructures. We’ve polluted the air with smokes and fumes, torn down forests to build shopping malls and highways, and degraded and overused the soil for our own profit. We are so concerned with furthering our industries and businesses that we forget that the earth is the main source of it all. We also fail to replace what we use. Because we continue to hurt and destroy mother earth, she will eventually become a pile of nothingness.
The short term environmental consideration of building reef resilience include components such as nature; intensity and length of time of effects that will be set in place so that groups of people, animals of species and homes where they reside will recover from effects more expeditious and consequently, sanction the community to perpetuate functioning at a positive rate. Fish are a great benefit to the environment and 1,625 species of fish, virtually 10% of the world's fish species lives in the Great Barrier Reef so, it is highly recommended that we should maintain the reef and look after the other species that live in this world history listed reef. The long term of building reef toughness can include limits in species and this could
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 decline of the environment due to natural and human exertion is known as the degradation of the environment. The natural weather occurrences such as heavy rain, flooding, storms, earthquakes, volcanoes etc. are not administered under human control. These meteorological phenomenon’s wreak devastation on the environment from time to time causing the land to become unsuitable to cultivate. On this subject matter, the human population does not contain the power to stop the wrath of Mother Nature. Rather, we are forced to sit back and watch. Nevertheless, humans engage in a crucial role towards the degradation of the environment in which we live in. Unavoidably, the degradation of the environment is a rising and utmost worldwide subject. I accept that the root cause to environmental degradation is the excessive use of resources on our land utilized by the processes under capitalism. As Jensen wrote in Endgame, “The global industrial economy is the engine for massive environmental degradation and massive human and (nonhuman) impoverishment.
