Who are some important contributors in the field?
Anton Van Leeuwenhoek first created idea of food chain (1)
Charles Darwin emerged the concept of evolution through natural selection, and studied phylogenetics (the evolutionary connections between organisms in their genetics and physically) (1)
Ernst Haeckel was the first to use the term ‘ecology’ (1,5,6)
Charles Elton wrote first book on animal ecology where he wrote about the pyramid of numbers (there needs to be more prey than predators), the food chain, and niches of animals. (6,8)
Alexander Von Humboldt is deemed the father of ecology ; He was the first to study organisms relation to their environment, and describe associations of plants and climate (1,5)
Georgy Gause created the Competitive

Loss of biodiversity (variety of species in ecosystems), is becoming an increasingly large issue (2)
Humans overfishing / hunting, polluting habitats, land development, deforestation, climate change, etc, is causing many animals to go extinct or severely endangered (7,8)
When one animal goes extinct, it can cause a ripple effect, and disrupt the balance among the food chain (7,8)
Ecologists facing the problem of biodiversity study how species, habitats, and ecosystems are impinged (a typically negative impact) by human activity (3)
Ecologists work to figure out how to conserve the environment and create solutions for the issues humans have caused (3)
The Convention of Biological Diversity was developed in attempts to take action on the issue of the loss of biodiversity (7)
How has your field changed over time?
Before Sir Arthur Tansley, most ecologists studied organisms separately from and did not connect them to their environment, but Tansley changed that notion around
Summary Aldo Leopold is considered the most influential conservationist in the 20th century. His greatest idea was the “land ethic.” A quote from the movie says: “All ethics so far evolved rest upon a single premise that the individual is a member of a community of individual parts—land ethic includes soils, waters, plants and animals.” Although, Leopold died in 1948, his ideas are still current.
When we study about relationships between living organisms, (i.e humans) and our physical environment, it is imperative for one to comprehend the vital connectivity within our micro, macro, and mezzo systems. Ecology also provides a great deal of information about the benefits of our ecosystems. This can be viewed in the tale of The Other Wes Moore; One Name, Two Fates. When we look at the life of Wes Moore Watende Omari Moore, there is a validity to the many systems and subsystems aided in his advancement in life choices and ultimate outcomes. Some of the examples of such systems which played an intricate role in his life journey are 1)
Both the ecologist and the
The environment does a great job supplying ecosystem goods and services. An ecosystem good is the natural habitat the Modoc bioregion gives to the animals. An ecosystem service can be the animals around the bioregion. They do a numerous amount of jobs around the environment. In fact, they are
Current consensus on global climate change is not promising. As such, efforts have been mounted to reverse this direction, but it is not clear that the implemented preservation and conservation efforts have been successful. Preservation is used in the sense of keeping something in its original state and free from decay, and conservation is used in the context of the protection of nature and natural resources, so the terms will be used interchangeably. Failures of these efforts can be traced back to the 1864 Yosemite Grant and the 1964 Wilderness Act and the problematic precedents they set. The existing paradigm of preservation in environmental science is rooted in notions of settler colonialism and imperialism, and demarcates certain conceptualizations
On September 14,1851 and was recognized and respected as a American writer. James Fenimore became the first environmentalist with his work. His writing is based on the three environmental rules. First that American natural resources are not inexhaustible: That without conservation,we will run out of the trees,minerals,and fossil fuels that have made possible our industries and our high standard of living. Second that our natural environment,including the
Wilson stresses that while there is “no way to avoid the fundamental differences in our worldviews”, it should not keep them separated in every issue and once again provides examples of aspects of life every human strives towards. It is at the end of this paragraph that Wilson addresses the central topic that “the defense of living nature is a universal value” and reiterates that he needs the Pastor’s help. The next paragraph gives evidence to support his claim that nature is in trouble. He asserts this through multiple statistics and scientific estimations. Wilson goes on to argue that every species
Poaching and illegal hunting can cause an off set in the ecosystem by overhunting animals. When one animal population decline drastically, other organisms are affected too. The decline in native predators is the main cause for overpopulation of animals like deer. Deer overpopulation has led to rapid decrease vegetation life causing other animals to be put at risk. Removing predators from the food web disrupts the entire balance of an
In order for here to deliver her message to the best of her ability, her dominant organizational pattern problem- solution because she gives the problem, which is that nature's definition is too strict. The secondary organizational pattern advantages- disadvantages because she states the old claim presented by Bill McKibben, which was that nature is no longer because it has been altered by humans. She also uses many rhetorical devices. The speaker uses irony, express something which is contrary to the intended meaning, when she describes how it takes a lot of maintenance to make national parks look untouched. Use of rhetorical question when asking the audience what counts as nature, so the audience can really think about her concept.
"The Ecological system theory has since become an important theory that became a foundation of other theorists work." Explorable
To sum up, both articles provide evidence that zoos are improving over the years to serve their purpose more effectively. Constant development helps them to save more animals and at the same time show the results to the public which is crucial for inspiring people's participation in conservation programs. So, the two articles on the necessity of zoos are mostly similar as they express the same ideas. Both Cohn and Borrell provide arguments for the significance of zoos which contribute to animal conservation by conducting research, protecting endangered species, encouraging people to participate in conservation programs and forming their connection with the natural
The extinction rate is one hundred to a thousand times greater than it was before the human species evolved on the planet. Currently, Earth is in its sixth mass extinction, with one sixth of all species going extinct. If all of these species go extinct, humans will also be greatly harmed (Worrall). Humans can not continue without the great interconnected biodiversity we currently have, because all animals on the planet are inter-connected in their habits and way of life. If we begin to destroy minor food chains from small-scale animals going extinct, greater and greater
Imagine you live in a world where there are no plants, forest, animals, or oceans all there is in where these things us to be is concrete, landfills of garbage, and buildings. This is what will transpire if we do not protect or wildlife, wildlife conservation is a very important situation as it helps keeps plants and animals off the endangered list. According to the World Wild Life organization there are twenty-six endangered animals and twenty-one critically endangered animals this is very overwhelming as animals are an important part of our environment and ecosystem. With human population increasing at an alarming rate, with the growing rate of humans there is going to be less land for animals and plants, more man-made pollution and plastic debris will go into the oceans, lakes, and streams.
In the earth we share and spend our life with the humans, animals, and plants even the inanimate , and from our unity consist the life and vibrancy. Every element is important to maintain a normal life, every one of them dependent on the other to be together to make a model of continuous life. one of the leading human responsibilities save the natural resources of the land like creatures that dramatically affect each series and even one component can affect the life cycle.
Introduction: Our earth is the most precious gift of the universe. It is the sustenance of ‘nature’ that is the key to the development of the future of mankind. It is the duty and responsibility of each one of us to protect nature. It is here that the understanding of the ‘environment’ comes into the picture. The degradation of our environment is linked with the development process and the ignorance of people about retaining the ecological balance.
