Aldo Leopold’s Land Ethic

Aldo Leopold is considered to be one of the greatest philosophers of environmental ethics of all time. Scientist, forester, environmentalist, and professor at the University of Wisconsin, Leopold has influenced and shaped today’s environmental ethics. He impacted many environmentalists with his environmental ethics and emphasized the importance of biodiversity and ecology. Leopold’s most praised work is “Land Ethic” in A Sand County Almanac that he wrote. In this essay he emphasized the importance of conserving our environment and being part of it, instead of destroying it. In Aldo Leopold’s essay he wrote “land ethic changes the role of Homo sapiens from conqueror of the land-community to plain member and citizen of it. It implies respect for his fellow-members, and also…

How can we protect our natural environment?

The environment is our planet. It provides us with natural resources that are used for everything. It needs to be protected and so future generations can leave with no environmental problems as we are facing nowadays. Some countries develop with sustainability, this means that hey use the resources tht the planet provides in an efficient way so future generations can use them. To begin with, we can protect our natural environment by doing simple things that everyone can do. For example we can protect the environment by using the less we can the electricity, or by not throwing the garbage to the floor, instead yo toss it in the trash can , we can also recycle. Using public transports is…

Ecological Concepts

Ecology is the study of the relationship of between organisms and their environment, including both the living and nonliving compounds. Some of the ecological concepts include succession, energy flow between trophic levels, limiting factors, and carrying capacity. First, succession is a change in species structure of an ecological community over time. Over time species in the community become more and more abundant and may not be present at all one day. Also, sometimes new species might invade the community from nearby ecosystem. Ecologic successions occur as a result of drastic change in the environment or species inability to reproduce or grow in a particular environment. There are two types of successions primary and secondary. Primary succession is when an area…

General Principles of Ecology

The term ecology refers to the study of abundance and distribution of living organism in an ecosystem, together with the interaction that exists between them and the natural environment. The distribution of organisms is usually influenced by the adaptation of a certain organism to the environment. An adaptation refers to an organism’s ability to exist successfully in a given environment. Therefore, organisms can only exist in environments that they are adapted to. When a given species of animal or plant is adapted in a given natural environment, then it becomes distributed in that environment densely and in high numbers. Those that lack the ability to adapt well are poorly distributed, since they cannot cope with the pressures or stress that…

Religion and Ecology

Every thread of the problems faced by the present human society can be traced back to first industrial revolution of late 18th century and early 19th century that took place in Britain and from where it was embraced by the entire world. The industrial revolution set in motion the process of changes that have since then subsequently transformed the character of not only human society but of entire earth (Gatta, 7). Air, water, land and sky, all bear the effects of the changes inflicted by human march through industrial revolution and the effects have not been pleasant by any order. The modern society is the product of new-classical theory of economics and the anthropocentric view of environment, both of which…

Ecology Exam

Q1. A patchy environment is an indication of a reduced resource density. According to Smith et al (2008) changes in environment affect species diversity and relative abundance of species. Thus per foraging, the tendency of a species to concentrate its activity in a patch rather than distribute its activities uniformly increases with the availability of resource density. This is affected by the travel time or the quality of the patch as beneficial to the organism. Host and parasite populations will persist roughly at steady densities in a patchy environment due to a variation in parasitism levels from patch to patch. Actually this occurs as a result of inadequate ecological heterogeneity (Hassell, 1978). Q2. Mutualism is an interaction between two different…

Ecology Lab

The ecosystem is composed of the producers, consumers, decomposers and the nonliving or abiotic components (Ecology, 1997). The producers are the plants that produce food through photosynthesis. The consumers have two types: herbivores or primary consumers and carnivores or secondary consumers. The herbivores are the animals that only eat plants while the carnivores are the animals that only eat meat. The animals that eat mixtures of plants and meat are called omnivores. Human beings are considered as omnivores. Fungi and bacteria are some of the decomposers in the ecosystem. The nonliving or abiotic components of the ecosystem are consisting of the dead organic matter and nutrients found in soil and water. What if all humans became vegetarians? Would it be…

Ecology Report of Brighami Rockii

Any region with significant level of biodiversity exposed to threat of destruction can have severe deforestation and other forms of agricultural clearing like logging, charcoal-making, etc. Due to this degradation of its ecological habitats, such region may become a home for critically endangered endemic species. Researchers have it that the less rainforest a given region has, the greater the proportion of endangered species it hosts. In Hawaii, two native plants were identified as the most critically endangered species. Brighamia rockii & Brighamia insignis are endemic to the region. Both of these species are similar to each other except their respective colors. Both of them also have succulent stems that function as water storage allowing them to sustain amidst drought season….

Deep Ecology and Its Relation to the Third World-Guha

This paper will begin with an exposition of the article, “Radical Environmentalism and Wilderness Preservation: A Third World Critique” written by Ramachendra Guha, a sociologist and historian involved in ecological conflict in the East and the West. In this article, he refers to American environmentalism as “deep ecology”, a modern theory founded by Arne Naess. Guha’s argues that based on a comparison of the concepts of deep ecology and other cultural environmentalisms, deep ecology is strictly rooted in American culture and thus, leads to negative social consequences when it is applied to the Third World. This argument will be achieved by first defining deep ecology and its principles. Next I will offer Guha’s critique of deep ecology which consists of…

Ethics of Ecology

Ethics of ecology focuses on sustaining business and environment. Ethics is a set of principles about right and wrong and how human beings should behave. Ecology is about inter- relationships – between living organisms (both plants & animals) and between biological & physical entities. As people now realise that the environment is a limited resource, awareness all over the world of the necessity to protect and save the environment has grown as well. From the Bill of Rights, Chapter 2, of the S.A. Constitution, “Everyone has the right ¬ a.to an environment that is not harmful to their health or well-being; and b.to have the environment protected, for the benefit of present and future generations, through reasonable legislative and other…

Case: Gas or Grouse?

1. Systemic issues: Questar is a company and it knows that every mining activities in Mesa will affect the ecological environment. But BLM did nothing since Questar had damaged the local environment. And we know many gas companies have special relationship with governments. Corporate issues: Questar has destroyed the environment when the mining operation was begun. Individual issues: The people who live in Pinedale Mesa believe the drilling activity bring numerous benefits, including jobs, revenues, and local economy. So they welcome the gas companies go to there. 2. Maintain their natural habitat. Protect the existing population, prevent from extinction, facilitate them to breed. If Questar have high awareness for Concerning with environment impacts, this value can be balanced against the…

World Environment Day

Environment Day is a special day to condition of environment. It is important that every age of person should contribute and plays a very important role for creating the awareness. As I mentioned above that Environment Day is celebrated each year on 5th June. It is considered to be the most special and important day introduced by United Nations. Now the question is that what people do on this special day? I would like to mention that Environment Day is celebrated in different ways in many countries such as Kenya, New Zealand, Poland, United States and many other countries. Major and important activities that are held on this day are street rallies, parades, concerts, conferences, seminars, tree planting etc. In…

Declamation

Ecologists point out that the huge expansion of hydro-power projects and construction of roads to cope with the lakhs of tourists in Uttarakhand and Himachal Pradesh has compounded the scale of the disaster. Sunita Narain, director general of Centre for Science and Environment said, “This is very much a man-made disaster. There are of course links between climate change and extreme weather events as has happened with the torrential rain in Uttarakhand. But this has been exacerbated by the reckless construction of buildings, dams and roads in a fragile environment. Many of the settlements have been built right next to the rivers in blatant violation of environmental laws. There is a strong need to evolve a holistic Himalayan policy which…

Ecological Systems Theory

As I was growing up, I always heard of the expression that “people are a product of their environment”. I never gave this expression much thought until I got older and became more aware of my surroundings and my own environment. Personally, I feel that there is some truth to this statement. A person’s environment is very influential to their development. A famous psychologist that studied child development, Dr. Urie Bronfenbrenner, developed the ecological systems theory to show how a child’s development can be influenced by their environment. Dr. Bronfenbrenner felt that “a person’s development is the product of a constellation of forces-cultural, social, economic, political- and not merely psychological ones” (Fox, 2005, para 6). According to an article by…

Calamansi Leaves Extract as Mouth Wash

Ecology – is the scientific study of interactions among organisms and their environment, organisms have with each other, and with their abiotic environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), number (population) of organisms, as well as competition between them within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. Ecosystem processes, such asprimary production, pedogenesis, nutrient cycling, and various niche constructionactivities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity. Biodiversity, which refers to the varieties of species,genes, and ecosystems,…

Impact of External Environment to Business in China

Introduction Nowadays, China is experiencing a rapid economic growth. By following the end of the eleventh National People’s Congress of People’s Republic of China recently, China is emphasizing to develop seven new strategic industries with the release of the Twelfth Five-Year Program. As China is achieving a low carbon economy, thus one of the new strategic industry, new energy is essential to the success of achieving the goal. Biomass energy is one of the new energy which generates electricity and biodiesel by burning agricultural straw, fruit, wood and animals waste (1). The following will be the analysis of Macro-environments for the China Light and Power Company Limited to enter the China market, and suggestions will be given at the end…

Environmental Effects When Species Become Extinct

Animals are, like us, endangered species on an endangered planet, and we are the ones who are endangering them, it, and ourselves. They are innocent sufferers in a hell of our making. Now a days is common to listen that more and more kind of animals are going to be part of a long list of species in extinction called “the red list”, When a animal is endangered it means that they are disappearing fast or have a very small population. Every day we can see in the media the great campaign that is carried out to preserve these animals, as for example: they are keeping in zoos, they have attended reproduction, they have their habitat protected, and however, it…

Plant and Animals

Topic: why are some kinds of animals on the verge of extinction? Nowaday, the number of animals in the world is reducing that people is main reason. The growth of the population, the increasing needs of human life and the advancement of science and technology has affected animals. For example, people made medicines from horn of rhino, so they killed a lot of rhino result in this species going to extinct. Almost all types in the past, animals lived on earth were extinct and vanished in a “natural” way because of this reason or the other. One of the causes contributing to the extinction of animals is environmental change. Earth has existed for more than tens of millions of years…

Be able to rank from smallest to largest: ecosystem, landscape, biome, biosphere Be able to rank from smallest to largest (in terms of numbers and diversity of life): species, population, biota and biosphere. Also, what is the difference between a population of a species and a species overall? Make sure you can explain the Law of Limiting Factors. What is the difference between the optimum conditions, the zones of tolerance and the zones of stress?…

Abiotic and Biotic

A savanna grassland is an ecological system with scattered shrubs and isolated trees. The grasslands are found on both sides of the equator between tropical rainforests and desert biomes and have warm temperatures year round. A grassland savanna has a variety of biotic and abiotic components ranging from simple to highly specialized plants and animals and physical characteristics. The biotic components of a savanna grassland are the living organisms that inhabit the area. These organisms are referred to as producers, consumers or decomposers. Producers use the sun’s energy via photosynthesis to absorb nutrients. Trees, grasses, shrubs, mosses and lichens are types of producers found in a savanna grassland. Producers provide energy for many species of organisms such as insects, fungi,…

Biomes and Diversity

We as humans should be concerned with the extinction rate, because it is caused by human activities with toxics and polluntant chemicals that harm a healthy food flow in planting, and in fresh water. The loss of species will harm human and threat to human progress scientific studies can help prevent such loss. Also there are medical reasons as well, certain species on plants help to process opiates insulin and proteins to treat diseases. We should strive to continue the studies Ehlrich,1968 speaks of The Population Bomb meaning population growth will overwhelm food resources and supply and the conituing of the studies are said to be issues that are complex and with all people, states, countries need to develop scietific…

Ecology and Environment

1. Describe your local and surrounding ecologies and environments. Before we can describe the local and surrounding ecologies and environments, we have to know the meaning of ecology and environment. The relation among organisms and the environment that they are in is called ecology. During an organism’s lifetime, anything that affects it in any way is called an environment. Local and surrounding ecologies and environments in the local area that I reside in are trees, shrubs and vines, wildflowers and weeds, fungi (honey mushroom), lichen, fish, reptiles, amphibious animals, birds, mammals, insects, snails, and different worms. These ecologies require different habitats in the environment to survive and make their being. There are a few different habitats that exist in Northern…

Natural Resources

Adequate water supplies of high quality are necessary both for community use and local ecosystems. Communities and jurisdictions must work together to assure an adequate water supply to meet future needs. This section presents resources to aid in that effort. * Energy Communities require energy. Nonrenewable sources for power generation, home and workplace, and transportation cause pollution and its harmful impacts. Energy conservation and the use of renewable fuels provide cost-effective and more sustainable alternatives. This section contains resources available to make energy use more efficient. Air and Climate Both the natural ecosystem and human health can be adversely impacted by declining air quality and climatic change. Communities can preserve air quality by limiting or eliminating the discharge of harmful…

Macro Environmental Factors

Lancaster (2011) defines the macro environment as ’those global elements over which the organization has no control over but which affect the organization’s ability to serve its customers profitably.’ There are six major macro environment forces: cultural, demographic, economic, natural, political, and technological. The cultural environment includes institutions and other forces that affect the basic values, behaviours, and preferences of the society-all of which have an effect on consumer marketing decisions. The demographic environment includes the study of human populations in terms of size, density, location, age, sex, race, occupation, and other statistical information. The economic environment consists of all factors-such as salary levels, credit trends, and pricing patterns-that affect consumer spending habits and purchasing power. The (ecological) natural environment…

Ecosystem Structure Function and Change

Select a representative natural ecosystem in your area or one that you are interested in—such as a lake, preserve, or park—that is managed for native species. * The major structural and functional dynamics (processes) of that ecosystem including change over time The major structural and functional dynamics on Elizabeth River Parkway in Elizabeth, Union & Hillside, and Union County NJ regarding the ecosystem brought attention to local authorities, and many habitats on this area. Using the information from professional’s studies about how to help the ecologic; it is good to remember what happen with “Bio- Blitz 2008”. Why? On June 14, 2008, 10 teams of researchers and biologists, tally around 140 people, dispersed along Union County’s Elizabeth River Parkway in…

How do you define environmental science?

Environmental science is an interdisciplinary field that combines information from many disciplines, such as biology, geography, chemistry, geology, physics, economics, sociology (particularly demography, the study of populations), cultural anthropology, natural resource management, agriculture, engineering, law, politics, and ethics. Ecology, the discipline of biology that studies the interrelationships between organisms and their environment, is a basic tool of environmental science. Atmospheric science is a branch of environmental science that includes the study of weather and climate, greenhouse gases, and other airborne pollutants. Environmental chemistry examines chemicals in the environment, including soil and water pollution. Geosciences—for example, environmental geology and physical geography—study a wide range of environmental topics, such as soil erosion, groundwater use, ocean pollution, and climate. Scientists in these sub-disciplines…

Ecology

Patterns of plant successional change in Gatineau Park, Old Chelsea, were studied quantitatively. The relations between different successional stages of plant communities and abiotic factors were descried. To test these, we went to the fields, and worked on two transect in groups of 4. We counted the trees and measured the diameter at breast height (dbh) for tree with a dbh value greater than 2cm. The dbh measurements (cm), percentage of fern cover and percentage of bare ground were recorded and used to perform statistical analysis. No significant variations in the distribution of abundant tree species using chi2 analysis and percentage of fern cover using t-test analysis were observed between the compared sites. No significant variations found in the interquadrat…
