Introduction

Land management has preserved the natural characteristics of Hopetoun Falls, Australia while allowing ample access for visitors.

The natural environment encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components:

In contrast to the natural environment is the built environment. In such areas where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human , hence beaver dams, and the works of mound-building termites, are thought of as natural.

People seldom find absolutely natural environments on Earth, and naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different.

Natural environment is often used as a synonym for habitat, for instance, when we say that the natural environment of giraffes is the savanna.

Natutal environment and us

Leo Tolstoy once said,"one of the first conditions of happiness is that the link between man and nature shall not be broken."

What makes natural environment

Everything that surrounds us the earth, the air ,food chains ,plants, animals ,other humans,water,sky and so forth-Max our natural environment. The natural environment affects our lives, the lives of all living beings.

The natural environment has two

s-b-categori : the living environment and the non living environment. the plants ,animals, human beings and other living organism together form the living environment the non living components such as while oil/rock, air, water and sun together form the non living environments. (Full article...)

A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment.

The term environment can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. (Full article...)

A view of the Earth from space.
Achieving sustainability will enable the Earth to continue supporting life.

Sustainability is the ability to exist constantly. In the 21st century, it refers generally to the capacity for the biosphere and human civilization to co-exist. It is also defined as the process of people maintaining change in a homeostasis balanced environment, in which the exploitation of resources, the direction of investments, the orientation of technological development, and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations. For many in the field, sustainability is defined through the following interconnected domains or pillars: environment, economic and social, which according to Fritjof Capra, is based on the principles of Systems Thinking (See also Systems theory). Sub-domains of sustainable development have been considered also: cultural, technological and political. According to Our Common Future, sustainable development is defined as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs." Sustainable development may be the organizing principle of sustainability, yet others may view the two terms as paradoxical (i.e., development is inherently unsustainable).

Sustainability can also be defined as a socio-ecological process characterized by the pursuit of a common ideal.

An ideal is by definition unattainable in a given time and space. However, by persistently and dynamically approaching it, the process results in a sustainable system. Many environmentalists and ecologists argue that sustainability is achieved through the balance of species and the resources within their environment. As is typically practiced in natural resource management, the goal is to maintain this equilibrium, available resources must not be depleted faster than resources are naturally generated.

Oil-spill.jpg

An oil spill is the unintentional release of liquid petroleum hydrocarbon into the environment as a result of human activity. The term often refers to marine oil spills, where oil is released into the ocean or coastal waters. Oil can refer to many different materials, including crude oil, refined petroleum products (such as gasoline or diesel fuel) or by-products, ships' bunkers, oily refuse or oil mixed in waste. Spills take months or even years to clean up.

John Muir c. 1902

John Muir ( MEWR; April 21, 1838 - December 24, 1914) also known as "John of the Mountains" and "Father of the National Parks", was an influential Scottish-American naturalist, author, environmental philosopher, botanist, zoologist, glaciologist, and early advocate for the preservation of wilderness in the United States of America.

His letters, essays, and books describing his adventures in nature, especially in the Sierra Nevada, have been read by millions. His activism helped to preserve the Yosemite Valley and Sequoia National Park, and his example has served as an inspiration for the preservation of many other wilderness areas. The Sierra Club, which he co-founded, is a prominent American conservation organization. In his later life, Muir devoted most of his time to the preservation of the Western forests. As part of the campaign to make Yosemite a national park, Muir published two landmark articles on wilderness preservation in The Century Magazine, "The Treasures of the Yosemite" and "Features of the Proposed Yosemite National Park"; this helped support the push for U.S. Congress to pass a bill in 1890 establishing Yosemite National Park. The spiritual quality and enthusiasm toward nature expressed in his writings has inspired readers, including presidents and congressmen, to take action to help preserve large nature areas.

Logo of Greenpeace

Greenpeace is a non-governmental environmental organization with offices in over 55 countries and an international coordinating body in Amsterdam, the Netherlands. Greenpeace was founded in 1971 by Irving Stowe and Dorothy Stowe, Canadian and US ex-pat environmental activists. Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its diversity" and focuses its campaigning on worldwide issues such as climate change, deforestation, overfishing, commercial whaling, genetic engineering, and anti-nuclear issues. It uses direct action, lobbying, research, and ecotage to achieve its goals. The global organization does not accept funding from governments, corporations, or political parties, relying on three million individual supporters and foundation grants. Greenpeace has a general consultative status with the United Nations Economic and Social Council and is a founding member of the INGO Accountability Charter, an international non-governmental organization that intends to foster accountability and transparency of non-governmental organizations.

Greenpeace is known for its direct actions and has been described as the most visible environmental organization in the world. It has raised environmental issues to public knowledge, and influenced both the private and the public sector. The organization has received criticism; it was the subject of an open letter from more than 100 Nobel laureates urging Greenpeace to end its campaign against genetically modified organisms (GMOs). The organization's direct actions have sparked legal actions against Greenpeace activists, such as fines and suspended sentences for destroying a test plot of genetically modified wheat and damaging the Nazca Lines, a UN World Heritage site in Peru.

Along with several other NGOs, Greenpeace was the subject of an improper investigation by the US Federal Bureau of Investigation between 2001 - 2005. The Inspector General of the US Justice Department determined that there was "little or no basis" for the investigation and that it resulted in the FBI giving inaccurate and misleading information to the United States Congress.
