Natural environment encompasses all living matter and non-living matter that is naturally in the earth. In its purest sense, it is an environment without human activities. His opponent for the word "nature" is "built environment".
For some, there is trouble on the term "natural" because most of the natural environment, human influence at one time or another, either directly or indirectly. To overcome this problem, the influence of man consented without causing any landscape excluded from the status of "natural". Biasanyan, the meaning of this term depends on the context more than the specified definition. Many natural environment is the result of the interaction between nature and humans. By this reason, the term "ecosystem" was used to describe an environment that contains nature, including the human. Based on this, the problem of the environment is human or social problems. There are some people who consider the separation of "environment" of the "human" is very dangerous. This is a general understanding that has been the basis of environmentalism, which is the movement of political, social and philosophical, and the support of a wide range of actions and policies to cover any remaining natural environment, or restoring and expanding the role of nature in this environment. Although increasingly rare wilderness, wild nature (eg, forests that are not handled, not worked grasslands, wildlife and wildflowers) can be found in many places the first human occupation.
Goal is usually expressed by astronomers environment include:
reduction and man-made pollution cleaning with the goal of zero pollution in the future;
reduction in fuel consumption is not renewable and alternative development consisting of plants, material low carbon or renewable energy sources;
conservation and utilization of depleting resources that may be permanent, such as water, land and air;
protection of representative ecosystems, unique or original;
preservation and development of endangered species or ecosystems from extinction;
establishment of nature reserves and biosphere under various types of protection, and
in most generally, the protection of biodiversity and ecosystems needed by all human beings and other life forms on this planet.
Recently, there is a concern that so deeply about climate change caused by greenhouse gas antroprogenik emissions, especially carbon dioxide, and its interaction with human use and nature. Efforts have been devoted to the reduction of greenhouse gases that cause climate change (ie, through the "Climate Change Convention" and the "Kyoto Protocol") and the creation of adaptation strategies to assist species, ecosystems, people, countries and regions to adapt to the change- climate change.
