A Brief Introduction To Environment Variables
Environmental science is concerned with the study and explanation of environmental influences and their effects on human health, the environment, and human society. These influences can take different forms and have a variety of underlying causes. An important focus of this field is the study and description of the influences on human health and society. Many different types of research and studies are done on the subject including data analysis, research design, survey, case studies, modeling, research synthesis, and interdisciplinary projects.
The natural environment includes all living things and nonliving things happening naturally, which means in this context not artificial. The terms are used to describe the Earth or parts of the Earth in relation to its environment. It also includes the processes, principles, and factors that control its development and maintenance. Some natural environments may be referred to as ecological, socio-ecological, and physical environments. These include the global, regional, national, and local environments.
The human activities that affect the environment are known as the sources of environmental pollution. These are the products of energy, land, water, and solid waste. They may be caused by humans, nature, and biosphere objects. One type of nonliving things that can be affected by human activities is the living things. This also includes aquatic organisms, soil biological cycles, and the global atmospheric processes.
There is much debate on the definition of an environment. Some people believe that the word environment is not used commonly enough to describe the totality of the living world and that it encompasses all aspects of the planet’s ecosystems, life, structure, and forces. According to these people, the word environment should be reserved for the term ‘living world’, which encompasses all the living things of the planet. Under this umbrella, there would be different categories that overlap one another.
A very important part of the environment is the natural environment. This includes the external factors such as the temperature, precipitation, winds, cloud composition, landforms, and the UV radiation. Another important aspect of the natural environment is the internal environment variables. These include the internal processes such as Photosynthesis, aerobic metabolism, chemical reaction, nuclear reaction, and bacterial respiration.
The combined effect of the internal and external environment variables on a specific system is termed as the total environmental impact. A summing up of all these effects produces the Earth’s environmental quality. A number of new techniques and models have been developed to evaluate the Earth’s environment variables. The results of these studies form the basis of the studies conducted on the mitigation of environmental impacts.
