Introduction to Environmental Concepts

“The environment” refers to any set of physical and biological features that exist in the Earth’s crust, atmosphere, and space. The environment is made up of everything living and non-living things that occur naturally, which means outside of human existence. The phrase most often is used to describe the Earth or parts of the Earth. The environment is made up of the earth, oceans, atmosphere, ice, land, and solar system.

An environment can have a starting point, which is the place where everything began and everything ended, an initial value that represent the value of everything that has ever occurred and will ever occur, and a reference point that is a general description of the environment. The environment can also be a definition, which gives an overall summary of how everything about the environment work together, how it is presently arranged, and what it could be like if everything changed radically. In many cases, people talk about starting values and end values in the context of the environment as a whole, which is something like starting a business and giving a yearly budget and an overall description.

All types of physical variables are included in the environment, and all of these variables interact with one another. A few of these variables are called external variables, while all other variables are called internal variables. External variables include any external forces that change the environment, such as earthquakes, volcanoes, and falling objects. Internal variables are things within the environment that cause changes in the environment, including humans who affect the environment through their activities.
