All of the physical, chemical, and biological conditions that together act on an organism or an ecological community and influence its growth and development. Soil, air, water, climate, plant and animal life, noise level, and pollution are all components of an environment. To survive, organisms must often adapt to changes in their environments.
The sum total of all surroundings of a living organism, including natural forces and other living things, which provide conditions for development and growth as well as of danger and damage. See also environmental factors
The environment is something you are very familiar with. It’s everything that makes up our surroundings and affects our ability to live on the earth—the air we breathe, the water that covers most of the earth’s surface, the plants and animals around us, and much more.
In recent years, scientists have been carefully examining the ways that people affect the environment. They have found that we are causing air pollution, deforestation, acid rain, and other problems that are dangerous both to the earth and to ourselves. These days, when you hear people talk about “the environment”, they are often referring to the overall condition of our planet, or how healthy it is.
