Environment is living things and what is around them. It includes physical, chemical and other natural forces. Living things do not simply exist in their environment. They constantly interact with it. Organisms change in response to conditions in their environment. In the environment there are interactions between plants, animals, soil, water, temperature, light, and other living and non-living things.
The word 'environment' is used to talk about many things. People in different fields of knowledge (like history, geography or biology) use the word differently. An electromagnetic environment is the radio waves and other radiation and magnetic fields. The galactic environment refers to conditions between the stars.
In psychology and medicine a person's environment is the people, physical things, places, and events that the person lives with. The environment affects the growth and development of the person. It affects the person's behavior. It affects the person's body, mind and heart.
Natural environment[change | change source]
In biology and ecology, the environment is all of the natural materials and living things, including sunlight. This is also called the natural environment. Some people call themselves environmentalists. They think we must protect the environment, to keep it safe. Things in the environment that we value are called natural resources. For example, fish, sunlight, and forests. These are renewable natural resources because they come back naturally when we use them. Non-renewable natural resources are important things in the environment that are limited for example, ores and fossil fuels.
Nowadays the environment is polluted with harmful gases.
Historical environment [change | change source]
Environment is the events and culture that a person lived in. A person's beliefs and actions are dependent on his environment. For example, Thomas Jefferson and Julius Caesar owned slaves. Modern people mostly think it's wrong to own slaves. But in Jefferson's and Caesar's environments slavery was normal. So, their actions did not look as wrong in their societies.
