What Is Environment?

Environment is the physical surroundings in which we live. It can either consist of living factors or non-living factors. The environment provides us with conditions that facilitate growth and development and also with a risk of damage and danger. It consists of everything real around us such as sunlight, soil, air, water, rains, mountains etc. The surroundings we dwell in is subjected to constant change, these factors are majorly contributed by human activity. For instance, climate change. A constant balance needs to be maintained as all the components of the environment are correlated where a change in one component has a certain impact on other components eventually, if not immediately depending upon the severity.
