Environmental Aspect and Impact
~Dr Dilip Ganguly

Environmental Aspect and Impact: The Basics

In the study of environment, it is essential to identify each possible environmental aspect and impact of it on our surroundings. The various environmental aspects each have a number of different impacts on the environment. Potential impacts must also be identified.

1. Commonly Used Definitions in the Study of Environmental Aspect and Impact
1.1. Environmental Impact Any change to the environment whether adverse or beneficial (wholly or partially) resulting from an organization's activities products or services.
1.2. Significant Impact The activity that results in substantial breach of statutory regulations under abnormal conditions.

Knowledge of environmental aspect and impact is necessary in order to have a thorough awareness of the world we live in.
