Definition of theme - Environment.

Environment is the surrounding atmosphere and condition for existence. It is an essential natural process or an outcome of occurrence. There are two types of environment, one is negative and the other is positive.

The negative and positive factors have to join together to form an environment. For example, mother and father to give birth to a child and the negative of energy and the positive of energy are joined together to produce electricity. In the system of environment, both negative and positive factors have integral role to play. 

My understandings:

Surrounding atmosphere and condition: Such as the amount of oxygen and the amount of sunlight for living things to grow and stay alive, etc.

Negative and positive factors: Our environment has both negative and positive factors and when both come together, something that is new will be form.

Environment is he complex of social and cultural conditions affecting the nature of an individual or community. It is ever-changing. 

My understanding: Environment will never be stagnant because our social and cultural conditions are always changing from time to time. Some examples of social and cultural conditions are, there are different races living in our society, so our environment is a multi-racial environment and hence, we have to know each other's cultural background and respect one another. Also, environment may not be the environment we live in, but different industries have different marketing environment too.

There are two types of factors in our environment, one is negative and one is positive. Both have to join together to complete the environment. Environment is the setting of our community and the nature of individual.
