Question

Write the factors affecting the environment.

Answer 1

Hint: An environment is defined as one’s surroundings or condition in which a person, animal or plant survives or operates. This environment is constantly changing, and with these changes, we need to become increasingly aware of the environmental issues.

Complete answer:
There are many factors that affect the environment. Some of them are as follows:
> Trees: Trees absorb large amounts of $CO_2$ and release oxygen. Thus, they are very important for the proper functioning of this environment.
> Population: Overpopulation affects the environment in many ways. It increases pollution density and diminishes natural resources.
> Greenhouse Effect: Greenhouse gases like $CO_2$, methane, etc. trap the heat from the sun and increase the temperature of the earth.
> Natural and technological disasters like the burning of forests, oil spills in oceans also cause large scale pollution and harm to the inhabitants of forests, water bodies, etc.
> Pollution: It is one of the most severe factors affecting our environment adversely nowadays.
> Natural disasters like floods, tsunami, etc. cause huge loss of life and resources.
> Climate change- It is a great concern in today’s scenario. This problem has surfaced in the last few decades. Greenhouse gases are the major cause of climate change. It also results in the melting of glaciers, change in seasons, epidemics, etc.

Note: The most devastating effect of the greenhouse effect is the Ozone layer depletion. The ozone is a layer of concentrated ozone gas. It prevents the sun’s harmful ultraviolet rays from reaching the earth. It is continuously being destroyed by CFCs (chlorofluorocarbons), which are used in industries and everyday life (e.g. aerosol cans). This causes exposure to the harmful ultraviolet rays resulting in several skin diseases including cancer.
