Environmental protection is important for several reasons, such as ensuring a lasting supply of resources, as well as providing access to clean food and water. Adequate environmental protection helps to reduce the risk of related health problems, such as asthma, and promotes a healthier environment in places where humans live, work and learn.
The environment plays an important role in a person's health, both short- and long-term. Examples include quality of the outdoor air along with water quality in the surface and ground as well as any toxic substances or hazardous wastes. Having a clean environment assists with prevention or control of disease, injury, and any disabilities that may arise from a poor environment. Approximately 25 percent of deaths and total number of diseases in the world are linked to environmental factors.
