Diseases

Reference: http://en.wikipedia.org/wiki/Disease

Summary: A disease is an abnormal condition that affects different organisms. Depending on the disease, there will be different side affects and symptoms. It is like a illness or disorder. There are different types of stages to each disease. There are four main types of disease: pathogenic disease, deficiency disease, hereditary disease, and physiological disease.

Critique: My opinion about diseases is that they are bad. If I could I would get rid of all of them.

Impact: The impact of diseases is very negative. The impact it has on humans is a bad one because it can kill us.
