Pediatrics is the branch of medical science dealing with children and their diseases.
A number of diseases in children are related to unsafe environments.
The environment plays important role on children health that is more vulnerable
to diseases due to following reasons:

• Exposure to certain toxic chemicals can result in irreversible damage, as well as
to diseases during adulthood.
• Their immunity, digestive system, reproductive systems, and central nervous
system are more vulnerable compared to adults.
• They are in an active state of growth.
• They are more exposed through hand-to-mouth activities due to innocence and
ignorance about consequences.
• As children have smaller lungs, they breathe more air in proportion to their
weight.
