Thalidomide Baby
In the 1950's and 60's women in many
countries prescribed thalidomide as a sedative
and to help with morning sickness. The drug
causes terrible birth defects and the children
of pregnant women taking the drug were often
born with horrible malformations including
shortened arms, hands extending directly from
the shoulder, and the absence of the thumb
and the adjoining bone in the lower arm.
15,000 children worldwide were born with
these serious defects before the drugs were
pulled off the market.

Ozone



The ozone layer reflects or absorbs 99% of damaging UV rays
from the sun, preventing them from reaching the earth’s surface.
However, pollution is compromising the ozone layer allowing
more and more of the UV rays to reach the earth’s surface.
The ozone layer is a protective covering that surrounds most of
the earth and protects us from harmful UV rays. It has three
oxygen atoms, rather than two oxygen atoms like the form of
oxygen we breathe during respiration.
There are a number of activities and events that cause ozone
destruction.

HIV can be passed from mother to child during
delivery. About ½ of infected mothers will pass HIV to
their child during childbirth
Newborns of crack cocaine mothers are born addicted
to the crack. They experience tremors, seizures, and
other withdrawal symptoms.
Gonorrhea and syphillis are transmitted to the eyes of
the newborn causing blindness.
Some STDs have no cure and are common (e.g.,
genital herpes).
