As you have read there are a number of factors that can cause damage during the prenatal stages. These teratogenic effects vary a great deal from individual to individual. Of course, this can be affected by the timing, duration and the amount of exposure. In addition, when a developing child is exposed to a combination of teratogens they can interact to increase the likelihood of developmental damage.
The question for you to consider is: If given the opportunity to warn a pregnant woman (or a group of pregnant women) about the dangers of one particular teratogen, which teratogen would you choose? In your post, you should use and cite information at least 2 sources (from your readings and/or outside sources) to justify your choice. I encourage you to think about this question at both the individual and societal/cultural levels. What that means is that although it is perfectly reasonable to consider which substance/situation has been shown to impact an individual’s development greatest, it is also important to consider other things like the availability of the substances and how knowledgeable the masses are about the dangers of a particular teratogen. For example, even if you think that plutonium is the substance that has the potential to cause the greatest developmental problems, the fact that we are highly unlikely to come into contact with it may justify choosing something else.
