Blog Assignment #1: Selection 32, Summary

Our Stolen Future
Theo Colborn, Dianne Dumanoski, and John Peterson Myers
"Our Stolen Future" talks about the exposes humans and animals to harmful man made chemicals.  We are mammals that share a common environment, evolutionary legacy and contamination of synthetic chemicals(environmental endocrine disruptor) and because of the commonalities, animals have become a test subject for a synthetic hormone drug called diethylstilbestrol (DES).  These synthetic chemicals that we breath and absorb in causes disturbance in our(and the animals) hormones.  

Endocrine disruption comes from farm fields and industrial pollution.  This problem that suddenly surface puts humans, and wildlife/laboratory animals are at risk.  It causes abnormalities of genital in children.  Therefore scientists have issued a "Wingspread Statement" which is an urgent warning to humans about the consequences of being exposed to these chemicals can disrupt the balance of embryonic development and the damage will last unless if chemicals are controlled.  

This began the experimentation of DES which will hopefully fix the disruption of hormones, but studies shows that DES is an unstable drug and it causes abnormalities in the children of the mothers that took the drug during pregnancy.  Animals are used in for this experiment because they are able to mature and reproduce faster than humans; and because our hormone development is similar we are more likely be able to tell early signs and warnings.
