Document Summary

There is not testing on chemicals before they become used chemicals are safe until proven otherwise. Our bodies mistake these chemicals for hormones, they can act on or disturb these levels in the body. In order to achieve normal levels during development these levels must be controlled, these are not recognized by the body as estrogen so they can get into the placenta and act on the baby as if they were estrogen. Animal research is used because its hard to see these links on humans. In humans we can see correlation, but in animals we can see causation. Testicular cancer rates increase at a fast rate showing its being caused in the environment. People are diagnosed at age 30 but the start can be traced back to the womb. Puberty can be started earlier due to spikes in estrogen levels from chemicals. Exposure is also related to reduction of iq of 5pts.
