Harmful chemicals abound in tons of household products (a lot of which are products relating to the cosmetic industry, suprise suprise) that can really mess with your reproductive system according to a number of sources:
The Battle over BPA by Amie Newman
Toxic Chemicals: Neglected Threats to Health and Reproduction by Jennifer Rogers
This has become my personal product bible: Skin Deep Cosmetic Safety Database
Also...contrary to popular belief, I think most people for reproductive rights aren't involved in Earth Day because of the whole population control thing, which is actually kinda racist and classist...and sexist.
