Degrades the immune system (the system that protects us all from bacteria,
viruses and cancers);

Interferes with our hormones, reducing sperm production, masculinizing
female rats, altering the development of baby rats (changing their bones,
thymus, and nervous systems), modifying their adrenal and reproductive
hormones;

Causes serious, permanent impairment of the nervous system in diesel-exposed
railroad workers;

Induces allergic reactions, not limited to asthma, causing children to miss
thousands upon thousands of school-days — a primary cause of school dropout,
consequent low self-esteem, and subsequent life- failure.
