Water
The water supply in the USA! Is far from safe! It now has many unrecognized chemicals that we have no clue how toxic they are being continually pumped into the ground all over the USA by fracking, by Industrial Transnational Corporate Farming using huge amounts of fertilizers and pesticides and by Overtly large industrial Animal farms using antibiotics and growth hormones which enter the aquifers, creeks, streams, lakes, rivers, then the oceans!
