Now, new research suggests that atrazine may be dangerous at lower concentrations than previously thought. Recent studies suggest that, even at concentrations meeting current federal standards, the chemical may be associated with birth defects, low birth weights and menstrual problems.
Scooter thing: See if you can figure out what this contraption is all about. Someone sent it Kevin Kelly’s way.
