The average American eats the equivalent of a credit card-sized amount of plastic a week! 
According to a 2018 report released by The National Ocean Service (a part of the U.S, Department of Commerce) “about 300 million tons of plastic is produced globally each year”. Only about 10 percent of that is recycled. Of the plastic that is simply trashed, an estimated eight million tons ends up in the sea each year.  And it winds up in the flesh of the fish you eat.
Researchers at the National University of Ireland in Galway have been studying ocean fish in the North Atlantic to find out how much plastic is in their flesh. They discovered that “73 percent of 233 deep-sea fish” contain microplastic, or small plastic pieces less than 5 millimeters long. 
Children who consume even small amounts of lead in drinking water lose IQ points for life. In addition, lead in children’s brains (shown here in orange) reduces their impulse control. Individuals with lead in their brains are imprisoned at four times the rate of their generation who have no lead. 
Surprisingly, there are no federal requirements for schools to test their drinking water for lead contamination, and only 7 states require any form of inspection at all; you can click here to see that list.
No one checks the schools in the other 43 states!
Almost no educators understand how school buildings can undermine the success of both students and teachers. Lack of fresh air lowers brain function – leading to lower standardized test scores, even among the brightest students.
Generally speaking, there are four generations of school buildings. All have unique features that either help learning, or hurt it. In the oldest generation of buildings, there is no machine to bring in fresh air. If you wanted the kids to get fresh air, you either opened a window, and/or a hallway door, or you sent them outside. Now the windows are nailed shut for security and caulked to save energy, the kids eat in the cafeteria, often have recess in the gym, and take a bus home. And their brains do not work well.
