There is a whole class of pollutants that are largely ignored by the laws: the man-made chemicals that have the side effect of acting like hormones in mammals.
A very few of them have been banned as carcinogens (a lesser threat) but NOTHING has been banned yet for acting like a hormone, and more of these chemicals are being invented every week, and NO tests are done to check for endocrine disruption.
A pollutant that acts like a hormone can interupt development in every stage of life from fertilized egg onward. Terrible things have been proven in wild life populations, with the effects spreading around the globe. Sterility, birth defects and all kinds of diseases in adult humans have been linked to the effects of these chemicals.
But despite warnings of scientists to manufacturers, nothing has been done. Plastics with that sort of chemical are still made into baby bottles and toys!
Manufacturers and corporations will not regulate themselves. They simply ignore and/or deny unpleasant facts about their products or practices until they are forced to change. $$$$$$ are everything. Relying on them to change to behavior that does not profit them will not work.
