Recently, Subway declared they would stop using a chemical because a food activist convinced people it was in yoga mats, and was therefore dangerous.
What's really dangerous are the toxic chemicals in solar panels. Soon, they could have the same ingredient as tofu, though you shouldn't stop eating tofu just because Vani Hari, the "Food Babe", can't pronounce any of the the chemicals it contains.
Cadmium chloride is currently a key ingredient in solar cell technology used in millions of solar panels around the world. This soluble compound is highly toxic and expensive to produce, requiring elaborate safety measures to protect workers during manufacture and then specialist disposal when panels are no longer needed.
