As spring sports get under way, another rite of the season begins: complaints about the dangers of artificial turf. Georgia State University environmental health scholar Stuart Shalat explains why crumb rubber, an ingredient that helps support the blades of fake grass in artificial turf, “should not be a first choice material for children to play on.”
Reflecting on years spent traveling along the U.S.-Mexico border, Michael Dear, a regional planning expert at UC Berkeley, writes about the ties between communities on each side. The sense of connection is so deep that “people assert that they have more in common with one another than with citizens of their countries.”
And climate scientist Robert Kopp, who studies sea-level rise, provides a unique book review of “New York 2140,” a novel set in a world where the oceans have risen 50 feet from global warming.
