Sea otters returned to a polluted California estuary in 1984; eelgrass expanded 600%, while marsh-edge erosion later slowed by 69% on average

Sea otters returned to California’s Elkhorn Slough in 1984 when pollution had severely affected its ecosystem. When sea otters returned to California’s Elkhorn Slough in 1984, the estuary was already facing severe environmental pressure. The coastal wetland had high nutrient levels linked to its agriculture-dominated watershed, while eelgrass had fallen to an all-time low of … Read more

Meet Tina Jin, the 15-year-old Massachusetts student who turned animal bones into a new material for cleaning polluted water

A 15-year-old Massachusetts student is exploring an unusual way to make polluted water cleaner: using discarded animal bones. Tina Jin, a student at Phillips Academy in Andover, developed a filtration system that uses ground cow, lamb or pig bones arranged in multiple layers to target different contaminants in water. Her research focuses on places where … Read more
