It's been almost 100 years since William Mulholland stood atop an aqueduct along the Owens River and said, "There it is, take it." He was referring to a diversion channel that started piping water to Los Angeles from 200 miles away. That water allowed L.A. to become the metropolis it is today.
But it also meant that the Owens River no longer flowed into the massive Owens Lake, which quickly dried up and became one of the biggest environmental disasters in the nation.
Many of the drugs we take aren't actually digested â€” they pass through our bodies, and down through the sewer pipes. Traces of those drugs end up in the bodies of fish and other wildlife. Nobody's sure what effect they have.
