NASA has reactivated a mothballed spacecraft to look for big objects that might strike Earth. It's part of an increased effort to find potential hazards — but some scientists sizing up the sky think we should try harder.
Weasel-like fishers, spotted owls and other small predators have become collateral damage as illegal marijuana growers push deep into remote forests of Northern California. Biologists warn that the heavy use of insecticide and rat poison to protect crops is pushing some wildlife species to the edge.
