Good News Bears: Urban-dwelling females, eating a garbage-fortified diet, gain weight faster and have cubs younger than their forest-dwelling counterparts, according to a study in western Nevada led by the Wildlife Conservation Society.
Bad News Bears: Urban females die younger.
Worse News Bears: Despite their reproductive head start, urban animals aren't increasing the overall bear population. Any gains are more than offset by urban hazards, especially collisions with cars. Says the lead researcher: "Urban areas are becoming the ultimate bear traps."
