The ocean is turning more acidic as CO2 emissions rise, and shellfish are struggling to survive in the more acidic sea.

A tiny, seldom seen bird is discovered alive and well in an unexpected place. Join a biologist who spent more than 300 days tracking dozens of elusive pygmy owls in the middle of city of Portland. They live in Forest Park. Portland hopes to capture some of the 10 billion gallons of rain that flows off 12,000 acres of roofs in the city by promoting eco-roofs. The city and Oregon State University find roofs covered in plants and soil soak up and hold 40 to 55% of the rain that would normally run down storm drains.
