Predators as climate helpers

By Janet Raloff / February 18, 2013

This freshwater stickleback eats the tiny animals in stream water that graze on plants and algae. This predation allows those plants and algae to collect and store carbon, rather than letting it escape into the atmosphere. Credit: Nicole Bedford, UBC
