While most people focus on viruses as pathogens, many viruses are vital to ecosystems. Bacteriophages can protect plants and animals by killing the bacteria that can harm them. Also, viruses in the oceans are key to decomposition, which in turn leads to marine flora consuming about 3 gigatons of carbon dioxide that would have otherwise been released into the atmosphere. And researchers are looking at viruses to deliver therapies in many areas of medicine. (Source: Encyclopedia of Life, accessed online Aug. 27.)
