Earthworms consume and convert organic material into fertilizer in Hong Kong

Earthworms consume and convert organic material into fertilizer in a process called vermiculture run by Australia’s Sunburst Biotechnologies in Hong Kong October 23, 2007. Earthworms are known as nature’s recycling wizards and now the territory has recruited 80 million of them to help manage its waste. Hong Kong is one of the world’s most densely populated cities and environmental pollution—from industrial waste to poor air quality—is a serious concern. REUTERS/Bobby Yip (CHINA)
