A worker holds some New Zealand spinach after he picked it from a greenhouse at an organic farm located on the outskirts of Beijing June 20, 2008. The farm, one of around 500 organic farms in China, grows fruit and vegetables for mainly foreign markets such as Japan, Malaysia and the United Kingdom. However during the Olympic Games in August, they will be supplying produce to official caterers. REUTERS/David Gray (CHINA)
