Greenpeace this week released a report on soil and rice crops sampled in villages close to a concentration of heavy metals smelters in China's Hunan Province, "an area that ranks first in rice output and among the top five in nonferrous metals production." The results showed that both rice and soil near the industrial complex are contaminated by heavy metals, including lead. "12 out of all 13 rice samples contained excessive levels of cadmium." Read the "Cadmium rice" report at Greenpeace East Asia. Here's a related piece at the New York Times.
Golden Rice is a strain of rice genetically engineered to produce extra beta-carotene, part of a humanitarian effort to get more Vitamin A into the diets of people who subsist primarily on rice. The genes that produce the beta-carotene come from corn and a soil bacterium. On the legal end, the rice was developed using free technology licenses that allow the International Rice Research Institute to hand the rice out for free to subsistence farmers, and allow those farmers to save seeds and replant in subsequent years. Last week, anti-GMO activists destroyed a test plot of Golden Rice in the Philippines.
