China, Brazil, India, and nine other of the world's most biodiverse countries signed an alliance Monday to fight biopiracy and press for rules protecting their people's rights to genetic resources found on their land. The declaration — also signed by representatives of Indonesia, Costa Rica, Colombia, Ecuador, Kenya, Peru, Venezuela, and South Africa — echoed complaints long voiced by Indians and environmentalists: that wealthy nations are "prospecting" for species in order to patent or sell them without offering concessions or benefits for local people.
