Developed countries are exploiting genetic resources and traditional knowledge from developing countries by patenting products derived from them without authorization or compensation. This is known as biopiracy. Examples discussed include patents granted on neem, turmeric, and basmati rice that were later revoked due to the traditional use and knowledge of these resources in their countries of origin. Biopiracy is criticized as being unfair and a threat to indigenous cultures by restricting local communities' use of their own traditional knowledge and resources. International efforts are working to establish laws protecting traditional resource use and knowledge.
