The Maya ICBG bioprospecting controversy took place in 1999–2000, when the International Cooperative Biodiversity Group led by ethnobiologist Dr. Brent Berlin was accused of engaging in unethical forms of bioprospecting (biopiracy) by several NGOs and indigenous organizations. The ICBG had as its aim to document the biodiversity of Chiapas, Mexico and the ethnobotanical knowledge of the indigenous Maya people – to ascertain whether there were possibilities of developing medical products based on any of the plants used by the indigenous groups.
