I have called this phenomenon of stealing common knowledge and indigenous science "biopiracy" and "intellectual piracy." According to patent systems we shouldn't be able to patent what exists as "prior art." But the United States patent system is somewhat perverted. First of all, it does not treat the prior art of other societies as "prior art." Therefore anyone from the United States can travel to another country, find out about the use of a medicinal plant, or find a seed that farmers use, come back here, claim it as an invention or an innovation.
Vandana ShivaThe enclosure of the biological and intellectual commons in this way is a real threat to the future of people everywhere because it creates a situation where common practices that have been part of people's lives for generations become monopolies of a handful of pharmaceutical, agribusiness and agrichemical corporations. People then become incapable of looking after their own needs.
Vandana ShivaThere are scarcities in drinking water when you pollute the groundwater with nitrates. There is a scarcity in diversity when you create huge cornfields with the same strain of corn so that when one disease strikes - which happened in the United States in the 70s - all the cornfields in the country are wiped out. That was the first time the U.S. realized the value of diversity in agriculture and began to discuss genetic resources and their conservation.
