KFC has been criticised on different issues. Greenpeace accused KFC of destroying the Amazon Rainforest. This is because KFC bought their soy they use for chicken food from Cargill. The soy has been traced back to the European KFC. Cargill has reportedly been exporting soy illegally for several years. The Greenpeace organization researched the issue and brought it to the attention of the parent company YUM! Brands, Inc. The parent company denied the illegal operation, and said that their supply of soy is grown in parts of Brazil. Greenpeace has called on KFC to stop purchasing soy from Cargill, to avoid contributing to the destruction of the Amazon.
