Contrary to popularly held beliefs, GMOs approved by the government are not really safe for public consumption as agencies rely on incomplete and manipulated reports from the biotech companies in giving these approvals. A report from the Union of Concerned Scientists (UCS) states that corporations use five basic methods to influence scientific and policy making, corrupting the process by intimidating scientists and twisting results to suit their interests. Shaping public perception through the media, restricting agency effectiveness, influencing congress and exploiting judicial pathways to bully and silence scientists. In 2009, 26 university entomologists wrote a letter to the EDA noting that " no truly independent research can be legally conducted on many critical questions involving GE crops." Research materials are difficult to get and when accessed, you can't publish without the corporation's permission invariably, "agritech companies have given themselves veto power over the work of independent researchers" stated a Scientific America editorial. Government agencies give approvals based on unreliable reports submitted by the corporations themselves as they create harsh conditions for independent researchers to thrive.
