More of the same from GMO giant Monsanto -- at an annual shareholders meeting on Tuesday, the company voted not to explore potential "financial and legal risks."

Harrington Investments proposed a study to investigate how the genetically-altered seeds could impact the environment. Monsanto's seeds contain patented material, and if a law suit were to unfold, it could severely affect the company.

Harrington CEO John Harrington expressed concern over "genetic drift," where GMOs cross pollinate with traditional or organic seeds.

Monsanto said in a statement the study would "be redundant and provide no meaningful additional information."

Several groups protested outside the annual meeting in Creve Coeur, including Harrington Investments.
