A political activist and environmentalist named Mark Lynas spent much of his life protesting the use of genetic modifiers in the development and growth of food products. He did so because he thought that their use was harmful to the environment, but this standpoint was not based too much on actual science.

He has since changed his mind on GM food products, and has apologized publicly for his years of protest. He now understands that these GM foods need less pesticides and other chemicals necessary for the production of Non-GM food; meaning that the Non-GM food products do more harm to the environment than the GM food products do.

Because he has listened to science instead of personal morality, and made a public apology for his previous activism, he has brought attention to the benefits of GM foods to the public. People doing things like this are great for improving the knowledge of the common person.
