Modified Organisms were developed in the mid-1990s. Since they were first created‚ there have always been people who have been against them. These people have made false claims using faulty scientific researches. This research paper will prove that Genetically Modified Organisms should not be feared and should be widely used around the world. This will be done by proving that Genetically Modified Organisms do not present health hazards‚ reduces the impact of the environment‚ and makes food more available
