Going from history to convincing, how is that possible? History consisted of the general topic, and now itís time to move on to the convincing. This can be done by a transition paragraph. The paragraph would summarize the history and introduce the new paragraph of your convincing.
Soybeans are one of the crops that are being genetically modified. Since 1997 GMO soybeans are being used in an increasing number of products. There's a lot of controversy around GMO soybeans. However, GMO soybeans have never caused any harm to people. The possible negative aspects of GMO are more of environmental and economic nature: dependence of farmers on a few multinationals and contamination of wild plants.
It summarizes up that soybeans are being genetically modified and introduced some concerns people are have about consuming the product. The transition paragraph was used to make the paper move smoothly and not just jump into a new topic without knowing where it was coming from. They could have summarized more, instead of telling more of the history while introducing the controversies.
