EVIDENCE: For example, "As more plants and crops can be grown and at more areas, including those that were previously unsuitable for farming, oxygen in the environment is increased, decreasing the proportion of carbon dioxide and, in turn, reducing global warming” (Advantages and Disadvantages of GMO's).
COUNTERCLAIM - (Rebekah Weldele): True, but compared to all the cars, airplanes, and vehicles polluting the air, along with everything else, how effective will these plants really be? How much of a dent will the plants make in the environments?
COUNTER ARGUMENT(Esmeralda Robles): It doesn't really have to be really effective, but it will decrease a good amount and if it continues it will decrease even more, it will probably need to take time.
