To many people, genetically modified crops conjure up all kinds of strange visions from the future. One may think of gigantic vegetables or insects. Although this is not occurring, the future is here in the form of genetically altered foods. You will find good things and bad things about these foods, and here is more about what is genetic engineering and why many are concerned.

The main reason that plants are modified is to increase efficiency. One can get more crops from an acre of land. An abundant harvest means food prices will drop. When scientists alter plants genetically they change the DNA to create a plant that is not affected by common disease or blight. History is full of plant disease that causes great famine, and this may be avoided.

Many kinds of genetically modified crops or GMO plants can survive in difficult conditions. Some years may enjoy an abundance of rainfall while others may have long drought periods. GMO crops can be modified to produce plants that do not need a lot of water.

When something has been altered from a DNA level side effects are not uncommon. For instance, a superior plant may also contain toxins. Many people may be allergic to these new kinds of altered foods.

If one creates super plants that are resistant to modern day pesticides it would seem like a good thing. Farmers can spray their crops and kill only weeds or insects. However, weeds and insects are far more resilient than most people realize. Within a few years time, super bugs and super weeds appear that are immune to pesticides. This creates serious problems.

When you closely examine the question what is genetic engineering you will see pros and cons. The main problem is, a lot of consumers are unaware that these crops have been altered. With GMO labeling, people can decide if they want these products or not.
