The Advantages and Disadvantages of Genetically Modifying Crops.Summary: What are the advantages and disadvantages of genetically modifying food crops? Can developing countries or countries struggling with famine profit from these techniques?Does it affect the surrounding environment? These are all questions that have kept scientist biologist and ethicists busy. Religious groups would also like to have there say in it. Can genetic engineering help society, or will it be a burden for our future generations, because it has disastrous effects on our environment.Approximately 10,000 years ago the first crops were consciously planted. In the Middle East, wheat and barley were planted, the early farmers in Peru cultivated potatoes and beans and in the Indus valley the ancient civilization there started sowing their fields with rice. How they figured this out we don't know it was probably a long process of trial and error and a fair bit of luck. This early agriculture consisted out of four stages: sowing the seeds, caring for the plants, harvesting, selecting and keeping back some of the seeds for the next generation. Although these people that had settled down to farm had improved their life styles considerably, they still wanted a higher crop yield and a bigger variety of crops. This lead to certain techniques. Some that they understood like crop rotation, but others that have only been recently been explained by modern DNA research. These early farmers unconsciously crossed for example certain types of walnuts together, so that they were not poisonous anymore. Wild walnuts contain cyanide and the concentration in wild walnuts is enough to kill a human. These early farmers also tried to get bigger seeds and fruits of their crops and make them more resistant to diseases. Of course they booked some progress, but not a lot. Nowadays scientists are still trying to genetically modify crops using new techniques which involves cutting and pasting the DNA with enzymes. So is it only good that, because of the work of these scientists we will have stronger and healthier crops or are there also disadvantages to genetically modifying crops?One of the obvious arguments against genetically modifying crops comes from religious groups. They think that experimenting with DNA and genes is messing with the natural order. They believe that "God" created everything and meant it to be created that way. These religious groups can not prove that "God" meant it to be like this, so it is not valid evidence. Never the less they still make a point. If you genetically modify a crop in Area A these crops will of course also pollinate. When they pollinate there seeds will be carried by animals and the wind to the areas lying around them, Areas B, C, D and E. So if the grass in Area A was genetically modified than the seeds may carry and affect the grass in Areas B, C, and D and E which have normal natural grown grass. This of course could affect the ecological system that was in...
