Our current food supply By February 20, 2011
A lot of the food that we eat today contains genetically modified ingredients and usually without our knowledge. The reason that this is done is that it ensures and sustains food security around the world as the population increases. The population now is at 6 billion people and is expected to double in the next 50 years. Genetic engineering is when a scientist manipulates a gene to create plants, animals, and microorganisms unnaturally. These items are created to withstand cold as unexpected frost can destroy many crops a year. Some reasons this is done is to achieve higher yield, improve the nutritional value and improve taste of food. Genetic engineering ...view middle of the document...


There are some dangers that come with genetically engineered foods. Many of the opposed claim it causes nuclear pollution, global warming, and the toxic effects of pesticides and herbicides. Most of these crops developed are resistant to herbicides. Therefore this will result in greater pollution to our food and water with toxic agrochemicals. Many of the opposed also question ethical concerns due to the transferring of animal genes into plant genes. Vegetarians and religious groups would find this process unacceptable.
Foods have been genetically modified for many years. This process is called selective breeding; this was done creating plants in more qualities. 60% of all processed foods contain genetically modified ingredients. There will continue to be a debate on this subject for years to come. I believe that once everyone can understand the process they will be a little more comfortable with the matter. However then there is another issue to bring up, once we have perfected cloning foods, will we start cloning humans? Will this be regulated by the government or will anyone be able to clone anyone?
I just want to leave with a few more of the pros and cons of genetic engineering. Many plants can be altered so that they contain less calories and more fiber or starch. Genetically modified crops can also carry medicines and vaccines to parts of the world where it is too expensive to keep them. There are concerns that insects will become resistant to the natural pesticides in plants.
