Genetically Modified Foods
What are Genetically Modified Organisms (GMOs)? Organisms created when scientists move the genes they want from one organism to another.
How is that different from breeding? Breeding Farmers and breeders take traits they like, and try to put them into similar species. Genetic Engineering Scientists take traits they like, and put them into any species they want Only works with similar species. Can work with any species (plants mixed with animals, etc) Much slower process Faster process. Ie: If a breeder wants a smaller dog, he mates two small dogs together. Do that enough, and you get a chihuahua. Ie: If a scientist wants to make wheat resistant to an herbicide, he/she might mix animal DNA into the plant.
What are the benefits? Can raise food that: Is more nutritious (put in nutrients we might otherwise not get, like extra vitamins) Grows faster Is more resistant to diseases or insects Uses less resources (like water) to grow
What are the drawbacks? Some people worry that GMOs might not be safe Using more pesticides might make stronger bugs GMO foods can be owned by corporations who have all the advantages

Who uses GMOs? In 2003, six countries grew 99% of the world’s GMO food. In 2003 55% of the 76, 000 hectares of soybeans planted around the world were transgenic , or genetically modified Between 1996 and 2003, the global area of GMO farms increased from 1. 7 million to 67. 7 million hectares.
