Gene Technology • Selective Breeding • Genetic Engineering • Genetically Modified Foods(Frankenfoods) DONE
Selective Breeding • Since 18th century, knowledge about genes has been used to improve plants and animals. • Farmers and scientistsselectthebestpossible specimensto breed from. BACK
Genetic Engineering基因工程 1/2 • Genetic engineeringrefers to“cutting and pasting”of genetic material. • Genes can be removed, added or replaced to producedesirablecharacteristics.
Genetic Engineering基因工程 2/2 • “Genetic engineering” has been done on plants, with the main focus on improving crop production and quality. • Genetic engineering can produce new and better plants and animals. BACK
Genetically Modified Foods • Generally speaking, the phrase ‘genetically modified food’ can be used to refer to any product that gets some of its content from an organism that has been genetically modified.
What are the benefits of GM foods? • increased yields from agriculture • more powerful control of pests and weeds • reduced use of some agrochemicals • enhancement of nutritional value or other characteristics of crops • and more!
What are the dangersof GM foods? • risk of transferring crop traits to wild species • negative impacts on wildlife from more powerful control of pests and weeds • increased use of some agrochemicals • increased corporate control of seed supply • and other effects!
What are your opinions? • Write a short paragraph on GMF. Take a stand and give enough supporting ideas to express your opinions. BACK
