genetically modified foods and social concerns
biotechnology is providing us with a wide range of options for how we can use agricultural and commercial forestry lands. the cultivation of genetically modified (gm) crops on millions of hectares of lands and their injection into our food chain is a huge global genetic experiment involving all living beings. considering the fast pace of new advances in production of genetically modified crops,...
متن کاملGenetically Modified Foods: Breeding Uncertainty
Background: Skeletal muscle depletion is an important complication of chronic obstructive pulmonary disease (COPD) but little prospective data exists about the rate at which it occurs and the factors that promote its development. We therefore prospectively investigated the impact of disease severity, exacerbation frequency and treatment with corticosteroids on change in body composition and max...
متن کاملGenetically Modified Foods: Breeding Uncertainty
Genetically modified (GM) crops first appeared commercially in the mid-1990s to what seemed a bright and promising future. Resistant to pests and the herbicides used to control weeds, these new crops were so popular with farmers that millions of acres were planted with them by the turn of the millennium. Today, GM crops are grown commercially by 8.25 million farmers on 200 million acres spread ...
متن کاملLabeling of Genetically Modified Foods
Whether or not to require labeling of food produced from crops that are genetically modified (GM) using recombinant DNA technology is a key issue in the ongoing debate over the risks and benefits of using biotechnology in agriculture. The U.S. government regulates GM food technologies, but once GM crops are approved they are considered to be ‘substantially equivalent’ to their conventional coun...
متن کاملEthics and Genetically Modified Foods
Much of the food consumed in the United States is genetically modified (GM), i.e. derived from microorganisms, plants, or animals that have been manipulated at the molecular level to provide them with traits that farmers or consumers desire. These foods often are produced using techniques in which " foreign " genes are inserted into the microorganisms, plants, or animals. Foreign genes are thos...
