GENETICALLY MODIFIED FOODS

Pest resistance Crop losses from insect pests can be staggering, resulting in devastating financial loss for farmers and starvation in developing countries.

Farmers typically use many tons of chemical pesticides annually. Consumers do not wish to eat food that has been treated with pesticides because of potential health hazards, and run-off of agricultural wastes from excessive use of pesticides and

fertilizers can poison the water supply and cause harm to the environment. Growing GM foods such as corn can help eliminate the application of chemical

pesticides and reduce the cost of bringing a crop to market

Cold tolerance Unexpected frost can destroy sensitive seedlings. An antifreeze gene from cold water fish has been introduced into plants such as tobacco and

potato. With this antifreeze gene, these plants are able to tolerate cold temperatures that normally would kill unmodified seedlings.

Disease resistance There are many viruses, fungi and bacteria that cause plant diseases. Plant biologists are working to create plants with genetically-engineered

resistance to these diseases

Drought tolerance/salinity tolerance As the world population grows and more land is utilized for housing instead of food production, farmers will need to grow crops

in locations previously unsuited for plant cultivation. Creating plants that can withstand long periods of drought or high salt content in soil and groundwater will

help people to grow crops in formerly inhospitable places

It might affect the world.

It might have side affects of some GM crops.

We can also become crops and animals start eating us.

If we GM animals we can finish a lot of diseases like :Malaria and etc.

It can have a lot of side affects ad might destory our habitats.

DISADVANTAGES

Page 4: Genetically Modified Foods

For Americans, corn is a crop that's fed to livestock, fermented into motor fuel or turned into a cheap sweetener. To millions of Africans, corn, or

maize as they know it, is a staple food for people of all economic classes. But African farmers already struggle to grow sufficient maize, which is a thirsty, fertilizer-hungry crop. What will happen as the climate changes and the population grows? Kenya alone is expected to need nearly three

times as much maize to feed its population in 2050 as it does today.

Successive U.S. administrations have joined American agribusiness interests in arguing that Africans must drop their opposition to

genetically modified crops if the continent is going to feed its growing population.

The Bill and Melinda Gates Foundation is funding research that is using technology from biotech giant Monsanto Co. to engineer maize that's

much more resistant to drought than conventional varieties. Bill Gates says these new seeds will be vital to boosting African food production.

But the crop also would serve the U.S. industry's geopolitical interests: It will be tougher for Europeans to continue resisting biotech food if there

is a new GM crop that could be vital to the survival of poor Africans.

PUBLIC OPINION

Page 5: Genetically Modified Foods

I disagree because it can effect us in our bodies and if ladies have a baby in them it

would be sad if the babies become a crop and the

animals will eat them. So that’s the reason I disagree.
