Transcript of Genetically Modified Food

Genetically Modified (GM) Food Genetically modified foods (GM foods, or biotech foods) are foods derived from genetically modified organisms (GMOs), such as genetically modified crops or genetically modified fish. What is GM Food ? The enhancement of desired traits has traditionally been undertaken through breeding, but conventional plant breeding methods can be very time consuming and are often not very accurate. Genetic engineering, on the other hand, can create plants with the exact desired trait very rapidly and with great accuracy. Why GM Food ? increase income for farmers
increase food supply
improving nutritional needs
reduces environmental
problem Why YES to GM Food ? The farmers are able to enjoy an increase in their output and income.
EXAMPLE:
Scientist found out that arctic flounder fish could withstand cold temperatures. Therefore, they put the DNA of the arctic flounder fish into the tomatoes to allow the tomatoes to withstand cold temperatures.
Because the GM tomatoes can remain fresh longer they can be allowed to ripen in the sun before picking - resulting in a better tasting tomato.GM tomatoes can tolerate a lengthier transport time. This means that market gardens can avoid picking tomatoes while they are green in order that they will tolerate the transport.The producers also have the advantage that all the tomatoes can be harvested simultaneously. http://www.csa.com/discoveryguides/gmfood/overview.php

THANK YOU CREDITS 1. Increase income for farmers GM Food are able to increase food supply because it is able to produce a higher output than non GM Food.
EXAMPLE:
Super rice is able to double the output of normal rice which results in an increase in food supply. This is an advantage to the LDCs because food prices will decline causing it o be more affordable. Therefore it helps to reduce problems of malnutrition and improve people's health. 2. Increase food supply Some food crops have been genetically modified to have a higher nutritional level.
EXAMPLE:
Golden rice have been enriched with beta -carotene to supplement the lack of vitamin A in rice diets in LDCs. The introduction of Golden rice helps to reduce th enumber of people and children dying or going blind in LDCs due to the lack of Vitamin A. 3. Improving nutritonal values of food With GM Food there is no need to use chemicals in agricultural because they rely less on chemicals such as the need to us pesticides. 4. Reduces environmental problems Potential health risk
Loss of biodiversity
Loss of natural species Why NO to GM Food ? Many people fear the potential health risks that might be associated with eating GM Food because some GM Food may contain certain food substance that they might be allergic to.
EXAMPLE:
Allergic to Lectins whic is a protein found in beans. But now, Lectin is used n potatoes to prevent aphids from attacking potato plants. therefore now people who arer allergic to Lectin will be scared to eat potatoes. 1. Potential health risk Biodiversity refers to the great variety of living things in an ecosystem. So some pests resistant plants are indirectly destroyinh harmless insects like the Monarch Butterfly.
EXAMPLE:
Larvae of the Monarch Butterfly that feeds on the plants that were dusted with BT corn pollen will have the larvae grown slowly and die at a higher rate. So when it affects the foodchain, the species will become extinct and therefore resulting in the loss of biodiversity. 2. Loss of biodiversity Some GM Food crops may also be genetically polute natural crops that are not genetically modified
EXAMPLE:
When the pollen of a pests-resistant crops is carried by the wind or insect to compatible natural crops, the offspring of the organic crops will also become pest resistant. 3. Loss of natural species This is due to the reason that thus far, the purpose of genetic modification has been for crops to be pest- and insect-resistant and survive harsh conditions such as drought or flood. So farmers in Singapore do not need to worry about their crops since the crops are able to withstand any weather. Furthermore, GM Food improves the nutritional value of the food for example Golden Rice. Therefore this is an advantage since Singaporeans do noot need to pay soo much for healthcare. Hence, Singapore supports GM Food due to the positive impacts of GM Food. Although GM Food is not highly supported in many countries, Singapore in one example of a country that supports GM Food. Therefore my stand to GENETICALLY MODIFIED FOOD is that ... This is due to several reasons ...

1. Since there are more positive effects than negative effects, i believe GM Food is helpful as many people can benefit from it.

2. Since GM Food can improve nutritional value of food and pesticides are not used in GM Food this benefits people as we can spend lesser on healthcare instead.

3. Farmers also benefit from GM Food as their income is increased and they can spend lesser on pesticides.

I SUPPORT THAT GM FOOD IS HELPFUL
