5 FOOD & NUTRITION
GROWN FOOD - GM CROPS
| Question | Answer |
|---|---|
| What are people concerned about as regard the production of food? | People today are very concerned about how their food is produced and what effect it has on the environment. Organic foods are very popular, while lots of people are wary of GM foods. |
| What are genetically modified foods? | Genetically modified foods have altered genes.A genetically modified (GM) food is one that's had its genes altered to give it useful characteristics, such as improving its growth or changing its colour. |
| What are GM plants? | GM plants are produced by inserting a desirable gene from another plant, an animal or a bacterium into the plant you want to improve. You plant modified seeds and up comes your GM crop. |
| Why might a farmer get a bigger yield of GM maize/. | For example, you can get GM maize that's pest-resistant. The farmer gets a bigger yield of maize because less of the crop is eaten or damaged by pests. |
| What can GM weedkiller-resistant crops withstand? | GM weedkiller-resistant crops can withstand chemicals that kill the weeds around the crop. |
| Are GM crops grown in the UK? | Currently, no GM crops are grown in the UK, but it's popular in other countries, e.g. the USA grows lots of GM maize, cotton and soya beans. |
| What are 2 advantages of GM Foods? | 1) Crops can be made to grow quicker. 2) Producers can get higher yields of crops for the same amount of seed and fertiliser. |
| What are 2 more advantages of GM Foods? | 3) This makes food cheaper to produce so it's also cheaper for the consumer to buy. 4) Crops can be altered to have a longer shelf life -so less food is wasted. |
| What is 1 more advantage of GM Foods? | 5) Crops can be made to ripen earlier than normal, so fresh foods can be available for consumers earlier in the year. |
| What is 1 more advantage of GM Foods? | 6) Crops can be modified to contain extra nutrients which can improve nutrition in poor countries. E.g. golden rice has been genetically modified to contain carotene (which provides vitamin A). |
| What is a disadvantage of GM Foods? | 1) GM foods haven't been around for long - so their long-term health effects aren't known. |
| What is another disadvantage of GM Foods? | 2) There are concerns that modified genes could get out into the wider environment and cause problems, e.g. the weedkiller-resistance gene could be transferred to a weed, making it an indestructible 'superweed'. |
| What is another disadvantage of GM Foods? | 3) GM producers can't sell their food everywhere-the European Union (EU) restricts the import of some GM foods. |
| Why do some people believe that we shouldn't mess about with genes? | Some people believe that we shouldn't mess about with genes because it's not natural. |
| What are the requirements in the European Union with GM foods? | In the European Union: All GM foods must undergo strict safety assessments and can only be sold if no health risks have been identified. All foods that are GM or contain more than 1% GM ingredients must be clearly labelled. |
| What about meat and dairy products? | However, meat and dairy products from animals fed on GM feed are not labelled. |
