GM Crops
Advantages
-
-
-
Crops can be altered for a longer shelf life, less food is wasted
Crops can be ripened earlier than normal so fresh foods can be available for consumers earlier in the year
Crops can be modified with extra nutrients which can improve nutrition in poor countries e.g. golden rice has been genetically modified to contain carotene ( vit. A )
What it is
A genetically modified food is one that's had its genes altered to give it useful characteristics, such as improving growth or changing its colour:
. GM plants are produced by inserting a desirable gene from another plant, animal or a bacterium into the plant you want to improve
. Plant modified seeds and then grows the GM crop
GM maize- pest-resistant. The farmer gets a bigger yield of maize because less crop is eaten or damaged by pests.
-
Currently, no GM crops are grown in the UK, but it is popular in other countries e.g. USA, grows lots of GM maize, cotton and soya beans
Disadvantages
-
Concerns modified genes could get into wider environment and cause problems e.g. weedkiller resistance gene could be transferred to a weed making it an indestructible " super weed "
