Some people think that genetically modified (GM) crops are a positive development. Others, however, argue that they are potentially dangerous. Discuss both these views and give your own opinion.

method of production argue that food production can be massively increased by making crops more resistant to pests.

Secondly

, they believe that food can be improved by adding vitamins or removing problem genes that lead to allergies,

for example

in peanuts. Fruit and vegetables can

much longer if the gene that ripens them is modified.

This

means that they can be stored for much longer periods and so there will be less waste.

However

. people who oppose the widespread use of

GM

techniques worry that there could be long-term negative effects. They are concerned that so far the

GM

industry has not been able to prove that they are safe. The issue is not only how safe

such

foods are for humans, but

also

what long-term effects they may have on the environment and wildlife populations.

For instance

, there is some evidence to suggest that

GM

crops may contaminate nearby plants. In conclusion, I tend to agree with these concerns. I think that while there may be obvious benefits to

GM

crops, overall, they present more potential dangers. Their impact could be so large and so irreversible that more long-term studies should be carried out before their use spreads any
