Disadvantages & Advantages of Genetically modified food crops
High-Yielding Variety (HYV) crops
Advantages
Shorter growing season
Resistant to pests and diseases
Suitable for mechanical crop care and processing
Disadvantages
Lacks an important plant defense mechanism against predatory animals or fungi and as a result are more prone to pests and diseases
Absence of genetic variation causes pests and plant diseases to spread quickly and easily
Genetically modified food (GM) crops
Advantages
Shorter growing season
Resistant to pests and diseases
Resistant to extreme weather
conditions
More nourishing to the body
Certain crops have been developed
to have higher nutritional value. E.g. Golden
Rice has been developed to have higher values of Vitamin A which can prevent
blindness in LDCs
Increased income for farmers
Decreased Environmental Pollution
Genetically modified crops reduce dependency on chemical
fertilizers and pesticides, which may potentially pollute
the environment
Disadvantages
Dangerous to some insects. This is because the new genes of the crops can be deadly to certain insects like butterflies that are not actually dangerous to crops.
Do not taste as good as naturally produced crops.
Dominance of agribusinesses
Genetically modified crops are expensive as a
lot of research and time have been put into them.
Hence, they require high capital investment,which is only affordable to big companies and DC s. Small scale farmers and LDC s cannot afford the seeds due to the high price. This will widen gap between wealthy and poor farmers.
Potential health risks
Growing concern that incorporating foreign genes
into plants may have adverse effect on human
health,such as allergic reactions.
