The Gene Revolution

Advantages

increased exports and rising farm incomes
less fertilisers and pesticides are needed
provides farmers with disease-free planting material
develops crops that resists pests and diseases
some studies suggest yields increase significantly

Disadvantages

seeds only last one growing season
some weeds are now developing herbicide resistance
farmers depend on buying seeds and chemicals from TNCs eg Monsanto
does not always improve food security as many crops are grown for exports
public opinion may reject the technology eg UK
deforestation occurs to increase the area under GM crops eg Latin America
fears for biodiversity by cross contamination

Evaluation

not the best solution for developing countries as it is a revolution more focused on profits that can be made from high yields obtained. Big TNCs may have no regard for the environment as they are driven by increasing their profit margins.
