Research program is launched to produce genetically modified varieties of a food crop. the aim of the program is to create varieties with fruit that ripen quicker. which idea can be used best in an argument against such research?

I think the best argument is that it is better not to tamper with nature in the process of ripening because ripening faster is just to get the fruit to market faster and make more money rather than provide food which is not genetically modified because mixing species is not natural and the effects on humans have not been proven yet of these types of foods.
