good topic, and not at all far-fetched
well they are trying to clone plants that have been genetically engineered (i.e. one that grows to a certain height or makes its own pesticide), or clone animals that have been altered to produce chemicals (i.e. factor 8 for haemophiliacs in sheep milk). all of these are researc things but they have done it with other plants (corn, coffee, wheat)
cloning would only really be more efficientfor food production if it were to produce animals or plants that had an advantage over other 'normal' produce (i.e. that results in more meat for $ or more bang for your buck)
so cloning a super calorie dense maize might be good, or a wheat which kills pests automatically etc, something hat will give it n advantage.
cloning a standard plant/animal is not that great as while u are assured healthy characteristics (as opposed to a random crop where a certain % will be mutations, short plants, thin anuimals etc) the crop will be more prone to something wiping it all out, and that it costs a lot more than say just letting the animals do it adam and eve style
but yes, i do think cloning these 'super plants' would help 3rd world countries immensly. scientists from these countries are therefore VERY pissed at the publi and media reactiopn over here to GM crops as its potentially lifesaving for them and us to be able to manipulate plants in a changin climate (if the cliamate changes, a lot of our plants wouldnt be able to survive). the media has no solid scientific reason to stand on yet it whipped a frenzy over this
gotta love the media.
