food of the future

i came across this article in the age today. apparently, genetically modifying the tomato may be the key to "boost[ing] crop yields in a move [scientists] say could help feed and clothe millions of people in a time of climate crisis"
really? the tomato is the answer?
i'm really not sure how the tomato is going to clothe people 8)
i would have thought the answer to sustaining a growing world population would be more along the lines of growing/eating foods that work well in local climates and eating less resource intensive foods like meat.
