World leaders are finally realizing that we're facing a food crisis: they're currently having a meeting in Rome to discuss it, and UN chief Ban Ki-moon recently stated that we need to grow 50% more food by 2030 to satisfy needs (I believe this is a conservative estimate). This is not much of a surprise to me -- I mentioned the upcoming food crisis in my earlier article on biofuels, and it's also related to the energy situation I discussed before that .
