Issues relating to biofuels

Should we still be concerned about the Fukushima Nuclear Power Plant in Japan that is still dumping nuclear waste into the Pacific Ocean?

One of the major concerns surround biofuels is the amount of land that is required to grow enough biomass to meet current energy demands. The quantity of land required is so great that we cannot simultaneously meet our energy needs and grow enough food as well. The solutions, as we will see, range from producing more energy dense food, to growing plants that don't utilize the same resources as food crops, to using only left over biomass as feedstock.
