Water hungry biofuels pose problems

Time to rethink biofuels

At a conference on Tuesday, "Environmental expert Tim Barnett of the Scripps Institution of Oceanography cautioned that water shortages also would be a pressing issue for many regions." Thus, according to the DetroitNews, "Climate and energy experts said the production of some forms of energy -- biofuels, for instance -- required large amounts of water," should therefore be reevaluated.

Thus, focus should be placed on biofuels, such as algae, that require little water and little land.

Isn't it time to get smart about biofuels?
