 There is significant research in algaculture methods to make biofuel from algae.Concerns have been expressed about growing crops for fuel use rather than food and the environmental impacts of large-scale agriculture and land clearing required to expand the production of vegetable oil for fuel use.These effects/impacts would need to be specifically researched and evaluated, economically and ecologically, and weighed in balance with the proposed benefits of vegetable oil fuel in relation to the use of other fuel sources.
