As startling as the information about land use and total water needs is for biofuels, is it unreasonable? For Example, how do these numbers compare with land and water currently used in agriculture? We clearly need an alternative to fossil fuels, and biofuels have recieved a good bit of attention.
Consider biofuels. Surf the web and indentify potential sources of biofuels. Indentify the biofuel source, briefly describe by the biofuel source is promising, briefly discuss how it will be used as a biofuel. Discuss advantages, and disadvantages. Discuss processes and/or other information you have found. Provide complete references for all your sources of information in MLA format.
