YOUR CLAIM: Biofuels are better for the environment than fossil fuels
: Biofuels are those fuels that contain energy and are derived from plants or biomass. They include Ethanol (an alcohol), Biodiesel (an oil) and Biojetfuels. First-generation Ethanol feedstock includes food crops (like corn), crop waste (sugar cane), while second-generation feedstock, which is more sustainable, includes algae and lignocellulosics (woody plants and grasses). Biodiesel feedstock includes vegetable oils and animal fats, and more recently, more sustainable waste fats, oils and greases.
