12 Corn, sugarcane, and kenaf are the plants most often used to 13 produce alternative fuels because they grow so much in a single 14 season that they produce a great deal of biomass to be refined 15 and processed into methane, methanol, or ethanol. But, they are 16 still more expensive than petroleum-based fuels. Industrial hemp 17 is the world's champion photosynthesizer. It could compete 21 economically with petroleum-based fuels. Biomass fuels release 2 fewer pollutants, and the fuel source spends the growing season 3 removing carbon dioxide from the atmosphere through 4 photosynthesis.
Biomass fuels contain no sulphur.
10 Industrial hemp is capable of growing in all climatic zones 11 in America, including Hawaii. It would not compete with food 12 crops for the most productive farm land, and it could be grown in 13 rotation with food crops or on marginal farm land where food crop 14 production is not profitable. Polyester and other synthetics are based 3 on petroleum, the drilling, shipping, refining, processing of 4 which have resulted in contaminated underground sources of 5 drinking water, the contamination of nearshore fisheries, air 6 pollution, and occupational exposure to carcinogens. They form other compounds that 16 help organ muscles to contract, regulate stomach acid, lower 17 blood pressure, and regulate temperature. They also aid in fat 18 transport and metabolism.
