以下の英文の日本語訳で困っています。誰か教えてください。
(1)Of the 12 men who have walked on the moon, Harrison Schmitt, is the only one with scientific training in geology.
(2)Schmitt's work on the Moon in 1972 ranks as one of the most exciting and productive episodes in the history of exploration.
(3)His new book, Return to the Moon, is structured as a legal document, in which Schmitt argues for returning to the moon to mine the isotope helium-3.
(4)He claims that because fossil fuels are limited in supply and because their extraction and use harm the environment, our world requires new sources of energy.
(5)The ultimate solution, he suggests, is the generation of power by nuclear fusion－not of deuterium and tritium, as is usually proposed, but of deuterium and helium-3.
