Turning off auto-hyphenation

Hi, My site (Catch Evolution) is automatically hyphenating some words at the end of a line. eg "tech- nology on this page: http://thechurning.net/about-2/meaning-of-the-word-churning/ But this is a waste of time, since it does not produce a justified right margin. (The right margin is just as ragged and varied as it would have been if the word 'technology' had been kept whole). There is no benefit. And the result just looks silly and harder to read. How can I turn OFF auto-hyphenation and keep the words whole? In future, is it possible to have the default as auto-hyphenation OFF, with an option for people who want it to turn it on? Many thanks, Finn Jackson
