and time, and fully appreciate and protect their environment as much as
possible."</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.dailygalaxy.com/my_weblog/2007/12/earths-clock-of.html"><P>In "The Life and Death of Planet Earth," Brownlee and UW
