Jessica Biel, Emile Hirsch & team reaching Kilimanjaro's top

"Reaching the top of 19,340-foot Mt. Kilimanjaro proved to be an emotional experience for Jessica Biel and Emile Hirsch, who climbed
 Africa's tallest peak to raise awareness of the global water crisis.
Jessica Biel and Isabel Lucas attending "Summit on the Summit: Kilimanjaro Pre-Ascent Event" held at Voyeur on December 9, 2009 in West Hollywood, California.

"I
 walked over to Jessie and gave her a big hug," UN Foundation executive
 Elizabeth Gore, who also made the hike, tells PEOPLE via satellite phone. "The two of us embraced and
 we just cried. Every single one of us was in absolute tears.""The temperature was zero degrees and so many people were struggling," adds 
she. "People had hurt limbs, people had altitude sickness."

environmentalist Kick Kennedy, granddaughter of Robert F. Kennedy – reached
 the summit, they quickly had to begin their descent". Source: www.people.com
