Jessica Biel starts Kilimanjaro climb

Jessica Biel and Emile Hirsch have embarked on their trek up Mount Kilimanjaro.

The two, along with Lupe Fiasco, Elizabeth Gore and Isabel Lucas, are currently climbing Africa's tallest peak to raise awareness and funds for the global water crisis, reports People.

Before the climb, the group spent time with villagers near Arusha, Tanzania to get a firsthand look at the crisis, which has left one billion people around the world with no access to clean water.

"Meeting the people and community in Tanzania… has been an invaluable and eye-opening experience for me," Biel said.

She added: "My hope is that others will be inspired to find ways that they can help."

The climbers also hope to provide funds for clean water solutions and programmes around the world.
