     The BRICK Awards are given each year to young people who make our world a better place. These youth

service awards were presented recently to twelve young people for their community action projects.

     For the first time, the BRICK Awards were presented on an American TV show. Twelve people under the

age of 25 from the United States and Canada won awards of 10,000 dollars to continue their work.

     They were honored for their protection in four areas: public health, community building, education and

environment. Young people voted online for the top four winners. These people received Golden BRICK Awards,

worth a total of 25,000 dollars.

     One of these winners is Jennifer Staple of Newton, Connecticut. She created an organization called Unite

for Sight. It provides eye care and education programs to more than 400,000 people around the world.

     Kimmie Weeks is another Golden BRICK Awards winner. He survived the war in Liberia and later got

political protection in the United States. Now he lives in Newark, Delaware. He started Youth Action

International, a group that helps children affected by war. It operates programs in several African nations.

     Ashley Rhodes-Courter lived in 14 different homes before being adopted at the age of twelve. Now she lives

in Crystal River, Florida. She works to improve the lives of children with no parents.

     Divine Bradley is the fourth Golden BRICK award winner. He lives in Brooklyn, New York. As a teenager,

community led by young people. It has provided after-school programs to more than 500 young people.
