The Clean Up the World Campaign kicked off with a parade on Saturday, supported by local schoolchildren.
The Environmental Safety Group which organised the event, strives for a cleaner environment taking the message to the street in its aim to tackle the issues.
Environment Minister John Cortes, who took part in the parade, told the youngsters they were the present and the future and the ones who can really make a difference. He told them this was their planet, and their responsibility, as the older generation had let it down.
Students helped to clean up various areas around Gibraltar, in the hope that they will be included in the Governments new cleaning contracts.
400 volunteers were involved in cleaning 25 sites around Gibraltar, including coastal areas
