Taking their responsibility as the global governing body for underwater sports seriously, CMAS supported two events at the Lebanon Water Festival and in the Seychelles on "World Clean-Up Day". 

The Lebanon Water Festival brought together CMAS and Operation Big Blue Lebanon to promote the coastal clean-up event to help combat sea pollution.

A social media campaign encouraged local residents to join the cleaning efforts.

Scuba diving centres all up the coast also helped with clean up activities on the beaches and under the water.

The Scuba Divers Federation of Seychelles (SDFS) was also part of the environmental action.

As a member of CMAS, the SDFS arranged clean-up activities in three places - La Digue, Praslin and Mahé.

SDFS President Manuela Alcaniz claimed that she fully supported the efforts of members in the run-up to the World Clean-Up Day in an open letter.

He also reealed that children and young people had been encouraged to join in as the future protectors of the oceans.

CMAS was founded in 1959 and now oversees 130 National Federations from five continents.

It is responsible for organising international underwater sport events but also conducts research on the marine environment to educate people.
