The Rainbow Warrior is on tour in the Mediterranean sea to expose plastic pollution. The tour has started on World Oceans Day (8th June 2017) in Valencia, Spain and continued in Italy, Croatia and Greece. A final leg takes the ship into the Bulgarian coast of the Black Sea, a basin also impacted by plastic pollution. During the ship tour, the Rainbow Warrior stops in several ports in each country and the team onboard meet with politicians, hold open boat events for the public, and carry out simple scientific experiments to expose plastic pollution in the Mediterranean Sea. In addition, while at sea the ship conducts scientific research in collaboration with scientific institutions in each country.
