Yes, each HUMAN PLAYER can hold and handle one POLLUTANT at a time, resulting in a maximum of three (3) possible POLLUTANTS held by an ALLIANCE’S HUMAN PLAYERS. Therefore, each ALLIANCE can only have three (3) POLLUTANTS out of the OCEAN at a time. Keep in mind that any POLLUTANTS held by HUMAN PLAYERS at the end of the MATCH are considered to be in the OCEAN.
