Entourage star and Lonely Whale Foundation co-founder Adrian Grenier has launched the charity's #StopSucking campaign, encouraging people to stop using plastic straws which pollute the ocean and harm marine life.

Van Jones, Amy Smart, Kendrick Sampson, Emmanuelle Chriqui and Daniel Franzese are among celebrities backing the campaign, and Grenier commented 'By 2050, it is estimated that there will be more plastic in the ocean by weight than fish. Our ocean and marine life are suffocating and the suffering will only get worse if we do not take immediate collective action'.
