Context: Slater is also a fundraiser and spokesperson for suicide prevention awareness. He has surfed in celebrity events for Surfers Against Suicide, telling sports website 'Athletes Talk': "I've lost a couple of friends myself to suicide and it's just a horrible thing that can be prevented. People get in this dark place and they don't know what to do so it's always nice to see a non-profit that isn't turning into anything else other than just trying to help people."

Slater is passionate about preserving oceans globally and protecting temperate reefs in California through his relationship with Reef Check. Slater is on the Board of Advisors (the Ocean Advocacy Advisory Board) of ocean conservation organization Sea Shepherd Conservation Society.
