A love for the ocean goes beyond just enjoying what it has to offer you, but what you can offer it back in return.

This is the reason why volunteer Pete Markel continues to join ODA cleanups—to keep our marine habitat clean from man-made debris.

Caring for animals, caring for the ocean & caring for our community is what ODA strives to do with every cleanup.

Defending our ocean is more than just removing rubbish from our waters, its about being stewards & advocates for our community and ocean that we care about so much.

[Ocean Defenders Alliance @OceanDefenders]

Unpredictable conditions, a committed team & a huge impact for the ocean. That sounds like an ODA cleanup dive to us!
