OVERVIEW
1. The ISSUE: Entanglement in marine debris
2. The Impact of Entanglements
3. What WE are doing to reduce entanglements…
4. How YOU can help!

Where does marine debris come from?
Land-based
• 49% of debris on
U.S. beaches is
from land-based
sources*
*National Marine Debris
monitoring Program
Ocean-based
• Gear lost at sea,
lost overboard, or
deliberately
dumped at sea
OBJECTIVES
• Determine sources of marine debris entangling or
ingested by pinnipeds
• Find solutions to reduce entanglements and ingestion
• Find new methods to safely disentangle pinnipeds

Two main types of “entanglements”
1. Neck Entanglements
2. Ingestion of Fishing Gear

Why not just removed entanglements?
• It is often difficult or
impossible to safely capture a
wild sea lion to remove
entangling debris
• We are working on possible
disentanglement solutions, but
we need to continue to focus
on… PREVENTION!

1. Reuse items whenever possible
2. Choose reusable items over disposable items
3. Bring your bags – just say no to single use bags!
4. Recycle as much as possible
1. REDUCE – 2. REUSE – 3. RECYCLE
SUPPORT CRADLE TO CRADLE MANUFACTURING
• Closed manufacturing cycle
• No waste products - products can either be reused and
returned to the cycle, or organically broken down for use
as food for the natural environment
