Talking Trash

The Problem With Marine Debris

slide2

Marine Debris: What is it?

Any unnatural items that makes it

way into our ocean or marine environment

Directly (i.e. dumping)

Indirectly (i.e. street litter washing out to sea

slide3

30-40% of debris originates from

ships at sea

Estimated that 5 million items of marine litter are thrown overboard or lost from ships everyday

Over 46,000 pieces of plastic litter are believed to be floating on every square mile of ocean

slide4

Derelict Fishing Gear

Glass, Metal, Styrofoam, and Rubber

Derelict Vessels

Types of Marine Debris

Plastics

TYPES

slide8

Wildlife Entanglement

Entanglement/Injury

Ingestion/Starvation

Both can lead to death

slide10

Destruction of Marine Habitat

Breakage and smothering of coral reefs

Divers can remove nets…

but the reef is already damaged…

slide11

Transportation of Non-Indigenous Species

Diadumene lineata: an invasive intertidal anemone

slide12

Navigational Hazards that may cause Vessel Damage

Large accumulations of derelict fishing gear can:

Damage a vessel

Entangle the propellor

Result in a navigational hazard

Result in a safety risk for those onboard

slide13

Trawler tangles with

derelict net

propellor snare

slide14

Marine Debris Can be Toxic

Persistent organic pollutants (POPs): a class of chemicals that can be released by ordinary garbage

Extremely toxic, even at low concentrations

Accumulate in the fatty tissues of marine mammals

POPs have been shown to disrupt hormones that could result in cancer and birth defects

slide16

NOAA\'s Marine Debris Program

MISSION

A national effort to

prevent,

identify,

remove,

reduce

marine debris

slide17

Also

protect and conserve

our nation’s natural resources and coastal waterways from the impact of marine debris

Promotes: research, monitoring,

outreach, and reduction outcomes

slide18

NOAA’s marine debris program

2006: first ever comprehensive project to survey and remove marine debris in the main Hawaiian Islands.

Aerial surveys of all main islands

slide19

ID’ed over 700 debris sites and approx. 129 tons of debris

Waiohinu-ka Lae Coastline, Big Island

Kanapou Bay, Kaho’olawe

42 tons in 9 miles

5 tons in ¼ mile

slide21

How you can help

Get involved in local clean-ups

Don’t litter; find a trash can

Leave your favorite places cleaner than when you got there; bring a trash bag with you when you go to the beach

Reduce the amount of waste you produce and recycle when you can

slide22

Learn about the issue and help spread the word!
