Findings related to marine debris
Studies of marine debris found the biggest threats were
plastic (not metal or wood)
- bits of debris that were 34. (harmful to animals)
- There was little research into 35. e.g. from synthetic fibres.
Drawbacks of the studies examined
- most of them focused on individual animals, not entire 36.
- the 37. of plastic used in the lab did not always reflect those in the ocean
there was insufficient information on
- numbers of animals which could be affected
- the impact of a reduction in numbers on the 38. of that species
- the impact on the ecosystem
Rochman says more information is needed on the possible impact of
- future 39. (e.g. involving oil).
