Study shows 90% of seabirds have plastic in their guts.

A new international study estimates 90 percent of the world's seabirds have pieces of plastic in their stomachs. The Tasmania based Commonwealth Scientific and Industrial Research Organisation, CSIRO, has been studying birds and marine debris for several decades and has used computer modelling to look at how badly seabirds are being affected as more and more plastic goes into the ocean. Dr Denise Hardesty is one of the lead researchers.
