Our Plastic polluted oceans
Posted on September 26, 2012 by DrRossH in Plastic & WildlifeLast night we went to a presentation by Charles Moore, who is credited with discovering the plastic Pacific Garbage Patch. The region NE of Hawaii that has a higher concentration of plastic bits then the rest of the Pacific due to ocean currents leading to this region. Needless to say a very good presentation. His biggest problem item is the very small pellets from either plastic degradation or the raw batch pellets that are in the oceans and killing vast numbers of fish and birds with horrible deaths of
1) starvation, (them feeling full as their stomach is full of plastic but no nutrients and the larger pieces relative to the animal size, cannot pass through their intestines), or
2) suffocation, or
3) drowning as their buoyancy changes with the plastic in them and they can’t dive down, or
4) toxicity of consuming plastic that has accumulated toxins on to its surface as it floats around the ocean regions. While one little plankton may not die of toxin poisoning, it is their predator that eats 1000,000’s of them that has high toxin content and then that one’s predator who eats many of those ones and on up the food chain it goes to get to the top food eater, us.
On a scale of planet issues, he agrees with PWS, this plastic waste issue is more important than Climate Change as Climate Change is not killing off all this wildlife at the moment and the consequences are going to be with us just as long lasting.
