Evaluate the impact of issues raised in the article.http://www.abc.net.au/science/articles/2011/04/18/3192585.htm?topic=

The article is fairly persuasive in its idea that warming
of the Earth's waters could hold profound impacts on fish and other marine organisms. 
The global interdependence of any change in an ecosystem holding connection to other
elements within it is demonstrated.  The article's impact is to speak to a potential
danger of global warming.  If the Earth's temperature increases even in the slightest,
this disrupts the ecological balance of the fish and they will either migrate beyond
their comfort zone, stop growing, or even die out entirely.  The article's suggestion
that cooler waters helped the fish live is a relevant evidential claim that supports the
idea that global warming can carry profound impacts that might not have been fully
grasped.  In the end, the article's impact is that it proves supportive of the side in
the global warming debate that argues the validity of the
problem.
