Who thinks global warming isn't real......??????.....anybody?????.....It would seem that Mother Nature is showing everybody that it's a real thing....there have been massive die-offs in bodies of water around the globe in the past month and change that are documented in this article....as conscientious ponders, we are quite aware of what our fish need to survive...aeration, circulation, water changes, etc...Mother Nature is showing us what she needs here...I think that there are way too many fish in our estuaries and ponds and lakes, etc. A prime example of this is the massive explosion of Asian flying carp in our lakes and rivers...they are taking over a lot of the places making it where other fish cannot thrive...we know that our koi carp can have, literally, millions of babies in their lifetime and the ecosystems are not able to handle the fish load in the wild....with global warming, many bodies of water are shrinking and that equates to less gallons per fish than is acceptable...hence...die offs...with global warming, many bodies of water are heating up and causing eruptions in the substrate of the bottoms of the lakes, ponds, etc and we are getting what i call 'sulfur burps'....who thinks fish survive well in burpy, fart smelling water...???...NOT ME....we, as a whole,people are ignorant to the effects of toxic runoff, pollution and complacency in water management and it is rearing it's ugly head in rather quick fashion....do your part for conservation, no matter how small it may be, and let's see if we can't make our world and our waters a better place to live for us and our piscine friends....now that I have spoken my mind about rivers and enclosed systems....what about the oceans...that is a whole different ball of wax....there should never be the problem of not enough gallons per fish but...when it is polluted by chemical waste, oil leaks, and human waste, etc....the blame falls directly on us.....Billy http://www.mediacoop.ca/story/why-ar...death-ev/18569
