Ecological Warning Signs

Uploaded by : Essays-Now.com

A 4 page research paper that discusses the significance of marine mammal deaths. The writer argues that in previous eras, miners would take canaries into the mines with them and use them as living barometers that would tell them when oxygen levels in the mines got too low for safety. It would be thought extremely foolhardy and ludicrous is miners, on seeing the canary die, had shrugged their shoulders and continued working, yet, metaphorically, as a society, we are doing the equivalent. Marine mammals, the "barometers of the sea's health" are dying, giving a dire warning to the human race that our activities are upsetting the delicate ecological balance that makes life on earth possible, yet authorities continue to ignore the implications. The writer discusses the situation and then offers possible solutions. Bibliography lists 1 source.
