Essay / Research Paper Abstract
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.

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 seas 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. Over the last quarter century, government statistics show a consist increase in the number
of marine mammals stranded on beaches, as well as increased die-offs of whales, dolphins, sea lions, and other mammals on the U.S. coasts (Weiss A.1). Just in the last decade,
14,000 seals, sea lions and dolphins and 650 gray whales, have been found sick and/or dead along the California shore (Weiss A.1). Experts, such as wildlife pathologist Greg Bossart, believe
that these deaths are mainly due to a "pandemic" of toxic algae and bacteria in the ocean food chain (Weiss A.1). These elements have also been implicated in the increase
of tumor growth and increasingly compromised immune systems, which leaves the animals "vulnerable to parasites, viruses or bacteria" (Weiss A.1). Normally, the microscopic population of the ocean is held
in check, but toxic algae thrives on "nitrogen, phosphorus, and iron," which enters the ocean by the ton each year from "partially treated human waste" (Weiss A.1). Sewage treatment plants
cut down on the amount of disease-causing bacteria but do little to affect the elements that naturally feed algae blooms. Also, the destruction of wetlands, which provide a natural filter
for nitrogen have played a role in this cycle, as well as over-fishing algae-eating fish (Weiss A.1). Furthermore, climate change and warmer waters also serve to seed up microbial growth
