The Beluga whales of the St. Lawrence River
Article Abstract:
The population of Beluga whales in the St. Lawrence River has been severely reduced due to intensive hunting. When hunting diminished, the population did not recover as expected. Research indicates that the whale's blubber concentrates toxic chemicals, thus causing cancer and death among the Belugas.
