Whaling
People have been killing gray whales for hundreds of years.
Different cultures would kill the whales for food and tools.
No part of the whale was wasted. The problems started when people
began killing whales for profit.
Before 1857, there were 15 thousand gray whales in the Pacific
Ocean. Although, the hunting of whales was legal, the killing
of gray whales was not widespread.
Scammon
In 1857, Captain Charles Scammon discovered a lagoon in Baja
California where gray whales went to calve. The shallow water
of the lagoon made the gray whale easy prey for the whalers.
A drastic decline in the gray whale population resulted.
 By
1898, the gray whale population was only 2,000. Fortunately
for the gray whale, the demand for whale oil and bone had also
gone down. The whalers did not hunt the whale as often and the
whale population started to rise.
In 1925, a new boat was invented that made whaling a lot
easier. It was called a factory boat. Look at the year 1946
on the graph.
In the early 1940's, gray whales were close to extinction.
In 1946 the International Whaling Commission was formed. The
IWC had laws passed that prohibited the killing of gray whales
Between 1946 and 1983 the whale population grew by 14,000,
or 500 per year. By 1983, there were 16,000 whales in the
Pacific. By 1992, the population was over 20,000.
The whale population is still growing today. In time, the
population will stop growing. This will happen when the food
supply can not feed any more whales.
