Whales play a critical role in
maintaining the fish population
and reducing climate change.
Their iron rich droppings
encourage the growth of
microscopic plants called
phyloplankton that serve as food
for fish and absorb carbon
dioxide from the atmosphere.
Hunting these rare whales has been banned since 1935,
when their numbers had fallen to only about 100. Since then,
their population has not increased as much as expected and
remains below 500. Difficulty in repopulating is largely due
to their habitat. Living within 50 miles of shore, a significant
number die from being hit by ships or becoming entangled or
cut by commercial fishing lines. Pollution, which researchers
suspect suppresses their reproduction, may also play a role.
Ongoing research and conservation projects are seeking to
help the right whale population increase. Scientists monitor
distribution and movement using aerial surveys and radio
devices attached to the whales’ backs. Information obtained
helps in operating conservation initiatives such as early
warning systems to help vessels avoid whales and assistance
to those entangled in fishing lines. Hopefully, these and other
efforts will help provide the right environment for these rare
whales to thrive and multiply. NK
