Conservation Issues Facing Whales and Other Marine Mammals

Whales are marvelous creatures. The blue whale is the
largest creature that has ever lived on this planet, reaching length up to 30
meters and weighing more than 190 tons. They have been roaming the seas since more
than 25 million years ago and have their roots as far as 200 million years ago,
when it is believed the first mammals developed. As all mammals descend from
land, it is astounding how whales are totally adapted to the sea today and they
are unable to survive on land. Being that they are special creatures in many
ways, it is somber the fact that they have been threatened with extinction by
number of reasons, while some species have made the near extinction list.

 The main reason
whales are facing extinction is humankind. Every year around whales are being
killed by whalers.  The way people
endanger whales is threefold: directly by whale hunting and indirectly by
fishing and polluting their natural habitat, the seas and oceans. Even though
commercial hunting has been limited since 1982, when the International Whaling
Commission set a limit to the whale killing number per annum, there are still many
illegal endeavors, being disguised as hunting for scientific reasons, when it
is purely for commercial reasons and making profits. Whaling has been part of
some nations’ culture for centuries. For example, the people from Faroe Islands
consider whaling to be part of their heritage and they have a ritual each year
which involves killing around 250 whales, creating a bloody sea. And as
technology has developed over the years, along with increased commercial demand
for the use of whale, for food, oil and even clothing, it is becoming a lot
easier and more appealing to capture these creatures, hence increasing their
mortality rate. An indirect way humans are involved in whales’ deaths is
fishing. Beaked whales and other marine mammals are unintentionally caught in
fishing nets, mostly in gillnetting and seine netting, significantly causing the
increase of their mortality. Another indirect cause is marine pollution. As each
year the seas become more and more polluted, whales, as other marine animals
are affected, developing cancers, mothers passing toxins when breastfeeding
their young or be poisoned by swallowing waste, such as plastic. An unpopular
reason whales die is stranding of pods near shore. It is not uncommon for
whales to be stranded in large groups, sometimes over 100 whales at a time. It
is not yet known why and how this happens, but some researchers think this
might be and attempt of the pod to help a whale, and strand themselves in the

The most endangered species are the Bowhead whales, caused
by their constant hunting in the past 400 years. Before the IWC hunting ban,
they were reduced to 8% of their original population. Gray whales are another
species on the endangered list. As they possess the thickest blabber of any
whale, used to produce whale oil, they are most attractive for whalers. Right
whales were also massively hunted during the 18th and 19th
centuries. Their name even derives from whalers calling them the ‘right’ whales
to hunt, as they very conveniently swam close to shore and floated on the
surface after being killed, making them an easy prey to be transported. Sei
whales were not very interesting for whalers in the past, but as other species
became less abundant, these whales have now made the endangered list. Toothed
whales are also on the list. The white beluga, known as the canary of the sea
for their vocal capabilities, has a subspecies located near Alaska which is
down to 280 whales. Narwhals are very interesting looking whales making them
appealing for hunters. They are mainly killed for their ivory tusks which go on
the market for thousands of dollars. Sperm whales, although the most abundant
species of the large whales, have been part of massive killings in the last two
centuries, when whalers have killed over one million whales of this kind.

As for other endangered species, there are many
organizations that try to preserve these magnificent sea creatures, but their
success is dependent on preventing illegal whaling and stopping marine pollution,
two of the biggest reasons that can cause the extinction of whales.
