Transcript of Saving Endangered Species (Narwhals)

Threats There are multiple threats to
Narwhals. They are prey to polar
bears and orca. They are even hunted
by Native Inuit people. Facts Narwhals eat squid fish and shrimp.
There are only about 45k-50k individual narwhals.
The reason their population is so small is because the females only give birth to 1 calf every 3 years and take care of them for 1 year. Narwhals "Unicorns of the Ocean" Captive Breeding If zoos used captive breeding for Narwhals then their population would definitely rise. We would also have to teach them how reproduce faster because that is a huge factor in why they're near extinction. They would learn how to adapt better to the climate changes in their habitat.
Captive Breeding (continued) Since Narwhals are really rare
taking them captive will also
protect them from the hunters
and other animals that prey on
them. Citations http://www.kidsplanet.org/factsheets/map.html Captive Breeding Saving Endangered Species There are also other things like climate
change and pollution. This destroys their
habitat, which makes it difficult for them
to survive. "One recent study concluded that the narwhal might be even more sensitive to the impacts of climate change than the polar bear." This shows the climate changes are very impactful for their habitat. This the best decision for them
so that they survive. If they were
just cloned they would still have
trouble adapting to the threats
their habitat has. Continuing
with same weakness would just
lead to failure, again. "We are part of an international community of responsible zoos running co-operative breeding programmes. This in line with the World Zoo Conservation Strategy, a masterplan developed by the global zoo network in collaboration with the World Conservation Union." This what really makes captive breeding successful. The teamwork form all the zoos makes it easier to raise populations faster. http://www.zsl.org/education/the-modern-zoo/how-breeding-programmes-work,100,AR.html "While captive populations are established for many reasons, establishing captive populations for saving species from extinction is an important contribution of zoos to conservation." This proves that captive breeding is one of the most important factors in saving species. http://nationalzoo.si.edu/SCBI/endangeredspecies/default.cfm http://learn.genetics.utah.edu/content/tech/cloning/
