Whales play an important part within the marine ecosystem, and if they were to disappear,
the delicate balance of nature would be disrupted
. Organisms, such as plankton, that feed the ocean food chain also benefit from tons of whale feces floating on the ocean’s surface. …
What would happen if there were no humpback whales?
Were it not for whaling,
the animals might have removed 2 million tons of carbon from Earth’s atmosphere
. In other words, sperm whales fight climate change without trying. … So if the whale population dwindled to zero, that would result in boatloads more carbon remaining in the atmosphere.
Why are humpback whales important to the ecosystem?
Whales play a vital role in the marine ecosystem where they
help provide at least half of the oxygen you breathe, combat climate change, and sustain fish stocks
. … Different species of whales feed on a range of marine creatures, including krill and fish, in the dark depths of the world’s oceans.
How humpback whales affect the ecosystem?
The ecosystem services provided by whales, including
increasing primary production
, directly and indirectly sequestering carbon, and providing nutrients and habitat to myriad marine species, also have an economic value. Such values have been calculated for other species, including bats and pollinators.
Why is it important to protect whales?
Whales are at the top of the food chain and have an important role in the overall health of the marine environment. Whales play a
significant role in capturing carbon from the atmosphere
; each great whale sequesters an estimated 33 tons of CO2 on average, thus playing their part in the fight against climate change.
Where do whales poop?
When a whale releases its excrement the whales poop comes out as an almost liquid form of fecal matter (often in
a plume-like cloud
) and is light enough that it does not sink to the bottom sea but floats across the top of the ocean; in some cases the excrement may also come out in chunks rather than a plume-like cloud.
Why are whales dying?
Although scientists don’t know for certain what caused a die-off of eastern Pacific gray whales, they believe
climate change
might have reduced the amount or quality of prey. Malnutrition could prevent the whales from completing their annual migration and could threaten their general survival.
Do whales save humans from sharks?
Marine biologist Nan Hauser says a 50,000lb (22,700kg) humpback whale protected her from a tiger shark during a recent research expedition in the Cook Islands. She believes it could be the first case on record of a humpback protecting a human.
Why should whales not be hunted?
The future for whales is threatened by countries’
disregarding
and working to lift the IWC’s moratorium on commercial whale hunting, as well as vessel strikes, fishing gear entanglement, ocean pollution (including marine debris), habitat loss and human-created, loud noise.
Why are whales important to the food chain?
Whales are an important part of the marine food chain and play a huge role in maintaining the health of our oceans. … These nutrients, particularly iron and nitrogen, are
vital for phytoplankton
, at the base of the food chain.
How does whaling affect us?
When humans hunt and fish, they tend to
favor animals that provide significant resources
. … This has a negative effect on species and ecosystems, and can also impact the climate: When whales and other large animals flourish in the ocean, they carry a substantial amount of carbon to the sea floor upon dying.
Do whales produce oxygen?
Scientists have called large whales “ecosystem engineers.” Research has shown that
whales cycle nutrients in the ocean
, help create the oxygen we breathe, and play a critical role in mitigating greenhouse gases. Not only breathtaking, whales are also breath-giving.
Do whales clean the ocean?
Through the very process of swimming and diving as well as excreting faeces, whales increase the level of nutrients on the ocean surface, notably iron and nitrogen, which in turn boosts the growth of phytoplankton and marine plants that generate energy through photosynthesis, and in the process remove carbon from the …
Do whales eat humans?
Despite occasional reports of whales scooping people into their mouths, it’s incredibly rare—and for all but one
species, swallowing a human is physically impossible
. On Friday, a lobster diver made headlines when he described miraculously surviving being “swallowed” by a humpback whale off Cape Cod, Massachusetts.
