Song whales goes out, it: This article explores the topic in depth.
Therefore,
Song whales goes out. Meanwhile, it:
For years the scientific community has used “hydrophone”, kinds of micro aquatic, to study underwater fauna. Nevertheless, These devices allow you to record a large number of sounds, including those produced by blue whales.
But for some time, scientists have worked. Nevertheless, The whales are increasingly silent. Additionally, Nevertheless, In a study, published within the journal PLOS One, CO Author John Ryan returns to this phenomenon. Similarly, According to him, the whales would simply be … For example, starving.
Hungry whales – Song whales goes out, it
Recent waves of heat have deregulated the fragile marine ecosystem. In warmer water, toxic algae were able to develop. However, this caused mass stake in the Krill. Launching a chain reaction that strikes the whales head -on. Because the Krills are their main source of food.
In fact, the songs of the blue whales fell 40%. And the situation should not song whales goes out, it improve. The first surveys on the temperature of the oceans were made in the 1940s. Compared to these data, the heat waves are today three times longer. However, it is precisely this persistence that rebalances the ecosystem to this point.
For Dawn Barlow, an ecologist of the State University of Oregon, this lack of food could be double -edged. If the whales spend all their time feeding, they will no longer try to reproduce. They will therefore die of hunger on one side. and their population will doubly fall because of a decrease fertility rate.
The fate of our planet depends on the whales?
According to the words of the scientist Kelly Benoit-Bird. co-author of this study and marine biologist of the Aquarium of Monterey Bay we could quickly reach a “rocking point”. According to her, you should not only be worried about whales, but for the whole planet.
With song whales goes out, it ever warmer water, the oceans will be less and less able to store carbon. However, they are today the first source of natural capture of this greenhouse gas.
At a time when we write these lines, 39,000 carbon gigatons (GTC) are stored in the oceans. For comparison, the atmosphere is made up of 750 GTC. Every year the oceans by absorbing approximately 2.4 GTC. But this natural phenomenon is based on a very fragile balance, highly disturbed by climate change.
The fragile balance of carbon in the oceans
By being absorbed by the oceans, carbon dioxide (CO2) is transformed. It becomes carbonic acid and releases carbonate ions. In this form, it reduces the pH of the oceans. In normal times. it serves as a regulator and makes it possible to compose the increase in the pH caused naturally by the marine fauna and flora.
But because of global warming. carbonate song whales goes out, it ions are more and more numerous, and at the same time, marine ecosystems are more and more poor. As a result of the oceans are acting, which decimates the hopes present in sea water a little more.
A vicious circle which seems innalarce. unless the human species ceases (very) quickly to pollute the planet which serves him as a house.
