Usually, research on certain subjects is like this. The results of the research are frightening. What is going to happen in the future? What is actually happening? But now scientists have recently done such research. That too on blue whales. Going into the real matter. Recently, scientists have noticed a significant decrease in the voices of blue whales. According to National Geographic, some special microphones designed to record sounds at the bottom of the sea were sent into the sea. However, what was revealed through these microphones is that. Scientists have noticed a significant decrease in the voices of blue whales. However, these microphones sent into the sea not only track the life of marine creatures but also tell us how they survive. These microphones will help us understand how human activities affect different species.
The reason for the significant decrease in the sounds of blue whales is. It has been found that extreme ocean heat waves have damaged the whales' environment, as well as caused a chain reaction in the marine food web. It has been found that these heat waves have led to toxic algal blooms, which have not only poisoned marine mammals but also wiped out key food sources such as krill and anchovies. It is also the most widespread poisoning of marine mammals ever recorded, said john Ron, a biologist at the Monterey Bay Aquarium Research Institute. He said that the sounds of blue whales have decreased by about 40 percent compared to the past decades. Blue whales sing when they are hungry to find food. He said that the sound of these blue whales has decreased a lot during such singing. However, he said that the problem started in the Pacific Ocean in a warm water area called The Blob. The problem was first identified in 2013. Then by 2016, it had grown to a huge area more than 2000 miles long, he said, and this was due to rising sea temperatures.
He said that due to the increase in sea temperatures, blue whales are not getting food, and these ocean heat waves are affecting the ecosystem.  He said that due to this, blue whales eat less food and make less effort to reproduce, and as a result, the blue whale population is gradually decreasing. Also, science says that human activities are causing climate change, which will have a serious impact on the oceans. But he said that future generations need to learn a lot from these oceans. john Ron said that the change in the voice of blue whales is frightening scientists.
