By talking about facing global warming, we always focus on increasing greenery, but what about a creature that can absorb tons of carbon dioxide during its lifetime and when it dies it sinks to the bottom of the ocean and takes with it what it carries of carbon dioxide? Every large whale catches about 30 tons of carbon dioxide during its lifetime, which ranges from 30 to 90 years, while during the same period a tree contributes only to three percent of carbon dioxide absorption compared to the whale. However, these organisms face many risks due to humans.
Whale hunting began from prehistoric times to obtain oil for lighting, leather, soap, and to benefit from their meat as well, since hunting a large whale is equivalent to hunting a thousand fish. As a result of the excess, the percentage of whale hunting exceeded the sea stock of whales, which led to the exposure of some species to extinction.
As a result, commercial whale hunting was prohibited in the year 1986 by International Whaling Agency, but did this succeed in recovering the sea stock from whales? Japan has not stopped hunting whales, citing its use in scientific research, but it is surprising that it has ended up in fish shops.
Whaling Agency with the aim of resuming commercial fishing, as whales are an important source of protein, while most Japanese assert that they eat them rarely.
It is non-target whaling while hunting other marine creatures. This occurs through fishing nets, and some whales, dolphins, and porpoises are the victims of it. Catching whales occurs accidentally in fisheries, but are retained due to their value as food.
This type of fishing is expected to increase due to population growth and the heavy needs for fish meat. Bycatch is one of the main causes of the death of marine creatures.
Climate change, of which humans are one of the causes, affects not only humans but also marine life. The high temperature affects fish reproduction, especially krill, “small shrimp”, which the whales feed on. That is, a person is always a cause, whether directly or indirectly.
Since man has known sailing, the sea started to be shared between ships and whales. So, to what extent is shipping a threat to whales? The movement of shipping traffic is in increase, in addition to inflated volume of ships and the increase in their number that interfere with the whale and dolphin paths, despite the size of the whales and their speed, but they cannot exit the ship's path in a timely manner, which exposes them to injury or death, and this is one of the reasons that the whales are subjected to extinction and especially the weak ones. Ship engines, mining and drilling work cause high levels of underwater noise that affects whales' communication causing them to lose their group, and long exposure to that noise may cause hearing loss.
In exchange for what the whales offer us, to maintain the balance of marine life and confront global warming, we made them a risk for their survival end up being exposed to extinction. So, it is real that there is a direct relation between saving whales and saving the planet. Blue whales must stop suffering anymore and it’s our responsibility.
