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.Without a population of whales, the krill on which they feed would multiply exponentially; in turn, krill will deplete the populations of phytoplankton and algae on which they feed, causing an imbalance in the marine ecosystem. Whales also play a role in carbon capture and help regulate the planet's climate.Whales act like a pump that recirculates the fish and zooplankton that they've ingested toward the surface in the form of nitrogen-rich fecal matter. These nutrients are essential to the primary production of the marine ecosystem. Whales are sentinels of the health of marine environments.
How do whales help the world : They play a vital role in the health of the oceans where they help provide up to 50% of our oxygen, combat climate change and sustain fish stocks. The way that whales feed, poo, migrate, and dive between the surface and the ocean depths (known as the 'whale pump'), circulates essential nutrients throughout the ocean.
Do whales really save humans
Whales and Dolphins: complex behaviours from complex species
There are also well substantiated reports of whales and dolphins grieving for their dead, even rescuing humans.
Why are whales so valuable : Whale oil and baleen (sometimes called whalebone, although it's not bone at all) were valuable commodities. Whale oil comes from the blubber of right and bowhead whales, and the head cavity of sperm whales. It was used primarily for oil lamps. Corsets and hoop skirts were constructed from whalebone.
Historical research paints a much different picture, but today, modern research shows us that whales are and always have been typically a friendly species. Today when whales are spotted, their relationships with humans are now amicable, social, and inquisitive. Because of their intelligence and social nature, orca whales are unlikely to attack humans out of aggression or hostility. In fact, there have been numerous instances of orca whales coming to the aid of humans who were in danger, such as when a group of orca whales helped a diver escape from a shark attack.
Why do we need blue whales
Whales are ecosystem engineers and play an important role in stabilizing the marine food web. A single blue whale can consume up to 6 tons (12000 lbs) of krill in one day, which has a major impact on maintaining the balance of ocean ecosystems.Heithaus said in most cases, whales and dolphins are probably not protecting humans for altruistic reasons — more likely they are trying to protect themselves or their young.Japanese whalers continue to hunt Minke, Bryde´s and Sei whale in the North Pacific. Until its recent announcement Japan used the loophole of so-called 'scientific whaling' to side step the IWC ban . . . and the meat is sold on the open market. Gray whales
Gray whales also have the reputation of being the friendliest whales in the world. They are curious about boats and will often approach them and check out the humans aboard. Near Mexico, a gray whale actually played with a boat of tourists by lifting the vessel onto its back and briefly swimming away with it.
How do whales treat humans : Whale attacks on humans are extremely rare, despite the fact that they can be harmful at times. Whales are typically relatively solitary creatures, so even if they are dangerous or aggressive, people are rarely in close enough proximity to be hurt by them.
What happens if whales go extinct : Worsening Climate Change
In the absence of whales, krill would likely eat much of the free-floating phytoplankton on the ocean's surface, resulting in a marked acceleration in climate change. Some whales actually feed on phytoplankton, however, so this relationship is not as clear as it might seem.
Are whales important to save
Additionally, whales also provide a balance to the ocean's ecosystem, regulating food supply and keeping a check on the overpopulation of prey. You may be surprised to hear, but whales are also very important to the economy of developing countries – all because of whale watching. “If someone told me this story, I wouldn't believe them…” While out filming, whale scientist Nan Hauser was suddenly faced with the largest tiger shark she had seen in her life. That was until a whale lead her back to the safety of her boat.Whaling is illegal in most countries, however Iceland, Norway, and Japan still actively engage in whaling . Over a thousand whales are killed each year for their meat and body parts to be sold for commercial gain.
Why does Norway hunt whales : Whales are mostly hunted for the consumption of their meat, some of which are exported to established markets in Japan. Despite the low demand for whale meat within and outside the country, Norwegian politicians and fishermen try to keep the practice alive and even expand this market.
