How whale poop is helping save the world
Naturally, like all other vertebrates, whales too need to poop. After satisfying their hunger in the deep waters, they swim to the surface and excrete. What a lot of poop that would be in proportion to their size. But whales are always on the move, migrating across miles of ocean. Thus, their nutrient-rich poo — containing nitrogen, phosphates and other minerals — also gets distributed over vast distances, fertilizing the ocean and boosting the growth of phytoplankton, the microscopic plants that float on the water.
Why they're important
The inconspicuous phytoplankton are the heroes of the ocean. They absorb immense quantities of carbon dioxide and release oxygen. It is believed that more than half of our atmosphere's oxygen comes from phytoplankton. Thus, they not only provide pure air for life in the ocean but also on land. Whether you live next to the coast or in the remote interior, out of every five breaths you take, three breaths you owe to the ocean. Beyond this, the phytoplankton sequester humongous amounts of carbon dioxide and enable the ocean to serve as a carbon sink.
Carbon dioxide is the major greenhouse gas, which prevents the sun's heat from escaping away from the Earth. In the last few years, human activities have been spewing unimaginable quantities of this gas into the atmosphere. The phytoplankton, along with plants on land, need to thrive in order to carry on their role of absorbing carbon dioxide.
If it weren't for whale poop, phytoplankton would not thrive as much and there would be far more carbon dioxide in the atmosphere than at present. Just imagine, how much hotter summers would be. Thus, the all-important whale poop is actually saving the world by allaying climate change.

Top 10 Heaviest Animals In The World
Last Updated: August 06, 2025, 19:16 IST Blue Whale: The largest and heaviest animal to have ever lived, reaching up to 150 tons and over 100 feet long. These marine giants feed primarily on tiny krill, consuming up to 4 tons of it daily. (Image: Canva) African Elephant: The heaviest land animal, weighing up to 14,000 pounds. It is known for its intelligence, complex social behaviour, and massive ears that help regulate body temperature. (Image: Canva) Fin Whale: Second only to the blue whale in size, the fin whale can weigh up to 80 tons. It is incredibly fast for its size, earning the nickname "the greyhound of the sea." (Image: Canva) Sperm Whale: The largest toothed predator on Earth, with males weighing up to 125,000 pounds. It is famous for deep diving and its use of echolocation to hunt giant squid. (Image: Canva) Right Whale: They can weigh up to 70 tons and are known for their enormous heads, which make up about a third of their body length. They are slow swimmers and were historically easy targets for whalers. (Image: Canva) Bowhead Whale: They weigh nearly 100 tons and is adapted to life in Arctic waters. It holds the record for the longest-lived mammal, with some individuals estimated to be over 200 years old. (Image: Canva) Asian Elephant: It is slightly smaller than its African cousin, weighing up to 12,000 pounds. It is revered in many cultures and is distinguished by its smaller ears and more domed head. (Image: Canva) White Rhinoceros: Weighing up to 5,000 pounds, the white rhino is the largest of all rhino species. Despite their bulk, they can run up to 30 mph and are crucial for maintaining grassland ecosystems. (Image: Canva) Hippopotamus: Hippos weigh up to 4,000 pounds and spend most of their time in water to keep cool. Although they appear docile, they are highly territorial and considered one of the most dangerous animals in Africa. (Image: Canva) Indian Bison: The largest wild cattle species, weighing up to 3,300 pounds. Native to South and Southeast Asia, these massive bovines are muscular, shy, and usually found in forested habitats. (Image: Canva)

How whale poop is helping save the world
It is common knowledge that whales are the largest animals on the planet. Among these, the Blue Whale tops the list. The adults are about 30m and weigh around 200 tonnes. Imagine how much food they will need! Their food comprises very tiny crustaceans called krill. It is a paradox: the largest animals depending on the tiniest prey. The manner in which they feed is intriguing. They swim to the depths of the ocean and gulp huge quantities of water. This is filtered out through the many plates (baleen) in their cavernous mouth and the krill is left inside. The Blue Whale, Grey Whale and Hump-backed Whale are among the Baleen Whales. Other whales such as the Killer Whales or orcas hunt seals, sea birds and fish and have different hunting tools: their large conical teeth. Naturally, like all other vertebrates, whales too need to poop. After satisfying their hunger in the deep waters, they swim to the surface and excrete. What a lot of poop that would be in proportion to their size. But whales are always on the move, migrating across miles of ocean.

6 animals that are known for their unbelievable weight
When we talk about the animal kingdom, it's usually about speed, hunting skills, or sharp instincts. But there's another side to wildlife that's just as fascinating– size. While some animals grab attention with their looks or behaviour, others stand out simply because of how massive they are. Tired of too many ads? go ad free now From deep oceans to forests, some animals stand out simply because of how heavy they are. They may not be the quickest or the most dangerous, but their size plays an important role in nature. Here's a look at six of the heaviest animals in the world– creatures you won't forget once you know their weight! Blue Whale The blue whale isn't just the heaviest animal alive– it's the heaviest animal in Earth's history. Found in oceans across the globe, a fully grown blue whale can weigh between 130 to 150 tonnes. Surprisingly, they survive by eating tiny krill and often travel long distances while migrating. Whale Shark The whale shark is the largest fish in the world and can weigh around 18 to 20 tonnes. These giants are slow-moving and usually found in warm, tropical waters. Even with their massive size, they're completely harmless to humans and are often seen swimming near the surface, feeding on plankton and small fish. African Elephant The African elephant is the heaviest land animal, with adult males often weighing over 10 tonnes. Found in different parts of Africa, they're known for their intelligence, close family groups, and long lives. They also help shape their environment by knocking down trees and digging water holes that benefit other animals too. White Rhinoceros The white rhino can weigh up to 4.5 tonnes, making it one of the bulkiest land animals after elephants. Known for their wide mouths and grazing habits, white rhinos are mostly found in parts of southern Africa. Tired of too many ads? go ad free now While their numbers are more stable than other rhino species, they still face threats from poaching. Hippopotamus The hippopotamus usually weighs between 3 to 4.5 tonnes and is mostly found in rivers and lakes across Africa. Though herbivores by diet, hippos are known for being highly territorial and are considered one of the most dangerous animals on the continent. Southern Elephant Seal Among seals, the male southern elephant seal stands out for its massive size, weighing close to 4 tonnes. Found in colder parts of the Southern Hemisphere, especially near Antarctica, these seals are known for their deep-sea diving abilities and loud roars during mating season.
