Detailed explanation-1: -When they die, they sink to the bottom of the ocean, taking the carbon with them. According to the study, each great whale sequesters around 33 tonnes of carbon dioxide on average. A tree during the same period only contributes to 3 per cent of the carbon absorption of the whale.
Detailed explanation-2: -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.
Detailed explanation-3: -Blue whales require enormous amounts of food, but they’re a boon to rather than a burden on the ocean ecosystem. Their iron-rich poo is a really important source of nutrients in the marine food chain, promoting Southern Ocean productivity, which boosts fishery yields.
