The Green Whale

Save the .

Whales and dolphins are remarkable. But why are they so important? Why do we need to end captivity, stop whaling, prevent deaths in fishing gear, and protect their homes, the oceans and rivers of the world? What is so special about whales and dolphins?

Whales play an amazing role in an ecosystem that keeps every creature on Earth alive, including you!

Humans have done enormous damage to the planet including killing millions of whales and wiping out up to...


...of some populations.

Yet few people, let alone governments, are aware that recovering whale populations can help fight the damage we cause.

How whales support the marine ecosystem.

Whales act as giant marine 'ecosystem engineers'. They re-distribute nutrients across the seas; essential to the marine eco-system, and the production of phytoplankton, which produces over half of the world’s oxygen. This is known as the "Whale Pump".

Whales as ecosystem engineers - the Whale Pump

You can make a big impact on one of the world’s biggest challenges, by getting behind the world’s biggest creatures.

Whether you are an individual or a company find out how by supporting WDC you can help solve the climate crisis.

Different species of whales feed on a range of marine creatures, including krill and fish, in the dark depths of the world’s oceans.


Whales then come up near the surface to poo – and when whales poo, they really poo.

Whale poo is a brilliant fertiliser for microscopic plants called phytoplankton.


More whale poo means more phytoplankton.

Phytoplankton absorbs carbon from the atmosphere – millions of tonnes of it.

Carbon in the atmosphere is a significant cause of climate change.

Climate change is the greatest threat to all life on Earth.

So, the more whales there are, the more phytoplankton there is, and the more carbon is taken out of the atmosphere.

Even in death, whales sustain life.  When whales die they sink to the seabed, where they become mini-ecosystems sustaining all manner of marine life, taking huge amounts of carbon with them to the sea-bed. Researchers estimate that because of whaling, large whales now store approximately nine million tonnes less carbon than before large-scale whaling.
