How whale song and human survival are connected

by simon

A new study on whale voice boxes shows how they can produce such complex sounds. But naturally, there are limitations to how loudly they can sing and the implications of this are vast for our own existence on Earth. How whale song and human survival are connected is a fascinating journey through the complexity of life that I cover in my book Wildlife in the Balance.

If we threaten the structural integrity of the soundscape it’s like moving the television into the office or the dishwasher into the living room. The complex acoustic scaffolding that wildlife produces is critical to ecosystem function. Animals are building rooms for themselves … we might call these ‘territories’. These are places where they can live in peace, and if we upset this, we destroy the ambience, increase anxiety and create conflict.

Quote from Wildlife in the Balance.

Communication between animals makes culture more stable

The language between animals like whales is not one we can understand. But we don’t need to. Culture is developed exactly the same way as ours through communication between individuals and societies. This ultimately leads to a balancing of ecosystems and the services on which we have built human civilization for the last few hundred years.

At the end of the day we are just another animal and our basic needs are clean air, water and food. The systems of noisy transport we create are not, of themselves, an evolutionary stable strategy as they don’t make the essential life support we need. We still depend on having animals as part of that ecosystem.

This is how whale song and human survival are connected. It’s why we cannot afford to allow whales not to hear each other … without this, we cannot survive.

Whales create a better climate for living

Sperm whales are the only species with individuals with that have a biologically world-wide home-range. Their entire life is spent listening for food and they would once have had a profound impact on our climate. Climate is simply the end-point of a system where energy is otherwise absorbed into providing food, clean air and water. Natural climate systems are built by animals.

Blue whales too, have a huge impact on our weather systems. They make the difference between bush fires and floods in Australia.

Sperm whales are among the world’s biggest (also in terms of body size) amplifiers and transporters of nutrients in the oceans, but have declined by as much as eighty per cent from pre-whaling numbers of 1.1 million animals. They are among the largest creatures to have ever lived and are the only animals that regard the whole of the world as their home range.

Quote from Wildlife in the Balance.

It’s one of the many reasons why the strapline of my book is ‘animals are humanity’s best hope’.
