Peter Gibbs asks whether sound could become a vital tool in conservation, helping us understand far more about how wildlife interacts and how it is affected by changes in the environment . Technological advances in recording mean that we can now record huge amounts of data in remote locations. By using algorithms scientists hope to break down complex interactions between animals and their environment and be able to predict change or protect species. This is the emerging science of soundscape ecology. Scientists are hoping to apply big data solutions learnt from fields such as genetics to re-imagine conservation and asking all of us to listen and imagine what a world without natural sounds such as birdsong might be like.
