Where Are All The Stars? The Ecological Consequences of Light Pollution

Light pollution – it’s the result of man-made light used ineffectively and excessively and a consequence of industrialisation. In the US, wasted light costs more than 4.1 billion dollars and spews approximately 21 million tonnes of CO2 into the atmosphere each year. This light is the sort we use to light our buildings and streets, but which shines outwards into the environment, rather than inwards. Artificial light doesn’t just affect stargazers, but has dire ecological consequences. Dr. Kellie Pendoley from Pendoley Environmental joined The Daily to discuss the work of her leading marine conservation biology consultancy.
