A study of pictures of Earth by night has revealed that artificial light is growing brighter and more extensive every year.

Between 2012 and 2016, the planet’s artificially lit outdoor area grew by more than 2% per year.

Scientists say a “loss of night” in many countries is having negative consequences for “flora, fauna, and human well-being”.
