Artificial lighting has its place in our world and is invaluable to businesses, homes, roads and recreation. However, when used inappropriately or excessively, artificial lighting can cause light pollution. This has adverse effects on the environment, our health, biodiversity, and our climate (through energy waste). Light levels in Ireland have increased by ≈60% over the period 1995-2015.
