Irrlicht
I am concerned about the adverse effects of artificial light on biodiversity. By exploring how excessive light pollution disrupts the delicate balance of ecosystems, I'm hoping to shed (just enough) light on the often-overlooked impact of light pollution on our natural world.

How Artificial Light Disrupts Ecosystems
Research has established that light pollution disrupts the natural photoperiod (day/night cycle) of plant and animal life. This disruption leads to a cascade of negative effects across ecosystems.
Plants may experience delayed dormancy, altered flowering patterns, and reduced growth. Similarly, wildlife can suffer from disrupted breeding cycles, disorientation during migration, and increased predation risk due to the loss of natural darkness.
These combined impacts weaken plant and animal populations, ultimately leading to a decline in overall ecosystem health and biodiversity. The economic costs of light pollution are still being fully understood, but the ecological consequences are already demonstrably significant.
Christmas lights on lavender disrupt its natural growth cycle and causes stress or damage to the plant. Heat generated by the lights increases humidity levels around the bush, creating a favourable environment for mould and fungal growth. The winter cover traps moisture, which can lead to rot or disease.
As one of the most illuminated nations worldwide, the Netherlands is taking a stand against excessive light pollution. The Nacht van de Nacht initiative aims to create a darker, more sustainable environment.
