Artificial light has become increasingly strong: now a streetlight gives off twenty times the light of the moon.
Some experts believe the unintended consequences of artificial light at night:
- endanger marine turtles trying to make it to sea
- confuse insects responsible for pollinating plants
- increase stress in people exposed to constant illumination
- make it harder for individuals, especially children, to get to sleep because light suppresses the production of melatonin, the sleep hormone.
This Australia perspective makes the case that artificial light at night “is becoming as much of a threat to the health of the planet as holes in the ozone layer.”
You have probably heard about how global warming might affect you. But how might the unintended consequences of artificial lighting have an impact on your life?
