Like humans, plants and animals possess a body clock that regulates rhythms of activity throughout the day and across different seasons. Artificial light not only disrupts the body clocks of wildlife, it can also affect plant growth, pollination and reproduction, and animal migration, predation, and communication.
Actions we can take to reduce harmful effects of blue light on plants and wildlife:
Be aware that plants and animals are also sensitive to light; some are strongly affected by blue wavelengths whereas others may be more strongly affected by other colours.
Use outdoor lighting only when and where needed and ensure light does not spill into unintended areas.
Change the colour of outdoor light by filtering or by changing the light source if it will benefit species in your area.
