Enhancing the Dark Sky

Description

This presentation focuses on the issue of light pollution and ways to mitigate its effects through responsible lighting practices. It explains the causes and impact of light pollution on the environment, wildlife, and human health. Topics covered include:

- Light pollution causes: Outdoor lighting, streetlights, and commercial lighting contribute to skyglow, glare, and light trespass.

- Measurement: the Bortle scale is used to quantify the brightness of the night sky.

- Effects on wildlife and ecosystems: Artificial lighting disrupts nocturnal wildlife, ecosystems, plants, and trees.

- Human health: excessive light exposure affects circadian rhythms and mental health.

- Solutions: strategies for reducing light pollution include using lower colour temperature lights, focusing illumination only where needed, and using proper controls like dimming and motion sensors.

- IDA Certification: the presentation highlights International Dark-Sky Association (IDA) approved products and their role in reducing light pollution.
