Light pollution is a global issue and the situation is becoming worse by the rapid use of LEDs.
LEDs were designed to be an energy-efficient lighting device that could minimise the energy impact for the planet, however, LED is rich in blue colour and is quite harmful to astronomy, health and nature.

The speaker will also talk about different dark sky actions that could act on, including his own example in the heavily light polluted city - Hong Kong.

Sze-Leung Cheung is IAU International Outreach Coordinator heading the International Astronomical Union's Office for Astronomy Outreach in Tokyo.

He is a Chinese citizen fluent in Mandarin, Cantonese and English, and his job is to coordinate and provide support to the worldwide astronomical communities, to help them to make astronomy accessible to a wider public. He was originally from Hong Kong and he organised a light off the event at Hong Kong during 2009.

He will talk at the Starlight Festival about issues of light pollution and star gazing.

He has offered talks in Chinese for our Asian visitors as well as in English.
