Steve Tonkin is the Dark Sky Advisor to Cranborne Chase National Landscape, in Wiltshire. Cranborne Chase is a designate Area of Outstanding Natural Beauty that, since 2019, has been recognised as an International Dark Sky Reserve.
Steve can pinpoint 4 October 1957 as the first became aware of dark skies. His family were, at the time, living 8 miles outside Bulawayo, Zimbabwe and his father took him outside to see if they could see Sputnik which had been launched the previous day. It was his first time looking up at a pristine dark sky and it triggered a life-long passion for astronomy which has made him aware of the effects of light pollution, and he has been raising the issue with anyone who will listen for the last 30 years.
After a first career as a telecommunications engineer, he did a BSc in Human Environmental Studies, then postgraduate work in technology policy, before training as a teacher. He taught physics, maths and astronomy in a variety of settings for 35 years, before retiring from teaching to concentrate on astronomy outreach activities. He has written several books on practical astronomy, has a monthly column in BBC Sky at Night Magazine, and is a regular speaker on astronomical topics.
Starting with a programme he made for BBC Radio Bristol in the 1980s, Steve has long been an advocate of reducing light pollution. He supported the Cranborne Chase’s International Dark Sky Reserve bid as a volunteer, taking sky quality readings and supporting the stargazing evenings by giving talks and showing people the night sky. His primary task as Dark Skies Advisor is to continue and consolidate the good work that has already been done and strengthen the Cranborne Chase’s standing as an International Dark Sky Reserve.
Light pollution is a global issue. The pollution itself is known to affect human health and wildlife behaviour and that is before considering the wasted energy involved in sending light upwards instead of downwards to where it is required. To take a Biophilic approach to the design of lighting is to reduce light pollution with direct and indirect benefits to nature… READ ON and LISTEN to the PODCAST…
