PEMBROKESHIRE Coast National Park Authority, Pembrokeshire County Council and Natural Resources Wales are encouraging members of the public, businesses and organisations to join a county-wide effort to reduce light pollution.

As well as giving people a clearer view of the dark skies above, reducing light pollution can also benefit wildlife and improve your health.

There are eight designated Dark Sky Discovery Sites in the Pembrokeshire Coast National Park.

These are some of the best places to experience the night sky, away from areas where the stars are obscured by light pollution, but are easy to access.

Park Authority Health and Tourism Policy Officer Hannah Buck said: “It is difficult to capture in words the experience that people gain from looking up at the sky on a clear night in a place that is free from light pollution, where the stars and the magnificence of the Milky Way can be appreciated.

“Light pollution not only obscures our ability to see the stars, it also wastes energy which in turn can lead to increased levels of greenhouse gas emissions. This has been proven to have a negative impact on human health and can have significant impacts on wildlife.”

One of the simplest ways to show your support for the effort to reduce light pollution is to take part in Earth Hour, which will see lights across the globe turned off from 8.30pm-9.30pm on March 30.

Businesses and landmarks around the world also take part in the initiative, switching off their lights to help make a noise for the Earth Hour movement.
