International Dark-Sky Association (IDA) is an international organization established in Arizona in United States of America in 1988, aiming to preserve the darkness of the night sky by reducing ligth pollution. The organization has already taken lots of actions to achieve the goal, being the first and the largest organization participating in protecting the darkness of the night sky. It has initialized the plan of International Dark-Sky Places around the world, such as USA, Scotland in United Kingdom and Japan, so that the perfect night sky sceneries and environmental conditions can be reserved for future. Including approximately 5000 members in over 70 countries, IDA spares no effort to help educate people about how to restore the darkness during night time and the negative impacts the overlighting at night can bring to humans, including hormone imbalance, high bolld pressure and diabetes.
“We empower the dark sky movement and provide leadership, tools, and resources for individuals, policymakers, and industry to reduce light pollution and promote responsible outdoor lighting that is beautiful, healthy, and functional.”
