Have you ever noticed how at night, you can see the stars shining so brightly in the sky? Well, there is an organization called the International Dark-Sky Association or IDA, which thinks it's important to be able to see the stars at night.
The IDA is like a group of people who want to help us see the stars by making sure that the places we live in, like cities and towns, have less artificial or man-made light. They want to keep the sky as dark as possible so that we can see lots and lots of stars and space objects like the Milky Way.
This is important because too much artificial light at night can create problems for people, animals, and the environment. For instance, it can disrupt our sleep or confuse animals' nighttime schedules. So, the IDA works to make sure that lights are used in a smart way and only when we need them. They also promote using special kinds of lights that don't affect the nighttime environment as much.
In a nutshell, the International Dark-Sky Association is a group of people who believe that seeing the natural beauty of the night sky is important, and they work to protect it by promoting responsible outdoor lighting practices.
