Dark Skies are not only a problem for astronomers. They also cause problems for migrating birds and insects.
Read about the problem of dark skies from the articles below. If you are installing external lights, pay attention to the fixtures and install the fixtures and wattages compatible with dark skies concepts.

For billions of years, all life has relied on Earth’s predictable rhythm of day and night. It’s encoded in the DNA of all plants and animals. Humans have radically disrupted this cycle by lighting up the night.

Plants and animals depend on Earth’s daily cycle of light and dark rhythm to govern life-sustaining behaviors such as reproduction, nourishment, sleep and protection from predators.

Scientific evidence suggests that artificial light at night has negative and deadly effects on many creatures including amphibians, birds, mammals, insects and plants. Light Pollution Effects on Wildlife and Ecosystems, The International Dark-Sky Association
