Explanation:

The inappropriate or excessive use of artificial light – known as Light Pollution (LP).
The Skyglow is an omnipresent sheet of light across the night sky in and around. Components of light pollution include:

• Glare: Excessive brightness that causes visual discomfort
• Skyglow: Brightening of the night sky over inhabited areas
• Light trespass: Light falling where it is not intended or needed
• Clutter: Bright, confusing and excessive groupings of light sources.

Light pollution can have serious environmental consequences for humans, wildlife, and our climate, in the following ways

• Disrupting the ecosystem and wildlife: Plants and animals depend on Earth’s daily cycle of light and dark rhythm to govern life-sustaining behaviours such as reproduction, nourishment, sleep and protection from predators.
• Harming human health: Like most life on Earth, humans adhere to a Circadian Rhythm — our biological clock — a sleep-wake pattern governed by the day-night cycle. Artificial light at night can disrupt that cycle.

Hence both statements are correct.
