Section 1
Excess Light Overwhelms Animal Senses
Key Idea
An animal's environment can change in ways that affect its senses. Extra light from cities and buildings creates light pollution in areas that are normally dark at night. This change can get in the way of an animal's ability to survive.
This new light acts as a form of environmental interference. For animals with very sensitive eyes, the bright light can overwhelm their specialized sense receptors. When these receptors receive too much information, the brain cannot form a clear image of the world.
