Explain how light pollution may affect natural populations. Give two examples

What will be an ideal response?


Ans: The presence of artificial light (light pollution) disrupts orientation in nocturnal animals accustomed to operating in the dark. Newly hatched sea turtles emerge from nests on sandy beaches and orient and move toward the ocean because it is brighter than the silhouette of dark dunes. With increased lighting, they sometimes become disoriented, head inland, and then die. Many migrating birds die in collisions with lighted buildings and towers. Many species of nocturnal frogs and salamanders are also disrupted by light pollution.
