Migration and Its Importance

The video explores the concept of migration, focusing on why animals like monarch butterflies, purple martins, and salmon migrate. Monarchs return north to lay eggs on milkweed, which is essential for their caterpillars. Purple martins migrate to find abundant food, while salmon swim upstream to lay eggs in safe waters. Despite the challenges, migration is crucial for meeting the needs of these animals and their offspring. The video concludes with a preview of questions for the next episode.
