Read the introduction of a speech given by a park ranger. this is going to be a beautiful week at windswept dunes, and i hope you enjoy all the beach has to offer. there is a unique opportunity available because sea turtles are nesting on our northern shore. volunteers are needed to patrol the beach to protect these endangered creatures from lurking predators. you can make a difference by just taking a stroll on the beach at an assigned time. while enjoying the view of the ocean at night, you can clap your hands or whistle a tune to discourage raccoons and possums from disrupting the turtle habitats. the author’s purpose in writing this speech is to persuade listeners to perform volunteer work. inform listeners about organized beach activities. inform listeners about the life cycles of turtles. entertain listeners with stories about beach wildlife.
