Hayduke

Okay, so imagine there's a book called "The Monkey Wrench Gang" and it's about some people who really care about the environment and want to protect it. One of the characters in the book is named George Washington Hayduke and his friends call him Hayduke for short. They all work together to stop bad guys from hurting the land and animals that they love.

So when people talk about Hayduke, they might be talking about the character from the book, or they might be talking about someone who is inspired by the book and wants to do good things for the environment too. It's kind of like a nickname or a symbol for people who want to make the world a better place.
