While the event is happening, all immigrants arriving to the island will be Environmentalists as many hippies begin to travel across the world to set up hippie colonies.
The hippie counter-cultural movement was based on furthering world peace, civil rights, and protection for the environment. The movement was popularized in 1967, with events such as the Human Be-In and the Summer of Love. Throughout the late 60's, members of the movement went on "hippie trails" to travel across the world, sometimes settling in new countries. By the 1970s, the ideals and traits of the movement had become ingrained in mainstream society and the events that helped start the subculture - like the Vietnam War - were coming to end.
