An example set of answers might be: “I take part in Globe at Night. Every so often after nightfall I go outside and record how bright the artificial lights are and what stars I can and can’t see. By doing this I hope to demonstrate that levels of artificial lighting in London are far above what is necessary for our safety at night, and that the situation is deteriorating and unhealthy. Perhaps it will encourage future policy makers to take local wildlife into account and allow us to sleep better.” But your answers might be very, very different.
