Patrick Geddes was a really smart guy who lived a long time ago. He liked to look at cities and how people lived in them. He thought about things called "bioregions", which means the natural things that make a place special, like mountains or rivers or forests. He also thought that people and cities should be part of nature, not separate from it.
He had lots of cool ideas about how to make cities better, like having different areas for living, working, and playing. He also thought we should respect the environment by using resources wisely and not making too much waste.
Overall, Patrick Geddes wanted people to live in harmony with nature and each other to make the world a better place.
