Once Upon a Time

Once Upon a Time provides scientific information in a manner that is simple enough that even a young child can enjoy and understand. The story is told through the adventures of three young girls who live on a tree farm in Oregon. They learn from their kindly neighbor, a scientist, that carbon dioxide (CO2) is the miracle molecule that is necessary for life on earth to exist and that increasing CO2 is helping plants to grow faster and bigger.
