A tax of one cent per ounce of soda has been proposed to generate revenue and curb over consumption of the sugary staple beverage. Also, many schools across the country are currently restricting or banning the sale of sodas in vending machines on their campuses. According to the California Center for Public Health Advocacy, a 20-ounce serving of soda contains around 17 teaspoons of sugar, and a child’s risk of obesity increases by an average of 60 percent with every additional serving of soda. “Bubbling Over,” a recent study by Yale University’s Rudd Center, reported that 41 percent of Santa Cruz children and 56 percent of Santa Cruz teens drink one or more soda or other sweetened beverage a day.
