PONTE VEDRA BEACH, FL -- A fourth-grader here on the First Coast gave her lunch an extreme makeover and is now the winner of a national energy conservation challenge.

Olivia Horne was curious how much trash the average child generated and began to investigate.

It led to a class assignment, Olivia called it "Extreme Lunch Makeover." She focused on how much trash is wasted in one lunch bag.

Olivia's solution is simple, stop wasting plastic's and start using reusable bags, containers and water bottles.

"Hopefully, it is going to reduce the amount of plastic bottles and bags in our land fills," Olivia said.

Olivia's idea apparently won over more than just friends and family. Olivia beat out over 1,400 other students in a national energy conservation contest.
