With pine trees!
We plant pine trees to make paper and cardboard. The wood is turned into cardboard at paper mills. Pine trees are used because they grow so fast!
With corn!
We use corn to make glue that holds the layers of cardboard together, creating a strong box that keeps your pizza piping hot.
With soybeans!
The words on the box are sometimes printed with inks made from soybeans.
