Each autumn, the monarch butterfly travels thousands of miles as it migrates from Canada to Mexico. It's a long trip, and the butterflies need plenty of milkweed to survive. But Christopher Puttock says milkweed supplies are growing scarce.
Puttock is a botanist with the Monarch Sister Schools Program, an initiative that helps build butterfly gardens at schools. Today, he's at West Education Campus in Northwest, D.C., where Jasmin Henderson is a third-grader. She says she's happy to see her school help out the butterflies.
Monarch Sister Schools has built eight butterfly gardens in D.C., and 18 nationwide.
