The monarch butterfly population is dwindling due to a decline in milkweed. Monarch butterflies only lay their eggs on milkweed, and caterpillars only eat milkweed. Since 1990, monarch populations have crashed, with nearly 1 billion of the butterflies dying.

The decline isn't due to natural causes. Pollution-driven climate change is part of the problem. Sometimes milkweed is cut down in order to build houses, buildings and streets. In recent years wildfires have destroyed a lot of milkweed.

Last year N.C. State University held an event to plant milkweed habitats to help monarch butterfly populations grow. To learn more about how you can help the monarch butterfly visit the Monarch Butterfly Sanctuary Foundation at
