Why are monarch butterflies disappearing?

ST. LOUIS (KSDK) – Monarch butterflies are disappearing.

It's a fact that isn't being disputed – although the causes vary. Experts point to the increase in cropland leading to the destruction of milkweed – the common host of monarch caterpillars.

Experts also say some herbicides and fewer plants means less food – which means fewer butterflies. This could directly affect humans' food supply.

After bees, butterflies are the second largest pollinators.

To help, experts recommend planting milkweed in your backyard. If you plant some milkweed, experts say, and your neighbors also plant some, the habitat eventually expands throughout your neighborhood.
