butterflies on the decline... I got this one solved... BUTTERFLY GARDENS AT HIGHWAY VISITOR CENTERS AND AT PUBLIC SCHOOLS

it is really that simple
provide the ecosystem 
milkweed and butterfly bushes
that simple

in the schools it would be ascetically pleasing and educational
then at the highway visitors center
it would also be pleasing to the eye as well as educational
if I were a kid... i would want to stop at the Rest Stop with the butterflies on the family road trip

Butterflies

I planted a butterfly bush and a milkweek plant at John  Eaton Elementary School after I hosted a Bike Swap there some years ago
