Monarchs: Planting Milkweed Isn't the Answer?

We Americans like the simple technological solutions to problems.  (We American analysts like to over-generalize.)

Recently people have been planting milkweed to help the endangered monarch butterfly.

Now comes a report (from my alma mater) which says it's not so simple. Looks like the true causes are going to be harder to fix: lack of nectar in fall, weather, fragmentation of habitat.  Can't see a Kickstarter campaign developing around these.
