Farmers find a way to turn a profit off milkweed, for the sake of the monarchs

Milkweed has long been considered a nuisance on North American farmlands but now, more than 100 farmers in Quebec and Vermont are planting it in their fields to help restore the declining population of monarchs, which use that plant exclusively for their eggs and to feed the caterpillars. The farmers are also tapping a new market for the milkweed fibers. After the caterpillars have their fill of the milky sap and find their wings in the fall, the plant’s pods will be harvested for fine winter clothing and other commercial uses.
