The monarch butterfly has seen its population decline sharply since the 1980s. The species, capable of traveling more than 5,000 kilometers across the Americas each year, is now placed on the U.S.
Red List. To reach these forests, these butterflies go through a migratory route strewn with more and more pitfalls. Deforestation, repeated periods of drought, increasingly frequent floods, insecticides and other pesticides which water the crops they cross... In short, this road is becoming dangerous for their survival.
