SAO PAULO (AP) — On the edge of Brazil’s Amazon rainforest, the Rovaris family is a symbol of a pioneering success story.

The family arrived in the state of Mato Grosso in the 1970s as part of a wave of agricultural expansion promoted by the country’s then-military dictatorship. In a short span, the Rovaris clan accumulated vast wealth as agronomists figured out how to successfully grow soy in the hostile tropical climate.
