Gisele spoke about sustainable development and “visited projects that implement efficient stoves in communities that have a high number of deaths due to indoor smoke inhalation that occurs by cooking inside their homes without any ventilation,” her official site explained.

Earlier this month, Gisele and her adorable son, Benjamin, were spotted playing at a park in Boston.
