With the group, Valle Carlo was involved in several initiatives, including protesting the use of El Yunque forest by the US Armed Forces.
He was instrumental in the acquisition and creation of the Centro Interpretativo, a visitor's center that offers tourists free guided tours to the surrounding forest and natural preserve.
[1] Valle Carlo also spearheaded the initiative to save Isla de Ratones (Mice Island), a small key off the coast of Cabo Rojo that is rapidly losing its surface area through erosion.
The couple, and a group of local volunteers, incorporated Arte en la Plaza Betances, a unique community group dedicated to bringing art to the urban center of Cabo Rojo, specifically the Ramón Emeterio Betances plaza at the town's center.
The group sponsors a yearly art open air exhibit and competition of young local painters as well as other activities, such as a concert by the Arturo Somohano Philharmonic Orchestra at the Betances plaza.
