    Silvia is working to balance social development and community-building with environmental conservation, focusing on sustainability over the long term.

Unlike the United States and Australia, which carefully control nonnative vegetation, Brazil has neither public policies nor legal limitations on the growth of species that degrade the quality of soil and crops.
