Researchers at Brazil's University of Sao Paulo found that malaria could be kept from spreading while still preserving the biodiversity of the Amazon rainforest. The traditional view is that clearing such forests curbed the spread of the disease. Using a mathematical model, researchers found that the parasite causing malaria was not spread as widely if there were more animals and mosquitoes. "These aspects of biodiversity that can hinder malaria transmission are services provided by the forest ecosystem," said lead researcher Gabriel Zorello.
