RIO DE JANEIRO, BRAZIL - Sounds can be beautiful, like the bioacoustics sounds produced in the Amazon Rainforest where animals, emulating musicians, perform independent parts and make specific voices that complement each other forming a glorious symphony. Or the installation "Sounds of the Earth", by Doug Aitken, where you can hear the bowels of the Earth live in Inhotim, Minas Gerais.
Unfortunately, not only beauty comes from sound, but great distress and pollution as well. In Rio de Janeiro at least sixty percent of the complaints received by the Municipal Commission for the Environment (SMAC) are related . . .
