Rainforest protection is not only good for biodiversity and the climate – it also noticeably improves the health of humans who live in the corresponding regions. This is the conclusion drawn by a current study by the University of Bonn and the Universidade Federal de Minas Gerais in Brazil. In this, the researchers show that measures to combat slash-and-burn techniques significantly reduce the concentration of particulate matter in the air. The number of hospital stays and deaths due to respiratory diseases thus also decreases. The results have been published now in the journal Nature Communications, Earth & Environment.
