This publication by UN Environment contains a joint editorial from the UN Environment magazine “Our Planet”. The issue demonstrates, through contributions from leading authors, how environmental risk factors such as pollution, chemical contamination and climate change bring disease and death. The publication emphasizes the importance of reducing environmental threats in order to improve human health. Relevant work carried out by UN Environment and its partners in this area is also highlighted. The publication provides a clear view of how environment and health are closely interlinked. It also features great articles on sanitation, cookstoves, climate change changing the disaster landscape and how natural resource degradation (like falling trees) can exacerbate disease burden.
