Two scientists are calling on researchers, NGOs, and governments to begin studying the impact of burning forests and peatlands in Indonesia on the already-threatened marine ecosystems of Southeast Asia. Every year, Indonesian farmers set forests, vegetation, and peatlands alight to clear them for agriculture, often palm oil, and pulp and paper plantations. Not only do these practices destroy hugely-diverse tropical forests, but the resulting haze spreads to many parts of Southeast Asia, threatening regional health and impacting economies. Now, a new paper argues that the sinister impacts of Indonesia’s burning may extend as far as the oceans.
