An orangutan walks in an area covered by haze from forest fires at Salat island, Palangkaraya, Central Kalimantan. This year's nearly 2,000 wildfires are burning across Indonesia. It is the worst year since 2015.
Officials estimate that the fires have burned more than 800,000 acres. The smoke and flames threaten endangered species like orangutans that can only be found in Kalimantan and Sumatra.
