For this month's roundup of environmental news with Macaranga, co-founders Wong Siew Lyn and Law Yao Hua first discuss the Perak state government's decision to go ahead with the lanthanide mining pilot project in Gerik, Hulu Perak, and how the state government hopes to address environmental concerns over the project, before turning our attention to some new research by Coralku, which monitored coral tree nurseries for 414 days, and among other things, found that the most common species used for coral restoration in Malaysia was the worse candidate. Looking forward to September, we discuss the significance of International Day of Clean Air for blue skies on the 7th of September, whose theme this year is “The Air We Share” which focuses on the transboundary nature of air pollution, stressing the need for collective accountability and action.
