G20 leaders attend side events at Bali's mangrove forest Tahura Ngurah Rai

G20 leaders have planted trees at Bali's mangrove forest as a symbol of efforts to preserve the environment. Tahura Ngurah Rai is located in Bali, Indonesia, where this year's G20 is being held. For thousands of years, the mangroves there have evolved to cope with the salty, harsh environment.
