Since her nose has immeasurable amount of unused space which can be used for tree plantation. Those trees will grow faster as she produces natural dung in her brain. So basically it will just grow all by itself without any effort. She can alone prevent global warming by growing large trees and spreading oxygen around Dhaka city. It’s being considered by many scientists all over the world.
