A passionate environmentalist, Davina is no stranger to seeing the beauty of Malaysian waters. As a child, she used to visit the islands with her family and snorkel. Recently, she revisited those spots and discovered that none of the islands look the same anymore. “The ocean isn’t as blue and the corals are colourless,” she explains. “There are only a few places to look for corals and fishes. You don’t see as many fishermen out in the sea.”
