Marshall Sastra perspective on Shark Diving Tourism: “OK, I, Marshall Sastra, I support the shark research and shark diving tourism in Indonesia and I, myself, wish shark diving tourism – since I am a diver – grows and tourists will come here for shark diving because more people now visit Morotai for shark encounter underwater.” http://www.sharkdivingindonesia.com IG @sharkdivingindonesia @sharkdivingmorotai @ilovehiumorotai @gharonk
