"Touching coral can disrupt their natural habitats and getting too close to aquatic animals, including sea turtles, can cause changes to their feeding and mating habits," d'Auriol explained. "Not to mention the damage that common sunscreen can have on the coral reefs." Back in 2016, the cruise line contributed $100,000 to complete an educational handbook for travel companies offering shark and ray tours. To ensure they are keeping in line with best practices when it comes to ocean wildlife, RCCL has also entered into a five year partnership with the World Wildlife Fund's (WWF) ocean tourism and coastal conservation projects, to advance ongoing conservation efforts and continue to drive sustainability within the tourism industry. However, the local activist claimed this partnership in particular, hardly touches on the environmental impact the cruise line's fleet of ships has on the oceans, as cruise ships often use bunker fuel, which is thousands of times dirtier than the average diesel used to fuel trucks.
