People love to travel not only for the food and culture. They also travel to see sights around the world they would never see in their hometown. Visiting the island of Socotra in Yemen can seem like you’re on another planet. More than 30% of the island’s plant life, including the dragon blood tree that bleeds bright red sap when it’s cut, isn’t found anywhere else on earth. It sounds like a once-in-a-lifetime experience to see something as fascinating as this. Furthermore 37% of Socotra’s plant species, 90% of its reptile species and 95% of its land snail species do not occur anywhere else in the world besides this UNESCO World Heritage Site.
