It seems like you owned a paradise Island in just few days. A journey to Koh Ngai is one of the best adventure. Based on the pictures captured, your right the place have healthy, nutritious, heavenly Environment there live a beautiful creatures, where sea is crystal blue and the fresh air would definitely plunge us to quench. I never had an experience to visit caves and it seems to me a scary place, but as what I have seen in this content it's just like where treasure hide. Treasure is not always about precious limes and stones, for me it is the heavenly nature that would take a lot of story to be there, that's why we should protect the nature for it allow us to experience the world's wonders and the future people could still experience what we have seen. It is a very sad thing when we tell a story to our future son/daughters of how beautiful nature is, when we can't afford to have it literally. We are lucky bout how we experience to climb on forest tress, dive and drink in fresh crystal water, breath fresh air, pick fruits, see the healthy underwater water corals, and many more. What we do now makes an effect bout tomorrow. We could help save the world through small ways that count's when all of us would work for it. We should stop on doing selfish activities will lead nature to death.

Happy Mother's day to Everyone <3
