(Photo: iExplore) Not only beautiful and peaceful, this island also owns a mysterious lake called Jellyfish Lake – Jellyfish Lake. Until now, science has not been able to explain why there are millions of jellyfish living here. (Photo: Flick) Jellyfish Lake is up to 12,000 years old, and probably has existed since the ice age. About 12,000 years ago, when sea levels were at their peak, seawater flooded the area and filled the lowlands to form present-day Jellyfish Lake. Until the glaciers recede, the jellyfish and fishes have no place to live, they just freely grow in the lake, eat all the algae and gradually develop into unique jellyfish species, creating unique species of jellyfish. so the ecosystem is very diverse. (Photo: ABC News) (Photo: The Travel) There are only 2 types of jellyfish living here: golden jellyfish (scientific name is Mastigias papua) and moon jellyfish (lunar jellyfish – scientific name is Aurelia), the most crowded is the yellow jellyfish. They need sunlight to grow and survive, so they will move from east to west in the direction of sunrise and sunset. Until dark, they will dive deep to the bottom of the lake to rest, and so on this cycle repeats throughout the jellyfish’s life. (Photo: iExplore) To get to Jellyfish Lake, from the pier, visitors will have to cross a rather long slope. Right at the right time to stop to rest, the dark blue Jellyfish Lake also appeared in front of everyone. To observe jellyfish in the lake, visitors are only allowed to swim, snorkel and mask. Everyone has a strange feeling when swimming and interacting with countless jellyfish around: It’s quite ticklish, but it’s also very enjoyable. (Photo: Lonely Planet) (Photo: Reddit) (Photo: Viator) Although both species of jellyfish have stinging cells, they are generally not strong enough to cause injury to humans, so swimming in the lake is safe. This is not a big obstacle for adventurous travelers. Because the opportunity to swim in a space filled with golden jellyfish like this is something in life that not everyone can enjoy. Therefore, despite having to pay a lot of money, but every visitor coming here is very eager to experience swimming with these special lovely jellyfish.

The Republic of Nauru is an island nation in Micronesia in the South Pacific Ocean. With approximately 12,000 inhabitants living on an area of ​​21 square kilometers, Nauru is the smallest country in the South Pacific Ocean, and the third smallest in the world by area. However, the island nation was once rich enough to rival Saudi Arabia thanks to its abundant phosphate deposits made up of bird droppings. Bird droppings accumulated centuries ago on this island. Phosphate is an important ingredient in fertilizer production. The huge reserves of phosphate on the island of Nauru are the result of bird droppings (guano) over several thousand years. Because phosphates are located close to the ground, humans can separate them easily. Nauru’s economy peaked in 1975 thanks to revenue from phosphate mining, when the island’s GDP per capita was estimated at $50,000, ranking 2nd in the world. Nauru’s economy boomed, people lived better without having to fish or cultivate or gather. Western lifestyle is also spreading here, making the locals more and more lazy and like fast food. With a huge amount of money from mining, Nauru built an airport, even bought 7 planes to serve traffic and tourism. “Not many people care about whether the investment is profitable or not. Dollars are even used as toilet paper. Life was like an everyday party,” recalls an unnamed former president of Nauru. As resources dried up and investors withdrew, Nauru was left with heavy environmental pollution and no main source of income. The fishing and agricultural sectors have been abandoned and polluted, while the people are too used to a life of enjoyment. To get the phosphates, workers had to peel off all the topsoil and separate the phosphates from the ancient coral columns. So, after the phosphate disappeared, only tall coral reefs and depressions between them were visible—a type of terrain where humans could not live or plant trees. The value of the investment fund managing the island’s resources also decreased. The fund also made many misguided investments in Air Nauru and overseas hotels. These investments never yield returns and even stifle the domestic economy. In Nauru, visitors will have nothing to visit because this island has only 30 km of roads, no museums, cultural heritage, hotels or even rivers and mountains to explore. Every year, only about 200 visitors come to Nauru and they are mainly social activists or scientific researchers. From a rich country, using dollars to make toilet paper, Nauru fell to a poor island nation with a GDP of only about 102 million USD, the second lowest in the world after Tuvalu. About 90% of Nauruans are unemployed and corruption and money laundering are rampant. The people of Nauru instead of finding their way to economic development, they leave their fate to international aid as well as look for cheap imported food sources, which contain a lot of fat and sugar such as low nutrition, from Australia or New Zealand.
