New Zealand is rich in geothermal resources, especially in the hot spring town of Rotorua, hidden a world-class national park ---wai-o-tapu geothermal park, where there are pits left after volcanic activity, all over the boiling mud, like the gate of hell, It is a landscape that nature has formed over 100,000 years. In the park, you will smell a strong smell of rotten eggs. This is a unique smell of sulfur. Most of the plants are smoked and distorted. But there are other plants that thrive here. There are even birds that crawl flat on the mud with such a high surface temperature to find insects foraging. You will be amazed at the vitality and the magical power of the earth.
