The Swiss "New Seven Wonders of the World Foundation" announced the preliminary selection results through its official website. Seven regions, including Brazil Amazon, Halong Bay in Vietnam, Iguazu Waterfall in Argentina, Jeju Island in South Korea, Komodo National Park in Indonesia, Principessa Underground River in the Philippines and Table Mountain in South Africa, ranked in the top seven in the statistical results and won the honor of "New Seven Wonders of the World". Now let's look at them one by one. 1, Brazil Amazon Amazon rainforest, also known as Amazon primeval jungle, originated about 55 million years ago, when it was in the period of global cooling, resulting in humid climate in northern and central South America. At present, the Amazon rainforest is the largest tropical rainforest on earth, distributed in 9 countries, with an area of 7 million square kilometers and a forest area of 5.5 million square kilometers. Amazon rainforest has the largest number of biological species in a single tropical rainforest in the world. Known as the "lung of the earth", the Amazon rainforest is not only a storage place of carbon, but also a supplier of oxygen, which has a positive effect on the climate all over the world. It has irreplaceable functions such as biological reservoir, botanical garden and zoo. At present, the Amazon rainforest is about 6.5438+0.73 million square kilometers-nearly one-third of the area is officially protected. The unique pink puffer fish, colorful "poison arrow" frogs and Indian tribes in this area have never touched the modern world, which is extremely rare.
