Which country started from bird droppings?

The country that started from bird droppings is Nauru.

Nauru is located in the middle of the Pacific Ocean, about 4 1 km from the equator in the north, 4 160 km from Hawaii in the east, 4,000 km from Sydney, Australia, across the Solomon Islands in the southwest and 306 km from Kiribati in the east.

It is an oval coral island with a total length of 6 kilometers, a width of 4 kilometers, a coastline of about 30 kilometers and a total area of 24 "? . For thousands of years, countless seabirds have come to inhabit this island, leaving a lot of bird droppings on the island. Over the years, bird droppings have undergone chemical changes.

It becomes a layer of high-quality fertilizer with a thickness of 10 meter, which is called phosphate rock. Three fifths of the island is covered with phosphate, except for a narrow flat land along the coast.

Extended data:

Nauru mainly relies on the exploitation and export of phosphate to maintain the high income of its residents, with an average annual income of $8,500. Per capita GDP ranks first in the South Pacific.

Nauru has invested a lot of real estate abroad in order to improve the situation of relying solely on the income from phosphate rock and prepare a way out after the phosphate rock is exhausted in the future. The fiscal revenue mainly comes from the huge income of phosphate rock and long-term foreign real estate investment.

Nauru is rich in phosphate resources, and exporting phosphate to Australia and New Zealand is the main source of income. In the 1970s and 1980s, its annual output and export volume were about 6,543.8+0,000-6,543.8+0.5 million tons. Since the 1990s, the output has been declining year by year.
