Now researchers are focusing more and more on space exploration and removing objects in the universe than in undeveloped areas of the earth.
Even if the planet is unexplored areas. Such places are the real "white spots". Although not quite white, but gray – that's for sure.
It is the largest forest in the world. It lies on a flat, almost flat surface of 5.5 million square kilometers. Half of the planet's tropical forests are in the Amazon Basin. In these forests often on the expedition, and every time scientists discover a previously unknown species.
But these forests are not for tourists. Almost all plants, insects and animals that want to kill or at least mutilate have come here.
The central part of the country is the highlands to the west to the Atlantic, the Namib Desert stretches, to the east is the Kalahari Desert, in the northern jungle, and to the south the Orange River. For 825 thousand square kilometers of the country, its population is only 2.3 million. So that in wide areas almost untouched by humans.
Kamchatka, Russia  The population density on the peninsula is even lower than in Namibia. On the area of 270 thousand square miles live only 300 thousand people. The beauty and attractions of Kamchatka exceptional – volcanoes, geysers, lakes, rivers, bays. But the harsh winter of the territory of Kamchatka is practically deserted.
The Greenland Ice Sheet It occupies 80% of Greenland. It stretches 2400 km from north to south, its widest width is 1,100 km and the ice thickness in this area is more than two kilometers on average. So the ice is still very unknown. For example, in 2013, NASA discovered under the ice of Greenland a canyon twice as long as the Grand Canyon in the United States.
Papua New Guinea
This state is located on the same island, which occupies half of the island (the other half of the island belongs to Indonesia). Dense tropical jungle, almost complete lack of roads make the area impassable. But for scientists there is a great deal of scope for research – after all, 2/3 of all the local species are endemic.
Sakha Yakutia, Russia
The Sakha is a huge area in Northeastern Siberia. By area it is almost equal to India. But almost all of its territory is covered with permafrost. Under these circumstances live plants, animals and humans.
