South America is the fourth but the largest continent on Earth. Its Northern shores are washed by the warm waters of the Caribbean sea, and the extreme southern tip of the island of Tierra del Fuego, divided between Argentina and Chile, lies in a cold, stormy Atlantic ocean. On the continent presents a great diversity of landscapes and climatic zones. Hot dusty steppe of the pampas stretch through the cattle country of Argentina and Uruguay. In the West tower of the mighty Andes, with cool fertile valleys, where coffee grows. Hot tacama desert of Northern Chile is one of the driest places on the planet. In Brazil, in the Amazon basin, the stretch impassable green jungle. There are in South America and vast lakes, and tall waterfalls, and rocky Islands.
The most humid of the continents. High mountains causes a variety of climates, the presence of altitudinal zonation. Equatorial zone occupies the Amazonian lowlands and the North-West coast. In the tropical zone of the Eastern part is influenced by the trade winds, on the coast of a lot of rainfall (2,000 mm), the difference in summer and winter, t minor. In the interior the rainfall is considerably less (1000-500 mm). The Pacific coast is under the influence of the cold Peru current. Here is one of the driest places in the world (the Atacama desert).

Since late 20-ies, substantially increased the attention to environmental protection. Now, not only environmentalists, but also ordinary people think in order to make a contribution to the preservation of the ecological system of the Earth.
Simultaneously with the development of tourism there was such a thing as ecotourism. It’s not just trips or tours to national parks and reserves. Ecotourism cultivates the correct attitude to nature, eco educates and promotes the preservation of pristine nature.
Frustrating is the fact that ecotourism is a little-known pastime for citizens of the former USSR and in the West it is widespread. The main purpose of this type of tourism is not to harm the nature.

The size of a giant bowl with a bright pink water reaches up to 3 sq. km. the Maximum depth does not exceed 3 meters.
The name of the lake derives from the special color of the water, which ranges from light pink to brown. The reason for the unique color of the water is a large amount of cyanobacteria in the lake are ancient organisms that appeared on Earth 3.5 billion years ago. Surprisingly, except for them in this saturated salt solution no other organic life. The salt concentration in the lake Retba almost 1.5 times more than in the Dead sea – 380 grams per liter. Salt production takes place since 1970.
Now people extract the salt, standing to his neck in water, but 20 years ago the lake was moving without boats, the water level reached the belt. But because mining a huge amount of salt (about 25 thousand tons per year), the depth of the lake was rapidly increasing.
Every morning dozens of local men with the necessary equipment, floating in the middle of the lake and climb in very salty water. They break the salt deposits at the bottom Continue reading
