Forests play a huge role in human life.Recently, their number on Earth has been reduced by almost half. A man cuts down trees for his needs, not paying attention to what destroys a forest and all its inhabitants.
The most extensive forest zone of our planet andthe richest source of oxygen is taiga. It extends south of the tundra over a large territory of Siberia and the Far East and stretches across almost the entire Northern Hemisphere. Taiga is in Finland and Canada. It occupies more than a third of all the forests of the planet.
Taiga plants are not very diverse.In the southern part of the zone, many relict species have survived, but some of them, due to man’s fault, are on the verge of extinction. For their preservation, the Cedar Span Reserve was created on the shores of the Amur Bay and the Ussuri Reserve.
The soils of the taiga are not very rich in humus and often ondeep frozen. Winter in these lands lasts a very long time, and only conifers, mainly cedar, fir and spruce, can survive, mosses and lichens grow on the soil, which often form a thick carpet. There is almost no underbrush in the taiga. A lot of precipitation falls out, which flush nutrients from the upper layer. These soils are also called podzol for their light color.
Moose, deer, wolverines, beavers, bears and wolves are the most common inhabitants of taiga. There are also many fur animals (mink, sable, marten, ermine), which are exterminated because of their valuable fur.
The most valuable plant found only ina taiga, - the Siberian cedar. Furniture, pencils and musical instruments are made from its wood, nuts and juice are used in medicine, and cedar oil is also very useful. Other common taiga plants are pine, larch and fir. They are also used by man in traditional medicine.
If a person continues to cut down the forest uncontrollably, then soon there will be no places that enrich the entire planet with oxygen.
