Today, for anybody not a secret that humanity uses barbaric wealth of the planet, at the same time, not only taking away everything that is possible, but also to destroy the rest.
's why deforestation in our time has become one of the most important environmental problems.After all, if we continue at a pace to exhaust "light" of the earth, then very soon it will not remain a single tree.
And what will become of us?After all, forests are not only enrich the surrounding atmosphere so necessary oxygen, but also the main driving force in the process of the water cycle.They pick up moisture from the soil, and then filtering and purifying it, released into the atmosphere, thereby increasing the humidity.
damage that causes deforestation is so great that the planet faces global warming, becausewith their increasing reduction in the amount of greenhouse gases.
Of course, for a man of enormous economic importance of the forest.The wood used in the manufacture of more than twenty thousand different products.This plastic and synthetic rubber, and alcohol, and fertilizers, and paper, etc.
However, consider the use of forests only in the materialistic aspect is very wrong.Human life is impossible without them as possible without nature.
problem of deforestation is developed in parallel with the history of mankind, and what goes on technological advances, the more the question arises once the deforestation of our planet is very green.And the gradual development of the infrastructure - roads, towns, agriculture - very strongly stimulates the process.
Deforestation just vital for agriculture, but in fact it, and rather primitive nature inflicts a lot of damage very, burning the trees in order to enrich the soil.
Forests are traditionally divided into three groups.
The first group includes those who perform sanitary and water protection and recreational functions are protected areas, in short, are important ecological functions.Deforestation in this group is strictly forbidden.
The second group includes those who have a limited operation.They are also important for the environment and are in densely populated areas with developed infrastructure.They cut down a part, while carefully watching the timely recovery of felled trees.
A third group - a production forests, which can be cut down completely, and in their place must be planting new seedlings.
Russia is largely dependent on forests in its territory.In addition to raw materials for industry and valuable wood, is more than a hundred kinds of berries, fruits and other plants, about 200 different species of edible and medicinal trees and shrubs, as well as fungi.They can add a huge amount of game birds and animals that live in them: sable, squirrel, marten, beaver, capercaillie, grouse, etc.
Scientists estimate that about 80 percent of all species of flora and fauna of the planet are found in tropical forests, harvesting of which leads to the destruction of ecosystems and the extinction of many plants, although some of them are essential components of many life-saving drugs.
According to a recent UN report, global deforestation continues to grow rapidly.Every year destroyed more than 13 million acres of green space, with their only half filled.This means that every day the face of the planet disappears forest the size of a football field.
Although in Asia a few years ago began to increase green areas, but the consequences of deforestation is still being felt.
human history already knows quite a lot of sad examples that show the consequences of irrational and barbarous deforestation, when the once green and vibrant area can suddenly turn into a lifeless, uninhabited wilderness, where people are living becomes impossible.A striking example - the death of civilization on Easter Island.
