We do not even think about how firmly established the word "tree" in our life with you.This creation of nature helps to survive mankind since its inception: burning, it warmed rights;prepared food on the fire;of flexible branches were making bows and arrows;trunks more powerful and durable rocks were to build a house and furniture.
Today wood is used more actively than a few centuries ago.In a rapidly growing population and demands are growing rapidly.What accounted for the life expectancy of the trees at such a rapid and devastating deforestation?And take into account at all?What will happen to humanity through the nearest hundred years?
Just imagine hectares of forest a day is able to absorb 250 kg of carbon dioxide, instead of giving 250 kg of oxygen and coniferous trees - three times more!So, mankind has consciously deprive themselves of the opportunity to breathe, so - the possibility to survive.But this is only part of the top of a huge iceberg of the coming catastrophe.
condition of the soil and climate in general also depends on forests.It delayed planting and forest streams of water after rain and melting snow;It was in the woods the most fertile soils formed for decades and are the result of the decomposition of fallen leaves;namely the forest is a haven, a home and a place of most food animals, birds, insects and plants.
Where there is no wood, water flows down to the riverbeds, without stopping, washing plants, eroding soil, forming gullies.Moisture left in the river, not returned, which means that the ground is lacking, not allowing the plants to grow, which once pleasing to the eye.All living things, devoid of the house or out in the other, still preserved forests or dies.There comes an imbalance which results predicted and sounds like a death sentence: the desert ...
How much effort and how much time it will take for the restoration of our descendants ruthlessly exterminated natural wealth?After all, the life expectancy of the trees is not always great, and the life, alas, nebezlimitny.This means that some species of trees have or will not see our grandchildren, not even our children.
particularly alarming minimum lifespan of trees.For example, it sinks to less than 60 years (usually - 20).For poplar, aspen and alder - 150 years.This suggests that some of the trees can be cut down before they can bear fruit and multiply.The result - a complete extinction of the species.
course, longevity of oak is much higher - up to one and a half thousand years.But even if you give birth to a new oak woods now, it will take at least a hundred years old, will begin to recover until the microclimate on the site of the felled forest.And attention is focuses on the word "begin."
a similar picture emerges, if we take another tree.For example, the life expectancy of European stone pine (and also already disappearing) - 1000 years.A little less.Just think: what dragged to light 1,000 years, we are ready to destroy, in whole for half a century!
silent, submissive trees that give us shelter, food, warmth, and many more benefits disappear completely in half a century!You're only 50 years old.That such a figure called environmentalists.
take individual countries for clarity.In England there is already 5% of forests in Spain and France - about 15%, in Bessarabia - about 5%.In place of the once noisy green oak forests today is the desert ...
And what became Northern Black Sea Coast, famous for once virgin lands, beech forests and oak groves?Today, it represents a meager steppe, windswept.
example of respect for the wealth of the Earth for us to become ancient civilizations.Their representatives have a clear understanding of the need to preserve forests.Even the Babylonian king Hammour, for example, a law was passed about their preservation.Then the cutting of trees is punishable by death.Later, Thales and Aristotle were written great works of the need to respect for nature, about possible changes in the climate, follow after the barbaric felling of trees, on the environmental disaster in general.
But now few people know about these works.About how the forest affects the climate, it was written before the revolution: "... they influence the humidity, precipitation, temperature fluctuations, forest reduced the average annual temperature is moderated by a decrease and an increase in temperature as a whole in the forest falls more precipitation, moisturerecycled soil is much denser ... ".
Are we reasonable people, completely forgotten about his mind, losing the sense of reality, and thoughtlessly hasten to the precipice, dragging the coming generation to replace us?We have reduced the average life expectancy of trees in dozens of times.How can we are surprised at the sudden change of climate, drying up the seas, the formation of a huge desert?Perhaps by the terrible disasters earth, writhing in its death throes, he is desperate to return to us the mind, defending the last breath from her flooded "parasites"?
