Forest - is an important component of our planet.It is not only home to many animals and birds, but also affects the lives of people.
What is the forest for the modern man
What does the word "forest"?We all know from childhood that it is a lot of different trees, which are quite close to each other.It is nice to relax and enjoy the fresh air.But in reality, a real ecosystem with multiple occupants, which depend on each other.Here harmoniously cooperating plants with insects, animals, birds, and even bacteria.They occupy a significant portion of the total land and spread over 40 million square kilometers!
There are three types of forests: coniferous, deciduous and mixed.From the territory in which they grow depends on their nature.In temperate latitudes deciduous trees shed their foliage with the arrival of cold weather.But in the humid and hot parts of the Earth that does not happen, and the forest is lush from year to year.Evergreen trees in the world the most, and they generate the bulk (80%) of oxygen to all the earth.These figures confirm the importance of forests for the modern man.
direct impact on people
Forest performs many functions that man constantly uses.In addition to maintaining the environment, it remains an important natural resource.But above all, the value of the forest for the modern man is conditioned by his participation in the process of photosynthesis.Without him there would have been possible to develop the oxygen, and life on Earth would stop.
In addition, it is worth considering that today, thanks to technological advances, the world stepped forward.But precisely because of this, the air is filled with chemical fumes and pollution.Vegetation is struggling with these phenomena, and absorbs some of the emissions, which is why the value of the forest for the modern man today is simply invaluable.Also, the energy of trees able to influence the human psyche in a positive way.
Indirect effects also
forest reflected on the water regime of the territory in which it grows, and is located near it.The soil in the area has a special "litter", which is capable of cleaning liquid that has passed through it.Wood gives the purified water, which reduced the bacterial content of about 70%.
also value the forest for the modern man is that he is able to mitigate climate.In places where it grows during droughts or dry winds trees reduce this devastating effect.Thanks to this protection are stored agricultural crops, which otherwise would have been destroyed by bad weather.Plantations have both a positive effect: they protect the soil from landslides, mudslides and other geological hazards.
forest resources and their use
But the importance of forests for the modern man is not limited to its effect on the environment.His riches are many resources.In addition to wood, people get valuable vegetation, which is used in pharmaceuticals, cosmetics and cooking.A total of forest materials a person receives about 30 thousand species of all kinds of products.
most common thing derived from forest resources, is paper.Because it is produced magazines, notebooks, books, napkins, cardboard, textiles and building materials.Znachanie forest for the modern man is very important.Without these resources, even a simple paper would be considered a huge deficit.
Today there Distillery, which are made from wood material paints, silk, alcohol, plastic, food and more.Among other things, is a fuel timber.
Deforestation
So that means the forest for the modern man and how closely it is intertwined with our lives?Population growth and its needs are reflected in the fact that an increasing number of regular logging.Scientists have made a calculation and found that the average person in his life consumes 100 cubic meters.timber.
To meet the needs of humanity, made deforestation.But beyond this reason, there are other factors which lead to destruction of vegetation.This includes targeted land clearing for construction and pastures.Also, it is cutting the places where there are deposits of underground resources.In addition, often there are fires, which killed hundreds of hectares of forest.Each year, the planet loses about 13 million hectares of vital vegetation.After such an intervention is not restored forest.The reason for this is the work of humans.In the liberated areas "grow" the city, or the plantations are used for farming.Today, the issue is discussed on a global scale.It is known that about 80% of all living creatures inhabit it in the tropical forests, which are subject to special destruction.If not stopped, cutting reflected not only in the disappearance of rare species of fauna and flora, but also the viability of humanity as a whole.
