Our lives depend on trees because they convert the carbon dioxide we breathe into breathable oxygen. Forests must be protected, because their area is decreasing from year to year due to consumer attitude towards them. And everything seems to lead to the fact that humanity will not deal with this issue until the problem of air cleaning becomes truly acute.

Interesting facts about trees
Currently, approximately 38 million square kilometers of land on Earth are covered by forests, but this figure is decreasing every year.
The largest forest areas on the planet — taiga and forests of South America.
The most forested country in the world — Finland, approximately 70% covered by forests. Montenegro is not far behind (interesting facts about Finland).
The most treeless country in Europe — Great Britain, where forests cover only about 6% of its territory.
The tallest tree in the world — a 112-meter-high redwood growing in the USA.
Sequoias — Basically the tallest trees in the world. And they are also the oldest.
It takes an average of a quarter of a million trees to produce one million tons of paper. An average of 15-20 grams of wood is required to produce one A4 sheet.
Birch – The most common tree in the world (interesting facts about birch).
To save a single tree from being cut down, approximately 80 kg of waste paper needs to be recycled.
The most expensive type of wood in the world — mahogany mahogany. They make expensive luxury furniture and no less expensive musical instruments.
The oldest tree on the planet — a tree growing in a Lithuanian park nicknamed “Old Man” is over two thousand years old.
The crown of an ordinary oak tree grows on average one meter per year.
The forest is truly peaceful — medical studies have shown that walking in the forest slows a person's pulse and stabilizes their heartbeat (interesting facts about forests).
The hardest tree in the world belongs to Schmidt birch. This tree is so strong that it is impossible to cut it with an ordinary axe.
There are approximately 60 times more trees in the world than people.
More than 80% of all felled forests are regenerated partly independently and partly with human help. Yet there are 95 to 97 million fewer trees on the planet every year.
Russia accounts for almost half of all coniferous trees in the world.
Spruce grows up to five hundred years, and pine — up to three hundred and fifty, give or take.
Trees grow throughout their long lives.
The Amazon forest alone processes up to 120 billion tonnes of carbon dioxide per year.
Trees of different species produce different amounts of oxygen.
An average tree in the world filters 100 thousand cubic meters of air per year.
Trees actually reduce the greenhouse effect, which is the main cause of the increase in carbon dioxide in the atmosphere.
Most of the world's paper is consumed in the United States. This is partly due to the country's plastic bag ban. Only paper bags are used.
Trees take in 8-10 times more nutrients from the atmosphere than from the soil.
Trees are very strong. A small sprout is capable of passing even through thick and durable asphalt.
