Our lives depend on trees, because they convert the carbon dioxide that we exhale into breathable oxygen. Forests must be protected, because their area is decreasing from year to year due to the consumer attitude towards them. And everything seems to be leading to the fact that humanity will not take care of this issue until the problem of air purity becomes really acute.
Interesting facts about trees
- At present, about 38 million square kilometers of land on Earth is covered by forests, but this figure is declining every year.
- The largest forest areas on the planet — taiga and South American jungle.
- The most forested country in the world — Finland, about 70% of which is covered with forest. Montenegro is not far behind (interesting facts about Finland).

- The forest really pacifies — medical studies have shown that a person walking in the forest slows down the pulse and evens out the heartbeat (interesting facts about forests).

- 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 jungle alone processes up to 120 billion tons of carbon dioxide annually.
- Trees of different species produce different amounts of oxygen.
- On average, one tree on Earth filters out up to 100 thousand cubic meters of air per year.
- Trees really reduce the greenhouse effect, the main reason for which is 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 ban on plastic bags — only paper ones are used.
- Trees get 8-10 times more nutrients from the atmosphere than from the soil.
