Parks and trees are of paramount importance in urban environments, as they contribute to air purification and oxygen production. In this way, they can protect the population from many unpleasant and serious diseases, provided they are present in sufficient quantities.
It is not only the number of parks and trees that matters, but also their quality: the leaves of carefully selected trees can trap up to twice as much dust and pollutants. In addition to choosing the right tree species, it is also essential to maintain green spaces, as only healthy trees can contribute to air purification in the long term.
