Why do people plant poplars, while knowing that their fluff will fly everywhere and bring harm to some categories of people?

Poplars are just monoecious plants, they have the rudiments of both male and female principles .... but due to poor ecology, poplar can "change sex" so boys planted at the beginning are transformed into girls, producing dust.

In general, poplars are a dioecious breed, that is, they can be both male and female. The funny thing is that the fluff only flies from female poplars. Attention, question * sound of gong * Why are women planted trees?

Poplars are leaders in the production of oxygen, relative to their other colleagues in the shop. In addition, their leaves very actively emit phytoncides that disinfect the air (which is a natural antiseptic for the city). Plus, it is not whimsical to the soil and grows quickly. Of the minuses - only down, which burns perfectly and collects allergenic pollen from flowers and plants.
People plant poplars, because they are a unique plant, thanks to which we do not spit out our lungs in industrial cities and megalopolises.

Advantages of poplars:

1) Long-lived (40-60 years, sometimes 120)

2) Not picky about the soil when cultural planting.

3) Wide area of ​​growth

4) They have an aesthetic appearance

5) The vertical position of the poplar trunk.

6) It continues to grow, even if the tree breaks or is sawn off top.

Now tell me, what tree can replace poplar on the streets?
