It has been observed that when humans keep in touch with the natural world, their health may be better, although the contact is no more than seeing flowers, trees, shrubs, and birds through a window.
On täheldatud, et kui inimesed on kontaktis loodusega, võib see parandada nende tervist, kuigi see kontakt piirdub vaid lillede, puude, põõsaste ja lindude silmitsemisega läbi akna.
