Actually as that tree's cut down another is planted in it's place. Unless you cut it from the wild, and around here at least that just opens up space for another to grow into.Hiya
Real tree or fake .... a fake one takes more plastic and metal materials to make but gets reused; a real one means a CO2 absorbing tree is killed and disposed of when it could have grown up to be a nice table or bed. To stop the needles on a real tree making a mess spray it liberally with lacquer. or clear wood sealant.
