You might cover your house in decorations and go OOT but nothing quite says it's Christmas like a well-decorated fir tree. The problem is... many variations can be a bit of an eco-nightmare. According to research done by netentcasino a typical 6 1/2 ft artificial tree has a carbon footprint equals to about 40kg of greenhouse gas emissions… which is more than twice than that of a real tree ending in a landfill. Artificial Christmas trees are often marketed as greener options, but if they're plastic then it's likely they'll just end up in a landfill.
