Some people believe that real Christmas trees are a fire hazard because they can be dry and brittle, which makes them more likely to catch fire. However, this is not necessarily true. Real Christmas trees are only a fire hazard if they are not properly maintained and cared for. If you keep your real Christmas tree well-watered, it will remain moist and less likely to catch fire. Additionally, real Christmas trees are treated with fire-retardant chemicals, which further reduce the risk of fire. So, if you take proper care of your real Christmas tree, it should not be a fire hazard.
