Artificial Christmas trees may seem like a good idea at the time, but you should check out the disadvantages of having this kind of tree before you make your decision. One of the biggest complaints about artificial trees is that they are not fire retardant. They catch on fire fast, so you will want to make sure your tree and lights are working correctly. PVC plastic is what these kinds of trees are made of. In some older trees, you may find that lead was used to make it. This is unhealthy for you and your family. Since these trees are made from PVC plastic, they can’t be recycled and would stay in the landfill.
