I've read fake christmas trees often contain lead and that the pvc used in making many of them also is toxic and can off-gas. how safe is it to use an artificial tree? would prefer real, but am avoiding shopping in public right now due to covid?

Xmas Trees: I understand your concerns, but these same concerns can be said of many other products we use or already have in our homes. Xmas trees are usually sold outdoors, and with a proper face covering and glasses and maintaining a six foot distance from others, the chances of catching COVID is quite small. Pick a time during the day without crowds to shop, buy real, and have a safe and Happy Holiday.
