As
Christmas approaches, is your organization aware that most artificial
Christmas trees are imported from China and contain lead? I was shocked
to see the warnings on the box when I was considering buying one of
these last year. The warning said the tree contains lead so keep the
tree away from children and children should not touch the tree. I was
really shocked that these trees are for sale everywhere from Costco to
Home Depot.
