Start off with some potted plants and maybe some water bowls to decorate with. Then if you can afford it, purchase furniture that is made with more all natural components like bamboo.
How about studying witchcraft before performing spells! No self-respecting witch will just hand you over a spell. Especially for something so mundane....how about YOU make the call?
Since most of the tampering was done in the early years of archaeology the only real reason is human error. People simply didn't realize that their handling techniques were destroying the artifacts. Others couldn't care less and wanted to destroy it out of greed. Sorry, there is no conspiracy...
