Asbestos, Lead, Mercury, and Radium were (and in some cases still are) commonly
used materials. They have properties that make them super useful for various tasks,
like heat-resistant insulation or self-luminescence. However, they've all been found
to cause death in various ways. As science and work place safety advance, will we
continue to find out that materials around us will kill us? Can we ever trust that
our environment won't cause us harm? I don't know, and I don't seek to answer such
a heavy topic in this talk, but come find out about things that we now know to be harmful!
