The reason that they stopped making Mercury thermometers is because mercury is very deadly, if you where to get it in your eyes you would go blind, also if you where to injest it accidentaly, (unless you where a little kid and didnt know any better), it could have the potential to kill you.
mercury isn't recyclable. so when u throw them away they pollute the ground and mercury is poisonous. its the same reason they stopped making mercury switch thermostats. heres a link with a video on how it acts in an open air environment: http://www.Stanford.edu/dept/EHS/prod/enviro/Thermometer_replacement.HTML

Why are digital thermometers used these days?
Digital thermometers have replaced mercury thermometers because mercury is toxic. [Personal commentary: digital thermometers are not accurate and mercury thermometers are so how many people are being harmed by not knowing their temperature versus how many would be harmed by the mercury if accurate thermometers were still used?]
