Alcohol is bad for the liver because it can cause severe damage that will in turn result in a build up of scar tissue. This impacts the whole organ system because it can slow down the metabolic processes that rely on the liver. The liver's job is to store nutrients for when cells need them. However, the liver also takes harmful things like alcohol or drugs and turns it into something that is not as harmful for the body. Too much alcohol consumption will take its toll on the liver and overwork it. That is why alcohol causes so much damage to the liver.
