How many batteries are thrown away each day?

There are hundreds of batteries that are thrown out because we don't use all of the power that are in them and when we throw them out there is always a bit of chemical left inside them that we do nit know about. When we throw a battery away that has been in our kids toys and they stop working than we throw them we out thinking that it could ruin our stuff, and new battries the=at have never been used will start to leak and will also ruin our stuff so we throw out hundreds and hundreds of batteries that are throw out in the world everyday.
