It's hardly imaginable, but every year, about one billion batteries are used up in Germany alone.
Strung together, this line of batteries would cover the circumference of the earth (one billion x 4 cm = 40,000 km).

Almost 70% of all flat batteries still end up as domestic waste. This amount of toxic substances could poison the whole of humankind. After us, the Deluge?
