Finnish engineers have poured pig manure into a contaminated pond next to an old mine, saying the bacteria in the slurry will clean up metals in the water.

Mining company Outokumpu dumped 450 cubic meters of pig slurry into the waste water near the closed Kangasjarvi mine, which once produced zinc, copper and sulfur.

Thee mouse turned to the pig, "I am so sorry Mr. Mouse, but the trap is no concern of mine either!" the pig said.
