Title text: The Watership Down rabbits removed an additional 0.1 nanometers constructing their warren, although that was mostly soil. British rabbits have historically mined very little coal; the sole rabbit-run coal plant was shut down in the 1990s.
Who will join me on my next eco-friendly venture, to smear the entirety of the UK with 3 inches of coal to restore it to its natural state? (What, you want to know where we'll get the coal? Don't worry about that.)
