Altered carbon: the catastrophe of coal
By Andy Winfield

In early November this year, myself and my wife went to the Welsh National Coal Museum also known as the Big Pit. It’s a great visit, looking at the working practices over the years of digging up this material that’s been locked underground since the Carboniferous period. Part of the experience is to go down into the mines, down in the lift, and look at the coal seams. The walls of glittery blackness were shimmering under the light of our head torches. We learned how coal is hard to get to, it requires a lot of ingenuity and effort to get it back to the surface; a surface that it hasn’t seen for many millions of years.

It’s about time they received the attention they deserve; they’re one of the plant world’s many success stories, settling comfortably in the harshest environments with ingenious adaptations. (more…)
