Canada’s toxic chemical valley (2 videos)

The first thing you notice about Sarnia, Ontario, is the smell: a potent mix of gasoline, melting asphalt, and the occasional trace of rotten egg. Sarnia is home to more than 60 refineries and chemical plants that produce gasoline, synthetic rubbers, and other materials that the world’s industries require to create the commercial products we know and love.

The heart works fully but beats at only half the speed of a full human heart — as well as obviously being too small. However, the breakthrough is the latest in a long line of developments which could revolutionise organ transplants.
