My grandmother was energetic and fearless - a talented poet and songwriter. She was also interested in chemistry and history and medicine, taking care of the people in her hacienda in Mexico, delivering babies. She could have become anything, but this was the 1930s, and she was forced into an arranged marriage.

But dolphins, which fill the oceans with blipping and chirping, and whales, which mew and caw in ultramarine jazz - a true rhapsody in blue - are hunted to the edge of silence.
