Probably the letter writing chappie rather fancied the idea of contributing to the disposal of the oysters' insides. Is it not true that when the earth was young and had a lot of CO2 and all was happy because humans had not appeared, biomass used up a lot of it (oil) and shellfish also (limestone). Since we are undoing the one mechanism (trees ->oil) it makes sense to fix it by helping the other one along. But is there enough calcium? Dick Jackson
