Real life has caught up big time this week and I have an assignment to complete in the next couple of days, I am really busy also my elderly neighbour has also become increasingly needy and confused and I can't abandon her but she really soaks up the time. So sadly, I haven't time to write (except bloody carbon cycle and not carbon fibre, and grassland ecology) and most of that is calculations in gC per m squared per year.

Anyone who thinks the Open University is a soft option is probably too stupid to do a degree with them.
