Not sure what exactly I'm replying to, because I do believe seeking mutually beneficial outcomes is a good thing. The way that 'mutually' is achieved or generated is the problematic aspect in my view.

I've been wondering, what was scary about seeking mutually beneficial outcomes gabby? Seems I'm a master at the failed followup. :p

We have large scale versions in the UK - the muck is treated and
pathogens removed. It was once called night soil here. Quite what
precautions are taken in India is a bit scary. My point largely
concerns the possibility of a 40% fertiliser reduction and how many
more examples could be drawn into an economic plan. Fishing gear is
being changed to do less damage to the sea bed and reduce the
ludicrous amount of stock dumped at sea because it doesn't match rules
on what can be landed - pilot projects have reduced 'throw back' from
37% to less than one.
