There are many environmental benefits to organic methods including reduced use of herbicides and pesticides such as neonicotinoids which are implicated in the decline of bee numbers. Another benefit is the greater diversity of vegetable varieties also associated with organic farming. This is for two reasons: to use varieties with greater natural resistance to pests and to use more flavoursome varieties to differentiate from non-organic produce. A recent study of studies of yield from organic methods compared with so-called conventional methods has recently been published in Nature and reported here by the BBC. From the BBC report: The headline conclusion is pretty unequivocal; across the board, organic farming produces lower yields than conventional methods, by about 25%. For fruit, the difference is marginal, just a few percen...
