it's because with non organic farming no organic matter is ever
added to soil to help lock everything in... so the nitrates (chemicals) just get leached out into the creeks and on to the rivers. then you either get a direct kill or an algae bloom that starves them (the fish) of oxygen.
the united states has come a long way in returning to organic methods
and in raising the "value" of organically raised food... and now all the major super markets are jumping on the bandwagon
finally because consumers
are demanding that they carry organically raised food more and more.
the problem is....that to be able to declare and sell food that has been "raised organically" you have to do so much paper work and list every single step you take, proceedurally,it's like its a presidential autopsy so that it's definately not worth the hassle . So in esence the government has over regulated the organic growers to
DEATH.
Say for example i am walking in a tomatoe field and see
one plant that could use a boost of compost tea or a single shovel full of
compost. well ..you have to list the source...where you got it...
(whats in it) exactly how much was applied (weight or volume) ,on what day ...what time... and on it goes

and the list is enormous!!!!!
it's totally mental... so then you have farms (farmers) saying that they use "natural methods" but trying to claim organic......forget about it....
it definately pisses me right off.... friggan morons...they ruin everything in the name of special interests and big business.
