Over 50% of US Food Supply Now PETROLEUM Based.

This all went out the window after world war two and some German scientist, his country short of natural nitrogen during the war for the German manufacture of bombs, found a way to make nitrogen out of PETROLEUM. The U.S. war time munitions industry turning out millions of tons of nitrogen for bombs during the war from petroleum, losing that market, had to find a new customer after the war, and turned to the American farmer.

The amount of crops 'til then, that any farm produced were limited mainly by the amount of "complete" natural fertilizer the farmer could recycle back into his farm land.

Sort of like a fertilizer on steroids.

Now we cultivated and hoed and used every trick in the book to keep weeds from overtaking our crops and stealing what natural nitrogen existed from our cultivated plants.

After the second world war, these same people developed herbicides, made from petroleum that could poison the weeds and they had to develop crop plants that could withstand the plant poison.

Instead of killing the offending weeds the old hand method, now they went to mass spraying, and used this petroleum based herbicide to poison plant life in general.

We lost, each year, a percentage of our crop to root worms etc and varied insects that got a big foot hold some years and cut into our crop.

After the war, they came out with extensive pesticides petroleum- (oil) based, chemical insect and worm killers and sprayed this new poison over the fields heavily, thereby killing all natural worms and insects that in nature turn plant fiber back into nutrients.

All this has happened with the crops. (Plants)
