Dr. Tilman of Minnesota notes that farming has already produced the biggest global imprint of humanity, affecting half the earth's habitable land.

Peasants often abandoned farming to produce steel or work in other industrial production.

In 1986 farming produced $600 million in cash receipts, which increased to $650 million in 1990 and $706.2 million last year.

And naturally they must downplay the many waves of radicalism that farming has produced over the years.

That, however, never realised since the line's farming produce traffic was gradually lost to road transport on the improving road network, a decline that eventually led to the ACR's demise.

He then controlled their fields and collected their farming produce for himself.

Scientists and economists also said that as soil in regions of cleared forest has become fragile after short periods of use, farming has not produced the levels of economic success originally expected.

Most of the soil is stony and barren, so conventional farming produces little reward.

Unlike traditional farming in non-tropical areas, indoor farming can produce crops year-round.

Irrigated farming in the basin produces sugar beets, onions, potatoes, corn, mint, grain, alfalfa seed, vegetable seed, and hay.
