ᅠᅠThe chart is displayed on a large screen while the audience at a forum comparing farming methods listens to several speakers.

ᅠᅠThe notes used by two of the speakers at the forum are provided on the accompanying tabs.

• Producing a liter of milk from cows organically requires 80 percent more land, releases 60 percent more undesirable nutrients from manure into water sources, and contributes 70 percent more to acid rain than does producing milk nonorganically.
• Raising potatoes organically uses more energy for needed tilling and plowing than does raising them nonorganically, and a hectare of nonorganically farmed land produces 2.5 times more potatoes than does organically farmed land.
• Organic farmers often treat fungal diseases with copper pesticide solutions that, unlike today's biodegradable chemical pesticides, can stay toxic in soil for decades.
• Studies found a bacterium harmful to humans in 100 percent of organic chicken flocks but only 33 percent of other chicken flocks.

• Organic farms avoid the application of industrial chemicals, thus minimizing harm to ecosystems, and they produce less extraneous waste (e.g., plastic packing materials for chemicals and feed).
• Organically farmed apple orchards are, on average, about 7 percent more energy efficient than nonorganically farmed orchards.
• Organically fertilized soils release less nitrous oxide (a cause of acid rain) than do chemically fertilized soils.
• There is no evidence that organic farms release, on average, more undesirable nutrients into water sources than do nonorganic farms.
