We all live on the same planet, it is our only home, so... we used to rotate crops back in the day and, you know, who cares if you're going to make a profit if everybody's too dead or glowing in the dark to be able to purchase anything.

The history of agriculture is the history of humans breeding seeds and animals to produce traits we want in our crops and livestock.

In the seventeenth century, the science of medicine had not wholly cut asunder from astrology and necromancy; and the trusting Christian still believed in some occult influences, chiefly planetary, which governed not only his crops but his health and life.

Those who profess to favor freedom, and yet deprecate agitation, are men who want crops without plowing up the ground.

All the food we eat - every grain of rice and kernel of corn - has been genetically modified. None of it was here before mankind learned to cultivate crops. The question isn't whether our food has been modified, but how.

Some bioengineering is good, especially if it results in plants that are more drought-resistant or perennial food crops.

I am proud to have been born in Iowa. Through the eyes of a ten-year-old boy, it was a place of adventure and daily discoveries - the wonder of the growing crops, the excitements of the harvest, the journeys to the woods for nuts and hunting, the joys of snowy winters, the comfort of the family fireside, of good food and tender care.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

We could never have loved the earth so well if we had had no childhood in it, if it were not the earth where the same flowers come up again every spring that we used to gather with our tiny fingers as we sat lisping to ourselves on the grass, the same hips and haws on the autumn hedgerows, the same redbreasts that we used to call 'God's birds' because they did no harm to the precious crops. What novelty is worth that sweet monotony where everything is known and loved because it is known?

We can grow crops less expensively because molecular manufacturing technology is inherently low cost.

Technology has allowed us to have more drought-resistant crops. The spotty nature of drought the spotty nature of rains can sometimes result in better yields than anticipated.

That's not all our crops can do. We are also learning how to transform plants into factories. We can now raise plants that will create enzymes that would otherwise be created in chemical factories.

It's the opinion of some that crops could be grown on the moon which raises the fear that it may not be long before we're paying somebody not to.
