If we want to prevent both climate and ecological catastrophes, the key task is to minimise the amount of land we use to feed ourselves, while changing the way the remaining land is farmed. Instead, governments almost everywhere pour public money into planetary destruction.

I saw for the first time the earth's shape. I could easily see the shores of continents, islands, great rivers, folds of the terrain, large bodies of water. The horizon is dark blue, smoothly turning to black. . . the feelings which filled me I can express with one word-joy.

Both the United States and the world economy have already reached - and surpassed - their sustainable physical limits. Ground water is being drawn down, soils eroded, forests cut faster than they grow, fish caught faster than they reproduce, non-renewable fossil fuels burnt without developing substitutes.

The earth is like a beautiful bride who needs no manmade jewels to heighten her loveliness.

Agriculture is at the same time the most tranquil, healthy, and independent occupation.

Here is a little forest Whose leaf is ever green; Here is a brighter garden, Where not a frost has been; In its unfading flowers I hear the bright bee hum; Prithee, my brother, Into my garden come!
