Consider this: all the ants on the planet, taken together, have a biomass greater than that of humans. Ants have been incredibly industrious for millions of years. Yet their productiveness nourishes plants, animals, and soil. Human industry has been in full swing for little over a century, yet it has brought about a decline in almost every ecosystem on the planet. Nature doesn't have a design problem. People do. ↗
As far as food is concerned, the great extravagance is not caviar or truffles, but beef, pork and poultry. Some 38 percent of the world's grain crop is now fed to animals, as well as large quantities of soybeans. There are three times as many domestic animals on this planet as there are human beings. The combined weight of the world's 1.28 billion cattle alone exceeds that of the human population. While we look darkly at the number of babies being born in poorer parts of the world, we ignore the over-population of farm animals, to which we ourselves contribute...[t]hat, however, is only part of the damage done by the animals we deliberately breed. The energy intensive factory farming methods of the industrialised nations are responsible for the consumption of huge amounts of fossil fuels. Chemical fertilizers, used to grow the feed crops for cattle in feedlots and pigs and chickens kept indoors in sheds, produce nitrous oxide, another greenhouse gas. Then there is the loss of forests. Everywhere, forest-dwellers, both human and non-human, can be pushed out. Since 1960, 25 percent of the forests of Central America have been cleared for cattle. Once cleared, the poor soils will support grazing for a few years; then the graziers must move on. Shrub takes over the abandoned pasture, but the forest does not return. When the forests are cleared so the cattle can graze, billions of tons of carbon dioxide are released into the atmosphere. Finally, the world's cattle are thought to produce about 20 percent of the methane released into the atmosphere, and methane traps twenty-five times as much heat from the sun as carbon dioxide. Factory farm manure also produces methane because, unlike manured dropped naturally in the fields, it dies not decompose in the presence of oxygen. All of this amounts to a compelling reason...for a plant based diet. ↗
I turn and walk back to the home shore whose tall yellow bluffs still bare of snow I can see nearly half a mile to the north. I find my way as I came, over dusty sandbars and by old channels, through shrubby stands of willows. The cold, late afternoon sun breaks through its cloud cover and streaks the grey sand mixed with snow. As it has fallen steadily in the past weeks, the river has left behind many shallow pools, and these are now roofed with ice. When I am close to the main shore I come upon one of them, not far from the wooded bank. The light snow that fell a few days ago has blown away; the ice is polished and is thick enough to stand on. I can see to the bottom without difficulty, as through heavy dark glass. I bend over, looking at the debris caught there in the clear, black depth of the ice: I see a few small sticks, and many leaves. There are alder leaves, roughly toothed and still half green; the more delicate birch leaves and aspen leaves, the big, smooth poplar leaves, and narrow leaves from the willows. They are massed or scattered, as they fell quietly or as the wind blew them into the freezing water. Some of them are still fresh in color, glowing yellow and orange; others are mottled with grey and brown. A few older leaves lie sunken and black on the silty bottom. Here and there a pebble of quartz is gleaming. But nothing moves there. It is a still, cold world, something like night, with its own fixed planets and stars. ↗
Old-time ranchers planted cheatgrass because it would green up fast in the spring and provide early forage for grazing cattle,” Oyster says, nodding his head at the world outside. This first patch of cheatgrass was in southern British Columbia, Canada, in 1889. But fire spreads it. Every year, it dries to gunpowder, and now land that used to burn every ten years, it burns every year. And the cheatgrass recovers fast. Cheatgrass loves fire. But the native plants, the sagebrush and desert phlox, they don’t. And every year it burns, there’s more cheatgrass and less anything else. And the deer and antelope that depended on those other plants are gone now. So are the rabbits. So are the hawks and owls that ate the rabbits. The mice starve, so the snakes that ate the mice starve. Today, cheatgrass dominates the inland deserts from Canada to Nevada, covering an area over twice the size of the state of Nebraska and spreading by thousands of acres per year. The big irony is, even cattle hate cheatgrass, Oyster says. So the cows, they eat the rare native bunch grasses. What’s left of them... “When you think about it from a native plant perspective,” Oyster says, “Johnny Appleseed was a fucking biological terrorist.” Johnny Appleseed, he says, might as well be handing out smallpox. ↗
A college football star, by his senior year, is used to running out there with 110,000 people going nuts. They feel comfortable in that environment. To me, a set feels like that. The one thing that I do know is that, as long as I'm prepared, I know this environment and this world. ↗
