Greenhouse Farming Quotes

An image suddenly loomed in his mind: the greenhouse effect. Yes. The Earth is a gigantic greenhouse. With us planted here millions of years ago by aliens. Soon they’ll be back for the harvest.

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.

This is always always always what she wished a bazaar to be. Demre, proudly claiming to be the birthplace of Santa Claus, was direly lacking in workshops of wonder. Small corner stores, an understocked chain supermarket on the permanent edge of bankruptcy and a huge cash and carry that serviced the farms and the hotels squeezed between the plastic sky and the shingle shore. Russians flew there by the charter load to sun themselves and get wrecked on drink. Drip irrigation equipment and imported vodka, a typical Demre combination. But Istanbul; Istanbul was the magic. Away from home, free from the humid claustrophobia of the greenhouses, hectare after hectare after hectare; a speck of dust in the biggest city in Europe, anonymous yet freed by that anonymity to be foolish, to be frivolous and fabulous, to live fantasies. The Grand Bazaar! This was a name of wonder. This was hectare upon hectare of Cathay silk and Tashkent carpets, bolts of damask and muslin, brass and silver and gold and rare spices that would send the air heady. It was merchants and traders and caravan masters; the cornucopia where the Silk Road finally set down its cargoes. The Grand Bazaar of Istanbul was shit and sharks. Overpriced stuff for tourists, shoddy and glittery. Buy buy buy. The Egyptian Market was no different. In that season she went to every old bazaar in Sultanahmet and Beyoğlu. The magic wasn’t there.

Yet a third of the food raised or prepared does not make it from farm or factory to fork. That number is startling, especially when paired with this one: Hunger is a condition of life for nearly 800 million people worldwide. And this one: The food we waste contributes 4.4 gigatons of carbon dioxide equivalent into the atmosphere each year—roughly 8 percent of total anthropogenic greenhouse gas emissions.

Organic farming is environmentally friendlier to every acre of land. But it requires _more_ acres. The trade-off is a harsh one. Would we rather have pesticides on farmland and nitrogen runoffs from them? Or would we rather chop down more forest? How much more forest would we have to chop down? If we wanted to reduce pesticide use and nitrogen runoff by turning all of the world’s farmland to organic farming, we’d need about 50 percent more farmland than we have today. Nobel Prize winner Norman Borlaug, whose work helped triple crop yields over the last fifty years and arguably saved billions from starvation, estimates that the world would need an _additional_ 5 to 6 billion head of cattle to produce enough manure to fertilize that farmland. There are only an estimated 1.3 billion cattle on the planet today. Combined, we’d need to chop down roughly half of the world’s remaining forest to grow crops and to graze cattle that produce enough manure to fertilize those crops. Clearing that much land would produce around 500 billion tons of CO2, or almost as much as the total cumulative CO2 emissions of the world thus far. And the cattle needed to fertilize that land would produce far _more_ greenhouse gases, in the form of methane, than all of agriculture does today, possibly enough to equal all human greenhouse gases emitted from all sources today. That’s not a viable path.

The Herb Farm reminded Marguerite of the farms in France; it was like a farm in a child's picture book. There was a white wooden fence that penned in sheep and goats, a chicken coop where a dozen warm eggs cost a dollar, a red barn for the two bay horses, and a greenhouse. Half of the greenhouse did what greenhouses do, while the other half had been fashioned into very primitive retail space. The vegetables were sold from wooden crates, all of them grown organically, before such a process even had a name- corn, tomatoes, lettuces, seventeen kinds of herbs, squash, zucchini, carrots with the bushy tops left on, spring onions, radishes, cucumbers, peppers, strawberries for two short weeks in June, pumpkins after the fifteenth of September. There was chèvre made on the premises from the milk of the goats; there was fresh butter. And when Marguerite showed up for the first time in the summer of 1975 there was a ten-year-old boy who had been given the undignified job of cutting zinnias, snapdragons, and bachelor buttons and gathering them into attractive-looking bunches.

ethanol may actually make some kinds of air pollution worse. It evaporates faster than pure gasoline, contributing to ozone problems in hot temperatures. A 2006 study published in the Proceedings of the National Academy of Sciences concluded that ethanol does reduce greenhouse gas emissions by 12 percent relative to gasoline, but it calculated that devoting the entire U.S. corn crop to make ethanol would replace only a small fraction of American gasoline consumption. Corn farming also contributes to environmental degradation due to runoff from fertilizer and pesticides. But to dwell on the science is to miss the point. As the New York Times noted in the throes of the 2000 presidential race, ―Regardless of whether ethanol is a great fuel for cars, it certainly works wonders in Iowa campaigns. The ethanol tax subsidy increases the demand for corn, which puts money in farmers‘ pockets. Just before the Iowa caucuses, corn farmer Marvin Flier told the Times, ―Sometimes I think [the candidates] just come out and pander to us, he said. Then he added, ―Of course, that may not be the worst thing. The National Corn Growers Association figures that the ethanol program increases the demand for corn, which adds 30 cents to the price of every bushel sold. Bill Bradley opposed the ethanol subsidy during his three terms as a senator from New Jersey (not a big corn-growing state). Indeed, some of his most important accomplishments as a senator involved purging the tax code of subsidies and loopholes that collectively do more harm than good. But when Bill Bradley arrived in Iowa as a Democratic presidential candidate back in 1992, he ―spoke to some farmers‖ and suddenly found it in his heart to support tax breaks for ethanol. In short, he realized that ethanol is crucial to Iowa voters, and Iowa is crucial to the presidential race.

Whereas CO2 is the dominant greenhouse gas overall, it accounts for only 11 percent of agricultural emissions.2 The rest is nitrous oxide (53 percent) and methane (36 percent). Nitrous oxide is 296 times more potent per pound than CO2 as a climate-change gas, and on farms it results mainly from the use of fertilizer but also from cattle pee, especially if there is excessive protein in their diet, and from the burning of biomass and fuel.3 Methane, which is 25 times more potent than CO2, is mainly emitted by cows and sheep when they belch. Some is also emitted from silage. The CO2 comes from machinery but also from the heating of greenhouses to grow crops out of season or in countries that just don’t have the right climate.

One common strategy on which we should all be able to agree is to take steps to reduce the risk of human extinction when those steps are also highly effective in benefiting existing sentient beings. For example, eliminating or decreasing the consumption of animal products will benefit animals, reduce greenhouse gas emissions, and lessen the chances of a pandemic resulting from a virus evolving among the animals crowded into today’s factory farms, which are an ideal breeding ground for viruses. That therefore looks like a high-priority strategy. Other

It magnifies your carbon footprint. If you cut back your animal food intake, you can make a big impact on planet Earth. Each year we eat billions of pounds of meat and drink billions of gallons of dairy products from billions of animals. In doing so, we not only contribute to inhumane animal practices, but we are responsible for the use of large amounts of chemical pesticides and fertilizers to produce animal feed, as well as large volumes of water and fuel to take animals to market. Byproducts of animal food production include greenhouse gas emissions, toxic manure lagoons, deforestation, and pollution of groundwater, rivers, streams, and oceans. According to a recent analysis conducted by CleanMetrics for the Environmental Working Group, greenhouse gas emissions generated by conventionally raising lamb, beef, cheese, pork, and farmed salmon—from growing the animals’ food to disposing of the unused food—far exceed those from other food choices like lentils and beans.26

With the advent of controlled-environment agriculture it had become nearly impossible for individual farm families to compete economically with the mass-production greenhouses, so in most of the United States it was relatively easy for a young couple to purchase an old farm property and cultivate the soil, not for cash crops, but simply to live independently.

For example, if the sixteen million acres now being used to grow corn to feed cows in the United States became well-managed pasture, that would remove fourteen billion pounds of carbon from the atmosphere each year, the equivalent of taking four million cars off the road. We seldom focus on farming’s role in global warming, but as much as a third of all the greenhouse gases that human activity has added to the atmosphere can be attributed to the saw and the plow.

There are other downsides to synthetic fertilizer. To make it, we have to produce ammonia, a process that requires heat, which we get by burning natural gas, which produces greenhouse gases. Then, to move it from the facility where it’s made to the warehouse where it’s stored (like the place I visited in Tanzania) and eventually the farm where it’s used, we load it on trucks that are powered by gasoline. Finally, after the fertilizer is applied to soil, much of the nitrogen that it contains never gets absorbed by the plant. In fact, worldwide, crops take up less than half the nitrogen applied to farm fields. The rest runs off into ground or surface waters, causing pollution, or escapes into the air in the form of nitrous oxide—which, you may recall, has 265 times the global-warming potential of carbon dioxide.

If the world’s 1 billion cows were a country, they’d rank third in greenhouse gases after China and the United States. Accounting for nearly two thirds of total livestock emissions, beef and dairy cattle dwarf the climate threat from all other farm animals combined, including pigs, chickens, lambs, goats, and ducks.

In the 1990 election campaign both Labour and National parties adopted ambitious targets to reduce greenhouse gas emissions. The country at that point was near carbon-neutral, with sources of emissions balanced by forestry which s3equestered the carbon. However, in the coming decade emissions would skyrocket as New Zealanders drove more; trucks replaced rail and shipping for freight; coal and gas were increasingly burnt for electricity; vast swathes of the country’s farms and wetlands were converted to dairy farming; and coal was used to convert that milk to powder for export. The National government spent the 1990s anguishing over what tool to use to reduce emissions and ended up doing nothing. Labour came in in 1999, signed up to the Kyoto Protocol and announced a carbon tax, but set it so far in the future that coalition politics eventually killed it. Meanwhile, every year, NZ’s net emissions increased from cars, cows and coal. Labour took climate pollution out of the RMA, relying on voluntary commitments and technological wishes… By 2008 NZ’s emissions were 25% higher than they had been in 1990.

2050, milk consumption in China is expected to grow to triple the current level, thanks to the changing, West-facing tastes of its emerging consumer classes, a single-item boom in a single country that is expected, all by itself, to increase global greenhouse-gas emissions from dairy farming by about 35 percent.

Canadian team created the Enviropig, an environmentally friendly transgenic pig containing an E. coli gene that allowed the animals to better digest a phosphorus-containing compound called phytate. Normal pig manure retains high phosphorus levels that leach into streams and rivers, causing algal blooms, the death of aquatic animals, and the production of greenhouse gases; Enviropig manure contained 75 percent less phosphorus, which could have been an enormous benefit to the planet and to the people who lived and worked near pig farms. Despite this, though, and despite reassuring safety data, consumers decried the Enviropig, causing the project’s financial backers to pull the plug.
