Fossil Fuels

Eggs and Fossil Fuel Usage

Many people try to buy local food to reduce fossil fuel usage by reducing "food miles," the distance food has to travel to get from farm to plate. A famous 2008 study from Carnagie Mellon University found that a single day without any animal products, including eggs, has more of an impact on decreasing fossil fuel usage than eating just locally sourced food every day of the week.

Egg waste

Eggs and Water Usage

It takes at least five times as much water to produce an egg as it takes to produce a potato for roughly the same amount of calories. A potato even has slightly more protein than the egg! As an added benefit, the water that goes into producing potatos does not result in any water pollution.

Eggs come from female chickens (just like cows' milk comes from female cows). This is "feminized protein" or protein from the reproductive systems of female animals. You have to ask yourself, "What happens to all the male chicks?" They have no commercial value and don't grow into animals that are used for food. The 50% of hatched animals who are male are destroyed in horrible ways; sometimes, their powdered remains are fed to other herbivore animals.

Egg Eggs and greenhouse gases

Eggs and Greenhouse Gases

Many people eat eggs because they think eggs are a good source of protein. However, few people know the cost of that protein in terms of fossil fuel. The U.N. reported in 2006 that producing one calorie of animal protein takes ten times the amount of fossil fuel as one calorie of plant protein. Ten times the amount of fossil fuel! Animal protein also produces ten times the amount of carbon dioxide, a greenhouse gas. If you are looking for protein, you would be better off eating a potato than an egg. Surprisingly, a potato has slightly more protein than an egg ... many people have lived healthfully their entire lives on just the simple potato.

Michael Gregor, MD, produces many videos on many nutriton topics. He often exposes sham science, research in medical journals supported by industry dollars. One recent video clearly explained how eating eggs have a big effect on raising blood cholesterol levels after a meal - when most heart attacks occur. Here is what he said:

The cholesterol in eggs not only worsens the effects of saturated fat, but has a dramatic effect on the level of cholesterol and fat circulating in our bloodstream during the day.

Doctors are so used to testing fasting cholesterol levels to monitor the effects of drugs, they too often fall for those egg industry tactics hook, line, and sinker.

Egg Eggs and water pollution

Eggs and Water Pollution

Why does it take so much water to produce animal foods, including eggs? According to, animals drink only about 1% of the water used. The remaining 99% of the water used is to grow feed for the animals to eat - a water-intensive way of getting anmial flesh and secretions such as eggs.

Of course, all that feed is processed by the animals and then excreted. Who do you think produces more waste products in the United States: all the people who live here or all the animals and their secretions used for food? Surprisingly, the animals used for food produce 130 times the amount of waste as people (this statistic is from WorldWatch Institute and the World Health Organization). There are strict regulations on how human waste is processed, which is one of the major reasons so many deadly diseases are a thing of the past. However, animal waste does not have all those regulations and most ends up in fresh water supplies, affecting many people's drinking water and killing lakes and streams.

On their website, the Natural Resources Defense Council outlined some of the issues surrounding chicken waste:

  • Runoff of chicken and hog waste from factory farms in Maryland and North Carolina is believed to have contributed to outbreaks of Pfiesteria piscicida, killing millions of fish and causing skin irritation, short-term memory loss and other cognitive problems in local people.

  • Nutrients in animal waste cause algal blooms, which use up oxygen in the water, contributing to a "dead zone" in the Gulf of Mexico where there's not enough oxygen to support aquatic life. The dead zone fluctuates in size each year, extending a record 8,500 square miles during the summer of 2002 and stretching over 7,700 square miles during the summer of 2010.

  • Ammonia, a toxic form of nitrogen released in gas form during waste disposal, can be carried more than 300 miles through the air before being dumped back onto the ground or into the water, where it causes algal blooms and fish kills.

Egg Egg

Eggs and Kindness

Occasionally, some folks can chickens running free on an open field, happily being chickens and doing chicken things such as scratching for food, flapping and spreading their wings, taking dust baths to remove debris and insects from their feathers, and bonding with their young and other members of their flock. Female chickens lay eggs in nests. We like to think that these are the chickens providing the eggs that we eat for breakfast. We think, "No harm comes to the chickens who lay our eggs, so why not eat eggs?" However, it is a myth that we treat chickens well and the reality is disturbing. Here are some facts from the 2013 book "Meatonomics" by David Robinson Simon:

  • Egg produces kill 270 million unwanted male chicks each year, enough tiny dead birds to circle the contiguous United States [p. 218].

  • For chickens unlucky enought to be born female and destined for a laying career, life starts with a painful procedure known clinically as "partial beak amputation." ... This procedure involves cutting off about one-third of an unanesthetized chick's beak and leaving the sensitive nerve endings exposed for the remainder of her life ... There is no human analog to debeaking, though it's not much off a stretch to compare it to having your lips cut off and cauterized [p. 218].

  • [A] battery cage is used to house house laying hens ... To get an idea of the conditions of a typical battery cage, imagine ten birds living in the drawer of a filing cabinet.

  • Of course, the dropping have to go somewhere, which is why the cages have wire mesh floors (note the dropping go on the bodies of the birds below before reaching the bottom) ... Standing on these surfaces for their whole existence, birds often develop painful joing conditions, brittle bones, and crippling deformities. By the end of their lives, 30 percent of laying hens are likely to have broken bones [p. 221].

  • Wild hens typically lay about twenty eggs per year. By contrast, hens in US factory farms laid an average of 269 eggs in 2010, slightly more than needed to satify a typical American's annual consumption of 246 eggs. This thirteenfold productivity increase in egg factories is driven by innovations such as forced molting, the practice of starving hens for up to two weeks to increase productivity [p. 221-222].

  • The American Egg Board estimates that 5 percent of eggs consumes in 2010 were cage-free, a number that grows as consumers are egged on to buy the output of "humanely" raised hens ... In fact, most cage-free hens are raised in industrial environments identical in almost all repects to battery cage facilities. Thus, like battery hens, cage-free hens are typically rasied in dark steel-and-concrete warehouses reeking of ammonia and other fumes [p. 223].

  • The term "free-range" refers to eggs from hens with access to the outdoors. However, few birds take advantage of the ability to go outside ... As noted, Michael Pollan observed during his visits to free-range chicken famrs, he never actually saw a chicken go outside [p. 224].

  • Many believe, with good reason, that so-called humane farming measures do little to protect animals, and they'd rather see the abolition, not the amelioration, of the cruel practices found in factory farms ... when implemented by industrial methods, even farming practices laveled organic, cage-free, and free-range are routinely little better for animals than the more blatantly inhumane alternatives.
