Thank you Homer for your answer which explained the ecological disaster meatindustry is causing , but what about fish and eggs? Most often in these discussions we refer to gigantic enterprises and corporations, but what about the "old way" of small scale foodproduction? A man fishing type of thing.

Just another tiny sample of available material:
http://www.factoryfarming.com/eggs.htm”With a growing supply of broiler chickens keeping slaughterhouses busy, egg producers have had to find new ways to dispose of spent hens. One entrepreneur has developed the 'Jet-Pro' system to turn spent hens into animal feed. As described in Feedstuffs, "Company trucks would enter layer operations, pick up the birds, and grind them up, on site, in a portable grinder... it (the ground up hens) would go to Jet-Pro's new extruder-texturizer, the 'Pellet Pro.'"
In one notorious case of extraordinary cruelty at Ward Egg Ranch in February 2003 in San Diego County, California, more than 15,000 spent laying hens were tossed alive into a wood-chipping machine to dispose of them. Despite tremendous outcry from a horrified public, the district attorney declined to prosecute the owners of the egg farm, calling the use of a wood-chipper to kill hens a "common industry practice."
http://www.animalaid.org.uk/farming/shell.htm“Farming hens for their eggs is a huge waste of resources. It takes 3 kilos of grain (in the form of chicken feed) to produce one kilo of eggs. This is because the conversion of crops by farm animals into food for humans is grossly inefficient. And it is not only food (grain) that is wasted. Each battery egg takes approximately 180 litres of water to produce. This is a shocking statistic considering the volumes of water human beings use in developing countries: in India, for example, the poorest people use an average of only 10 litres of water each per day (O'Brien, 1998).
Studies of farm animal housing have shown that egg farms have one of the highest farm emission rates of ammonia gas, a serious environmental pollutant linked to acid rain. “
http://seawifs.gsfc.nasa.gov/OCEAN_PLANET/...il_fishing.html"In many places, heavy fishing pressure and environmental problems have forced governments to limit or halt fishing until fish populations can recover. Overfishing transforms marine ecosystems and also costs people jobs and income §."
http://www.factoryfarming.com/fish.htm“For millennia, fish have been taken from the world's oceans, lakes, and rivers and killed by humans for food. In recent decades, consumer demand for seafood has increased in the U.S., while new technologies have improved our ability to find and catch fish. Over the latter half of the 20th century, wild catches have increased by approximately 500% to nearly 100 million tons per year.
As a result, wild fish populations have been decimated. In addition to fish who are caught by factory trawling vessels, other — economically useless — sea life are caught and killed in the nets. Called 'by-catch,' these animals — including non-target fish, sea turtles, sea lions, and even dolphins — are thrown back into the water dead or dying. The U.S. government estimates more than 100, 000 marine mammals are killed every year by the U.S. commercial fishing industry, and worldwide, it is thought that approximately one third of wild-caught fish are considered 'by-catch.'”
For the guy out fishing for fun:
http://www.health.state.mn.us/divs/eh/fish/faq.html“In Minnesota, mercury is the contaminant in fish that causes the most concern. Air pollution is the major source of mercury that contaminates the fish in Minnesota’s lakes and rivers (see Sources of Mercury Pollution and the Methylmercury Contamination of Fish in Minnesota Attention: Non-MDH link). About 70 percent of the mercury in the air is the result of emissions from coal combustion, mining, incineration of mercury-containing products and other human sources. Over time, fish can accumulate relatively high mercury concentrations. That’s why it’s important to make wise choices about the fish you eat and how often you eat it.
Fish in Lake Superior and major Rivers such as the Mississippi River contain PCBs. These synthetic oils had many uses and are found in electrical transformers, cutting oils, and carbonless paper. Although they were banned in 1976, they do not decompose easily and remain in the water and lake sediments for years. PCB levels in Minnesota waters are slowly decreasing.
Residues of toxaphene in lake trout from Lake Superior suggest a potential environmental health problem with this insecticide. Toxaphene, actually a mixture of over 670 chemicals, was banned in 1990, but continues to be a problem in certain areas. The Minnesota Department of Health continues to monitor reports, and will issue consumption advice based on toxaphene, if necessary.
Dioxins are inadvertently produced through a number of human activities as well as by natural processes. Results to date from an ongoing US EPA study of contaminants in fish from lakes across the US indicate that dioxins are found in every fish tested. The levels of dioxins in the fish tested from Minnesota as part of this study are low overall and low in comparison to other areas of the country. Dioxins accumulate in animal fat and are therefore also present in meat and dairy products. At this time MDH does not provide advice to limit fish consumption based on dioxins in fish. Lakes and rivers where fish have been tested for dioxins and where the levels of dioxins that were measured appear higher than typically found in Minnesota are marked in the site-specific consumption advice tables. “

“As far as anyone knows right now, you probably cannot get sick from eating just a few of
the local contaminated fish. Experts in this field think the real risk is from regularly
eating the local contaminated fish over a long period of time. Results of animal studies
and accidental poisonings of people indicate DDTs and PCBs may cause increased risk of
cancer and developmental problems in babies and children.”
