This is getting weird.

You obviously misread what I wrote. My post was directed at the animal death cost of producing 1kg of useable protein from beef as opposed to from soybean. I never mentioned water pollution and only mentioned habitat alteration on terms of monoculture production. My comment was entirely based on the number of lives lost.
As presented the table is completely meaningless simply because there are no units anywhere. I’d have to see where those figures were collected and what they are based on. Is it per/ha or total world area? Is the habitat alteration figure per/ha or in terms of net loss of biodiversity. Do they really refer to crude protein production? I can see one glaring fault with them. I’m currently undertaking a M.Sc. on the greenhouse contribution of the grazing industry, and far from being a greenhouse emitter grazing is in fact a net greenhouse sink. I can provide you with any number of references for that if you like. Feeding animals does not and has not required habitat to be cleared over the greater part of the worlds surface area, and even if it did my point was that it never produces anything close to a monoculture.

**I do not understand why eating plants only is more wasteful to animal life than eating animals and plants. When you eat an animal, that animal has to be fed plants, A LOT of plants, to produce a small amount of food (meat) for you to eat. So when you eat animals, you eat the animal, and (in a sense) all the plants it was fed throughout its lifetime. **
Again you haven’t understand what has been written. Humans need protein. Cattle and sheep can be grazed on land that has not been converted to a monoculture, and still continues to support spiders, prairie dogs, birds etc. This is never the case with bean farms,
Now for the references. According to Burrows, Orr, Back and Anderson (Proceedings 36th Annual Rangelands Congress) to produce one steer I require 2 hectares of native pasture on poor soils and moderate rainfall. On areas capable of sustaining cropping this figure can readily be tripled but I’ll ignore that. This will produce 40kg of protein/year. Soy will yield 415 kg of bean/ha on average according to USDA figures, and on far better land with irrigation and fertiliser. Allowing an upper estimate of 44% protein the figure comes out at 182.6 kg protein/ha. Now to achieve these yields we have, courtesy of the Qld Dpt. Of Primary Industries FactSheets the following deliberate deaths for soybean based on a 1ha plot with 90 cm spacing and 20 cm between plants:
Recommended density when treatment occurs:
Heliothis = 20000 deaths
Green Vegetable Bug 33333 deaths
bean fly = 50000 deaths
I won’t include nematodes here because there are no figures I could find on their numbers. It would be in the millions. I also won’t include the figures for the other 6 insect pests common on soy beans in this are of the world which the recommended spray threshold is 1-3/square metre.
Of course one spraying even for locusts could easily double this figure. This also doesn’t include the non-target species like bees and spiders, or the incidental deaths from habitat destruction (eg the burrowing mammals.) or the need to kill the stored goods pests like moths, borers, weevils mice and rats that aren’t an issue with meat protein. Having discounted those we have:
total of 103333 needless deaths or 566/kg protein produced/death.
Compared with the maximum sustainable parasite loads in cattle of:
45 ticks per animal
1000 buffalo flies/animal
I won’t include nematode here either
Total of 1046 meaningless deaths or 26.15/kg protein/death
Therefore utilising plant protein results in the deliberate deaths of more animals than the utilisation of animal. Saying you eat plant protein to minimise the number of animals killed makes no sense, even if you do get to sleep better at night because you can say you didn’t do it yourself. To sensibly save animal lives you should get as much of your protein as possible from animal sources and reserve the more ‘lethal’ plant foods for carbohydrate sources, where they do become more environmentaly friendly.

**Please provide a reputable cite that proves that vegetarians are responsible for more animal death than meat-eaters. Bear in mind, unless a meat-eater eats NO veggies, they are also responsible for the death of the bugs and other critters that die during plant farming. So I don’t see your logic here. **
That is because you apparently fail to understand that humans cannot subsist on carbohydrate alone. Utilising plant protein is excessively wasteful of animal life as I demonstrated above. By all means utilise plants as a carbohydrate source and you may break even in terms of deaths/kilojoule, but try to utilise plants as a protein source and you’re fighting a losing battle. Add to this the fact that cropland requires the complete destruction of all aboveground life every 12 months at least, compared to the majority of free range grazing which occurs on natural pastures and you become an absolute mass murderer by utilising plants as a protein source. There was actually a very good paper published in ‘Nature’ on this a few years go, but unfortunately my only copy is at work and I’m now on holidays. I hope the cites above will satisfy you for the next few weeks.
**I can’t get a cite right now, but I know I’ve read many places that the cost of producing a pound of meat vs. a pound of grian for human consumption is amazing. The amount of water and land and pesticide and pollution and general mayhem produced by meat production is just astronomical. I have big problems with this. **
Your sources were almost right. It does require more energy to produce a kilojoule of energy from beef than from grain. The amount of pesticide used is actually a lot less. Of course you should remember that grazing often occurs on land where cropping is quite simply impossible and so this is the only effective way to get food off the land. Grazing is also far more environmentaly friendly. And of course as I demonstrated above there is far less loss of life involved in producing protein from animals than from plants.

Are you saying that eating meat and plants is less detrimental to the world or ecology overall, compared to JUST eating plants? And, what are you trying to say about vegetarians? What do you presume about the reasons or motivations behind vegetarianism?
