'Meat' the enemy: New food for thought from noted biochemist
July 12, 2010 BY KRISTA CONGER(PhysOrg.com) -- Pat Brown hates animals. On your plate, that is. And he's going to do something about it.
The School of Medicine biochemist is taking a yearlong sabbatical — starting now — to figure out how to get you, me and, yes, even the rest of the world to stop bolting down hamburgers, chicken and ribs, and turn instead to beans, carrots and avocados. Why? The environmental cost of meat is just too high.
“People are sort of in denial about whether this is even an issue,” said Brown, MD, PhD, a professor of biochemistry and a Howard Hughes Medical Institute investigator. “But eating one 4-ounce hamburger is equivalent to leaving your bathroom faucet running 24 hours a day for a week. We can’t go on like this.” (See a 2006 report by the Food and Agriculture Organization of the United Nations for this and other statistics.)
Brown, who is also a member of the Institute of Medicine and the National Academy of Sciences, has been a vegetarian for decades and a vegan for five years. He doesn’t want to outlaw eating animal products, but he does want us to begin paying for their true cost. Cows, for example, excrete methane and nitrous oxide, which contribute to global warming, and gobble down tons of water-sucking grains and plants, exacerbating water shortages worldwide.
“Thirty percent of the world’s land is devoted to animal farming,” said Brown. “People need to begin taking responsibility for their food choices. If they can’t do it voluntarily, then we can use economic incentives.” Incentives that include increasing the price of meat at the supermarket counter so it costs two to three times what you’re paying now.
The attempt to change the world’s eating habits seems quixotic, until you consider Brown’s track record. In the early ’90s, he invented the DNA microarray — a method of scanning the activity levels of tens of thousands of genes simultaneously — that’s since become a workhorse in laboratories around the world. And three years ago he conceived of and launched an entirely new type of scientific journal: one in which every article is publicly available, immediately. The publishing industry scoffed but now the Public Library of Science series of journals is one of the most highly respected in the world.
“Scientists are more inclined to do this sort of thing than most people, because we tend to be almost absurdly optimistic,” said Brown. “We believe that things kind of outside the box may still work.”
As for facing the wrath of the meat lovers? Brown’s not fazed. “I like angry people. If people aren’t angry, I’m not doing my job.”

True, we could all(at least, for the most part, in the developed world) do with a little less(especially)red meat. That's a given.
The problem is not the meat itself, it's the method of producing it. The system is highly inefficient and wasteful- therefore the "24hr faucet" analaogy. Agricultural practices need to be combined wherever possible- crops, forestry, animal husbandry all occurring on the same parcel of land simultaneously. That way, fertilizer, erosion control, and fodder can all be obtained simultaneously, more or less at the same time that crops/fruits/nuts are growing.
Doesn't work everywhere, with every combination of beast and flower, and it is more labor intensive- but it is sustainable, and at far less cost accross the board than what Brown is proposing.

You get most of your daily vital elements from a slab of meat the size of a deck of cards. In order to derive the same nourishment and caloric intake from plants you'd need a more varied diet, more imports and exports as not all required foodstuffs grow everywhere, citrus for example, and you'd require a far large volume intake than you currently receive.
If you want to kill off about a billion people have the whole world go vegan.
Cutting back on our intake is a good thing. Removing meat entirely is madness.

Now I'm not going to go and detract from someone's personal choice. If you choose to have a vegetarian, carnivorous or hybrid diet, that's fine, but don't say we can feed the world by eliminating meat. It's incorrect and mathematically wrong.
Your second point that all the feeds will be available for human consumption is also in error.
How do you think we fertilize all the food stuffs outside of petrochemical fertilizer?

As for Vitamin 12, yes it is more difficult to source solely from plants in today’s supermarkets–It is produced by micro-organisms that are found in the soil and on the surface of plants. However, it's destroyed by pesticides and the stringent hygienic practices of modern agriculture. Therefore it’s not the vegan diet that’s the problem, it’s the agricultural practice.

>>Your second point that all the feeds will be available for human consumption is also in error.
In your last point I see that you’re moving from veganism to sustainability - I believe these are two separate but linked propositions. Let me address both.
If you want to grow things on a massive scale – you need artificial fertilisers. I don’t think this is ideal but this is the reality we live with today. All things equal if you assume that agricultural practices will continue as they are, and include petro-chemical fertilizers, land use is far more efficiently put towards growing plants that are available for people rather than for animals. I’m not saying you could feed the world, but you could feed more people. My issue with modern practices is the exploitation of animals.
Jul 13, 2010
Rank: 3.3 / 5 (4)
Your second point is about sustainability. Unless we return to a subsistence lifestyle where everyone grows their own foods – there we can use more natural alternatives. You’re referring to animal poop when you talk about fertilizers that are non-petro. In this way, I think humans can live with animals in a synergistic manner and not exploit them. If honeybees pollinate my fruitrees of their own volition, I have no problem with that. If someone keeps chickens that are free to roam about as they want. They feed them and give them shelter and they produce fertilizer for the garden – I can’t see where the harm is there. In that scenario I’d be happy to lead a vegetarian lifestyle rather than vegan.
But aside from a subsistence lifestyle, I can’t see any alternative but veganism.

Removing the meat industries will only serve to starve those who cannot escape subsistence farming.
It is a crime of luxury and wealth. If you didn't have the wealth you wouldn't have the luxury.
You state that we exploit animals, well that's awfully nice of you to think about them that way but we're meat eaters. If we don't eat them other animals will eat them. They are prey, and through evolution they have come to fill a role. They eat the plant life so that it may reproduce and further evolve and we eat them so that they may reproduce and further evolve. Locking the world in some sort of pseudo steady state where animals and people hold hands and galavant down the road is utterly ridiculous. Again, your choice is always your choice, but don't even attempt to force it on others when it is ethically dubious at best.

Hahaha! I've been buying vegan from organic sources since I was a uni student paying rent and earning student wages. Sorry, but another invalid point.
A vegan diet is much cheaper than a diet that is filled with animal products. It is also less taxing on the health system. What are the main causes of heart attacks and cholesterol again? Definitely not food from plants. Also, go read The China Study.
>>but we're meat eaters
Erm, I'm not and neither are many others who are healthy. I have seen absolutely no evidence that convinces me that we're meant to eat meat. People can eat meat. Just like they can eat sugar, smoke, or inject crack. Doesn't mean those things are good for you.
I don't even know how to answer that final paragraph. It makes no sense at all.

The study is of Chinese subsistence farmers and what happens to them when they become wealthier and start eating meat.
The United Nations also has published a report called "Assessing The Environmental Impacts of Production and Consumption".

The wiki article makes no factual distinction as to the types of animals whose taxonomy is charted, and pointedly ignores the fact that not having a falsifiable theory regarding "opportunistic" carnivores in no way controverts the fact of their existence.
Also overlooked is the possibility that having a pronounced snout might be a bit of an adaptive liability for a biped.
Taxonomy-based classification of human diet is a flawed approach. Also, how does this account for a chimpanzee, or crow- for instance?
As far as the correlation of cancer with meat eating- there are a host of other factors at work as well. Obviously classification of the human diet as omnivorous would imply some balance in the amounts of various foods consumed, and therefore a more or less ideal ratio.
A MIXED diet with smaller amounts of fatty red meat(and fatty fish) yields a cancer rate decidedly lower on the scale, as combining foods offsets deficiencies contd

I won't debate that a higher proportion of food intake should be vegetable/fruit, but meat consumption is just as natural a part of human diet as an artichoke is. And for a very large part of the world, it is the only way to reliably obtain enough protein to even have a prayer of staying healthy.

Nevertheless I will address your point about populations with high meat and animal product consumption. The Inuit have one of the highest levels of osteoporosis in the human population. Inuit Greenlanders, who historically have had limited access to fruits and vegetables, have the worst longevity statistics in North America. Research from the past and present shows that they die on the average about 10 years younger and have a higher rate of cancer than the overall Canadian population.

I don't really know anything about Laplanders. I haven't gotten around to researching every pocket of individual cultures.
But another group is the Maasai. They eat a diet high in wild hunted meats and have the worst life expectancy in the modern world. Life expectancy is 45 years for women and 42 years for men. African researchers report that, historically, Maasai rarely lived beyond age 60. Adult mortality figures on the Kenyan Maasai show that they have a 50% chance of dying before the age of 59.

Yes, you can compare intestinal length, but it doesn't mean it's a valid comparison. Humans go to the extreme when pretreating their food: heating it; cutting, chopping, shredding, grinding, milling it; juicing it; predigesting it using certain tasty molds, yeast, and bacteria, or with enzymes; soaking in acids, bases, salts, oils, or alcohol; freezing and thawing, which disrupts cell walls and membranes. This tends to make the food easier to digest. Humans might not have shorter intestines because they are carnivores but because they are cooks.
