Too little room on the earth to feed all humans?

Recently I read a statement from an organisation for vegetarians in which it said that there isn't enough ground on the earth to grow all the crops necessary to feed all the animals necessary to feed humans.
This actually makes no sense at all.
There are large amounts of land in this world, about two thirds, on which it will not be able to grow any crops to feed humans. The animals that we mainly eat are animals that eat grass.
Cows, sheep and goats f.i. should not be mainly fed grains, that is bad for their health, they need a large amount of grass, weeds, etc., this goes for most of the animals that we feed ourselves with.
Therefore it is total rubbish to say that when the western world would eat less meat that this would give the third world countries more food and the people there would not starve to death. Basically the western world should feed the animals what they need to feed and then there wouldn't be such problems. I personally think it would be pretty sick to not use about two thirds of the land and overuse one third which would then end up being infertile.
We would also need to eat higher quantities of food to get the required proteins and fats if we were vegetarians and no longer getting concentrated protein and fat from animal products, so we would need to greatly increase vegetable and grain production and wearing this land out. As a result I can see starvation for all.
Of course vegetable growing can be more productive using organic techniques instead of factory farming, which is true, but that this would require a lot more human labor, which I would love to see happening. The majority of us would have to go back to hard labour in the fields instead of just a few now. This would of course benefit the health of most of us, but its unlikely to happen in practice as most people do not want to do hard labour. I personally love having a vegetable garden for our family, saves money and feeds all 6 of us easily throughout the year.

Fermentation, kefir & kombucha

In our family we are very interested in natural healthy foods.
Therefore we have gotten a kombucha mother or scoby, we also have scoby for milk kefir and water kefir. In case anyone is interested in getting that, I often have too much of it, as it grows and am willing to send it to anyone who wants it, just drop me a line.
We also do a lot of fermenting, we make sauerkraut, cortido, kimchi and other sauerkraut types. We have also made fermented carrots with ginger.
Furthermore we make our own bread, sourdough bread.
The good thing about natural fermented foods is that it is lactofermented and with that it makes the food more nutritional for us, we can digest it better and are better able to get the nutrients out of our food.

Spending time

With a newborn baby there is very little time for anything else than feeding and caring. Therefore I think I will post a bit less the next couple of months, as the house needs attention as well, dinner has to be made and kids have to be educated and cared for.
I do hope to be able to keep a bit on track here as I do love explaining how things feel for us with parenting etc.
For now, nursing needs to be done about every hour, as she is still small, that also means that there is a nice amount of dirty nappies, as she does feed very well.
Newborn babies need about 10 to 12 feeds in 24 hours, so it makes total sense that she does this, as she is sleeping quite well during the nights.
Furthermore we needed to make sure that feeding was going smooth, and that takes a few weeks to get that fully settled. In general mums are explained not to use any dummies or bottles before the first 4 weeks are done and that they have made sure that breastfeeding is well established, that will take about 4 weeks.

Natural age of weaning - Kathryn Dettwyler

This article is also one that I truly love, it is so well researched and so very true that I wonder why our culture has come up with such different ideas from what is natural.


http://www.kathydettwyler.org/detwean.html

My research has looked at the various "life-history" variables (such as length of gestation, birth weight, growth rate, age at sexual maturity, age at eruption of teeth, life span, etc.) in non-human primates and then looked at how these variables correlate with age at weaning in these animals. These are our closest relatives in the animal kingdom, especially gorillas and chimpanzees, who share more than 98% of their genes with humans. I came up with a number of predictions for when humans would "naturally" wean their children if they didn't have a lot of cultural rules about it. This interest stemmed from a reading of the cross-cultural literature on age at weaning, which shows that cultures have very different beliefs about when children should be weaned, from very early in the U.S. to very late in some places. One often hears that the worldwide average age of weaning is 4.2 years, but this figure is neither accurate nor meaningful. A survey of 64 "traditional" studies done prior to the 1940s showed a median duration of breastfeeding of about 2.8 years, but with some societies breastfeeding for much shorter, and some for much longer. It is meaningless, statistically, to speak of an average age of weaning worldwide, as so many children never nurse at all, or their mothers give up in the first few days, or at six weeks when they go back to work. It is true that there are still many societies in the world where children are routinely breastfed until the age of four or five years or older, and even in the United States, some children are nursed for this long and longer. In societies where children are allowed to nurse "as long as they want" they usually self-wean, with no arguments or emotional trauma, between 3 and 4 years of age. This interest also stemmed from the realization that other animals have "natural" ages of weaning, around 8 weeks for dogs, 8-12 months for horses, etc. Presumably these animals don't have cultural beliefs about when it would be appropriate.

Some of the results are as follows:

1. In a group of 21 species of non-human primates (monkeys and apes) studied by Holly Smith, she found that the offspring were weaned at the same time they were getting their first permanent molars. In humans, that would be: 5.5-6.0 years.

2. It has been common for pediatricians to claim that length of gestation is approximately equal to length of nursing in many species, suggesting a weaning age of 9 months for humans. However, this relationship turns out to be affected by how large the adult animals are -- the larger the adults, the longer the length of breastfeeding relative to gestation. For chimpanzees and gorillas, the two primates closest in size to humans and also the most closely genetically related, the relationship is 6 to 1. That is to say, they nurse their offspring for SIX times the length of gestation (actually 6.1 for chimps and 6.4 for gorillas, with humans mid-way in size between these two). In humans, that would be: 4.5 years of nursing (six times the 9 months of gestation).

3. It has been common for pediatricians to claim that most mammals wean their offspring when they have tripled their birth weight, suggesting a weaning age of 1 year in humans. Again though, this is affected by body weight, with larger mammals nursing their offspring until they have quadrupled their birth weight. In humans, quadrupling of birth weight occurs between 2.5 and 3.5 years, usually.

4. One study of primates showed that the offspring were weaned when they had reached about 1/3 their adult weight. This happens in humans at about 5-7 years.

5. A comparison of weaning age and sexual maturity in non-human primates suggests a weaning age of 6-7 for humans (about half-way to reproductive maturity).

6. Studies have shown that a child's immune system doesn't completely mature until about 6 years of age, and it is well established that breast milk helps develop the immune system and augment it with maternal antibodies as long as breast milk is produced (up to two years, no studies have been done on breast milk composition after two years post partum).

And on and on. The minimum predicted age for a natural age of weaning in humans is 2.5 years, with a maximum of 7.0 years.

In terms of the benefits of extended breastfeeding, there have been a number of studies comparing breastfed and bottlefed babies in terms of the frequency of various diseases, and also IQ achievement. In every case, the breastfed babies had lower risk of disease and higher IQs than the bottle-fed babies. In those studies that divided breastfed babies into categories based on length of breastfeeding, the babies breastfed the longest did better in terms of both lower disease and higher IQ. In other words, if the categories were 0-6 months of breastfeeding, 6-12 months, 12-18 months and 18-24+ months, then the 18-24+ month babies did the best, and the 12-18 month babies did the next best, and the 6-12 months babies did the next best, and the 0-6 months babies did the worst of the breastfed groups, but still much better than the bottlefeeding group. This has been shown for gastrointestinal illness, upper respiratory illness, multiple sclerosis, diabetes, heart disease, and on and on and on. Likewise, the babies nursed the longest scored the highest on the IQ tests. One important point to notice is that none of these studies looked at children who had nursed longer than 2 years. Anyone 18-24 month or longer was lumped into big category. Presumably, the benefits continue to accrue, as your body doesn't *know* that the baby has bad a birth day and suddenly start producing nutritionally and immunologically worthless milk.

However, no one has yet proved, either way, that the benefits of breastfeeding either continue or stop at two years of age, because the appropriate studies have not been done. The trend during the first two years is clearly for continuing benefits the longer you nurse. Clearly the phenomenon of dimishing returns is at work here -- the first six months of breastfeeding are clearly much more important in terms of the baby's nutrition and immunological development than the six months from 3.5 to 4.0 years. That doesn't mean that you shouldn't continue to provide breast milk if your baby wants and you don't mind. It would be like saying, "Well Mabel, we don't get very much income from that oil well anymore. Used to get $56 a month in royalties, now we're lucky if we get $25 a year. Guess we should tell that oil company just to keep their durn money." And Mabel says, in return "Good grief, Clyde, don't be ridiculous. That check still buys $25 worth of food. Where has your mind gone to now?"

Clearly, babies born in the U.S. don't have to contend with all the diseases and parasites and contaminated water that babies in Third World countries do. We have more supplementary foods that we can generally trust to be safe and clean. We can get our children immunized, and get them antibiotics for infections when necessary. The fact that we *can* does not mean that breastfeeding is unimportant. Breastfed babies still have the "edge" over bottlefed babies, even in a squeaky clean environment with wonderful medical care. They get sick less often, they are smarter, they are happier. Another important consideration for the older child is that they are able to maintain their emotional attachment to a person, rather than being forced to switch to an inanimate object such as a teddy bear or blanket. I think this sets the stage for a life of people-orientation, rather than materialism, and I think that is a good thing. I also can't imagine living through the toddler years without that close loving connection to a child going through enormous changes, some of which are very frustrating to the child. I could go on forever, but will stop here.

I hope this has been of help. These ideas are developed much more eloquently and in much greater detail in my chapter "A Time to Wean" in Breastfeeding: Biocultural Perspectives, being published by Aldine de Gruyter.

Sleeping through the night - Kathryn Dettwyler

The below article is one that I find very interesting and very true.

http://www.kathydettwyler.org/detsleepthrough.html



I am an Adjunct (semi-retired) Associate Professor of Anthropology and Nutrition at Texas A&M University, and I do research on infant/child feeding beliefs/practices both cross-culturally and from an evolutionary perspective, as well as research on children's health and growth. I know from first-hand experience that being a new parent is a difficult time of adjustment, especially when expectations don't match reality, especially when our culture has taught us that children should have certain needs/wants/behaviors and then our children don't seem to fit that mold. This problem of a mismatch between expectations and reality can be very difficult for new parents to accept and adjust to. Sometimes, some children can be encouraged/convinced/forced to fit the mold of cultural expectations, and they do fine. Othertimes, though they do eventually fit the mold, it is at the expense of their sense of who they are, their self-confidence, their view of the world as a safe and trusting place, sometimes, even, at the expense of their health or life. Probably nowhere do cultural expectations and the reality of children's needs conflict more than in the two areas of breastfeeding frequency and sleeping behaviors.

Human children are designed (whether you believe by millions of years of evolution, or by God, it doesn't matter) -- to nurse *very* frequently, based on the composition of the milk of the species, the fact that all higher primates (Primates are the zoological Order to which humans belong, higher primates include monkeys and apes) keep their offspring in the mother's arms or on her back for several years, the size of the young child's stomach, the rapidity with which breast milk is digested, the need for an almost constant source of nutrients to grow that huge brain (in humans, especially), and so on. By very frequently, I mean 3-4 times per hour, for a few minutes each time. The way in which some young infants are fed in our culture -- trying to get them to shift to a 3-4 hour schedule, with feedings of 15-20 minutes at a time, goes against our basic physiology. But humans are very adaptable, and some mothers will be able to make sufficient milk with this very infrequent stimulation and draining of the breasts, and some children will be able to adapt to large meals spaced far apart. Unfortunately, some mothers don't make enough milk with this little nursing, and some babies can't adjust, and so are fussy, cry a lot, seem to want to nurse "before it is time" and fail to grow and thrive. Of course, usually the mother's body is blamed -- "You can't make enough milk" -- rather than the culturally-imposed expectation that feeding every 3-4 hours should be sufficient, and the mother begins supplementing with formula, which leads to a steady spiral downward to complete weaning from the breast. Human children are also designed to have breast milk be a part of their diet for a minimum of 2.5 years, with many indicators pointing to 6-7 years as the true physiological duration of breastfeeding -- regardless of what your cultural beliefs may be. I can provide you with references to my research on this topic if you wish to read more.

The same is true of sleeping. Human children are designed to be sleeping with their parents. The sense of touch is the most important sense to primates, along with sight. Young primates are carried on their mother's body and sleep with her for years after birth, often until well after weaning. The expected pattern is for mother and child to sleep together, and for child to be able to nurse whenever they want during the night. Normal, healthy, breastfed and co-sleeping children do not sleep "through the night" (say 7-9 hours at a stretch) until they are 3-4 years old, and no longer need night nursing. I repeat -- this is NORMAL and HEALTHY. Dr. James McKenna's research on co-sleeping clearly shows the dangers of solitary sleeping in young infants, who slip into abnormal patterns of very deep sleep from which it is very difficult for them to rouse themselves when they experience an episode of apnea (stop breathing). When co-sleeping, the mother is monitoring the baby's sleep and breathing patterns, even though she herself is asleep. When the baby has an episode of apnea, she rouses the baby by her movements and touch. This is thought to be the primary mechanism by which co-sleeping protects children from Sudden Infant Death Syndrome. In other words, many cases of SIDS in solitary sleeping children are thought to be due to them having learned to sleep for long stretches at a time at a very early age, so they find themselves in these deep troughs of sleep, then they may experience an episode of apnea, and no one is there to notice or rouse them from it, so they just never start breathing again. Co-sleeping also allows a mother to monitor the baby's temperature during the night, to be there if they spit up and start to choke, and just to provide the normal, safe environment that the baby/child has been designed to expect.

Is this convenient for parents? No!

Is this difficult for some new parents to adjust to? Yes!

No doubt about it, the gap between what our culture teaches us to expect of the sleep patterns of a young child (read them a story, tuck them in, turn out the light, and not see them again for 8 hours) and the reality of how children actually sleep if healthy and normal, yawns widely.

But the first steps to dealing with the fact that your young child doesn't sleep through the night, or doesn't want to sleep without you is to realize that:

  • (1) Not sleeping through the night until they are 3 or 4 years of age is normal and healthy behavior for human infants.
  • (2) Your children are not being difficult or manipulative, they are being normal and healthy, and behaving in ways that are appropriate for our species.

Once you understand these simple truths, it becomes much easier to deal with parenting your child at night. Once you give up the idea that you must have 8 hours of uninterrupted sleep at night, and view these nighttime interactions with your child as precious and fleeting, you get used to them very quickly.

I highly recommend Dr. Sears' book on Nighttime Parenting [available from the La Leche League International Catalogue]. Our children's early years represent the most important and influential time of their lives. It passes all too quickly. But meeting your child's needs during these first few years will pay off in many ways in the years to come.

Study: Spanking can bring problems later

The next article is no news to me.
I actually have been convinced of it for years already, but now there has been a study done after it.

http://news.yahoo.com/s/ap/20080301/ap_on_he_me/spanking_study_3a

DURHAM, N.H. - New research by a University of New Hampshire domestic abuse expert says spanking children affects their sex lives as adults. Professor Murray Straus concludes that children who are spanked are more likely as adults to coerce partners to have sex, to have unprotected sex and to have masochistic sex.


Other studies have shown the link between spanking and physical violence, but Straus said his research is the first to show a link between corporal punishment and sexual behavior.

"My underlying motive was to bring this to the attention of parents and of more people," Straus said, "in the hope it will help continue the decrease in the use of corporal punishment."

Straus, co-director of UNH's Family Research Laboratory, conducted a study in the mid-1990s in which he asked 207 students at three colleges whether they'd ever been aroused by masochistic sex. He also asked them if they'd been spanked as children. He found that students who were spanked were nearly twice as likely to like masochistic sex.

He has bundled that study with three new ones that explore the connections between corporal punishment, coerced sex and risky sex. He presented all four studies this week at the American Psychological Association's Summit on Violence and Abuse in Relationships in Bethesda, Md.

Straus said his study found adults who were spanked as children are more likely to coerce their partners to have sex.

Straus asked 14,000 college students in 32 different countries whether they strongly disagreed, disagreed, agreed or strongly agreed with this statement: "I was spanked or hit a lot before age 12." He also asked whether they had ever verbally or physically coerced an uninterested partner to have sex.

He found a big difference between students who said they'd been hit a lot before age 12 and those who said they hadn't. For every increased step on Straus's four-step scale of agreement, men were 10 percent more likely to have verbally coerced sex from a partner by insisting on sex or threatening to end the relationship if the partner refused. Women were 12 percent more likely to have done that.

Previous studies have shown that 90 percent of parents strike their toddlers, a statistic that's held steady throughout the 30 years Straus has researched corporal punishment. Meanwhile, the number of parents who hit older children has drastically decreased. Straus said it's unclear why, though he has some theories. One is that 2- and 3-year-olds are less likely to respond to repeated verbal warnings.

Straus said he would like more pediatricians and child-rearing experts to warn against spanking. He'd also like lawmakers to take a stand by dedicating state money to teaching parents about the dangers of corporal punishment.

"The best-kept secret in child psychology is that children who were never spanked are among the best behaved," Straus said.
