Kangaroo Care for Premature Babies

The British Medical Journal and the World Health Organization (WHO) are promoting a method of caring for small and preterm babies. It calls for holding the baby close to a parent’s naked chest. The WHO advises “immediate skin-to-skin care for the survival of small and preterm babies.” This method is called “kangaroo care” because it copies what kangaroo mothers do with the baby in their pouch.

In 1978, Dr. Edgar Ray Sanabria and Hector Martinez-Gomez started the technique in the maternity ward of San Juan de Dios Hospital in Bogota, Columbia. The country’s death rate for premature infants was 70% before this technique. In some locations, kangaroo care has reduced the death rate to 10%.

Babies put into incubators may be exposed to bright lights and loud noises, and there are not enough incubators to go around in many countries. Researchers say that when the babies are held against the bare chest of their mother or father, they pick up their parent’s heartbeat and breathing rhythms. They also feel the warmth. The doctors published the results of kangaroo care in the journal Curso de Medicina Fetal in 1983. UNICEF began distributing information about the technique worldwide.

Interestingly, both the mother and the father can provide this benefit to a premature baby. Hospitals provide wards where a parent can stay with the child. A premature newborn may take two to three weeks of kangaroo care to be strong enough to leave the hospital. Even then, parents can continue kangaroo care at home.

People who claim that a preborn baby is not a human at 32 weeks or less have no evidence to support that claim. The bond between a mother and father and a child is necessary for the baby to survive, and no mechanical device can substitute for the care of a loving parent.

Human Destruction by Artificial Intelligence

We have always had, and probably always will have, doom-sayers who predict the human race will be wiped out in the near future. From nuclear war to disease to hostile aliens, there have been countless books, movies, TV shows, and media reports of something that will soon destroy us all. The latest prediction is human destruction by Artificial Intelligence (AI). AI doom-sayers are now predicting the odds of AI wiping out humanity are one in ten and that this could happen within five years.

AI-powered ChatGPT and Google’s Bard can already pass the bar and medical licensing exams. On IQ tests, they score in the 99th percentile – genius level. Some say that AI, without human control or input, could create bioweapons, shut down financial systems, and eventually wipe out humans. One example of human destruction by Artificial Intelligence is that if AI were allowed to solve the climate crisis, its first step would be eliminating humanity. An atheist could claim that AI could wipe out any belief in God by showing that it can act as a god.

There are many kinds of intelligence, and they are all measured in different ways. My mentally-challenged son would score average intelligence on a verbal English language IQ test. However, on a test that involved shapes and simple mathematical logic, he would score a 25. The two tests measured different things. The biblical concept of God as the creator is that God created time, space, and matter/energy. AI is fabricated by humans and takes what is already created, reshaping it to a human frame of reference.

Could AI create chaos? Yes! Can AI take a human-created test structured by a computer and provide an answer another computer or human would accept? Of course! Is there a risk in letting any computer control human activity? Yes! Human destruction by Artificial Intelligence can only happen if we allow it.

All of us know by experience that computers are limited. They depend on electricity and proper data input and ignore human needs. Look at how many times airlines have been forced to shut down flights in recent years due to computer failures. Most fundamental is the fact that humans are not driven by data alone. We respond to psychological and spiritual needs, complex emotions, social needs, and environmental issues. Our relationship with God can make life a positive experience, but AI cannot address the uniqueness of humans.

The Nutritional Value of Oysters

We live in an age when worldwide food supplies are limited, and there is incredible food waste in America. However, one food source God has given us is present in all of the world’s oceans. It is the five species of oysters harvested in the United States and many places worldwide. The nutritional value of oysters and their availability makes them an important food source.

Oysters are a keystone species that filter and clean sea water by consuming microorganisms. The average female oyster will produce up to 100,000,000 eggs a year. However, humans’ indiscriminate harvesting of wild oysters has reduced oyster populations in the U.S.A. to only 1% of what they were in the 1800s. In addition to the wild oyster population, these mollusks can be grown in artificial environments anywhere. Artificial tanks can use the runoff from forests, wetlands, and marshes to feed the oysters.

The nutritional value of oysters is well known. According to WebMD, six medium-sized oysters would produce 50 calories, 1 gram of fat, 21 mg of cholesterol, 150 mg of sodium, 5 grams of carbohydrates, and 4 grams of protein. For an American on a 2000-calorie diet, this serving would provide 28% of the daily iron needs, 4% of the vitamin C, and 3% of the calcium. Oysters are also an excellent source of vitamin B12, essential for brain health. They are also rich in vitamin D, copper, zinc, and manganese, all micronutrients that may help to prevent bone loss and osteoporosis.

Our food shortages are not because God hasn’t provided what we need. Current problems of land use, waste disposal, and nutritional deficiencies would be over if humans decided they have had enough war, greed, selfishness, pride, and arrogance. If we would start wisely using what God has given us and applying what we know, we could end hunger and malnutrition on the planet.

The Careless Use of Chemicals to Control Pests

One of the significant challenges we face is dealing with biological pests. In the United States, the accepted pest control method is using chemicals to kill anything that affects crop growing, spreads diseases, or just annoys us. We use weed and vegetation killers, insect sprays, chemical treatments for trees, and chemicals for the soil to make our lives more comfortable and increase the food supply. Unfortunately, the problems caused by the careless use of chemicals to control pests become more evident as we see the collateral damage and the cost of chemical production and distribution.

The current battle over the potential cancer-causing effect of Roundup reminds us of the health damage Agent Orange caused for military personnel in Vietnam. On a personal note, my younger brother died from the effects of Agent Orange that he was exposed to during his military service. We need to realize that God has given us tools to control negative environmental influences without the careless use of chemicals.

Studies show that the collateral damage from air pollution and ground-level ozone includes increased heart disease, diabetes, obesity, and dementia. Even aggression among animals and humans increases when pollution levels rise. For example, a study of 70,000 U.S. cases showed more people were bitten by dogs on smoggy days.

American foulbrood is a bacterial disease that has wiped out many broods of honey bees and is apparently catalyzed by pesticides used on crops that bees pollinate. The U.S. Department of Agriculture has approved an oral honeybee vaccine against the disease. But, again, this is an example of collateral damage from the careless use of chemicals to control pests.

Natural pest control avoids collateral damage. For example, vineyard owners near Cape Town, South Africa, use a group of domesticated Indian runner ducks to eat the snails and bugs that infect their vines. In addition to eating the pests, the ducks leave natural fertilizer to nourish the vines.

People use bats to eat insect pests in various places worldwide. Locust swarms are not an issue where bat populations are large. Insecticides can cause the death of songbirds, and as the bird populations decline, insect swarms increase, creating more problems. Even removing fish and frog populations harms pest control, as fish and frogs eat many insects and their larvae.

God has built pest controls into our planet, but humans often upset the balance. Restoring natural controls is within our reach, but people often believe the careless use of chemicals to control pests is easier and more profitable. Unfortunately, ignoring God’s design leads to health problems linked to the chemicals we dump on our land and into our rivers, lakes, and oceans.

Deciding Who is Human and Who Isn’t

The Bible tells us that humans are created in the image of God, giving us a spiritual nature – a soul. That means all races and sexes of humans are equal. Galatians 3:28 says it well, “you are all one in Christ Jesus.” While that is speaking of Christians, it applies to all humans since anyone can become a Christian. Those who reject belief in God have a harder time deciding who is human and who isn’t.

In the past, people justified slavery based on the claim that certain racial groups were not human and thus could be exploited by those deemed human. People today use the same illogic to justify abortion.

People use various criteria for deciding who is human and who isn’t. For example, when I was a young college student in the 1950s, we were told that the ability to make and use tools was the deciding factor. That teaching was nullified when researchers found that many animals make and use tools. For example, researchers have seen macaques in Phang Nga Bay in Thailand crack nuts with stones and discard sharp flakes, similar to early human tools.

More recently, anthropologists have suggested that the ability to recognize yourself in a mirror is evidence of self-awareness and is a cognitive ability unique to humans. One reason for this interpretation is that chimps and orangutans show they recognize themselves when they look in a mirror. That led to the conclusion that chimps, orangutans, and humans are all one family. However, a recent study of bluestreak cleaner wrasses by cognitive scientists at Osaka Metropolitan University in Japan has shown that these inch-long fish can recognize themselves in a mirror.

When researchers put a parasite-like mark on cleaner wrasses’ throats and allowed the fish to see their reflection in a mirror, they rubbed themselves on rocks to remove the mark. The wrasse could also pick its picture out of four photos that included three other wrasses. It’s essential to point out that self-awareness allows the physical survival of these fish because the wrasses eat parasites off the bodies of other fish. Knowing which fish will seek their help and which will eat them involves recognizing faces. This private awareness is a survival feature God has given them and doesn’t translate to emotions, thoughts, or language.

Humans are unique because of our spiritual nature, created in God’s image. Therefore, other criteria for deciding who is human and who isn’t are doomed to failure.

How Humans Avoided Being Eaten by Carnivores

Have you ever considered how humans avoided being eaten by carnivores in ancient times since we are essentially defenseless? We aren’t stronger than large carnivores, have no teeth or claws for defense, can’t run very fast, and do not have camouflage. So if you believe in survival of the fittest, it is pretty obvious humans should not have survived.

The research done by scientists reveals some incredible planning that allows us to exist. Consider these facts:

1) Human color vision is unique from that of other animals. For example, carnivores have dichromatic vision with two color cones, while humans have three. Hunters can wear red and not spook their prey because the prey does not have red cones.

2) Human vision has better angular resolution than other animals allowing greater spatial processing. We can tell where an animal is long before it can see us. When you walk your dog, you can see another dog long before your dog does, and you know how far away it is.

3) Humans have group behavior and group communication. Our speech lets a group know what the carnivore is and where it is. Our brains have sound and behavior connected. Carnivores have blind-deaf disembodied brains, meaning that sight and sound are not connected in a carnivore’s brain. Seeing a human or hearing one does not tell the carnivore whether the human is a useful food source. In addition, a carnivore would have to fight a group of humans prepared for its attack, requiring more energy to track down than the energy it would get from eating one of us.

Studies by biologists have shown that if zebras and antelopes had the same visual and sound connections to their brains as humans, lions would starve to death. So God’s design is how humans avoided being eaten by carnivores that are stronger than us. These features, and our intelligence, allowed us to survive.

After the flood, God told Noah, “And the fear of you and the dread of you shall be upon every beast of the earth, on every bird of the air, on all that move on the earth, and on all the fish of the sea. They are given into your hand” (Genesis 9:2). So that is how humans avoided being eaten by carnivores. God designed the life system, including the animals that physically could use man as a food source, in a way that humans could exist. We are unique in our spiritual makeup in God’s image and in our physical bodies designed for survival.

Understanding Animal Communication

We all remember the movie about a man who could uniquely talk to animals. Reports tell us that portable sensors and artificial intelligence may make a form of human-animal communication possible. Unlike that movie and the work of Penny Patterson using sign language to communicate with Koko the gorilla, the research goal is understanding animal communication instead of expecting them to use human language. Researchers use digital bioacoustics to record the animals and artificial intelligence to interpret what they say.

So far, scientists have studied the communication of bats and bees. Using tiny digital bioacoustic recorders, researchers at Tel Aviv University have gathered bat communication at frequencies above the limit of human hearing, over 20,000 hertz. Computers lower the frequency and slow it down to make it audible to humans, and artificial intelligence compiles the data to make it intelligible. Gerry Carter at Ohio State University has determined that bats have individual names, or “signature calls.” They argue over food, and mother bats communicate with their babies.

Understanding animal communication can involve more than sounds. Dr. Tim Landgraf at Freie Universitat in Berlin has deciphered bee communication, which involves both sounds and body movement. He has decoded the signals which tell other bees where to find nectar or warn of danger. Landgraf even built a robot name RoboBee that can enter a hive and control what the bees do. For example, when he put nectar in a place where no honeybee had visited and then told the bees where the nectar was, they went there.

Helping animals avoid pollution and directing them to safe food sources are potential applications of this technology. It is essential to understand the big difference between communication and language. These examples and future research with animals involve communication. Language is far more than communication and deals with culture, morals, and symbolism. As this field of understanding grows, its uses will also increase, and ethical concerns will become apparent.

One has to wonder how Adam and Eve communicated in the garden. They certainly did not speak English. Bat communication is obviously different from bee communication. Understanding animal communication is challenging since every animal is different, but that shows another level of design that science is just now beginning to understand. The more we learn about the creation, the more we have to be amazed at the wisdom of the Creator.

Willing to be Mothers

The abortion issue has brought into focus the uniqueness of women who are willing to be mothers today compared to 50 years ago. In 2023, many women consider the demands of motherhood to be excessive. Trans advocates are pushing girls to become boys so they do not have to go through childbirth and motherhood. People are correct in saying that women have often been unfairly treated by denying them equal pay or job opportunities. However, abortion is a different issue because it involves another life.

From a scientific and medical standpoint, when a baby is conceived, it is a human being. A woman’s choice has allowed the baby to come into existence. People obey or disobey God’s moral instructions by choice, and whether the baby is allowed to live is another moral choice. Our culture faces a significant moral decision. Will we allow humans to destroy another human whose existence causes unwanted demands?

Abortion rights advocates campaign on the idea that a woman has the right to choose what to do with her body. They consider pregnancy as just a change in her body, not the production of another human being. However, morning sickness and microchimerism clearly indicate that the baby is not just an extension of her body. (We have discussed microchimerism before HERE and HERE.)

A major point often overlooked in the abortion debate is that having a baby and being a mother are two different things. My first wife was a great mother but never experienced a pregnancy. Some have said that a mother has less pain in having a baby than in raising one. As adoptive parents of three wonderful children, we went through the pain of raising children and did so joyously. There are scores of women in today’s world who are willing to be mothers and desire to take on the role, but for physical reasons, like my wife, are unable to become pregnant.

In 1 Timothy 2:15, Paul addresses the significant role uniquely available to most women: “Yet she will be saved through child-bearing…” Timothy was a great ambassador of God because his mother, Eunice, and grandmother, Lois, raised him in God’s Word. Of course, a woman can be of great service in other capacities if she chooses, and the Bible is full of examples of such women. However, being a mother and raising children who will positively change the world is what Mother’s Day is all about. Unfortunately, in today’s world, fewer women are willing to be mothers, so we thank God for women of faith who accept and carry out that responsibility.

Eight Billion People on Earth

In November of 2022, the human population hit eight billion people. That means eight billion people need food, shelter, and energy for transportation and protection from the elements. In Genesis 1:28 and 9:1, God told Adam and Eve and later Noah and his family to “be fruitful and multiply.” Then the text uses the Hebrew word “mala” the Earth. Mala can mean fill, replenish, satisfy, accomplish, or confirm, according to Strong’s Exhaustive Concordance.

God’s command to early humans told them to take on the responsibility of caring for the planet. It does not mean their only purpose would be to have lots of children. God expects us to control and care for the creation, not merely endure its challenges. There is a fundamental difference between the biblical concept of our relationship to the planet and our present state, which has caused poverty and starvation.

The Christian system teaches a one-man/one-woman system of marriage as opposed to polygamy. It also teaches that being a father places responsibilities upon men. Passages like Ephesians 6:4 and Colossians 3:21 make it clear that fathering children gives men a responsibility to encourage and guide them.

The quality of life for Earth’s eight billion people depends on how we manage the issues of population control and caring for the environment. The teachings of Christ support the nurturing of the Christian family. The selfish and reckless placing of pleasure above all else brings pain to the individuals who embrace it and tragedy to human society. Promoting and following the Christian system of values is essential for human flourishing, and the collateral damage produced by not following it is becoming increasingly evident.

Use of Cannabis by Seniors

The use of marijuana to treat chronic pain and discomfort like arthritis has been widely publicized and legalized in many states. So naturally, those of us who are older look for any way to relieve the aches and pains that come with age. Because of that, the use of cannabis by seniors has increased dramatically.

Certainly, we should use anything God has given us to relieve human discomfort as long as it is not harmful. We must understand that one of God’s injunctions is to take care of the body, which the Bible says is the dwelling place of God’s Spirit (1 Corinthians 3:16).

We are responsible for ensuring that what we use to relieve discomfort is good for us and doesn’t harm our bodies. That means we must use caution and listen to research about so-called miracle cures. But unfortunately, new studies of the use of cannabis by seniors have raised a red flag about its safety.

The Journal of the American Geriatrics Society for January 9 reports on visits to emergency departments in California, where marijuana has been legal for any use for several years. Cannabis-related visits to emergency rooms by seniors (ages 65 and older) rose from 366 in 2005 to 12,167 in 2019.

Unfortunately, there is big money in the marijuana business, so cannabis merchants are promoting its use. However, you should use it under a doctor’s supervision. It should not be a matter of simply going to your local marijuana store and accepting all the claims they make for a “miracle cure” for whatever ails us.
