Viral Diseases and Christians

Listening to the media, you might conclude that we have a new threat to our survival in the COVID-19 virus, but that is not the case. Viral diseases have been around from the earliest days of human existence. Recorded history tells us that in 430 BC, a virus took root in Athens and killed two-thirds of the city’s population. Seventy-five million people died from the Black Death in the 14th century. One hundred million people died from the Spanish flu of 1918, and 500 million people were infected. In modern times entire native populations have been wiped out by virus infections. We have all heard of HIV, MERS, SARS, Ebola, H5N1, Nipah, and Zika virus epidemics and their massive numbers of victims.

Scientists studying each of these diseases have determined that they came to humans from animals. HIV originated in chimpanzees. MERS came from camels. SARS originated from bats and civet cats. We can trace COVID-19 to bats and soldierfish. The massive concern about the current coronavirus is that there are far more humans to contract and spread the virus than at any time in the past. Also, we are more concentrated in cities, are more mobile, and have close interaction regularly with animals. In the past 50 years, more than 300 pathogens have emerged. With the use of more animals as pets and as food, there is an increase in the diseases they bring to humans.

From a historical standpoint, the biblical injunctions about hygiene and animal husbandry avoided much of the viral disease problem. The identification of clean and unclean animals reduced human interaction with animals that carry disease. The elaborate rituals of washing and handling animals used as food not only had an aesthetic appeal but reduced the opportunities for disease transmission. The acts of quarantine for anyone showing symptoms eliminated the spreading of disease from one person to another. Pandemics in an isolated farming population was not likely.

As the human population increased, and cities became population centers, the incidence rate of viral diseases increased. Advancing science and technology gave brought the ability to control some diseases. Selfishness, greed, carelessness, and poor hygiene provide easy ways for viruses to spread. Instead of following God’s rules for cleanliness and the preparation of food, humans have employed destructive methods. This is especially true in cultures that have no connection to God’s instructions. It is no accident that the coronavirus for COVID-19 originated in China and in a food market there where food handling and animal managing is limited. It is also no accident that many of the viruses that have decimated human populations were spread because of sexual practices that ignore God’s instructions for sexual relationships.

This virus is not a tool of punishment forged by God. There are good viruses and harmful viruses. Using the intelligence God gave us and following His commands, we can eventually eliminate the effects of the bad ones. Meanwhile, Christians can help those who are infected. We can also work to improve the lifestyles of our friends and neighbors to reduce the spread of viral diseases.

Can We Produce Enough Food?

Some have said that this is the only command of God that humans have fully obeyed. Whether that is true or not can be debated. There is also debate about whether there is enough food for the enormous population of humans inhabiting this planet. Every day organizations trying to stop the hunger stalking our planet send us heart-breaking pictures of starving people. Did God err in commanding humans to multiply and then not providing enough food? Can we produce enough food for the population with what God has given us?

The February 3, 2020 issue of Time magazine carried a pictorial article about “planet-friendly eating.” The article highlights companies that are producing food from plants and insects. Some of the companies are:

1) Exo sells what they call “Cricket Protein Bar” and roasted crickets. They say that crickets are the perfect protein source, high in essential amino acids, B12, and iron.

2) Plenty grows salad greens indoors with wind and solar providing power. They plan to add strawberries to their production line.

3) Just (which was formerly known as Hampton Creek) produces an egg substitute from mung beans. You can buy it at Walmart.

4) Mosa Meat grows meat from animal cells cultured in a bioreactor. It won’t be practical until the cost can be reduced unless you want to buy a $280,000 hamburger.

5) Beyond Meat bypasses the animal cells to produce burgers and sausage from peas, beans, rice, and sunflower seeds. You can buy their product at thousands of grocery stores.

6) Odontella uses algae to produce a product with the texture and flavor of salmon. They call it Solmon, and it’s available in vegan grocery stores in Europe.

7) Huel makes drinks that are supposed to have the nutrition of a meal with 27 essential vitamins and minerals as well as protein, fat, fiber, and phytonutrients.

8) Solar Foods uses microbial fermentation of nutrients, water, and carbon dioxide to produce protein that resembles wheat flour.

Can we produce enough food using these new techniques? These ideas are encouraging because plants and insects can be grown inside so that pesticides or herbicides are not needed. Cultivation can be automated, reducing the massive overhead of conventional agriculture. Add to that, the fact that much of the food grown outside is wasted by pests, war, pollution, unpredictable weather, and bad agricultural practices.

American tastes may take a long time to adapt to these new foods, but a starving child in Africa is not concerned about how the food was produced if it satisfies hunger and provides nutrition. God has given us the means to produce all the food we need, but greed, waste, and ignorance have led to starvation and misery.

COVID-19 and the Origin of Disease

As I write this in Mid-February of 2020, over 2000 people have died from the coronavirus known as SARS-COV-2 or COVID-19. The cause of the virus has been the subject of many television shows, research papers, and religious rants. Scientific evidence concerning the virus is pretty clear, but the media has spread wild claims by nutritionists, religionists, and holistic practitioners that have misled many people. It is essential to separate the snake oil sellers from valid research and holistic claims from valid medical treatment. What is the origin of disease?

There are always religious extremists who will say that diseases like the Coronavirus are God’s punishment for sinful human beings. That claim violates the nature of God, and it is unsupported by the evidence. James 1:17 tells us that God is the giver of every “good and perfect” gift, and verse 13 clearly indicates that He does not tempt us with evil. Jesus never sent disease or punishment on any human being–not even Judas. By the same token, God does not prevent the natural consequences of sin or bad choices. Judas chose to destroy himself, but God did not strike him dead. It would be contrary to God’s nature to send a disease that would kill innocent people for any reason, and children and older adults are dying from this coronavirus.

So what is the origin of disease and the COVID-19 virus? Virtually all of the infectious diseases that humans experience are transmitted to humans from animals. HIV came into the human population from monkeys, and the SARs group of viruses came from animals. Many viral agents cause no problems for an animal, but when they are transmitted to humans, the virus runs wild and can kill. HIV causes no problems in monkeys, but when it gets into the human body, the result can be death. The coronavirus started in Wuhan, China, and appears to have begun in the Huanan Seafood Wholesale Market. Eating animals that are carrying the virus or keeping animals with the virus as pets make it easy for humans to become infected.

The Bible was written long before people understood bacteria, viruses, or the importance of personal hygiene. Despite that, it advised hygiene practices and ways of securing and preparing food that minimized the chance of epidemics like the one we are experiencing now. It appears that animals in China carried the virus, and due to Chinese diets and food preparation methods, it got a foothold in humans. COVID-19 creates an acute respiratory syndrome disease that quickly spreads from human to human and especially threatens people with weak respiratory systems.

The origin of disease is not a punishment from God. God did not send HIV to punish homosexuals, and He didn’t send COVID-19 to punish the Chinese for their government’s atheistic stance. At the same time, God’s love is demonstrated through His people. As everyone else is fleeing the Hubei province, Christian medical missionaries are moving in to provide help and treatment to those who are suffering.

Is Veganism a Solution to Global Warming and Animal Cruelty?

Genesis 9:1-3. Is Veganism a Solution to Global Warming?

So has this instruction, which humans have followed better than most of God’s commands, caused climate change? Should we all become vegetarians? Is veganism a solution to global warming and animal cruelty?

People have raised these questions in opposition to God, and to avoid the destruction of our planet. More than that, Peter Singer, in his book Animal Liberation, claimed that all animals are intelligent, feel emotions, and feel pain. He suggests that inflicting pain on animals is a barbaric tradition, and is unethical for modern humans. In addition to these objections, we have those who refuse to eat any animal products considering them to be unhealthy. Vegans avoid all dairy products, eggs, and any animal-based foods.

Certainly, humans are free to choose what their diet will be if they live in an area where a variety of foods are available. The reality, however, is that God designed humans to be omnivores. The statement of Genesis 9:1-3 recognizes that fact, and our bodies demonstrate it. Our teeth are made to both cut and to grind. Our digestive system is designed to handle a wide variety of foods. We are not only designed to eat many kinds of foods, but overloads of any one food type can cause problems for us. Too much plant-based sugar is not a healthy diet. Too many beans or too much honey can cause digestive issues for many of us. Many people have food allergies, especially if we eat those foods in large quantities. Having a balanced diet is critical to good health, and vegan diets can be unhealthy.

Raising animals does generate greenhouse gases, but grazing livestock causes only seven percent of the total greenhouse gases. Raising enough crops to supply the needs of all humans means deforestation and the use of pesticides, fertilizer, fungicides, and herbicides. In many places, growing food by planting crops is impossible, but animals can survive in those areas. Small-scale farmers totaling 1.3 billion people survive on animal products in places where relying solely on plant nutrients is impossible. Is veganism a solution for those people? It’s not even an option.

Any animal must indeed be able to feel pain to survive. The notion that raising animals for food is cruel and inhumane is short-sighted. Animals living in the wild can experience enormous pain. If a cow or goat escapes from its owner, it is in great danger from carnivores that do not dispatch their prey with no concern for their pain. Cattle raised with protection from carnivores, terrible weather, and disease are far better off than in the challenging environment of the wilderness. Is veganism a solution to animal cruelty or global warming? Not really.

A cow is not a human in a different body. They have no awareness of self, and instinctive drives dominate their behavior. While we anthropomorphize animal behavior (interpret what they do in human terms), the fact is that animals were created in amazing ways to survive. But animals do not have the spiritual properties that humans have.

Battle of the Splitters and Lumpers

As we have reported before, an interesting debate in the scientific community has been the battle of the splitters and lumpers.

The splitters are scientists who consider every fossil specimen they find to be a different species and give it a unique name. The famous anthropologist Louis Leakey was an example of a splitter attaching numerous new names to specimens he discovered. Later it turned out that several specimens which he had given individual names were actually just variations of the same species. In recent years, anthropologists have given individual names to variations of the Neanderthals. Subsequent DNA evidence showed that many of those forms were just racial variations of the same species.

Lumpers suggest that, in general, we see many variations in a species, but we rarely see a new species. In modern days, we have various races that can look very different but are one species. A pygmy and a seven-foot-tall NBA basketball player have vast physical differences, but they are fertile with each other and therefore are one species.

It is becoming increasingly evident that ancient forms were not as diverse as some have assumed. A dinosaur discovered in the 1940s was given the name Nanotyrannus. The picture is an artist’s conception of what they looked like. It is now becoming clear to many scientists that the Nanotyrannus is a juvenile form of Tyrannosaurus rex. Because of their size, the diet of these two specimens was different. With reptiles who continue to grow, they can have a dramatic change in physical makeup as they age.

When we carry the battle of the splitters and lumpers to the question of human origins, the implications become extremely important. Were there many different species of humans that were infertile with each other? Or were they all one species, and the physical variations were simply adaptions to the environment and diet? The Bible indicates that all humans are one and that we all descended from a common human ancestor. The lumpers tend to agree, and the evidence continues to accumulate, verifying that we are all one.

Value of a Whale

Many years ago, an atheist challenged my statement that everything in the creation had a designed purpose and filled a need. My atheist friend insisted that the whale is one example of a poorly designed creature with no purpose. He said that they eat massive amounts of the ocean’s food that could be eaten by other, more useful creatures. He also challenged that they contribute nothing to the ecology of the oceans. At the time, I didn’t have a good answer to why whales are useful. Whale oil seemed to me to be a weak answer. Since then, I have learned the value of a whale.

One of the things I love about science is that it continues to look for understandings of the world in which we live. New studies of whales have revealed some facts that show the whale is incredibly useful. The current winter edition of Defenders of Wildlife magazine reports data on the value of a whale.

Whales live a long time, and they accumulate carbon in their bodies. When the whale dies, it takes that carbon to the ocean bottom, removing it from the atmosphere. New research shows that each whale takes 33 tons (30 metric tons) of carbon out of the atmosphere. By comparison, a tree absorbs 48 pounds (22 kg) of carbon dioxide a year. In 60 years, which is the lifespan of most whales, a tree would remove one ton of carbon from the air. Whales play a role in removing the greenhouse gas that people are concerned about today.

In a whale’s lifetime, it will bring minerals to the ocean surface to stimulate phytoplankton growth. This plankton contributes more than 50% of the oxygen we breathe and absorbs 37 billion tons (33.5 metric tons) of carbon dioxide a year. Phytoplankton also sustains many fish species, and today, fishing is a 150 billion dollar industry.

So what is the value of a whale? Defenders of Wildlife maintains that each whale is worth more than two million dollars. God has a purpose for everything He created, but sometimes it takes us a long time to understand how His creatures help us.

Evolution Experiments and their Results

What if we could speed up time to test the concept of evolution? A scientist can’t wait millions or billions of years to study the process of natural selection as it creates new creatures. With that in mind, science must devise evolution experiments to study many generations in a much shorter time.

More than thirty years ago, Richard Lenski, who teaches at Michigan State University, began a project to study the evolution of the bacteria Escherichia coli, commonly known as E. coli. The project is called the Long-Term Evolution Experiment (LTEE). The scientist and his assistants carefully track the naturally-occurring random mutations in succeeding generations of E. coli. The environment for the bacteria is optimized for these one-cell creatures to grow and reproduce. Mutations are often harmful, but sometimes beneficial mutations lead to an improvement in the bacteria’s reproductive ability. Natural selection removes the bacteria with harmful mutations while those with beneficial mutations become more fit and reproduce. It’s what we call survival of the fittest.

Since 1988, the evolution experiment has continued, and scientists have kept careful records of the changes. Since the generation period of these bacteria is much shorter than that of humans, the study has gone through 70,000 generations. That is equivalent to more than 1.75 million years of human generations.

Through thousands of generations, there have been billions of mutations. Beneficial mutations that have lasted and accumulated amount to dozens. It is interesting that as time passes, successful mutations become increasingly rare. What the scientists are looking for is what they call “historical contingency,” which means a succession of small, almost inconsequential changes that accumulate to create significant changes.

So how has the E. coli changed after the 70,000 generations in this evolution experiment? The latest generation of E. coli can reproduce 70% faster than their ancestors. They are still bacteria. In fact, they are still E. coli bacteria. They have not mutated into some more advanced form of life. Dr. Lenski wants to see funding made available to continue the experiment for another 30 or even 300 years in the hope of seeing more dramatic results.

The LTEE has inspired other scientists to conduct evolution experiments. There is one at Harvard experimenting with yeast. Other scientists have experimented with fruit flies (Drosophila) to study the evolution of multi-cell creatures. They have bombarded the fruit flies with radiation and chemicals, changing light levels, and changing temperatures. After thousands of generations, the result has been mutant fruit flies with extra eyes or wings that didn’t function. They were still fruit flies.

The bottom line is that multi-generation evolution experiments have not resulted in new creatures or even greatly improved old creatures. The changes resulting from mutations and natural selection are either harmful or insignificant. God created animals to adapt and change due to environmental forces. Humans can change and sometimes improve animals by selective breeding. We see that very clearly in the many and very different breeds of dogs. But the evidence seems to indicate that only God can make a Canine or a Drosophila or an Escherichia—or a human.

You can read about the LTEE in the December 2019 issue of Discover magazine, page 49.

Rhino Horns and Poachers

There’s an amazing balance in the design of living things in this world. Many times humans throw the system out of balance. The rhinoceros is endangered not because of natural predators, but because of humans. Rhino horns can sell for thousands of dollars for their collectible value and their use in traditional Asian medicine, so poachers take advantage of that.

People are willing to pay a high price for the rhino horns for decorative or medicinal purposes. Killing these animals to use their horns for decorative trophies is shameful. Killing them for medicine is useless. Their horns consist of only keratin, which is the same as human hair or fingernails. In reality, the rhino horn is one really tough bundle of nose hairs glued together by material extruded from sebaceous glands in the animal’s nose. Superstitious beliefs have caused people to grind the rhino horns into powder and drink the powder in water or inhale it for supposed health benefits.

Wild rhinos numbered over half-a-million at the beginning of the twentieth century. Today there are fewer than 30,000. The International Rhino Foundation reports that three rhinos are killed each day by poachers just to obtain their horns. Trying to catch the poachers and stop them in the act is nearly impossible. Sawing off the rhino’s horn to make it unattractive to poachers is not a good solution. Science is looking for a better way.

Researchers from the University of Oxford have designed fake rhino horns that look and feel like the real thing. More than that, they have similar material properties to the real horns. They used hairs from the tails of horses (close relatives of rhinos) and cemented them together with a silk-protein based organic filler. Molding the structure into the shape of a rhino horn, you get a realistic imitation. Even examining the internal structure on cross-section reveals identical characteristics. It also handles grinding and high temperatures like the real deal.

These fake rhino horns can be manufactured rather economically, so the rhinoceros horn market could be flooded with them to disrupt the black market. Furthermore, when the horns are ground into powder for medicinal purposes, they will be just as effective real horns, meaning not effective at all.

Education doesn’t work as long as people have superstitious religious beliefs about the power of rhino horns. Perhaps the fake horns will help. The best answer to the problem of human abuse of this well-designed world is to realize that the Creator has given us the job of being caretakers of the creation. (Genesis 2:15) If we believe there is a Creator who holds us responsible, we have good reason to handle the Earth and the life on it with care.

Blessing of Turkeys

Turkeys are native to North America and live in the wild in every state except Alaska. They got the name “turkey” when Turkish merchants brought them into Europe. Since they were very abundant and easy to kill, indigenous North Americans domesticated them by around 800 BC. Many native American tribes considered turkeys to be a gift from deity. Ben Franklin thought that the turkey instead of the bald eagle should be the national bird of the United States. The blessing of turkeys is that they seem to be designed uniquely to meet the needs of humans.

Biologically, turkeys are of the order called Galliformes, which are ground-feeding birds that include chickens, grouse, guinea fowl, quail, and pheasants. Turkeys have large breasts, are poor fliers, and can adapt to almost any environment. They are omnivores that will eat just about anything they find on the ground.

From an evolutionary standpoint, it is hard to imagine how turkeys have survived. The only defensive weapon they have is the spurs on the feet of the males. Those of us living in areas where there are large numbers of wild turkeys have learned to be careful when around them. A turkey will attack anything it sees as subordinate. Recently in the spring mating season, a turkey flew through the open window of a pickup truck and attacked the driver, who required more than a dozen stitches. But a turkey is no match for a wolf, bear, or eagle.

When God blessed Noah and his family in Genesis chapter nine, He told them that all living things were delivered into their hands. He said that “every moving thing that lives shall be meat for you; even as the green herb have I given you all things.” The ease of domesticating chickens and turkeys comes from the planning and wisdom of God. The blessing of turkeys for Thanksgiving dinner is a special reminder of God’s creative wisdom. It also reminds us that we are responsible to care for the wonderful blessings of food God has provided.

Design of Symbiosis

One of the most interesting examples of design is the massive number of symbiotic relationships that exist in the natural world. These are arrangements two or more plants or animals benefit each other. Sometimes the design of symbiosis is essential for their survival.

Living by a river in Michigan, we see many animals that couldn’t exist without symbiotic relationships. Such common animals as squirrels need a designed symbiotic relationship that allows them gives them a growing abundance of food. We have a wealth of oak trees. In the fall, there are so many acorns on the ground that you can’t go barefoot. I counted 14 squirrels in my yard this morning, gathering acorns. They not only eat the acorns, but they bury them so that they will have a reserve of food for the rest of the year. They hide so many in so many different places that they eat only a small fraction of the acorns. The rest sprout and produce more oak trees. The oak forest spreads, and that means that the squirrel population can increase. The trees feed the squirrels, and the squirrels plant the trees in the design of symbiosis.

I grew up in the upper peninsula of Michigan. The bedrock there is mostly granite. Granite is hard, and water cannot penetrate it. That means that growing crops is difficult in the “U.P.” Animals would have it tough except that God has provided an animal with a symbiotic relationship to the soil and rocks of the area. To retain enough water to take the entire ecosystem through periods of drought, beavers construct dams in the streams. The multiple dams create small ponds that supply the water needs of plants and animals. What would otherwise be a sterile wasteland is a temperate paradise of woods with a wealth of birds and animals all dependent on the beavers. As beavers reproduce, their kits build their own system of dams and ponds, expanding the availability of water for all northern life.

What is the most expensive meal you can order when you go out to eat? Ask for the “diamonds of the kitchen” and you will be served a fungus called a truffle. A three-pound truffle recently sold for $300,000, and yet it is just a fungus. Truffles grow underground on the roots of trees. The truffle keeps bacteria and corrosive elements away from the tree roots, and the roots provide a protected place for the truffle to grow. This is another design of symbiosis. The way most people search for truffles is to have pigs root around trees until they uncover a truffle. Truffles are said to be the most expensive food in the world, but to locate them requires the use of animals that most of us don’t care to be around.

There are countless symbiotic relationships. The question of interest is, how does such a relationship develop? Is it merely by accident? We suggest God has looked at the nutritional needs of all of His creatures. In His wisdom, He has created living things in a way that links their food supply to other living things in their environment. The design of symbiosis is a marvelous creation of God.
