Tools to Counteract Greenhouse Gases

People have paid much attention to the accumulation of greenhouse gases in our atmosphere because they play a significant role in global warming. The main culprit in the greenhouse gas list is carbon dioxide. Not only do we exhale this gas, but fires of all kinds produce it. With the recent major fires in Australia, there is even more concern about the amount of carbon dioxide in the atmosphere. But God has given the Earth some tools to counteract greenhouse gases.

The most efficient tool built into the Earth is a microscopic plant called a diatom. There are 12,000 species of diatoms in Earth’s lakes and oceans. Unlike phytoplankton, diatoms are encased in porous, intricately structured silica shells. Examined under a microscope, these silica shells are beautiful, and they are very resistant to change in shape. That means that the spaces between the shells can collect particulate material. So diatoms are used as filtering agents to filter water for swimming pools and as fillers for aerating soils in yards. The shells are used as diatomaceous earth, which is familiar to most of us, especially those who raise roses or tomatoes.

Diatoms can also absorb gases. In the oceans, they absorb massive amounts of carbon dioxide and lock it up in the ocean’s depths. Diatoms capture as much carbon dioxide as all the trees, grasses, and other land plants combined. The fancy latticework of the diatom is not just for humans to admire. Because of the twists and turns of their shells, the surface area of diatoms is much greater than that of smooth shells. The increased surface area maximizes photosynthesis and allows the diatoms greater energy for growth and reproduction.

The life expectancy of a diatom is about six days. Because the silicon is heavy, the diatom at death sinks to the ocean floor or lake, taking carbon with it. One solution to the buildup of carbon dioxide is to catalyze the growth of diatoms. Iron nutrients can do that, and seeding the oceans with iron might be a way to reduce the amount of carbon dioxide in the atmosphere.

Diatoms are one more example of the design built into Earth’s structure to allow the planet to exist over the long haul. While diatoms are not apparent to the human eye, they are tools to counteract greenhouse gases and a possible solution to a modern problem.

Michigan Fruit Trees and Global Warming

There are all kinds of evidence that we are in a period of global warming. Many of the examples don’t have so much to do with temperature as with heat. Glaciers, for instance, stay pretty much at the same temperature under the surface. But ice requires 80 calories of heat per gram to melt, without changing the temperature. You can see that when you put ice cubes in your tea. You can also see the effect of global warming on Michigan fruit trees.

We live in an area rich in fruit-growing with apples, peaches, pears, cherries, grapes, and blueberries being major cash crops. My friends who make their living with Michigan fruit trees are very upset with the current weather cycle because it has not been cold enough. Fruit trees require time and temperature to know when to blossom and when not to. They do this by a sophisticated design system. Most fruit trees need a minimum of 250 hours of temperatures between 35 and 50 degrees Fahrenheit (2 to 10 degrees Celsius), and some require up to 1000 hours. Temperatures below freezing don’t count.

The “chilling hours” are sensed by the buds on the trees, not the roots. The wisdom in this system is obvious. Michigan winters usually have many days when the temperature goes below 10 degrees C, but there are also those rare days when the temperature gets very warm. This past winter, we had fewer than normal hours in the required temperature range. The buds have not gotten enough chilling to tell them to open. If they didn’t have the built-in time requirement, you can understand what would happen. The first time the temperature dipped below 10 degrees followed by a warm day, the buds would open and blossom only to be killed by the next cold snap.

Trees that are native in southern latitudes don’t bear fruit well when they are moved north. God has suited plants to different climates as well as other environmental factors. Orchards are found near bodies of water for several reasons. One of them is the tempering effect the water has on the air temperature. The presence of Lake Michigan provides a heat sink for our Michigan fruit trees that is as important as the moisture itself. The Psalmist seems to have had some idea of this when he compares a righteous person to a tree: “Blessed is the man who does not walk in the counsel of the wicked … He is like a tree planted by streams of water, which yields its fruit in season” (Psalms 1:1-3).

My fruit-growing friends have learned to understand and work with God’s design for their trees, but sometimes weather anomalies can frustrate their best efforts.

Amazing Spring Timing

One of the things you hear people in our part of Michigan say is, “If you don’t like our weather, hang on for a few minutes, and it will change.” We have had a strange winter season. We had brutal temperatures, wind, and snow in early December, leading all of us to think it was going to be a terrible winter. As we got near the holidays, the weather became unseasonably warm. We waited anxiously for another blizzard like the ones we usually have after a warm spell in winter. It never happened. Now we see the amazing spring timing.

It was so warm in the winter that I worried about the glad bulbs I had dug up. I put them in buckets covered with moist newspaper and stored them in the garage for spring replanting. I was afraid they would leaf-out responding to temperature, but they seemed to be okay and had not budded out at all. The weather did turn cold, but not the sub-zero stuff we usually have. Now we are in mid-April and, even though it snowed two days ago (and is snowing again today), winter is essentially over, and I used my snowblower only once.

So now I just got the glad bulbs out of the bucket in the garage. They have been in an insulated, dark garage, covered with a foot of newspapers since I dug them up in October. Every single bulb has a green shoot coming out. They are ready to be planted. How did they know it was time? The temperature in the garage didn’t change. No sunlight got into the bucket.

I have always assumed that my daffodils, which are blooming like crazy, used the presence of direct sunlight and perhaps temperature to know when to come up and prepare to boom. The glads had none of those indicators available to them. I am not suggesting that the amazing spring timing is some kind of mystic intelligence that tells the glads it is time to go. Whether it is ultraviolet light or infrared that signals the glads, it is a highly well-designed system.

Amazing spring timing is fascinating. The hummingbirds seem to know when to come north. The sandhill cranes are circling overhead as they fly ahead of the weather systems that might otherwise threaten them. The baby deer are around in such numbers that no amount of predation threatens to wipe out the deer population. That is thanks to the synchronized births that seem to take place in almost all wild ungulates.

When God decided to challenge Job, He used the things that show design wisdom in His creation to convict Job of his ignorance. Job 38:39- 41:34 finds God challenging Job to look around and see God’s wisdom and power at work. There is no better time to see that than in the amazing spring timing. Let us all step away from the ills of humanity and look at what God has done.

God’s Seasons of Hope

We have mentioned before that God did not create the coronavirus that is causing so much pain to people worldwide. In this devastating epidemic, many of us have lost someone close to us. No one is minimizing the damage of COVID-19, but human greed and mismanagement have been the primary cause of it, not God. However, God’s seasons of hope can bring us through times like this.

One blessing that we should all be thankful for is the time of year when this pandemic has struck. It is now April. Geese are flying overhead. My daffodils are ready to bloom. A baby deer crossed my driveway this morning. The yard is greening up, and I will be outside rotor-tilling the garden and spreading fertilizer later this week. Experts say that viruses don’t like the ultraviolet light and high temperatures of the Sun, and the forecast is for clear skies and rising temperatures.

When Paul was teaching in Iconium (Acts 14), he encouraged his listeners: “Turn from these vanities to the living God who made heaven, and earth, and the sea and all the things that are in them. In the past God allowed all nations to walk in their town ways, but he did not leave himself without a witness, in that he did good, and gave us rain from heaven, and fruitful seasons, filling our hearts with food and gladness.” (Verses 15-18).

The rain has come and melted the last of the snow. There is plenty of food, and congregations who operate food banks are meeting the needs of people in their areas. Before long, there will be strawberries, asparagus, greens, and mushrooms available outside our doors. We can once again fill our hearts with food and gladness.

Let us find encouragement in Paul’s words as we enjoy God’s seasons of hope and look forward to a future free from this virus threat.

What Are Viruses and What Is their Purpose?

It is self-evident that we are all impacted by something called a “virus.” What are viruses, and what is their purpose?

The first clue about viruses was in 1898 when scientists discovered that the cause of foot and mouth disease in livestock was something smaller than any bacteria. Because viruses are about 100 times smaller than bacteria, they could not be detected until electron microscopes were developed in 1931. Since viruses were too small to be filtered out, scientists initially thought they were liquids. They were given the name “virus” which comes from the Latin word for poison.

Later, scientists discovered that a virus is a protein (DNA or RNA) molecule enclosed in a capsid covered by a protective layer of fat, or lipids. The virus in and of itself is inert and unable to reproduce. So what is their purpose? When they come in contact with living cells, they insert their genetic material into the host, so the cell now produces viral protein. This may produce harmful and life-threatening results. Among the illnesses generated by viruses are the common cold, influenza, smallpox, chickenpox, herpes, shingles, AIDS, polio, rabies, Ebola, and others.

If the protein is beneficial, the virus can produce a useful evolutionary change. In that way, viruses are tools to create new genetic products. In today’s world of genetic engineering, the process is called transduction. We have pointed out before that many times good things come from evolutionary change. God designed living things with the ability to change and adapt. Scientists use viruses as tools to affect desired genetic changes in agricultural products to produce high protein corn, for example. Some viruses attack bacteria, and they are called bacteriophages. As bacteria have developed resistance to antibiotics, scientists are interested in using bacteriophages as a defense against harmful bacteria.

If they are not living things, then what are viruses? They are sometimes called “organisms on the edge of life.” They are not fully living on their own, but they possess some characteristics of living things. Viruses are very fragile because the only thing protecting them is a thin layer of fat, known as lipids. If the fat is dissolved, the protein molecule disperses and breaks down on its own. That is why any soap or detergent will destroy a virus, and why washing your hands with soap and warm water is essential. Heat melts fat, so water above 25 degrees Celsius (77 degrees F) for washing clothes, dishes, or hands will destroy viruses. Any solution which is more than 60% alcohol will dissolve fat and destroy the virus, as will bleach in a 1 to 5 ratio to water. Antibiotics or bactericides do not affect a virus because they only work on living tissue. Antibiotics cannot kill what is not alive.

The problem with viruses is that when they are transferred from animals into humans, or even different animals, they can be destructive. Scientists believe that the current coronavirus (SARS-CoV-2) is active in bats where it causes no problems. When the virus jumped into humans, the result was destructive.

Then, what is their purpose? Viruses can be useful tools in their proper place. They are part of the way life continues to exist on a changing Earth. Mismanagement of animals and food can cause a virus to become an enemy of humans. We have a repeat of the Frankenstein phenomenon when a potentially useful concept turns into a monster because of misuse.

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.

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.

Wood – Natural Multipurpose Building Material

We have mentioned before that many human inventions are actually adaptations of things we see in nature. That applies to products from Velcro to high-strength materials to airplanes. However, there are times when we can’t improve on the natural product, so we use it as God created it. An example of that is wood. It’s a natural multipurpose building material. Wood is strong, durable, flexible, weather-resistant, lightweight, and non-toxic. Lumber from trees is the most common building material for homes and other housing structures.

How could there be such a well-designed and valuable natural multipurpose building material? Wood is produced in a living plant. Under the protective bark of a tree lies the cambium layer. It is the innermost layer of the bark where growth takes place. Each year, during the warm months, the cambium produces living cells, which become the new sheath expanding the trunk of the tree. The layers from previous years remain as the wooden skeleton giving strength to the tree. If you cut it down, you can count those layers as visible rings revealing the age of the tree.

The tree’s roots take in water with vital nutrients from the ground. Within the woody trunk, there are microscopic conduits called xylem carrying that water up to the leaves. Just outside of the cambium, another layer of micro-ducts called phloem moves sugar-water that the leaves produce using the amazingly complex system of photosynthesis. The phloem supplies nourishment that the cambium requires to build the new sheath of wood. When the growing season ends, the phloem carries the remaining nourishment to the roots for winter storage until next spring.

Trees often lose branches from wind, ice storms, other natural means, or by human intervention. When that happens, it can throw the tree off balance. The cambium steps in to build a thicker sheath on the side where the limb was lost, reinforcing the tree to bear the uneven load. When examining the rings of a felled tree, a ring that is thicker on one side indicates a fallen branch. The tree automatically takes care of the area of the lost limb by covering it with new annual sheaths.

Take a moment to look at the wood in your house. That natural multipurpose building material in the window and door trim, the floor, and your furniture was once alive. It was growing and transporting sap while the leaves converted sunlight and water into sugar-water to nourish the tree, and the cambium created new growth. The lines in that wood tell the story of days and years of rainfall, sunshine, wind, and changing temperatures in a forest somewhere in the world. The wood in your house is not there by accident, and we don’t believe the tree was a natural accident, but the work of a creative Engineer.

Trees Prepare for Winter

Imagine standing naked outside on a cold winter day. When winter’s chill comes, people take shelter. If we have to be out, we put on more clothing. Most animals have fur or feathers to help keep them warm, and they also seek shelter from the cold. Trees in winter can only stand there and take it for months at a time. So how do trees prepare for winter?

Living cells in plants or animals consist primarily of water inside a membrane. If you leave a bottle of water in your car on a night when the temperature drops below freezing, you know it will freeze and break the bottle. That is because water has the unique property of expanding as it freezes. The same thing can happen in living cells. If the water in the cell freezes, it will expand and rupture the membrane. Animals that are endothermic (warm-blooded) generate heat within their cells by burning sugar to produce energy. Plants make sugar using light energy. With a few exceptions, they don’t produce heat.

How do trees prepare for winter? They use a process botanists refer to as “hardening.” The cell walls become more permeable to allow water to escape. At the same time, sugars, proteins, and acids in the cell are concentrated into a syrupy liquid, which acts as an antifreeze. The spaces between the cell walls become filled with ultra-pure water filtered through the cell walls. Pure water without stray atoms to form a nucleus around which ice crystals can grow, will freeze only at a much lower temperature. With the cells filled with antifreeze and spaces between having only ultra-pure water that can be super-cooled without freezing, the tree is ready for what the winter brings.

How does the tree know that it’s time to harden for winter? Fall weather can fluctuate quickly and dramatically. A tree can’t depend on the fickle weather because it could easily be fooled by warm days that suddenly turn cold, causing it to freeze to death. Trees know when to prepare for winter because of the length of the days – the “photoperiod.” Weather is unpredictable. The Sun is absolutely dependable. When the tree senses a decrease in light in each 24-hour cycle, it knows winter is coming, even if the weather is unusually warm. The pattern of changing daylight and darkness is exactly the same every year, even though the weather is capricious.

God engineered this incredibly well-designed system. “Then God said, ‘Let there be lights in the expanse of the sky to separate the day from the night. They will serve as signs for seasons and for days and for years’” (Genesis 1:14). Thus God designed the system which says, “Trees prepare for winter.” It’s another engineering marvel from the Creator.

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.
