Waste of Food and Resources

One of the great tragedies of American culture today is the incredible waste of food and resources. People in many places around the world are surviving on less than 1000 calories per day, and starvation is killing vast numbers. Over a third of the food produced in the United States is never eaten. On average, Americans throw away a pound of food per person daily. The Environmental Protection Agency says the water and energy wasted in the United States in a year would supply more than 50 million homes.

The problem is not just the waste of food and resources but also how we use the land to produce food. The University of Oxford and Global Change Data Lab tell us that 50% of the world’s habitable land and 70% of freshwater goes to growing food and raising livestock. So when we throw away food, we also waste land and water resources. Three-fourths of the global ocean and freshwater pollution comes from agriculture. Greenhouse gas emissions from one year of food waste in the United States alone are equivalent to the emissions from 42 coal-fired power plants.

God has provided us with all the resources we need to feed the world’s population, but corporate greed, selfishness, ignorance, and a lack of concern for others cause the problem of world hunger. In Matthew 25:31-46, Jesus described judgment based on how we conduct ourselves in meeting the needs of others. The first thing Jesus mentions is that providing food for others is a responsibility of His followers (verses 35 and 42). One way we can do that is by avoiding the waste of food and resources God has given us and becoming leaders in the war against hunger. By living in obedience to Christ, we witness the reality of God to the world.

Eliminating Pigments in Paint

What if we could reduce environmental problems by eliminating pigments in paint? Creating colorful paint without pigments is possible by copying something found in the natural world. For example, butterflies, birds, fish, and cephalopods use structural color to create their dazzling beauty. Light, rather than pigments, creates structural color.

Debashis Chanda and colleagues at the University of Central Florida have researched eliminating pigments in paint by using structural color. Pigment colors are artificially synthesized molecules, requiring different chemicals for each color. Structural color involves producing a geometrical arrangement of two colorless materials to make any color of the rainbow.

Chandra’s work produces a plasmonic paint using nanoscale structural arrangements of aluminum and aluminum oxide, both of which are colorless. Structural color controls the reflection, scattering, or absorption of light based on the geometrical configuration of the nanostructures. The research has placed these structural color flakes in a commercial binder to produce all the colors visible to the human eye.

Unlike pigment color, structural color never fades. Another advantage is that it reflects infrared radiation, so the material under the paint can stay 25 to 30 degrees F cooler than with chemical paint. Also, plasmonic paint is lighter weight because it can produce saturated colors with a thinner paint layer. In addition, since the colors will not fade, there may not be a need to repaint as often. Finally, eliminating pigments in paint reduces chemical substances that can cause environmental impacts.

With these advantages, structural color plasmonic paint may be the paint of the future. Interestingly, structural color is another thing we learn from studying the natural world. Often the colors we see in living things come from structural color rather than pigments. This is one more example of the intelligence God built into the world. We continue to learn exciting new ways to improve people’s lives by mimicking what God has already done. Like velcro, penicillin, bird wings, and lizard lungs, we are blessed by copying God’s design.

Tool Use Discoveries in Anthropology

Scientific articles about tool use as an indicator of pre-human activity in the distant past may have to be rewritten. New discoveries show that the “tools” some anthropologists claimed were used by ancient hominids may be stone flakes accidentally created by monkeys.

Researchers have observed long-tailed macaques in Thailand using rocks to pound open palm nuts. When they use rocks containing flint or quartz, they create flakes or shards. Those fragments are very similar to some sharp-edge stone fragments researchers previously thought were created by ancient humans in East Africa.

Scientists have used what they call intentionally produced sharp-edged stones as proof of the evolutionary development of emerging humans. They used the “flake technology” to infer the degree of cognitive ability, including knowing how to select the types of rocks to give specific properties for making tools. Despite this “new” research, experienced field workers had previously observed monkeys inadvertently producing stone flakes and sometimes even using them as grooming tools.

Today’s anthropologists have moved beyond tool use to determine whether a specimen was human. They can sometimes use DNA found in the remains of the individuals. DNA studies have led to the understanding that all humans are related and that the gene pool has been thoroughly mixed over the ages.

The biblical reference is very simple. The name “Eve” means the mother of all living humans (Genesis 3:20). “Adam” means “of the ground,” referring to the fact that our physical bodies consist of elements found in the earth. “In the sweat of your face shall you eat bread until you return to the ground, for out of it you were taken. For dust you are, and to dust you shall return” (Genesis 3:19).

What sets humans apart is not tool use but our spiritual makeup. All humans are made in the image of God. We are all one physically, and the Bible calls us to become one spiritually. (See Galatians 3:28 and Ephesians 2:14.)

What Are the Chances?

Advocates of unguided naturalistic evolution say that evolution could have gone in many directions, and we are lucky to be here. But what are the chances of evolution producing you and me as we are today? Evolutionists would say the changes are 100% since we are already here. But, if we go back to the cosmic creation event, or “big bang,” the chances that we would have evolved are nil. On the other hand, if God planned and guided the creation because He had us in mind, the chances are 100%.

The DNA that makes us who we are physically is a highly complex strand of information. What are the chances that it could have written itself by chance? First of all, information comes from intelligence, not chance. Calculating the likelihood of something after it has happened is a statistical fallacy. After all, DNA is here, and so are we, so the chances are 100%. But what are the chances if we go back before the fact? What are the chances that non-living chemicals could come together in a just-right way to form the first living cell? Then what is the statistical evidence for that first cell multiplying and modifying by random chance mutations and natural selection to create humans?

One imagined scenario involves a billion chimpanzees typing on a billion keyboards for a billion years, accidentally typing one line of Shakespeare. What are the chances of that? Well, the short answer is that it will never happen. Computer keyboards have various numbers of keys, but the old-fashioned typewriters had 58, so let’s go with that number.

Forget Shakespeare. Look for the line “I love you more.” without quotation marks. That is a total of 16 letters, spaces, and a period. With 58 keys and 16 letters, what are the chances of accidentally typing that line? To compute that, you would have to multiply 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58 X 58. That is a total of 16 times. If you want to try it, go ahead, but it will probably exceed the capacity of your calculator. The answer would be 16.4 trillion quadrillion typing attempts.

Typing continuously at a speed equivalent to 45 words per minute, it would take 2,100 trillion years to have a 50/50 chance that one of those chimps would type that phrase. Absolutely nobody thinks that the Earth is anywhere close to 2,100 trillion years old. Nobody even suggests that the universe is that old. For this thought experiment, we are only looking for one short line of text, “I love you more.” That is nothing compared to the complex system of life on this planet.

The bottom line is that we can’t explain life or the fine-tuned physical constants of the universe by chance alone. But we can explain those things if God planned and guided the creation because He had us in mind. With God, our chances of being here were 100% from the beginning. (See Genesis 1:1.)

Elephants Show Design and Purpose

Skeptics have maintained that our planet cannot support animals as big and requiring as much food and water as elephants. Such comments are a product of ignorance and the desire to show that a wise Creator could not have designed life on Earth. However, the more we learn about them, the more we see that elephants show design and purpose.

Elephants eat 200 to 300 pounds of food and drink up to 40 gallons of water every day. They can spend 75% of their day eating, and that fact has fueled the skeptical view. What needs to be better understood is that almost 50% of the plant material they eat leaves their body undigested. This makes the elephant the gardener of the rainforest, providing seeds and water in places that would otherwise be barren.

An elephant’s trunk is an incredibly sophisticated piece of equipment with 40,000 muscles that can bend in nearly any direction. An adult elephant’s trunk can pick up a 700-pound weight, but it is sensitive enough to pick up a flower. Elephants can suck up and expel water but do not drink through their trunk – it is not a straw. An elephant’s sense of smell is twice as keen as a dog’s and can detect the scent of food or water 10 miles away.

Elephants use infrasonic sounds to communicate with one another. These are frequencies lower than 20 cycles per second, the lower limit of human hearing. Using low frequencies allows the sounds to be transmitted over very long distances. Studies have shown that elephants can communicate with one another over a span of six miles. Elephant hearing does not just involve its ears. They also hear through nerves in their feet, and their hearing is sensitive enough to distinguish between human voices.

Elephants have the largest brain of any land animal, and the memory section is larger and denser than that of humans. The adage of having a memory like an elephant recognizes this ability, which has shown to be useful in situations such as remembering where water holes were 12 years ago. The design of elephants is so complex that attributing it to blind chance does not seem to be the best explanation. Seeing that elephants show design and purpose, we recognize that life is the product of an intelligent Creator.

The Complex Design of Insect Brains

We may see insects as very simple organisms, but scientists see the complex design of insect brains. The human brain has over 80 billion nerve cells, each with about 10,000 connections. To understand the wiring in the human brain, you have to start small. For that reason, scientists mapped the 548,000 connections in the brain of a fruit fly larva. The goal is to learn how to treat disorders in the human brain.

The scientists had to slice the tiny brain into thousands of very thin sections and then use an electron microscope to capture an image of each slice. They could only accomplish the analysis by using powerful computers and specialized analytical tools. Even though they are small, fruitfly brains have regions for decision-making, learning, and navigation. In addition, they have left and right sides, like human brains.

Scientists call the complete brain wiring connections the “connectome,” and this work has practical applications. If we could understand the human brain’s connectome, we might be able to treat learning disorders, schizophrenia, and behavioral issues. Although researchers have been able to map the brain of the fruit fly larva, they are still far from mapping the brain of an adult fruit fly. Mapping the human brain will be even more challenging.

As we read data about the complex design of insect brains, we see how incredible the design of life is. The brain is a vital part of our existence and is far more complex than any computer humans might develop. To think that this complexity could be the product of blind chance processes requires faith beyond the thinking of any reasonable person.

The complex design of insect brains tells us that the “Wisdom” spoken of in Proverbs 8:12 and 22 demonstrates God’s incredible engineering and design. “I wisdom dwell with prudence and find out knowledge of witty inventions … the Lord possessed me in the beginning of His work.”

The Misunderstood Bats

What animals have been maligned and villainized the most by humanity, yet they are the unsung heroes of the animal kingdom? The Nature Conservancy and Bat Conservation International say the misunderstood bats fit that description. People think that bats hunt human victims and drink blood. On the contrary, Vampire bats do not go after human victims and are shy and gentle in behavior. They also only make up a tiny percentage of the total bat population.

Studies of the Bracken Cave bats in Texas show they eat 140 tons of flying beetles, winged ants, and moths every night, saving a billion dollars in crop damage. That is just in one area of Texas, but other bats eat their body weight in insects every night. Bats also are essential pollinators and disperse hundreds of seeds. Bats are vital to the balance of our natural world, and scientists studying bats tell us that they are declining in number. Can you imagine what life on Earth would be like if we eliminated the animals that eat insects?

As a teenager in southern Indiana, I was a spelunker – one who explores caves. The caves we explored had massive numbers of bats, and several times we were in the caves when the bats were flying out for their feeding binges. I never was bitten by a bat, and they used their echolocation to avoid us. When we found huge piles of bat guano, it never occurred to me that it all came from bugs they had eaten.

God has intelligently designed the systems of life on planet Earth, and we need to care for and protect them. When humans destroy animals such as the misunderstood bats, we invite disaster for our well-being.

Black Heron Canopy Feeding

If you watch animals in the wild finding food, you will see some amazing techniques that are hard to believe could be the product of blind chance. In many cases, the food-finding system has so many parts that it would take various simultaneous changes for them to happen by chance. Securing food is often hazardous for the animal, but eating is a higher priority than avoiding danger. An example of all this is the canopy feeding of the black heron (Egretta ardesiaca) in Sub-Saharan Africa.

The jet-black color of the black heron causes two problems for the bird. One is that there is no camouflage in its coloration, so predators have no trouble seeing it. The black heron is very obvious from above or on the ground. The other problem is that being black means the bird is in danger of overheating because black absorbs solar radiation in the form of heat.

These problems make you wonder about the wisdom of the black heron being black. This is where we find an ingenious design feature built into the bird, allowing it to have all it wants to eat. The black heron eats fish, but finding fish is challenging for all fish-eating birds. Black herons solve this problem by spreading out their feathers in an umbrella-like fashion for what is called canopy feeding. Small fish in the area looking for shade are drawn to the bird’s canopy. Because of its black color, the water under the bird is too dark for the fish to see the heron.

This cloak of darkness and the cooling create a huge attraction for fish. As they gather in the heron’s shade, the bird can simply choose which fish it wants to eat. This canopy feeding provides food for the heron while controlling the small fish population so they don’t overgraze the area.

To attribute the black heron’s canopy feeding to trial and error or chance requires some imagination. To attribute the black color, which seems counterproductive for the climate, to the survival of the fittest is beyond reasonable thinking. God’s design and creative wisdom are evident in all life forms. Romans 1:20 tells us that we can know there is a God through the things He has made, and the black heron is an excellent example of the truth of that statement.

Animal Communication in Turtles

An interesting fact of science is that researchers investigate the natural world in terms of human actions. An excellent example of that is our understanding of animal communication. Recent studies have shown that turtles have a rather complex system of communication which researchers have missed because the communication is very low-pitched and quiet. The frequency of the turtle communication is below 20 hertz, putting it below human hearing limitations.

With new listening devices, researchers have found that baby turtles chirp to one another while they are still in their eggs. They discovered this communication in giant South American river turtles called arraus. The apparent purpose is to coordinate their hatching time. When all the baby turtles come out of their eggs at the same time, it dramatically improves their chances of making it to the river before being snatched by a predator. The researchers also found that mother turtles use sounds to respond to the calls of their young and shepherd them to the water.

You can add turtles to the growing list of animal communication with sounds above or below the frequencies that humans can hear. Examples of subsonic or ultrasonic communicators are whales, fish, bats, and numerous birds. God has designed life to have maximum survival potential. Being able to communicate is just one of the tools that animals have been given to enhance that objective.

Every Life Form Benefits Humans

Genesis 1:31 tells us, “God saw everything that He had made, and behold, it was very good.” The creation is a carefully designed system that allows beauty and function, benefiting humans in every way. Every life form benefits humans in some way, but we may not understand how until we study all living things. Our websites and materials often point out surprising facts about how animals and plants benefit us.

Today we have many medicines, vaccines, and remedies for ailments derived from the creatures God created. However, many cures for human afflictions remain to be secured from other life forms that share the planet with us. Medical researchers are concerned that many creatures which might be able to help us cure disease and afflictions are becoming extinct because of the mismanagement of God’s creation.

Research on animal population changes from 1970 to 2018 shows that the number of birds, amphibians, reptiles, mammals, and fish declined by 69% during those years. The research was an exhaustive study of 5,230 species in 31,821 populations. The most significant loss was in Latin America and the Caribbean, where the decline was 94%. Africa was second with a loss of 66%.

The research also studied the causes of the decline in living things and found that overexploitation and habitat degradation were the main issues resulting in 70% of the loss. Pollution contributed to less than 10% of the decline. Thus, human greed and selfishness are causing most of the problems.

An old story tells about a man at the judgment asking God why He allowed him to die in a flood. God replied, “I sent you my workers with a canoe, a row boat, a motor boat, and an airboat, but you kept saying you were waiting for me to save you.” God’s creation design provides that every life form benefits humans. He has given us everything we need, from food to medicinal agents, but we continue to allow greed and selfishness to waste God’s provisions.
