Ecosystem Design and Stewardship

Ecosystem Design and Stewardship on Planet Earth

An ecosystem is a complex network of living and non-living things interacting with one another in a specific environment. It includes all the living organisms, such as plants, animals, and microorganisms, as well as the non-living components, such as air, water, soil, and climate. These living components are adapted to the non-living components in an interdependent system, with each relying on the others. We see ecosystem design everywhere we look on planet Earth.

Ecosystems exist in water environments, from ponds to streams to rivers to the oceans. They exist on land in forests, mountains, and deserts. They vary from tropical rainforests to frozen tundra. Each ecosystem has a unique balance of species, with each species playing a specific role. This balance is maintained through various mechanisms, including competition, predation, and mutualism.

Ecosystem design provides many vital services affecting human life, such as water filtration, air purification, and food. At the same time, humans have a profound impact on ecosystem management through deforestation, destruction, and pollution. Careless actions of humans can disrupt the delicate balance of ecosystems, leading to a decline in biodiversity, the extinction of essential species, and climate change.

Conservation and management efforts aim to protect and restore ecosystems and maintain their resilience. This involves protecting habitats, reducing pollution, and managing human activities to minimize ecosystem harm. It also requires monitoring and understanding environmental change and taking steps to reduce or correct human-caused impacts. As we protect ecosystems, they provide services critical to life on this planet. That is part of ecosystem design.

An ecosystem is an ecological system. As we think about the multitude of ecosystems, large and small, localized and widespread, we must realize that they are systems. Do systems happen by accident, or do they require intelligent planning? Can complex things come together to form an efficiently-functioning ecosystem on their own? Every living thing consists of many complex systems within the cells, organs, and whole bodies. Ecosystem design involves systems within systems within systems working together in balance.

Can efficient, balanced systems happen without a system designer? If there is a Designer of Earth’s ecosystems, as I believe there is, we owe it to Him to take care of what He has given for our existence and enjoyment. Genesis tells us that God gave humans the job of managing the creatures and ecosystems of planet Earth. (See Genesis 1:28.) We must avoid the rebuke the rich man gave to his unworthy steward in a parable Jesus told. “What is this I hear about you? Give an account of your stewardship, because you can no longer be my steward” (Luke 16:2).

Ayahuasca Drug Use in Churches

Ayahuasca Drug Use in Churches
Ayahuasca Brewing in Ecuador

As our culture turns away from God and the Christian system of living, we have a vast void that many people fill by turning to recreational drugs. Drug promoters try to convince people that they offer solutions to the negative human experience. For example, we now see “churches” that advertise a quick way to have a spiritual experience using a psychedelic brew known as ayahuasca. The promoters of ayahuasca drug use in churches claim it will give spiritual enlightenment and bring the user closer to God.

The government of New Mexico has allowed the ayahuasca church the right to use the drug as a sacrament even though the main ingredient is illegal under U.S. federal law. In Oregon, a U.S. District Court ruled that a church is free from prosecution for the use of ayahuasca because of the Religious Freedom Restoration Act. The Hummingbird Church, with locations in California and Utah, regularly conducts ayahuasca services.

Ayahuasca came to the U.S. from South America, where it has been used in religious rituals for many years. It is usually consumed as a tea. The active ingredient is N,N-Dimethyltryptamine (DMT), with harmala alkaloids added to prevent the hallucinogenic drug from breaking down in the digestive system.

The risk factor for ayahuasca is very high and similar to the LSD craze. It raises the heart rate and blood pressure. Many users experience seizures, and most lose muscle coordination resulting in falls. Respiratory arrests have happened, especially with people who have had the COVID virus. One complication is HPPD (hallucinogen persisting perception disorder), which, along with persistent psychosis, results in flashbacks long after discontinued use. New data also links serotonin syndrome disorder to the drug.

With ayahuasca drug use in churches in the United States, we can expect it to become more widely distributed. In addition, we can expect to see use among high school and college kids, especially those who have rejected their parent’s church and Christianity in general.

A person who throws God out of their life will desperately seek something to fill the void. Ayahuasca, like LSD, is a bad choice. The body of a Christian is the dwelling place for God’s Spirit (1 Corinthians 3:16-17), and any attempt to find a substitute is destined to fail. Ayahuasca drug use in churches and on the street will bring pain and, ultimately, death to the user. Worse than death, eternal separation from God is the ultimate tragedy for any human being.

Design of Sunflowers for Optimum Pollination

Design of Sunflowers for Optimum Pollination

Everyone knows that sunflower heads turn to follow the Sun throughout the day, allowing them to get the maximum amount of sunlight. However, researchers have found another feature that helps sunflowers to thrive. Plant biologists at the University of California, Davis, have published a report showing the incredible design of sunflowers for optimum pollination.

The sunflower head has hundreds of tiny florets. The newest florets are at the center of the bloom, and the most mature are at the edges. Their design forms a distinctive spiral pattern from the center to the edge. Each floret blooms over two days. On the first day, the male part of the bloom opens, presenting pollen. The female stigma unfolds to receive the pollen on the second day. In some way, the florets coordinate their opening, beginning at the edge and moving toward the center. This progressive opening leaves a ring of female flowers outside the earlier stage of pollen-bearing males.

Pollinating insects (primarily bees) tend to land on the edges and walk toward the center. In that way, they pick up pollen after they have walked over the female florets. Then they carry the pollen to a different flower head for cross-pollination. This coordinated opening design attracts as many insects as possible and makes pollination as efficient as possible.

The sunflower’s circadian rhythm, influenced by sunlight, controls the opening of the sunflower’s florets. People, animals, and plants have a built-in circadian clock as part of our design. We see it in the design of sunflowers for optimum pollination.

Understanding how to develop plant cultivars that can optimize pollination is essential since the bee population has been declining. We have much to learn about God’s design in the plant and insect world. Studies like this can help us meet the food shortages affecting many people on this planet.

Bugs and Cars Colliding

Bugs and Cars Colliding

When I go on a summer road trip, I always return with hundreds of insects smashed on the front of my car. Those bug remains are a real challenge to remove. So why don’t those little critters have enough brains to get out of the way? Bugs and cars colliding is a great summertime nuisance.

Okay, I know those insects that lost their lives playing a game of chicken with my vehicle don’t have very big brains – if they have any at all. I also realize that my car is much bigger than they are and probably traveling at a faster speed, so it’s hard for them to get out of the way. I also realize that the consequences of our brief encounter are much more tragic for them than it is for me. But I have never seen two bugs crashing into each other in mid-air. They can swarm in great numbers and never crash and fall from the sky. They must have some kind of collision avoidance system.

God gave insects the ability to avoid collisions with each other long before cars entered the scene. That fact led scientists at Penn State University to do some research on bugs and cars colliding. They probably can’t do much to give bugs the ability to avoid cars, but they wanted to give cars the ability to avoid hitting each other. Since bugs somehow avoid mid-air collisions with such skill, can their technology be applied to cars?

Even though only a fourth of driving occurs in the dark, half of all traffic fatalities happen at night. (It’s also when many insect species are most active, but that’s beside the point.) Present vehicle technologies for avoiding collisions use Light Detection and Ranging (LiDAR) or image sensors running sophisticated software. The systems are expensive and use lots of energy. The researchers wrote, “…task-specific obstacle avoidance algorithms allow insects to reap substantial benefits in terms of size and energy.” They wanted to learn how the bugs do it with tiny brains and micro-energy.

We have often talked about how scientists studying God’s creatures and creation have discovered ways to accomplish tasks more effectively and efficiently. For example, this new research shows ways to avoid vehicle collisions in a simpler, less expensive, and more energy-efficient way using a new algorithm based on the neural circuits of bugs.

God told Job, “If you want to learn, then go and ask the wild animals and the birds, the flowers and the fish. Any of them can tell you what the Lord has done” (Job 12:7-9 CEV). This research may not solve the problem of bugs and cars colliding, but it can help to solve the much more dangerous problem of cars colliding with other cars. Of course, you will still have to keep the scrub brush and bucket of cleanser handy.

Venomous or Poisonous – What’s the Difference?

Harlequin Poison Dart Frog - Venomous or Poisonous – What’s the Difference?
Harlequin Poison Dart Frog

People often think of venom or poison as the same thing, but they are not. Even though people may use those terms interchangeably, there are differences in their origin, delivery system, and effects on the body. So, when is it correct to say that something is venomous or poisonous?

Venom is a toxin produced by animals, usually in specialized glands. It’s delivered to the victim through a bite or a sting. Animals use venom to capture prey and for defense from predators – and sometimes humans. For example, snakes, spiders, scorpions, and some species of fish, frogs, and insects produce venom. Venomous animals have specialized structures, such as fangs or stingers to deliver the venom into the victim’s body. The effects vary from mild pain and swelling to severe muscle paralysis and even death.

In contrast to venom, poison is a toxic chemical produced by plants, animals, fungi, microorganisms, or humans in a chemical lab. Poison is usually ingested, inhaled, or absorbed through the skin. For example, many plants produce poisons to protect themselves from herbivores and other potential threats. Poisonous mushrooms, toxic berries, and certain types of flowers are examples of plants that produce poisons.

The effects of poison can depend on the type and amount consumed. Some common effects include nausea, vomiting, dizziness, and even death. Many everyday household items are poisonous and must be secured so children or animals can’t ingest them. Medicines that promote healing or fight disease are often poisonous if taken in the wrong quantities or in the wrong way.

So, if someone talks about a poisonous snake or scorpion, they are using the wrong term. Those animals are venomous. Poison does its damage when ingested, inhaled, or touched. For example, a poison dart frog is poisonous, but wasps, spiders, and snakes can be venomous. Some animals or insects are poisonous if eaten but venomous if they bite or sting. Monarch butterflies are mildly poisonous to potential predators, but box jellyfish are highly venomous and deadly to humans. If in doubt, the word “toxic” covers both, but it’s not as precise.

When saying that an animal is venomous or poisonous, remember this. A poisonous animal, such as a poison dart frog, is always poisonous and does not choose to be. A venomous animal, such as a snake, must choose to administer the venom. Humans can choose to avoid poison, but often they do not. People can take poison by mouth or inject it into themselves or someone else. We call that foolishness or murder. Alcohol is a poison that people consume as a drink, sometimes resulting in death. Self-inflicted poisoning by illegal drugs such as fentanyl is causing many deaths in the United States.

Some people ask, “Why would a good God create venomous or poisonous animals?” There is a good reason because those toxins serve as a defense mechanism or a method to capture prey for food. The more troubling question is, “Why would intelligent humans choose to put poisons into their bodies?” When asking that question, remember that it all started with Adam and Eve. “And the Lord God commanded the man, saying, ‘Of every tree of the garden you may freely eat; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die’” (Genesis 2:16-17). The good news is that God provided the cure for the poison of sin. “For the wages of sin is death, but the gift of God is eternal life through Jesus Christ our Lord” (Romans 6:23).

Mountain Chickadee Brains

Mountain Chickadee Brains

One interesting scientific question is whether brain cells can be increased or replenished. People say the brain is the only body part where the cells are not replaced every seven years. That seems reasonable since replacing brain cells could cause us to lose stored memories. Doctors are limited in what they can do to help people with brain injuries because of the inability to repair or replace brain cells. Scientists have found some interesting facts in a recent study of mountain chickadee brains.

The study at the University of Nevada has shown that brains can change when environmental factors demand it. Researchers comparing the brains of chickadees separated by a few kilometers in the Sierra Nevada Mountains found substantial differences in the brains of the two populations. Chickadees living at an elevation of 7800 feet showed significant brain differences compared to those living at 5900 feet. The hippocampus of the higher-elevation chickadees was larger, and the neuron density was greater. Tests showed enhanced spatial cognition at higher elevations, so caching and recovering food will be better for the higher mountain chickadee brains.

If you assume that both populations of chickadees came from a common ancestor, then brain development genetic change has been catalyzed by environmental factors. For example, a greater need for food caching and recall has led to physical changes in mountain chickadee brains.

The question is, could we apply this to humans with brain injuries? Is the brain designed to allow this kind of change? The brains of chickadees living in the harshest environment must develop better spatial memory to survive. Does this mean human intelligence can be affected by life challenges and environments? We need to point out that intelligence is not necessarily related to brain size because a bigger brain does not mean you are more intelligent.

Studies like this demonstrate the flexibility God designed into the DNA of living things. So maybe being called a “bird brain” is not as derogatory as people previously thought.

Echidnas Are Extremely Sensitive to Heat

Echidnas Are Extremely Sensitive to Heat

One of the most curious animals on our planet is the short-beaked echidna found in Australia, Tasmania, and New Guinea. This animal is a monotreme, a mammal that lays eggs. The echidna and the duckbill platypus are the best-known animals in this grouping. Echidnas eat ants, so they are also known as spiny anteaters. What you probably don’t know is that echidnas are extremely sensitive to heat. 

An echidna’s body temperature is normally 38 degrees Celsius (100.4 degrees Fahrenheit). If the environmental temperature hits 35 degrees Celsius (95 degrees Fahrenheit), it can be fatal for echidnas. This may sound like an impossible situation since Australia can be very hot, especially in the Dryandra Woodland and Boyagin Nature Reserve. That is where a large echidna population lives about 170 km (105 miles) south of Perth. 

Research published in Biology Letters studied 124 echidnas to see how the animals could handle the heat since they can’t dissipate it by panting, sweating, or licking. The researchers found that echidnas blow bubbles from their noses. The bubbles burst and wet the nose tip. As the moisture evaporates, it cools the animal. The evaporation of water at 100.4 degrees Fahrenheit removes 540 calories per gram of water evaporated. Even though echidnas are extremely sensitive to heat, evaporation protects them from injury.

In addition to the bubble-blowing snout, echidnas have quills to protect them from predators. The echidna’s unique design is very difficult to explain by chance evolution. Instead, God has designed creatures to survive as they deal with the varied conditions around the planet. Everywhere we look, we see that a wonder-working hand has gone before.

What is a Fetus According to Science?

What is a Fetus According to Science?

One of the most distressing aspects of the abortion debate is the refusal of the press to address scientific facts. What is a fetus? According to Dr. Michael Egnor, Professor of Neurosurgery and Pediatrics at State University of New York, Stony Brook, there are three choices scientifically: 

  1. It is a part of the mother’s body.
  2. It is not a part of the mother’s body but an individual of another species. 
  3. It is not any kind of living thing but just a clump of biological molecules undergoing chemical reactions

So, then what is a fetus?

If you accept # 1, then all pregnant women are chromosome mosaics with two sets of genomes. That means that 50% of all pregnant women are hermaphrodites having both male and female tissue. If the new life begins with a piece of the mother’s body becoming a new organism, that would be called “budding.” Budding is a form of asexual reproduction used by some species of worms, sponges, corals, and microorganisms. That is not a means of human reproduction. The fetus is not a part of the mother’s body, which is why women experience morning sickness. Her immune system is trying to reject something that is not a part of her body. 

If you accept # 2, then the fetus is a parasitic disease. The transition of this non-human parasite into a human being would be an example of speciation. You would have to call the fetus “Homo-fetus” as it evolves into homo sapiens.

If you accept #3 and say that a fetus is just a clump of biological molecules undergoing chemical reactions, then each pregnancy is an “origin of life” event. It is non-living matter transforming into life. 

Dr. Egnor says that all three of those options are “scientific nonsense.” What is a fetus according to science? He says that the scientific fact is that human life begins when the sperm fertilizes the egg. He concludes his article by saying, “The term’ person’ is a moral and legal category, not a scientific category, and it is a category open to moral discussion and debate. But “human being” is a scientific term, and it is not open to debate. The science is settled. Human life begins at fertilization, and cogent moral reasoning about abortion must begin with that scientific fact.” 

The bottom line is that humanity must decide whether or not it is acceptable to kill a human being who is a burden. We are going down a dangerous and destructive road when we avoid the scientific evidence and the biblical view of the value of human life. Whatever argument someone can make for abortion can also be used to justify the termination of those who are disabled, mentally ill, or too old to function without assistance.

A Grass Called Wheat and the Bread of Life

A Grass Called Wheat and the Bread of Life

The cultivation of a grass called wheat (Triticum aestivum) reaches far back into history. That grass became one of the first domesticated food crops and has been a primary staple food for people ever since. Today, wheat is grown on more land area than any other commercial crop and continues to be an essential food grain source for people. As a result, world trade in wheat is higher than for all other crops combined.

Although small, a wheat kernel has three main parts that enable it to feed the world. The source of white flour comes from the endosperm, which makes up about 83% of the kernel. Bran is the outer coat of the kernel, making up about 14%, and provides an excellent source of fiber. The smallest part of the kernel is the germ. It makes up only about 2.5% of the kernel and stores the embryo. People who mill flour separate the germ from other parts of the wheat kernel because it contains fat that limits flour’s shelf-life.

The endosperm of the wheat kernel contains a protein called gluten. It allows bread dough to rise by trapping minute bubbles of carbon dioxide when fermentation occurs in the leavened dough. Unfortunately, a small segment of the world’s population has to avoid eating gluten because of gluten sensitivity or a more serious autoimmune disorder known as coeliac disease. However, wheat is the most nourishing of the cereal grains, containing vitamins, minerals, carbohydrates, and fats to make a highly nutritious combination.

The grass called wheat is mentioned many times in the Bible, from Genesis to Revelation. Jesus referred to wheat in His parables and used it to illustrate principles in other ways. For example, people use wheat to make bread, and Jesus referred to himself as the Bread of Life. For thousands of years, wheat has been a vital part of the human diet, and the need for it only becomes greater as the population grows. Likewise, people worldwide need Jesus, the Bread of Life, who can teach us how to live in peace, give us meaning and purpose in life, and bring us into a relationship with God.

Why Would a Good God Create Viruses?

Why Would a Good God Create Viruses?

Think of the many illnesses that viruses cause, such as rabies, polio, Ebola, measles, mumps, yellow fever, influenza, HIV, chicken pox, hepatitis, shingles, rabies, and, of course, COVID. That is only a partial list. Some skeptics use this as an argument against the existence of God. Why would a good God create viruses?

Viruses are diverse and abundant beyond what we can imagine. The truth is that life on Earth could not exist without them. Even though many of them cause harm, they are essential tools in God’s construction of life.

By the usual definition of life, viruses are not alive since they cannot reproduce on their own. Instead, they must enter a living cell and coopt its replication functions to produce more of themselves. First, they hijack the 3D-printing machinery of the cell that turns genetic information into proteins. Then they damage the cell as they break out and spread to other cells. At least, that’s what happens in the case of the diseases mentioned. In COVID, the damage is to the victim’s respiratory tissue cells. So, why would a good God create viruses?

Viruses are present in every species of living creatures. They can be considered parasites, but sometimes they are in a symbiotic, or mutually beneficial, relationship with their host. They may remain dormant or even contribute to adaptive benefits. Problems often arise when a virus from one species enters another species. That is what happened with COVID and many other viral diseases. Most of them are known to have come into the human population from animals.

Scientists have only recently discovered that some viruses serve as food for certain microbes. They found that a single-celled microbe in the genus Hateria can live and grow on a virus diet, eating up to a million viruses per day. In turn, microbes are eaten by larger plankton which are consumed by larger predators which find their way into the stomachs of ever larger creatures going up the food chain to sustain life.

In addition to viruses contributing adaptive benefits to their hosts and providing food for microbes, they also serve other ecological roles. For example, some viruses infect algae. Algae blooms harm marine life, but the invading viruses help to control these aquatic algae blooms. Scientists have also found that viruses have contributed genes to human DNA that assist in embryonic development and help us resist infections and even fight off cancer.

So there are answers to the skeptic’s challenge, “Why would a good God create viruses?” Viruses are not evil, but they are a reflection of the design of the world in which we live. Their complexity allows them to shape and mold every aspect of the design of life.
