Life in Balance is Good

When God created and populated the Earth, he ensured everything was balanced. Genesis 1 describes the creation. After referencing the formation of life forms in verse 24, verse 25 concludes with “..and God saw that it was good.” Verses 26-31 describe the creation of humans and their relationship to vegetation and animal life. The chapter concludes by saying, “And God saw everything that He had made, and behold, it was VERY good.” God’s design in the natural world keeps life in balance.

Herbivores eat plants, keeping them in balance by spreading the seeds for more plants to grow. Carnivores keep the herbivore life in balance by feeding on the weak and old ones, preventing plants from being over-eaten. This simplified description of balance is evident in wild places worldwide. We have too often seen humans upset that balance. Selfishness, greed, ignorance, and power struggles have contaminated what was “very good” when God turned it over to humans to care for (Genesis 2:15).

Natural life in balance is excellent evidence of God’s design and wisdom in the creation. We can see what happens when humans upset that balance in these examples:

1) In the 1980s, Pablo Escobar, a Columbian drug lord, brought four hippos into the ecosystem. With no predators to control them, that number is 130 in 2024 and estimated to become 1400 by 2034. The estimated cost of removing the hippos is some 24 million dollars. With no natural enemies, the hippos have become a hazard to the people of Columbia.

2) In 1946, Argentina imported ten breeding pairs of beavers from North America, hoping to establish a fur industry. There are now roughly 100,000 beavers in Argentina, and they have decimated the native trees and built dams that have flooded forests and killed many native animal species.

3) In the 1970s, having a pet Burmese python was popular in Florida and became a raging business in Miami. When Hurricane Andrew ripped through Florida in 1992, hundreds of Burmese pythons escaped a reptile breeding facility. Today, tens of thousands of these snakes inhabit the Everglades. They can reach 20 feet long, weigh 200 pounds, eat just about anything, and spread parasites

These are just three examples of what happens when humans upset the balance that God built into the ecosystems of planet Earth. Finding a way to return the planet to life in balance as God made it is a massive challenge to biologists and wildlife managers. Human knowledge and understanding are very limited compared to God’s creative wisdom, which we see everywhere. To deny God’s existence and design requires more faith than any religious belief system.

Reproductive System of Victoria Waterlilies

Yesterday, we looked at the amazing design and structure of Victoria amazonica waterlilies. Named after Queen Victoria of England and the Amazon River where they grow, the huge leaves of these plants are amazing, and their flowers are beautiful. However, I think the most impressive is the reproductive system of Victoria waterlilies.

We have to call this a system because it involves a particular beetle species and several steps. The flowers of this plant last about 48 hours, changing from white to pink and from female to male.

On the first day, all the flowers of a single patch open at the same time. They are white female flowers that present a sweet, fruity fragrance that attracts scarab beetles of the genus Cyclocephala. When darkness falls, the flowers stop producing the scent and close, trapping the beetles inside. The beetles transfer pollen picked up from a previously visited flower.

On the second day, the flowers receive anthocyanins turning them pink to show that they have been pollinated. As the flowers remain closed, the beetles are treated to a starchy and spongy treat that nourishes them. The flowers then open to release the beetles, and the stamens of the now male flower deposit pollen on the beetle. The flower then closes and descends below the water while the beetle carries the pollen to a white flower in another location, where the process repeats.

This reproductive system of Victoria waterlilies cross-pollinates the plants while preventing self-pollination, as the flowers are female one day and male the next. The beetles are treated to nourishment as they carry out the pollination. The system depends on a plant species and a beetle species working together according to a timed sequence. Could this have happened by an accident of evolution, or does it show design? We think design is the best explanation, and design demands a Designer.

Design and Structure of Victoria Waterlilies

If you were going to build a barrier between the atmosphere and the water in a pond or lake, what material would you use, and how would you construct it? The construction industry would probably use concrete or iron. The problem with these materials is that they are vulnerable to chemical degradation and changes in temperature. In recent years, we have seen bridges collapse after relatively short periods of existence. Bridge design is difficult because the atmosphere presents a different set of problems than those encountered in the underwater world. God has an answer to this issue, which we can see in looking at the design and structure of Victoria waterlilies.

In the Amazon River, the leaves of the Victoria amazonica waterlily can grow to 10 feet in diameter. These lilies have very large, flat green leaves that grow on the surface of the water. The submerged stalk can grow to 26 feet long at an inch per hour. For protection from underwater herbivores, the salk and leaf bottoms are covered with numerous small spines.

The very large leaves have a network of veins underneath that some have compared to “transverse girders and supports.” This lattice-like structure under the leaves allows the plant to hold air, giving the leaf great strength and buoyancy. If the weight is evenly distributed across one leaf, it can support hundreds of pounds.

Many times, people have copied the amazing designs we see in the natural world, and Victoria water lilies may be one example. You can see them in many botanical gardens in the United States and other countries. Everywhere we look, we see the wisdom and design of God in His creation. However, the most amazing thing about the Victoria amazonica waterlily is the system it uses to reproduce. We will look at that tomorrow.

Effects of THC on the Human Brain

The human brain is the most complex computer in the world. In one study trying to understand brain health and disease, scientists identified 3,313 different types of neurons in the brain, but there is much more to learn. Other studies have examined the effects of THC on the human brain. THC is the primary psychoactive chemical in marijuana (cannabis) plants.

One study of teen health in Australia and New Zealand dealt with the effects of THC on the human brain regarding depression and suicide. It showed that adolescents using cannabis were 2.5 times as likely to have depression and three times as likely to have suicidal ideas than those who did not use cannabis.

A study of adults who used cannabis daily showed there was five times the risk of psychosis compared to non-users. A Canadian study has shown that emergency department visits for cannabis syndrome increased by a factor of 13 between 2014 and 2021. Despite today’s concentrated cannabis products, science does not fully understand the effects of THC on the human brain, so users have become the test subjects.

Humans have long used breeding to increase desirable features in animals, such as dogs, and plants, such as corn. They have used the same methods on marijuana plants to increase the content of THC. The result is that today’s marijuana has a much more potent effect on the human brain. In 1995, the total THC by weight of marijuana was around 4%. Today it is 20% or more. Concentrated cannabis products can have THC content as high as 95%. Teen exposure to THC can lead to long-lasting problems with memory and learning. Use by teens is more likely to lead to addiction than adult use, and cannabis addiction is linked to schizophrenia.

Recreational drug use has a long history, but there is very little research available on the long-term effects of cannabis and the effects of THC on the human brain. The Christian concept of the human body as the dwelling place for God’s Spirit (1 Corinthians 3:16) advises against activities that harm our health. God speaks to us in verse 17, saying that if anyone defiles the temple of God (our body), there will be severe consequences. We are seeing that promise carried out in the adverse effects of cannabis use.

How a Delicate Root Can Penetrate Hard Rock

We have all seen plants growing through cracks in concrete or bedrock and wondered how a delicate root can penetrate hard rock. Recent research has shown that the root jackhammer process is highly complex.

In a paper published in the journal Current Biology, a group of researchers discovered some of the secrets of how a delicate root can penetrate hard rock. For one thing, the optimum angle for the root tip to attack is 90 degrees. Striking the hard object at a different angle could cause the root to deflect. A protein called OsAUX1 keeps the root tip pointed down.

Another way that roots are similar to a jackhammer is that the root hairs provide an anchor for the root, and OsAUX1 causes more root hairs to grow. If you have ever seen a worker using a jackhammer, you know that someone has to hold it tight, or it will bounce on the material’s surface instead of penetrating.

Another protein that helps explain how a delicate root can penetrate hard rock is PIEZO1. If the root continued to grow quickly when it contacts a rigid material, it would likely bend or break. PIEZO1 signals the root to slow down when it encounters a hard barrier. This “touch-sensitive” protein shows more engineering involved in root growth. In all, 14 proteins, plus genes, promoters, hormones, and tissues enable roots to perform their amazing stunts.

The importance of this design is Earth-shattering, or should we say rock-shattering. It explains how soil is produced in an area where rock dominates Earth’s surface, as in a lava flow or an intrusive rock like granite. The process is like a jackhammer in which root caps use weaknesses in the host rock to penetrate and break the rock into smaller pieces so plants can secure the nutrients they need.

Some plants in unusual environments don’t use roots in the same way. Plants living in ocean environments or along sand bars, such as mangroves, have a different process to sustain themselves. Air ferns and epiphytes don’t have the same kind of root system as a maple tree. The diversity of plant life and how each type of plant handles its environment is a great testimony to design and the wisdom of the Creator.

Protecting Parasites from Extinction

We tend to view parasites as destructive, even repulsive, unwanted nuisances. However, scientists are finding that parasites often perform beneficial roles in the ecosystem. Some scientists think we should be protecting parasites from extinction.

Scientists are concerned that we have not studied the roles of parasites in maintaining a balanced ecosystem. For example, a parasite known as Toxoplasma gondii infects mice, causing them to lose their fear of cats. Cats have an acid in their gut that Toxoplasma gondii needs to reproduce, so the mouse is an intermediate host for the parasite to get into the cat. This appears to be a highly designed system in which a parasite controls the mouse population through cats.

Kayce Bell of the Los Angeles County Natural History Museum said, “If you remove something from an ecosystem, we cannot foresee what the consequences will be.” That is true of familiar plants and animals but may also be true of parasites. Moreover, it seems that some parasites keep other parasites under control. In 2020, scientists who study parasites published a paper in the journal Biological Conservation calling for protecting parasites from extinction, beginning with a study of what parasites exist.

Scientists estimate that 40% of all known animal species on Earth are parasites. The bottom line is that we don’t understand the role parasites play in the natural world. The fact that we don’t know what beneficial things parasites do is a challenge as we struggle to conserve ecosystems worldwide. Everywhere we look, we see a system design that testifies to a Designer.

Trees Are Affected by Smoke

Smoke from wildfires has been a fact of life for virtually everyone. Even here in Michigan, we have seen smoke from the fires on the West Coast. At times, it has been dense enough that some folks with respiratory illnesses have had to stay inside and use air purifiers to breathe. Researchers at Colorado State University have found that even trees are affected by smoke, but they have a system designed into them to avoid damage that smoke can cause.

Plants have pores called stomata on their leaves, which do the opposite of our lungs by taking in carbon dioxide and expelling oxygen. However, taking in smoke could interfere with this process. The researchers found that when smoke wafted across ponderosa pines, the trees responded by closing their stomata, essentially holding their breath.

Smoke in the air is not a new feature in the natural world. Fires are expected whenever there are forests and dry weather, even without human carelessness. Since trees are affected by smoke, they have a designed response to what might damage their ability to take in carbon dioxide. This is just one more example of the incredible thought and planning that went into the creation.

Genesis 1:11-12 tells us that God created the fruit tree, but as we look deeper into the makeup of trees, we see the handiwork of God displayed in this remarkable design. Research is ongoing to see if this is true of all plants, including those we depend on for food. This question becomes very important with the increase in wildfires in the past two years.

“Plant Neuroscientists” and Plant Consciousness

“Plant Neuroscientists” Claim Plant Consciousness

Several “plant neuroscientists” have written papers claiming that plants have intelligence and cognition and experience pain and other feelings. This is not the work of crackpots but of reputable scientists writing in professional journals.

It started in 2006 with an article in the scientific journal Trends in Plant Science by E.D. Brenner titled “Plant Neurobiology: An Integrated View of Plant Signaling.” In 2009, Frantisek Baluska claimed that root tips were “a brain-like command center.” In 2016, Monica Gagliano claimed to have demonstrated Pavlov-type classical conditioning in pea plants. The following year, she wrote that plants have an “internal value system” and use “feelings” to “motivate their choices.”

Plant neuroscientists accuse scientists who reject their claims of being “animal chauvinists.” The reality is that if you reject eating plants because they have feelings and experience pain, you will also have to reject eating insects or animals of any kind, such as fish, birds, or even farm animals. That leaves you with nothing to eat.

Genesis 1:29 finds God telling Adam and Eve, “I have given you every herb bearing seed … and every tree in which there is fruit for food.” In Genesis 9:3, God told Noah, “Every moving thing that lives shall be food for you even as the green plant I have given you.” God gave humans the capacity to have adequate food and challenged us to manage His environment with intelligence and respect.

Scientific evidence shows that what plant neuroscientists interpret as consciousness is a misunderstanding of the design God built into plants. It is well known that sunflower blooms will turn to follow the Sun from sunrise to sunset. Are the sunflowers thinking and acting on their thoughts? Of course not! This function is programmed into the plants to give them maximum sunlight exposure.

We have all seen plants wilt when they are too dry or hot. Is this the result of feeling pain or thinking out the need to reduce leaf area? An intelligent Creator hard-wired these responses into their DNA. Animals have consciousness because of a complex nervous system and a brain system that oversees the neural pathways. Conscious responses to pain help animals and humans survive.

I have known people who talk to their plants and claim that it makes the plants grow better. I must admit that I have talked to my car when it wasn’t working. Whether plants or cars, our conversations are really for our own benefit, not the thing we are taking to. We tend to anthropomorphize plants and cars, giving them human attributes. God has designed plants to feed us, shade us, and show us beauty, but they are not created like us and are not to be worshipped.

The Giant Sequoia Design

The design that God has built into every ecosystem continues to radiate the truth of the biblical statement that we can know there is a God through the things He has made (Romans 1:20). As science discovers design in the creation, the truth of that biblical statement becomes obvious. We often see design in very small things such as bacteria, viruses, and algae, but on the other end of the scale, we find very large objects such as the giant sequoia.

Imagine a plant that can be uninjured by fire but needs fire to reproduce. In our day of forest mismanagement resulting in massive fires, this feature becomes important. In the past, smaller fires wiped out ordinary trees like oaks or maples. The super-large trees were unaffected by the fires and used them as part of their reproductive design. One of the most notable examples is the giant sequoia found in California.

The giant sequoia is so tall and large that fire does not affect it. The tree stands more than 370 feet tall. (A football field is 300 feet long.) Giant sequoias weigh 640 tons, as much as 107 elephants. They can be up to 29 feet wide and are not affected by the blights that affect ash, elm, oak, or maple trees. In California, the redwoods cover 1.6 million acres, and the giant sequoias another 48,000 acres. These trees, which do not depend on groundwater and a root system, get their moisture from snow, rain, and fog.

These giant trees occupy a unique ecological niche among Earth’s staggering diversity of plant and animal life. They show God’s design and planning, making our planet extraordinary.

Tumbleweed Life

One of the most ingenious methods of spreading seeds in the natural world is the design and function of the tumbleweed. These plants exist in dry places where there is a lot of wind. The tumbleweed life is challenging.

The tumbleweed design deals with two big problems. The first is that the plant must be structured so that the part of the plant with the seeds has a low mass so the wind can move it. The second requirement is that the framework holding the seeds must be designed to attach to something in a place where the seeds can germinate.

If you have been around tumbleweeds, you know not to grab them or allow them to bump into you. The tumbleweed’s framework is covered with sharp edges, so once it strikes something, it stays put until the seeds are dispersed and the rainy season has started.

The typical design of plants involves seeds or roots being planted in soil and drawing nourishment to produce leaves, blooms, and fruit. In arid desert areas, fertile soil is a rarity, yet tumbleweeds, with their unique design, continue to thrive, overcoming this significant challenge.

In human relationships, we can draw a parallel. Some people live a tumbleweed life with sharp edges and no roots. They exist in empty spaces, hurting anyone they touch. This destructive nature of a ‘tumbleweed life’ underscores the importance of being rooted in the positive values of Christ and His teachings. Not putting down roots is a sure way to tumble, and rooting oneself in Christ can provide the stability and the best that life has to offer.
