Beavers Can Help Reduce a Climate Change Problem

People here in Michigan consider beavers a nuisance because they cut down trees and flood farmlands. Unfortunately, beavers cut down some beautiful shade trees on our property. However, beavers can help reduce a climate change problem.

A significant problem associated with the changing climate is the loss of water. Many reservoirs in the western United States are at extremely low levels, and some have completely dried up. Precipitation amounts have dropped while humans mismanage natural water storage.

Meanwhile, people have hunted and trapped beavers due to high prices for pelts and the flooding of farmland and private homes by the dams they built. The result is that water now floods downstream areas. Beavers reduce that problem by creating ponds that hold the water, so it runs off much more slowly. Besides reducing flooding, this also helps to minimize droughts. Studies funded by the National Science Foundation show that by live trapping and moving them upstream, beavers can help reduce a climate change problem.

God has provided ways to make climate change less damaging. For example, storing water in snow and glaciers helps mitigate the problem of water distribution. Additionally, beavers can reduce the problem by building dams that hold water back, providing relief from weather extremes.

God has given us the responsibility of managing what He has created. However, by creating pollution and mismanaging natural resources such as beavers, we have created problems we can no longer ignore. We can all participate in caring for the creation, and pleading ignorance won’t stop the damage.

Designing a Planet to Support Life

An interesting electronic game is one where you have access to a reservoir of materials to design a life-sustaining planet. Once you choose your materials and processes, the game computes how long life could survive on your planet. All the choices end up sterile, but the player with the longest survival time is the winner. Unfortunately, the limited number of variables causes all the options to eventually result in a lifeless globe because designing a planet to support life is a complex process.

As scientists examine systems that support life on Earth, they find multiple complex systems with some surprising agents that allow life to exist over the long haul. For example, we have written before about how many bird and mammal species spread seeds. Also, ants spread the seeds of more than 11,000 plant species. Without ants, the existence and abundance of many plant species could be impossible. A recent study has shown that other insects also spread seeds, allowing the enormous number of plant species on Earth.

Most plants have a compound called “herbivore induced plant volatiles” (HIPVs for short). A plant releases these HIPVs when caterpillars start eating its leaves. The HIPVs attract hungry predators that eat caterpillars. A recent study showed that agarwood (Aquilaria sinensis ), which is native to China, depends on hornets to spread its seeds.

Agarwood fruit produces HIPVs even though it is not assaulted by caterpillars. The agarwood HIPVs attract hornets which rush to capture the plant’s seeds. The hornets carry the seeds to their nests, where they eat the fleshy nutrient-rich structures called elaiosomes attached to the seeds. The hornets discard the seeds on the ground near their shaded nests. The seeds would dry out and die in the sun, but they germinate to produce new agarwood plants in the shade.

The Chinese people use agarwood for various purposes. However, the plant is listed as “vulnerable” because of habitat loss and the fact that local people eat the hornet larvae. Designing a planet to support life is a complex and challenging goal only God can do. Unfortunately, humans lack the wisdom to protect the life-sustaining system God has created for us.

Blood Moon and Shooting Stars

On the morning of November 8, you will have a chance to see a total lunar eclipse, also known as a “blood moon.” At the same, you may also see a display of “shooting stars.”

A full moon occurs every 29.5 days as our planet comes between the Moon and the Sun. A couple of times per year, the alignment is precise enough that some part of Earth’s shadow falls on the Moon. If the outer area of the shadow crosses the Moon, we see a slight darkening of the Moon’s light. If the full shadow covers only a portion of the Moon, we see a partial eclipse looking as if someone has taken a bite out of the Moon. However, we will see the more dramatic total lunar eclipse this time.

When the eclipse reaches totality, the Moon will take on an orange or reddish glow. That is why people call it a “blood moon.” That color is because the small amount of sunlight reaching the Moon’s surface is the glow of sunrise and sunset all around the world. Our atmosphere bends and filters the light, blocking the blue light and focusing the lower-frequency reds and yellows on the Moon. We see that reflected back to us, this time for about 85 minutes.

You can enjoy a double treat if the sky is clear and the weather is not too cold. This is also the time for the annual Taurid meteor shower. The annual Taurid “shooting stars” are actually fragments of the comet Encke which burn up from the friction of Earth’s atmosphere. They are primarily tiny sand-grain-size pieces of rock that appear as streaks of light. However, some may be a little larger, looking like fireballs. The Taurids generally move more slowly and are often larger than the meteorites of other annual meteor showers. But, they may be fewer and farther between, with perhaps five to fifteen per hour visible in very dark skies.

The problem this year is that the peak of the Taurids is during the full Moon. The bright Moon always makes it difficult to see the much dimmer meteor showers. However, the 85 minutes of the total lunar eclipse creates an ideal window to look for the meteorites. So you can enjoy the “blood moon” and the “shooting stars” at the same time.

So, how and when can you see them? The total eclipse phase will begin on the morning of November 8 at 5:17 a.m. and end at 6:42 a.m. Eastern Standard Time. The partial eclipse will start and end about half an hour before and after those times. The faint penumbral phase will begin and end about an hour before and after the partial eclipse times. To see the Taurids, plan on being where you can see a clear view of the whole sky during the total eclipse phase. If you miss this total lunar eclipse, the next one will not occur until March 14, 2025.

Romans 1:20 tells us that we can know there is a God by observing the things He has made. What do the lunar eclipse and the Taurid meteor shower tell us about God? They are not omens of world events. They tell us that the creation is not chaotic but predictable. We live in a solar “system” in which we can accurately predict the movement of planets and moons and calculate what is going to happen and when–even to the exact minute. God has given us an orderly universe that we can study to learn about His power and wisdom. He has also given us His written word, which we can study to learn about His love and find the instructions for how to enjoy the gifts He wants to give us.

The Grand Canyon of Pennsylvania

When you hear the name “Grand Canyon,” you usually think of Arizona. I have been to the bottom of the Arizona canyon and taken several boat trips down the Colorado River. As a result, I have nothing but good memories of that majestic canyon. Recently I had a chance to visit Pine Creek Gorge, also known as the Grand Canyon of Pennsylvania.

As a person trained in geology and an admirer of Earth’s beauty and history, I was amazed at how much I could see in this canyon. It’s 1000 feet deep and stretches for 47 miles through northern Pennsylvania. Because it is an erosional formation, it mainly consists of sedimentary rocks. Glaciers went through that flat area and created a lake. Eventually, the natural dam holding back the lake eroded, and the water escaped, gradually forming the canyon. As a result, glacial erratics made of all kinds of rocks, some as big as a house, are scattered all around the area.

The rocks that make up the Allegheny Plateau tell a history of change. Limestone layers form when water is still, and minerals can come together to produce the rock. A flood never produces limestone, and many of the limestone rocks contain marine fossils. Rapidly moving water produces gravel which becomes a rock known as conglomerate. Shale is mud turned into rock, and sandstone can be a beach deposit left by moving water or blown by the wind. None of the sandstone in the Grand Canyon of Pennsylvania is wind-blown.

The 1000-foot canyon has all of these rock types in various layers. It is evident that at times an ocean covered this area, and other times glaciers deposited boulders, cobbles, and gravel. In addition, the existence of a lake laid down some layers, and occasional coal seams tell us of ancient swamp conditions. Therefore, it is not surprising that the first oil well was produced near this area.

What do places like the Grand Canyon of Pennsylvania tell us about God? God is not a magician and does not try to deceive us. Understanding how God made the land on which we live is a testimony to His wisdom and power and the fact that time is not an issue for God. The flood of Noah cannot explain the Grand Canyon of Arizona or the Grand Canyon of Pennsylvania. We can see clear evidence of a gradual process and claiming that God miraculously zapped all of this into existence without a process over time puts God in the role of being a deliberate deceiver. Because most of these rocks are not flood deposits, neither a flood nor intentional deception is an acceptable explanation for these beautiful canyons. Science and faith are friends, and the scientific evidence of how canyons like this were formed gives evidence of the patience, design, and purposes of God.

God Spoke It Into Existence

One of the wonderful things that technology gives us is the ability to see how God created the Earth and life on it. The Webb telescope is adding to our understanding of the universe. Advances in astronomy and optical telescopes continue to give us more pictures and data, helping us understand what God has done and the methods He employed. When dealing with the creation, preachers, and even some Bible paraphrases, are fond of saying, “God spoke it into existence.” That is an oversimplification because, obviously, it was not God’s voice that created time, space, and matter-energy.

The NASA Astronomy Picture of the Day (apod.nasa.gov) for September 20, 2022, has a beautiful picture of the “Statue of Liberty Nebula.” (See the link below.) The data from this area of space shows the presence and creation of complex carbon molecules known as polycyclic aromatic hydrocarbons (PAHs). Biologists tell us that these are building blocks of life.

In addition to chemical compounds like PAHs, we can also see hydrogen being forged into the heavier elements that make up the creation around us. Hydrogen is a non-renewable resource, and as we watch stars turning it into heavier elements, we know that the process had a start. The existence of hydrogen throughout space tells us there was a beginning to the creation. As hydrogen is forged into heavier elements, the amount of hydrogen in the cosmos decreases. If space, time, and matter-energy were eternal, all of the hydrogen would be gone.

Proverbs 8 tells us that wisdom was a partner in creation. Psalms 148 praises God for the creation, and verse 5 says, “He commanded, and they were created.” That is not the same as saying, “God spoke it into existence.” As we study God’s WORD, we learn of His wisdom and love. As we study God’s WORK, modern technology allows us to know some of His methods more clearly than ever before.

The Bible gives a simple statement of creation that every human can understand: “In the beginning God created the heaven and the earth” (Genesis 1:1). Science shows us the wisdom, power, and design of what God has done.

Our Planet is Unique and Bizarre

Human technology has allowed more observations of our planet than most of us realize. NASA currently operates around 30 Earth-observing missions accumulating massive amounts of data. We know about changes in sea level for the Earth’s oceans within a fraction of an inch. Hourly, we can know the areas of our planet covered with snow. We measure the amount of tree cover on Earth and minute-by-minute changes in the planet’s atmosphere. The result of all this detecting and measuring is that we know that our planet is unique and bizarre.

Earth is the only planet we have seen with an active water cycle that causes weather and allows the recycling of water resources. It is also the only known planet with active plate tectonics, recycling minerals within Earth’s crust using earthquakes and volcanoes while releasing volatiles that create and maintain our atmosphere.

We have only recently understood the Moon’s role and how important it is for life to exist on Earth. We know that it was formed in a catastrophic impact that determined its location and size. The size and distance from Earth are precisely right to cause the strength of our tides and give our planet a stable 23.4-degree tilt. Without the Moon, our Sun would cause very weak tides causing our coastlines to be much different, while the planet’s axis of rotation would wobble, destabilizing the climate.

Our planet is unique and bizarre because it has been shaped by vegetation, responsible for the atmosphere’s oxygen content of 21%. The typical astronomical atmosphere of planets is dominated by methane and carbon dioxide. Photosynthesis uses sunlight and carbon dioxide to produce the oxygen we breathe. Science is still struggling to understand the source of the massive amount of minerals we have on Earth. Meteorites have a small number of minerals, and while the Moon has a larger number, Earth’s variety of minerals is astounding.

Discover magazine featured an article discussing NASA’s studies of planet Earth. It stated that Earth observations have taught scientists one sure thing: “Our planet is unique and bizarre, with unusual properties that don’t match those of any other world we’ve seen, either in our own solar system or beyond it.”

For those of us who understand the science involved and believe in God as the creator, this is no surprise. Proverbs 8 finds “Wisdom” saying, “The Lord possessed me in the beginning of His way …” We see that beautifully demonstrated as we look at our planet and marvel at the intelligence of the Designer who produced it.

Natural Insect Control by an Insect

People struggle with many insects that give us diseases, impact our food supply, and even damage our clothing. Mosquitoes, locusts, grasshoppers, cockroaches, crickets, and the like have been a scourge prompting the use of pesticides. The pesticides, in turn, have brought cancer and attacks on our immune systems. Yet, we often overlook the fact that God has given us natural insect control by providing agents that eat insects, including birds, bats, fish, and even insects. One insect-eating insect that looks like it came from another planet is known to entomologists as “Mantis religiosa” but is commonly called the praying mantis.

The mantis has bulging eyes and a triangular-shaped head that swivels atop a long neck, giving it an odd extraterrestrial look. It is the only insect with three-dimensional vision. It holds its two front legs at an angle as if folded in prayer while actually poised to ambush prey. Those forelegs are armed with spikes so that when they capture an insect, it cannot escape.

Humans introduced the praying mantis from Europe into New York state in 1900 to control grasshopper infestations. Mantises are voracious eaters and can even be cannibalistic. Their population is partly controlled by eating each other when the food supply becomes reduced. Females sometimes eat the males and the egg capsules when there is a food shortage.

A mistake humans have made is using chemicals to control insect populations instead of using the natural controls God has given us. Spraying massive amounts of insect-killing chemicals kills everything, including insect-eating birds, fish, and insects like the praying mantis. We often hear people blaming God for the diseases and afflictions humans have caused.

The more we study the creation, the more we see natural insect control agents. They may require work and a more significant time investment than the easy process of spraying, but they cause far less collateral damage.

Nadir Asteroid Impact Crater

One of the challenges to evolutionary theory is the principle of uniformitarianism–the assumption that no process has ever functioned on Earth that is not going on today. We are not talking about common disasters but events in Earth’s history that would have altered the course of evolution or stopped it entirely. For many years, scientists have known about the Chicxulub asteroid that struck the area that is now Mexico’s Yucatan Peninsula, probably causing the extinction of the dinosaurs. Such an event would have changed life’s future direction. Now, there is news of a Nadir asteroid impact crater.

BBC news reported that geologists discovered a possible asteroid crater off the coast of Guinea in west Africa. They call it the Nadir crater because it is at the Nadir (opposite lowest point) of the Chicxulub crater. This new crater is 8,500 meters wide and over 300 meters lower than the seabed. It is about the same age as Chicxulub but much smaller. The Chicxulub crater, caused by a larger asteroid, is 12,000 meters wide.

Both of these asteroid collisions would have violated uniformitarianism, dramatically affecting life on Earth. The Chicxulub asteroid impact would have caused major earthquakes, tsunamis, and a global firestorm. The result would have thrown enough dust into the atmosphere to plunge Earth into a deep freeze that dinosaurs could not have survived.

Since the Nadir asteroid impact crater is in an ocean environment, it would have caused a tsunami with a wall of water over 1000 meters high. The Nadir collision would have produced about 1,000 times more energy than Tonga’s recent (January 2022) volcano eruption. However, the energy from the Chicxulub impact would have been about 10 million times greater.

The textbook model of evolution is greatly simplified. We don’t fully understand how an asteroid collision would have affected life on Earth. It seems unlikely that most life forms could have survived the one-two punch of Chicxulub and Nadir asteroid impacts.

Genesis 1:1-3 indicates that there was a change in the Earth. An accurate translation of verse 2 is that Earth “became empty and wasted.” That is precisely what the asteroid collisions would have caused. This may have been God’s methodology of a final step to make Earth fit for human life. This new evidence supports the biblical account in ways we are only beginning to understand.

Soil Derived from Barren Rock

I have had the privilege of walking along a still hot lava flow in Hawaii and watching it cool and crack, exposing a red hot glowing interior. As a student of geology, I have seen the bedrock that tells of the composition of the early Earth in places throughout North and South America and England. There can be very little doubt that the creation of planet Earth left a ball of sterile, barren rock orbiting the Sun. Having lived for 85 years on this planet, I have had the joy of seeing soil derived from barren rock supporting vast plant and animal life.

The story of how soil is produced is a story of wisdom and design unique to our planet. Therefore, it is essential that we understand the importance of the soil God gave us and how to take care of it in our age of expanding populations.

National Geographic published an excellent article by Ferris Jabr titled “Out of Sight,” containing pictures by Oliver Meckes and Nicole Ottawa. The pictures show the agents God created to convert the barren rock of our planet into soil that can grow a forest. A single gram of forest soil (1/454th of a pound) can contain as many as a billion bacteria, a million fungi, hundreds of thousands of protozoa, and nearly a thousand roundworms. The pictures of those microscopic organisms are incredible.

Soil derived from barren rock began with fundamental processes caused by rain, wind, and ice. Once the elements broke down the rocks to small sizes, the microscopic living organisms went to work. Microbes, fungi, lichen, and tiny plants broke down the sand-size rocks and enriched them with minerals life could use. In Hawaii, you can see the black sand beaches produced in modern times and the places where those agents have processed soil in which plants can live. Over time, the elements in early soils, such as carbon, phosphorus, and potassium, were processed to produce advanced soil structure.

The Genesis creation account does not explain God’s methods of preparing the planet for human life. Proverbs 8:22-36 finds Wisdom narrating the processes of creation. But even Wisdom can’t describe the process of soil derived from barren rocks to people with no microscopes or technical language. Today, we are uniquely privileged to see God’s handiwork and to marvel at the incredible complexity involved in the creation of dirt.

Wildfire Aftermath and Recovery

If you are like me, you have watched with pain the terrible wildfires in the western United States. We tend to focus on the folks who have lost homes or barely got out with the clothing on their backs. However, the long-term effects of wildfires are not as bad as the human tragedy often caused by human mismanagement. Several research studies funded by the National Science Foundation have dealt with wildfire aftermath and recovery.

One study of charcoal from Wales and Poland tells the story of plants consumed by fire millions of years ago. Botanists say that instead of the grasses, trees, and flowers we see today, previous ancient land plants were under an inch tall. Some waist-high or knee-high plants existed, but much of the landscape was covered with tiny plants. At that time, the big plants were fungi that towered over all other plants. A well-preserved prototaxite fossil fungus shows that they stood 30 feet tall.

Earth’s atmosphere at that time had very little oxygen, unlike the 21% figure we see today. Fires would not occur because of the lack of oxygen. Modern studies show that a fire of any size isn’t likely below 16% atmospheric oxygen. Once the level exceeded 16%, fires occurred, and wildfire aftermath and recovery paved the way for the large plants we know today. Modern plants can generate large amounts of oxygen to sustain animal life.

In today’s wildfire aftermath and recovery, there are always “green islands” where a tree cluster avoids being burned because of the topography or nearness to water. A high percentage of seeds from these patches of unburned trees remain to germinate and grow. The creatures that would ordinarily eat the small trees are no longer there, so the plants survive to rapidly reforest the area. That means areas with “green islands” do not need human tree planting. Most human effort and resources can go to places with no “green islands.”

These studies help us understand God’s methods of preparing Earth for humans and the animals we need. Genesis 1:11-12 gives the same picture that the scientists are finding. It says that the first form of plant life was the grasses – “deshe” in Hebrew means tender grass. The second group of plants is “eseb,” meaning “naked seed,” – gymnosperms. That is followed by the tree bearing fruit containing its seed – angiosperms. The Bible tells us the order of progression from early forms of plants to the ones we depend on today. The Bible does not tell us how God did it or how long it took, but scientific research today gives us that information.
