A Rock’s Not Alive

The following came to us from our friend Dr. Phillip Eichman, who has a Ph.D. in biology.

For many years I began the courses that I taught in Fundamentals of Biology and General Biology by bringing two things to class: a rock and something living, usually a plant from the greenhouse. Most of the students had never seen me before and must have wondered why I brought those things to class. One day I surprised the students even more with a turtle that I rescued from the middle of the road. The point that I wanted to make is that there is a vast difference between a nonliving thing and a living thing. The expression “a rock’s not alive” comes from an old Sesame Street song and makes the same point.

A rock’s not alive. It is made up of the same chemical elements as the plant or the turtle, but that is where the similarity ends. Anyone who has taken a biology course will realize that even the simplest living thing has a complex organization. It is capable of taking in and using energy, growing and reproducing, and responding to the environment.

Obviously, something happened to make living things so different from nonliving matter. Either it is a big coincidence, or some higher intelligence planned and directed the formation of life on Earth. More than forty years of studying and teaching biology have convinced me that the latter of these is true. The world in which we live is not an accident, but rather the handiwork of a creator that we call God (Psalm 19:1).

Trees Can Slow Global Warming

Anyone who has read valid scientific studies must be aware that there is massive evidence that the planet is facing climate change. Politicians are proposing all kinds of elaborate and expensive solutions. The fact is that God has given us a solution that goes back to Genesis 1:11-12. “And God said, ‘Let the land produce vegetation: seed-bearing plants and trees…and God saw that it was good.’” Trees can slow global warming.

In Liuzhou, China, Italian architect and urban planner Stefano Boeri is helping to develop the world’s first “forest city.” Nearly a million plants are being used to cover parks, schools, offices, and apartments. People in Louisville, Kentucky, are working on a similar plan called The Green Heart Project, with 14.5 million dollars to plant 10,000 trees. Louisville has had some health issues with high pollution levels and high rates of cardiovascular disease. The Green Heart Project began in 2018 directed by Eruni Bhatnagar of the Christina Lee Brown Envirome Institute at the University of Louisville. Similar studies and projects are underway at Murray State University, Arizona State University, Washington University in St. Louis, St. Lawrence University, Yale, Stanford, and Johns Hopkins.

Most of us are aware that trees take in carbon dioxide and release oxygen, but the idea of planting trees and other forms of vegetation in urban areas is relatively new. In 2014, Italian developers completed the Bosco Verticale, which is Italian for vertical forest. They built a double skyscraper to hold 800 trees, 15,000 perennials, and 5,000 shrubs that spill over terraces. Dozens of studies have shown that people living near green spaces have lower stress levels, lower asthma rates, and fewer cardiovascular and respiratory tract illnesses.

When the Genesis account was written, there were no problems with carbon emissions and pollution, but even then, God was giving us a key to health. Rather than causing enormous energy costs and damaging our economy, trees can slow global warming, so let’s plant massive numbers of trees.

Stop the Killing of Bees

There are many things that God has provided that we take for granted, and yet without them, we would not be able to live on planet Earth. One example is the common bee. The Earthjustice organization has been involved in trying to stop the killing of bees, and they gave some interesting statistics.

Bees fly an average of 55,000 miles (88,000 km) to produce one pound of honey. They can see colors that humans can’t see, and they communicate by dancing. Very importantly, it’s hard to realize that one-third of our food crops are dependent on bees. It takes 60,000 bees to pollinate one acre of an orchard, and without bees, we would have no almonds, apples, apricots, squash, and many other fruits and vegetables. An average hive contains about 30,000 bees.

One problem is that every year farmers apply over 5.6 billion pounds of pesticides to our country’s crops, and that is a factor in the decline of the bee population. The current alarm over the drop in the bee population is an excellent time to remember that God provided bees, not just for honey. They also sustain the food crops we need. That is why we must stop the killing of bees.

Complex Photosynthesis and Life

Photosynthesis is a biochemical process that plants, algae, and some bacteria use to create food and release oxygen into Earth’s atmosphere. We recently pointed out even some sea slugs can use photosynthesis. Complex photosynthesis and life defy accidental explanation.

Chlorophyll is the molecule that drives the process. There are two chemical reactions–one dependent on light and one independent of light. In the light-dependent reaction, sunlight enters the plant and energizes the chlorophyll. The chlorophyll splits water into hydrogen and oxygen and feeds electrons into nearby molecules. The oxygen escapes and the hydrogen is used later. The freed electrons make a molecule called ATP, which fuels cellular functions. With more sunlight, a molecule called NADP is produced.

In the light-independent reaction, NADP combines with the freed hydrogen to make a larger molecule called NADPH. These components, NADPH, ATP, and an enzyme called RuBisCCo, create sugars and other carbohydrates using carbon dioxide and water in a complex chemical process called the Calvin-Benson cycle.

Chlorophyll uses light in the blue and red part of the spectrum, reflecting green light, which is why trees and grass are green. Photosynthesis takes carbon dioxide from the atmosphere and forms the foundation of all food chains on Earth.

We have vastly oversimplified this explanation of complex photosynthesis and life. To believe that it could have happened by chance requires profound faith in luck. Photosynthesis reflects the wisdom of the Creator, who used some incredibly complex processes to establish life on this planet.

Vaping Weed is at least as bad as Smoking Cigarettes

States across the United States are rapidly approving the recreational use of marijuana, but scientific evidence suggests this is a dangerous development. Very little research has been done on marijuana vaping, but available evidence shows that vaping weed is at least as bad as smoking cigarettes.

The United States Centers for Disease Control and Prevention have identified a new disease called EVALI. That is short for E-Vaping Associated Lung Injury. An apparent culprit in this problem is vitamin E acetate, a sticky oil substance often added to vaping products. This is especially common in vaping products that contain THC, the primary psychoactive compound in marijuana.

The Center for Disease Control says that 84% of the EVALI cases involve cannabis-containing products. As of February of 2020, cases of EVALI had caused 68 deaths in 29 states and the District of Columbia. Those numbers now are far more significant, and virtually all of them are in young adults. Teenagers are twice as likely to have “wheezing or whistling” in their lungs after vaping marijuana as compared to smoking cigarettes.

As followers of Jesus, 1 Corinthians 3:16 tells us that our bodies are the Temple of the Holy Spirit. Vaping weed is at least as bad as smoking cigarettes, and both are destructive acts that damage the body and can lead to death. As our society turns away from God and rejects the notion that our bodies are designed creations of God, young people are less concerned about taking care of them.

The consequences of rejecting God are enormous, and one consequence is the threat to our health. The COVID-19 pandemic should have made us all aware of the importance of caring for our lungs. These studies on the destructive nature of vaping have centered on young people, so the results are not due to old age.

First Corinthians 3:16 tells us of the sacred nature of our bodies. Verse 17 says, “If any man defiles the temple of God, him shall God destroy; for the temple of God is holy, which temple you are.” This is not some violence done to humans by God, but the natural consequence of abusing God’s creation. We cannot blame God when we fail to care for what He has given us.

Seaweed Farming in Underwater Forests

We live in a time of change. We need radically new ideas to handle global warming, food shortages, animal extinction, carbon footprints, and land utilization problems. God has provided more than just land-based resources to meet our food and air quality challenges. Oceans cover more than 70% of Earth’s surface, which seems to be the logical place to address some of these challenges through seaweed farming in underwater forests.

Here are a few advantages offered by seaweed:

1) Seaweed absorbs carbon dioxide. Left alone, it sequesters the carbon at the bottom of the ocean, where it can remain for centuries.

2) Humans can eat some seaweed, such as dulse (Palmaria palmata). It is a nutrient-rich red macroalga that can be used in cooking. Icelanders use it as a snack food.

3) Seaweed can be used as a feed alternative for livestock freeing massive amounts of arable land.

4) Seaweed eliminates the need for watering and applying fertilizer or pesticides while reducing land deforestation.

5) Raising seaweed advances shellfish populations, a significant food source for many people throughout the world.

6) Seaweed reduces ocean acidification protecting ocean life.

7) Seaweed can be grown in areas where land farming is almost impossible. At present, the largest seaweed farm is in the Faroe Islands 62 degrees north latitude, only four degrees south of the Arctic Circle.

Seaweed farming in underwater forests is already practiced by 50 countries around the world today. Our point is that those who blame God for food shortages and environmental issues should realize that God has given us solutions, but He expects us to use them. Instead of using the oceans to dispose of wastes, we desperately need to stop the pollution and start building ocean farms to grow food.

Why Do We Need Wetlands?

A giant wetland called the Pantanal is located mostly in Brazil and partly in Bolivia and Paraguay. It’s the world’s largest tropical wetland covering as much as 75,000 square miles (195,000 sq km). You might think that such a vast area is a lot of wasted space that should be drained and used for other purposes. Why do we need wetlands anyway?

The Pantanal is located in a depression in the Earth’s crust surrounded by highlands. Several rivers flow into the Pantanal, bringing sediment and making it an inland river delta. In the rainy season, up to eighty-percent of the floodplain is covered with water. In the dry season, the floodplain becomes dry. Forests of trees grow in the higher areas of the Pantanal. In the lower seasonally inundated areas, grasslands are growing.

The area’s topography creates various biome regions supporting plants that are native to rainforests, savannahs, and semi-arid lands. There are 3,500 plant species in the Pantanal, 1000 bird species, 480 reptile species, 400 fish species, and 300 mammal species. In other words, the Pantanal supports an incredible variety of aquatic plants and a very diverse menagerie of animals.

Some of the animals living in the Pantanal are rare or endangered. We need wetlands like the Pantanal to support these various plants and animals, plus thousands of invertebrate species. More than that, wetlands are natural water treatment systems that remove pollutants and chemicals, purifying and replenishing the groundwater. Wetlands also provide a buffer against flooding in other areas.

Why do we need wetlands? They are an essential part of the hydraulic system God created for planet Earth described thousands of years ago in Job 36:27, 28, “He draws up the drops of water, which distill as rain to the streams; the clouds pour down their moisture, and abundant showers fall on mankind.” That ancient book describes the water cycle with scientific accuracy.

We need wetlands for what they do for our water supply and the support they provide for plants and animals essential to the balance of nature. Human activity threatens the Pantanal, as well as many other wetlands. We must become better stewards of the blessings God has placed in our care.

Value of Insects in the Ecosystem

We get many interesting responses to our daily articles on this website. Recently, several people responded to our emphasis on the value of insects. Bugs can indeed bother us. Some bite or sting, while others eat our vegetation encroaching on our food supply. Despite those things, we have pointed out that entomologists tell us that insects are beneficial.

Akito Kawahara, a curator at the Florida Museum of Natural History, said that most people are unaware of the value of insects. Kawahara points out that insects annually contribute 70 billion dollars to the U.S. economy by their roles in pollination and waste disposal processing. Everyone knows that insects are involved in pollinating flowering plants, but they may not realize that insects are the linchpins, holding together almost all land-based ecosystems. Also, insects provide food sources for birds, bats, freshwater fish, and numerous land animals.

Not realizing the value of insects, humans have done much to eradicate them. We have reduced their habitat, used massive amounts of pesticides, and made them victims of pollution. Sometimes, we have brought in invasive species of animals and plants that harm the ecosystems. We have also done things that accelerate climate change. The National Academy of Sciences suggests initiating a campaign to encourage people to avoid using bug zappers, practice insect conservation, do less mowing, and use insect-friendly soaps and sealants.

God set up a working system that has produced a high standard of living for thousands of years. We are threatening to unbalance the system by our capacity for high tech devices and materials. Sometimes insect populations get out of control and damage human resources, such as the locust invasions of recent years. It is often human interference with the natural controlling agents that have caused the insect infestations. People need to be aware of the value of insects to life on this planet.

Cricket Megaphones

Have you ever thought about how a tiny cricket can make so much noise? Researchers have found that male tree crickets use leaves to make baffles that double the volume of their calls. You could call them cricket megaphones.

Cricket wings are resonance structures reverberating with the vibration caused by rubbing the wings together. This reverberation is like the body of a violin, but the sound is weak because the insect is so small. To make a baffle, the male cricket cuts a hole in a leaf and then crawls halfway through the hole, so its wings cause the leaf to vibrate like a loudspeaker. The advantage is that female crickets are attracted to the males with the loudest call.

The discussion among biologists is about whether this qualifies as tool use. Rittik Deb, an ecologist at the National Centre for Biological Sciences in Bangalore, India, says crickets show that sophisticated behaviors aren’t just for big complex brains. Deb says his work “really turns that idea on its head.”

Not everything about this behavior is beneficial to the cricket because increasing the volume of their calls makes them sitting ducks for predators like geckos and spiders. It would seem that this controls the cricket population, but it provides a food source for other living things. For that reason, it appears that evolutionary processes would eventually put a stop to cricket megaphones.

A more likely scenario is that the behavior is programmed into the crickets’ DNA to keep a balance in nature. In places where geckos and/or spiders are in abundance, the cricket population remains small. In Australia, we saw large numbers of geckos and large spiders in the homes of people with whom we stayed. We did not see insect problems in those same homes. In America, we have much to learn about the natural controls that God has built into our world. As more evidence unfolds, we see that human attempts to control insects with chemicals are unnecessary.

Biological Barriers to Evolution

For all living things to evolve from a single common ancestor, an incredible number of beneficial changes must occur. The problem is that biological barriers to evolution get in the way.

Although Darwinism looks for genetic mutations to fashion new and beneficial genetic changes, the vast majority of mutations are harmful. Since fruit flies have a short reproductive cycle, scientists have worked with enormous numbers of fruit fly generations, trying to demonstrate evolution. They have produced mutated fruit flies with four wings rather than two. However, the extra wings are a useless encumbrance to the fruit flies because there are no muscles to move them. Additionally, they are still fruit flies, not even houseflies or horseflies.

Darwin saw that the beaks of finches changed over time. However, those beak variations were not anything new; they had always been there. Changes in the habitat caused the birds with beneficial beak sizes and shapes to reproduce in larger numbers. When the climate or other conditions changed again, the predominant beaks changed again. The beak adaptations were not permanent changes, and the birds were still finches.

Mutations do not add new data to the DNA, and for a mutation to be passed on to the next generation, it must occur in the reproductive cells. A genetic change in body cells can’t be passed on to future generations any more than a woman who has had an appendectomy will give birth to a child with no appendix. Mutations in bacteria are well known and can cause them to become immune to the effects of antibiotics. But again, those are just hereditary fluctuations around a median point. They do not become new creatures.

Hundreds or even thousands of years of plant and animal breeding by humans has shown that intelligent breeding can produce remarkable changes and improvements. But new dog breeds are still dogs, and new rose varieties are still roses. If biological barriers to evolution limit intelligent humans to making improved changes within certain limited boundaries, could purely random chance mutations create the wide variety of life-forms in the world today? Billions of years are not enough time to do the impossible.
