How Do Sea Animals Drink Water?

Wandering Albatross - How Do Sea Animals Drink Water?
Wandering Albatross

Yesterday we discussed how fish drink water. In the ocean, the problem isn’t water but salt. Ocean fish are designed with specialized gills that support the kidneys in getting rid of salt accumulations that would otherwise pickle the fish. Obviously, not all animals that live in the ocean have gills. How do sea animals drink water?

Albatrosses and petrels are birds that can spend a year or more in the open ocean, but they need to drink water. Whales and seals also do not have land-based water supplies, and yet, like all mammals, they need water to survive. So how do sea animals drink water when ocean water is salty? God’s design of living creatures always includes unusual equipment to enable them to deal with their environment.

In the case of sea birds, they have a set of salt glands in their heads that connect to the bird’s nostrils. The birds drink seawater, but the glands are so efficient that within three hours, all of the salt is removed through the nostrils.

Whales and other aquatic mammals produce urine that has extremely concentrated salt content. By allowing high salt concentrations in the urine to diffuse into the ocean, the salt never reaches toxic levels inside the animal. An interesting sidelight to this is that the milk of these sea mammals is very low in water content. In that way, they conserve water. Milk from seals has only half the water content of lean hamburger.

Everywhere we look in the natural world, we see that a wonder-working hand has gone before. These marvelous designs are not the product of mindless chance. They show an Intelligence who created with purpose and wisdom. When we realize that ocean water has high salt content, we question, “how do sea animals drink water?” God already took care of that.

In Job 38-40, God challenged Job to advance his understanding of God’s power and wisdom by considering the natural things of creation. When Job questioned God’s wisdom and purpose in his personal struggles, he did not recognize the wisdom shown in creation’s design. We too need to look at what God has done and “know there is a God through the things He has made” (Romans 1:18-20).

Ants Use Vibratome to Cut Leaves

Ants Use Vibratome to Cut Leaves

Yesterday we wrote about leaf-cutting ants that engage in farming activity, which we used to think only humans did. The 1994 Disney movie Lion King started many people thinking about what these ants do. There is another tool leafcutter ants have that is impressive. These ants use vibratome to cut leaves.

Vibratome is sound emissions that alter the structure of matter close to the sound. Biologists use sound waves to prepare specimens to be sliced for microscopic examination. The sound waves cause soft material to become more rigid and, therefore, easier to cut. Ants had used vibratomes long before scientists discovered it.

As we said yesterday, leafcutter ants in the Atta genus slice off sections of leaves and carry them to their nests to feed the fungi they harvest. Researchers have found that as the ants cut, they chirp at a frequency of 1000 hertz. That sound frequency rigidizes soft leaf tissue, making it easier to cut. Vibratome is a technically sophisticated technique and one you would expect skilled technicians to use. Materials science is a relatively new field, and yet ants have it built into their DNA to chirp at a specific frequency as they cut leaves to feed the fungi they eat.

How is it that ants use vibratome to cut leaves? How did they know that it would stiffen the leaves and allow them to make a smoother cut? Scientists further discovered that the vibratome effect does not speed up the leaf-cutting. However, it enables a smoother cutting of the tender leaves, which the scientific report said gives “the most desirable harvest for the ants.”

God created the leaves as well as the ants that use the leaves to feed the fungi they eat. He gave the ants wisdom to use vibratome to cut leaves. The writer of Proverbs reflects God’s wisdom and intelligence in 6:6-8, “Go to the ant … consider her ways, and be wise.”

Ant Farmers at Work

Ant Farmers at Work
Leafcutter Ants at Work Taking Leaf Cuttings to the Colony

We commonly think of animals as opportunists. They find their food and eat it or store it for future eating. One of the characteristics of humans that distinguishes us from the rest of the animal kingdom is that we prepare an environment that produces our food. Farmers plant seeds and tend the crops by fertilizing, protecting from threats, and watering when necessary. They also make arrangements for future crops. Entomologists are finding more and more cases where insects do these same things. For example, ant farmers work together to produce their food.

In Fiji, a plant called Squamellaria grows in a cluster with jelly-bean shaped bubbles inside. The opening into the clusters is just the right size for the Philidris nagasau ant to get into the bubbles. As the bubbles send out shoots, the ants defecate inside the cluster, fertilizing the plant. When the plant blooms, the ants eat the nectar it produces. The ants then plant the seeds where new clusters can grow.

Another family of ant farmers is the Atta genus. In their farms, they grow a fungus species that they nourish with leaf cuttings. After cutting off leaf sections, worker ants carry them back to the colony. As the workers transport the leaf cuttings, others ride on the leaves to protect against a parasitic fly species. You might call that pesticide.

At the colony, other ants pulverize and defecate on the leaves to make them ready to nourish the fungi. The ants can’t eat the leaves, but the fungi are their food, and only one fungus species is edible. If another fungus species develops, the ants produce a toxin, which destroys only the invading fungus. This is herbicide use at its best. The Atta ants inspect the fungus several times a day, tending it carefully. The system is so efficient that one Atta nest can grow enough fungus food to feed seven-million resident ants. In the process, the ant colony produces fertile soil that promotes plant growth.

If you saw the 1994 Disney animated Lion King movie, you saw Atta ant farmers at work. Remember that fungi are not photosynthetic. No sunlight is needed for Atta ants to grow their food. They simply carry in the nutrients for the fungi to grow, and then they eat the fungi. We do the same thing with much of our meat, providing plant material for chickens or pigs to eat, and then eating the animals that we fed. In the case of the ants, they eat only one food, which simplifies farming enormously.

We know it takes incredible planning and design to manage a farm. No chance process produces most of the foods we eat. It requires meticulous planning and careful application of fertilizers, pesticides, and herbicides. As scientists study insect farming, they see a design that is carefully and intricately produced.

Data on the ant farmers came from Science News, April 25, 2020, pages 16-20. The subtitle of the article is, “Could our agricultural role models have six legs?” This reminds us of the challenge in Proverbs 6:6-8: Go to the ant … consider her ways, and be wise. She has no guide, overseer or ruler but provides her food in the summer and gathers her food in harvest.” The title of the article is “The First Farmers.” We might amend that to be “God’s First Farmers.”

Christian Concept of Hope

Christian Concept of Hope

We read in 1 Corinthians 13:13 “And now abides faith, hope, love, these three. But the greatest of these is love.” How can hope be listed as a foundation of being a Christian? The answer is that the Christian concept of hope does not mean “wish.”

The lexicon tells me that the word translated hope literally means to expect, to look for, to await. It is not to wish for something to happen. In Romans 4:16-22, Paul speaks of Abraham being the father of many nations, and he says Abraham “believed in hope”? Does that mean Abraham hoped that God did not lie to him about his future? That is absurd. Verse 19 tells us that Abraham believed and was not weak in faith. Abraham’s hope was looking for what was about to happen.

The Christian concept of hope does not depend on what we possess, what we can do for ourselves, nor what any other human may do for us. We don’t hope (wish) that we will go to heaven. We look forward to it. Read 2 Timothy 4:6-8 and see if you think Paul expresses the WISH that heaven awaits him. He looked forward to heaven.

Over and over, we see this Christian concept of hope in the Bible. In 2 Corinthians 1:10, Paul wrote, “On Him we have set our hope that He will continue to deliver us.” He did not say we wish He could or would. Colossians 1:27 speaks of the “hope of glory.” Not that we wish it was, but that we are waiting for it. In 1 Thessalonians 5:8, Paul refers to Christians and repeats the message of our key passage in 1 Corinthians 13:13. He wrote, “Let us be sober, putting on the breastplate of faith and love; and for the helmet the HOPE of salvation.” Notice that this is a covering for the head, the most sensitive part of our bodies. Notice it is not the “wish of salvation.” It is “the hope of salvation.” It is the expectancy, the things we are waiting for.

In Hebrews 6:17-20, we see this stated again. Read the passage. Notice that there are two unchangeable things. One is that God cannot lie. The other is that our HOPE is an anchor for us. That is our promise of salvation. In Romans 15:13, we see God referred to as the “God of HOPE.” The God of promise. The God we can look forward to. Not the God of “maybe” or “possibly” or “could be.” Things like the current pandemic can be approached fearlessly by Christians because we have the assurance that something better is coming – guaranteed!!

Medical Miracle Cure Claims

Medical Miracle Cure Claims

It was bound to happen. With the legalization of medical marijuana and substances made from marijuana, people are making claims about what cannabis can cure. It goes beyond simple aches and pains to include every ailment and life-threatening disease. We must beware of medical miracle cure claims.

Religious figures have promoted miracle oils from God that they claim to have special powers to cure things that the medical establishment deems hopeless. In our January 12 post, we talked about witches and the problems with the translation of biblical words. What your translation of the Bible may call witches or witchcraft were actually people who claimed to have magic, miraculous cures for every ailment possible. In Acts 8:9-11, we read about a man named Simon, who had quite a business going with this type of activity, and there are examples in the Old Testament.

It is a wonderful thing if some natural substance or diet can help a person with their ailments. There is certainly no problem with people making a business out of selling these products but beware of hyper-sensationalized claims of miracle cures.

As I write this, I have a family member who is dying of cancer. Hospice is caring for him, and he has only a few more days to live. What started as prostate cancer has gone to bone cancer and a massive brain tumor. When the bone cancer was detected, the family member was taken to a marijuana clinic where he was placed on a treatment of marijuana compounds and a strict diet endorsed by some religious leaders. This treatment went on for many weeks.

Standard medical treatment did not have a cure for the bone cancer, but it could be controlled, and the life expectancy would be for many years. My family member was told that marijuana treatment could eradicate the bone cancer. There were even a few “testimonies” given by people who claimed they had been cured. Eventually, it became evident that the cancer was growing, not shrinking, and by the time they stopped the marijuana treatment, a baseball-sized tumor had developed in the brain. Because the marijuana treatments had replaced standard medical procedures, there was nothing that could be done.

We should examine medical miracle cure claims of any kind with skepticism. We are not talking about cosmetic issues or supplements for simple aches and pains. We are talking about major issues like cancer, mental disorders, and diabetes. God warned ancient Israel about miraculous enchantments and potions, and we must heed that warning today (Galatians 5:20).

Decline in Practicing Christians in America

Decline in Practicing Christians in America

The Barna Research Group is a research agency that has been doing statistical analysis of religion since 1984. Their studies are widely recognized as academically valid. One useful part of Barna’s work is that they repeat studies to identify trends. Research this year indicates a decline in practicing Christians in America.

Barna defines a practicing Christian as: “Someone who identifies as a Christian, agrees strongly that faith is very important in their life, and has attended church within the past month.” In the year 2000, 45% of Americans surveyed identified themselves as Christians using that criterion. In February of 2020, that percentage had dropped to 25%. This research was based on interviews with 96,171 adults.

When you think about the numbers associated with the Barna definition, it is evident that the word “practicing” is the weasel word. Many people who claim to be Christians have not made a practice of attending Church services. At the same time, they would probably be upset to be called “non-practicing Christians.” However, the truth is that Barna used the same set of questions in 2000 and 2020. There can be no doubt that there has been a sharp decline in practicing Christians in America.

It may be that the coronavirus pandemic will pull some of us away from making a god out of our material possessions. But unless we replace our zeal for things with enthusiasm for the teachings of Jesus Christ, we will continue to be poorly equipped either for this life or for eternity.

Michigan Fruit Trees and Global Warming

Michigan Fruit Trees and Global Warming

There are all kinds of evidence that we are in a period of global warming. Many of the examples don’t have so much to do with temperature as with heat. Glaciers, for instance, stay pretty much at the same temperature under the surface. But ice requires 80 calories of heat per gram to melt, without changing the temperature. You can see that when you put ice cubes in your tea. You can also see the effect of global warming on Michigan fruit trees.

We live in an area rich in fruit-growing with apples, peaches, pears, cherries, grapes, and blueberries being major cash crops. My friends who make their living with Michigan fruit trees are very upset with the current weather cycle because it has not been cold enough. Fruit trees require time and temperature to know when to blossom and when not to. They do this by a sophisticated design system. Most fruit trees need a minimum of 250 hours of temperatures between 35 and 50 degrees Fahrenheit (2 to 10 degrees Celsius), and some require up to 1000 hours. Temperatures below freezing don’t count.

The “chilling hours” are sensed by the buds on the trees, not the roots.
The wisdom in this system is obvious. Michigan winters usually have many days when the temperature goes below 10 degrees C, but there are also those rare days when the temperature gets very warm. This past winter, we had fewer than normal hours in the required temperature range. The buds have not gotten enough chilling to tell them to open. If they didn’t have the built-in time requirement, you can understand what would happen. The first time the temperature dipped below 10 degrees followed by a warm day, the buds would open and blossom only to be killed by the next cold snap.

Trees that are native in southern latitudes don’t bear fruit well when they are moved north. God has suited plants to different climates as well as other environmental factors. Orchards are found near bodies of water for several reasons. One of them is the tempering effect the water has on the air temperature. The presence of Lake Michigan provides a heat sink for our Michigan fruit trees that is as important as the moisture itself. The Psalmist seems to have had some idea of this when he compares a righteous person to a tree: “Blessed is the man who does not walk in the counsel of the wicked … He is like a tree planted by streams of water, which yields its fruit in season” (Psalms 1:1-3).

My fruit-growing friends have learned to understand and work with God’s design for their trees, but sometimes weather anomalies can frustrate their best efforts.

Christian Witness During the Pandemic

Christian Witness During the Pandemic

We are all aware of the destructive nature of the pandemic we are enduring. There is no question about how the virus is impacting families and the economy of the country. At the same time, some positive things are happening because of Christian witness during the pandemic.

There is a story circulated by SAT-7, an interdenominational Christian television center in the Middle East, which demonstrates how the coronavirus is being beneficial. A man in Iran called the television station and said that the people talking on the station were not like the ones that dominated his country. He said he couldn’t believe that they weren’t violent but had a joy and peace about them which he found attractive. He didn’t have a clue as to who Jesus is. However, he knew that what Jesus was saying was better than the violence, terror, and killing that were a part of the religion that dominates his part of the world. He wanted to know where Jesus lived so he could visit Him.

A week later, this man called again, but this time he had 25 young men crammed into a tiny apartment, and all of them wanted to hear about Jesus. Secret house churches are blossoming all over the Middle East. The coronavirus allows Christians to show compassion and bring help and necessary medications to people who are suffering. Similar stories are coming from Afghanistan.

In America, the coronavirus is showing the huge contrast between atheist beliefs and what Christianity offers. Survival of the fittest as a guide to life doesn’t work well with a pandemic. Isolation and competing for medicine and medical care are not attractive lifestyles for most people. Christians who are first responders talk about the dominance of believers in their efforts. The idea of serving others and saving lives even at personal risk to themselves is the exact opposite of atheistic belief systems.

The coronavirus is not God’s retribution for human sin, but, “All things work to the good of those who love the Lord” (Romans 8:28). Christian witness during the pandemic brings a shining light in a culture that suddenly finds itself unable to manage. In this crisis, atheism offers no hope except perhaps personally, selfishly surviving the plague in whatever way possible. True atheism has no thought of helping others or being confident about the future, even if this life comes to an end. The contrast is a great apologetic for Christianity.

Water Cycle and Life

Water Cycle and Life

Many passages in the Bible seem to be of little significance, yet they are incredibly important. Here is one of them about the water cycle.

“All streams flow into the sea, yet the sea is never full. To the place the streams come from, there they return again.” Ecclesiastes 1:7.

It is believed that Solomon wrote those words in 977 BC. What did people understand about the hydrologic cycle, or water cycle, at that time? The answer, of course, is “very little.” Meteorologist Dr. Joseph Scott Greeson says about this passage, “Without using modern words – like ‘evaporation,’ ‘condensation,’ and ‘precipitation,’ this passage describes the results of those processes in these words… My twentieth-century scientific mind recognized that the writer of that passage must have had quite an understanding of the interaction between water on earth and water in the sky.”

There is a delicate balance of processes in the hydrologic cycle that allow us to have water even far from a lake or ocean. Many years ago, I had a friend who was involved in seeding clouds with silver iodide to stimulate them to produce rain. I knew that he was involved in this project and that he had many stories about how the seeding of clouds worked. I also knew he got out of that business, and I asked him why? His response was, “We were doing okay in getting rain started, but we were doing very poorly in knowing how to stop it.”

Global warming is bringing water to places that previously were deserts. We know that temperature controls how much water is lifted into the air by evaporation. A one-inch rainfall over a square mile of land involves the lifting of 72,483.84 tons of water. (Do the math. Water is 62.4 lbs per cubic foot. An inch is 1/12th of a foot, so the volume of water in a square mile of land would be 5280 feet/mile x 5280 x 1/12th or 2,323,200 cubic feet.) How many square miles of land receive an inch of rain in a typical spring storm? This is the start of the water cycle.

As the water flows into streams and rivers, it nourishes everything in its path, ultimately returning to the sea from which it evaporated. The system that powers the hydrologic cycle is massive, and all of life depends on it. God used the water cycle to impress upon Job that he “darkens counsel with words without knowledge” (Job 38:2). After talking about the creation, God takes the hydrologic cycle as the first evidence of His knowledge, design, and power. “Who provides a channel for the torrents of rain and a path for the storm to water a land where no man lives, a desert with no one in it to satisfy a desolate wasteland and make it sprout with grass. Does the rain have a father? Who fathers the drops of dew…” (See verses 22-30).

Be thankful for the rain that brings life to us and for the water cycle that God designed so that, if properly managed, we all have enough to drink and to grow our food.

Deepwater Horizon Oil Spill Ten Years Later

Deepwater Horizon Oil Spill
BP Deepwater Horizon oil spill in 2010.

On April 20 of 2010, the Deepwater Horizon oil spill began. By the time technicians could bring it under control, it had dumped 134,000,000 gallons of crude oil into the Gulf of Mexico over 87 days. Ten years after this disaster, we still see the effects in ways that no one would have expected. The entire issue of National Wildlife for February-March 2020 was devoted to new data on the long-range damage.

There is far more involved in this disaster than the removal of the obvious symptoms of the spill. Even on a commercial level, the damage is more than most people realize. Oyster production from Apalachicola to Galveston has collapsed. Louisiana has lost well over 50 million dollars in oyster harvest revenue. Scientists studying the oyster beds tell us that 8.3 billion oysters died as a result of the spill. A single oyster can filter up to 50 gallons of water a day. When explorers came to the Gulf of Mexico between 1600 and 1800, they described the oyster beds as “the Great Barrier Reef of the Americas,” nearly 100 miles long and several miles deep. Oyster shells are used to make mortar, build roadbeds, and to supplement chicken feed. The Deepwater Horizon oil spill has changed all of that.

The massive killing of wildlife has been well-publicized with pathetic pictures still showing up on the web. Does the killing of 30,000 loggerhead turtles, 17% of the Bryde’s whales, 800,000 coastal birds, a vast number of dolphins who are still having lung problems, and 20% of all corals in the area have any significance for those of us living far from the Gulf of Mexico? Most of us eat shrimp, crabs, lobsters, and fish. Much of the fishing industry in the Gulf has gone out of business, and those still existing are hard-pressed to find enough seafood to make a living. That results in higher prices and the risk of pollution effects on what we eat.

So why are we reminding our readers of the consequences of the Deepwater Horizon oil spill? Skeptics criticize any notion of God creating the Earth by saying that if there is a God, He didn’t do a very good job. Humans are threatened with shortages of food and water. In my mail yesterday, I received 16 different requests from organizations wanting financial help in feeding and helping hungry children and starving families. (By the way, all of them were faith-based). Why are there shortages? Human greed, selfishness, ignorance, desire for power, and refusal to live as God told us to has resulted in destructive wars, mismanagement of resources, waste of incredible proportions, and foolish and irresponsible management of resources.

When God created the Earth, He provided for an abundance of food and water. God also told us how to live. Read Matthew 25:34-40 and see how Christ portrayed Christian living. The Deepwater Horizon oil spill is just one human failure, but look at what it has done to innocent humans. We are just beginning to understand the biological damage and effects. We cannot blame God for what humans have done. God has given us all we need and the means of taking care of it. Christians must lead the way in the responsible use of God’s gifts.
