Algae Solutions to Human Problems

Algae Solutions to Human ProblemsWhen you hear the word algae, negative thoughts may come to your mind. You may have problems with algae growths in your pond or birdbath. You have heard about toxic algal blooms that have hit seafood industries on the Pacific Coast. Many of us have viewed the red tide in Florida first hand. There are lawsuits in progress against companies that allowed chemical runoffs to trigger the destructive growth of algae in lakes and the ocean causing economic hardship for fishing trades and seafood producers. Unlike human-caused algae problems, there is a promise of algae solutions to human problems.

Consider the following facts:

Algae is probably our best tool for reducing greenhouse gases. Algae take carbon dioxide from the air and produce oxygen. More than half of the oxygen in Earth’s atmosphere comes from converting carbon dioxide to oxygen and algae is the primary agent for doing that. There is good evidence that excessive algae growth in the past caused global cooling.

Phytoplankton algae grow world-wide and make up the base of aquatic food-chains, eventually leading to most of the seafood we eat.

Giant kelp, which are algae, provide food and protected ecosystems for ocean creatures.

Cyanobacteria, also known as blue-green algae, such as spirulina contain proteins, vitamins, minerals, and essential fatty acids. People in many countries have been harvesting spirulina for nutrition since the 1940s. Japanese cooks use algae in soups and sushi wrappers. The additives agar and carrageenan from algae are used in ice cream and jellies.

Symbiotic relationships exist between algae and coral, helping to prevent storm damage to coral reefs that house sea life and protect shoreline structures. Algae solutions to human problems are many.

Research continues into how we can use algae to produce fuel. New foods made of algae are being developed. Most recently sea grapes, which are algae, have been used as green caviar because their texture and appearance looks like caviar and they are very nutritious.

God has provided for us in so many ways that it has taken our entire human history to discover them. For many years people did not eat tomatoes because they were considered to be poisonous. That seems silly to us today when whole industries are built around the tomato. In the future, perhaps we can say the same of algae. These rootless, leafless plants have incredible potential to provide algae solutions to human problems both here on Earth and as we travel into outer space.

Seeds Are Alive

Seeds Are AliveWhen you walk into the forest and look up at the trees, it’s easy to realize that all of those structures towering over your head are alive. What you may not think about is that their seeds under your feet are alive also.

Many trees produce seeds to grow new trees. There are maple seeds with their familiar “helicopter” method of blowing in the wind. There are cottonwood seeds that look like “summer snow.” Those seeds and others are carried far away by the wind.

Oak trees produce seeds we call acorns. They’re too heavy for the wind to scatter them, so that’s the job of squirrels. Squirrels gather acorns and store them to eat later. When later comes, the squirrels have often forgotten where they stored their treasure. Instead of being eaten, the acorns grow into new trees to produce more acorns. Both the trees and the squirrels benefit from that arrangement.

The seed of a coconut tree is the coconut. The wind can’t blow coconuts around, and squirrels can’t carry them. They often grow near water, such as a stream or an ocean. A coconut falling into the sea can float to an island thousands of miles away, where it can take root and grow. Cherry trees produce their fruit with a seed we often call a pit. Birds eat the cherries and drop the seeds over a wide area.

The key to a seed beginning to grow is the breaking of the shell surrounding it. Many things can cause that to happen, such as moisture, temperature, fire, mechanical abrasion, or a combination of methods. Some seeds have to travel through the digestive system of birds or animals for them to begin to grow into a new plant.

Most seeds wait a year before they start to grow. Cherry seeds can wait for hundreds of years. Scientists discovered a lotus seed (Nelumbo nucifer) in a bog in China. They cracked the shell and started it growing. When they carbon-dated the shell, they found that the seed had been waiting for 2,000 years to sprout into a lotus plant.

Seeds are alive, waiting in dormancy to grow into what God created them to be. The amazing quality of life shows design by intelligence, not chance.

A Flower or a Weed?

Daisy - A Flower or a Weed?
This wildflower can be found growing in fields and meadows. Its soft petals and yellow core make it universally recognizable. Many related plants are called daisies, but the common daisy (Bellis perennis) is native to Europe and is sometimes called the English daisy due to its native location. However, daisies have become so prevalent around the world that some say they make up almost 10% of all flowering plants on Earth. This leads to the question of whether it’s a flower or a weed.

The name “daisy” comes from “day’s eye” because the head closes at night and opens with the sunrise. You may look at the common daisy and believe that the head is a solo flower. In reality, it’s a composite flower made up of a cluster of flowers called an inflorescence. Each inflorescence grows on a single, leafless stem with rounded leaves growing from the base. Common daisies resemble another wildflower known as chamomile. However, chamomile has multiple flower heads growing on the same stalk.

Common daisies are robust and can thrive in many different types of soil, in full sun or partial shade, as long as minimum temperatures remain above -30 degrees F (-34 C). They grow on every continent except Antarctica. Daisies can grow in practically any valley, meadow, or field. If the conditions are right, daisies will populate themselves in enormous numbers engulfing the ground like weeds. A meadow full of daisies is a beautiful natural scene. However, in some areas, they are considered to be invasive weeds. In fact, they are so hardy they may crowd out noxious weeds. So is it a flower or a weed?

Daisies are beautiful to look at, but they can also be beneficial in other ways. Daisies can help improve the biodiversity of the household garden by attracting pollinating insects as well as birds that feed on the insects. Young daisy leaves can be added to salads, and they supply vitamin C. The buds and petals are also edible in soups or salads. Some people have also used them for treating gastrointestinal disorders. Children use them to make daisy chains, and young women count the petals to the refrain “he loves me; he loves me not.”

So the question of whether it’s a flower or a weed depends on your perspective. We prefer to think of them as flowers. Whether wild or cultivated, we find the number and variety of flowers in the world amazing. Apparently, God loves beauty, and He has given humans the ability to enjoy it also. After all, the Creator made us in His image.

Zoopharmacognosy Animal Doctors

Zoopharmacognosy Animal Doctors Zoopharmacognosy is a word you don’t see every day. It’s actually a combination of three Greek words which mean “animal” (zoo), “drug” (pharma), and “knowing” (gnosy). It refers to animals using plants, soils, insects, or drugs to solve specific medical problems. It is animals (not humans) medicating themselves. Mammals, birds, and even insects use zoopharmacognosy to cure medical problems, and sometimes to prevent them. Here are a few examples.

It is fairly common to see a sick dog or cat eating grass to induce vomiting.

Sick chimpanzees swallow bitter leaves of Aspilia, a plant that contains an anti-parasitic chemical. The leaves are covered with bristles and bitter tasting so the chimps roll up the leaves and swallow them whole like we might take a pill.

Others chimps and bonobos with diarrhea will split open the stem of an Aframomum plant and suck the bitter juice. The juice contains chemicals which kill parasites which cause diarrhea.

Spider monkeys in Brazil have been seen eating seed pods from a tree known as monkey ear or elephant ear (Enterolobium cyclocarpum) during mating season. The fruit contains progesterone which promotes female fertility.

Brown bears make a paste from the chewed roots of osha (Ligusticum porteri) mixed with saliva and rub it into their fur to repel insects and soothe the bites. The plant contains coumarins which repel fleas and ticks.

To get rid of lice, many songbirds with put ants on their feathers or even roll in an anthill. The ants secrete formic acid, which kills feather lice.

Ants infected with Beauveria bassiana, a soil fungus, will eat harmful substances that are antifungal.

Many kinds of animals will eat dirt to absorb toxins, to combat parasites, or as an antacid. Sometimes they eat dirt to supplement minerals that are missing in their diet.

Pregnant elephants will chew the leaves of a specific tree in the Boraginaceae family to induce labor. Kenyan women make tea from those leaves to help with childbirth. In many cases, people have learned medicines and tonics from animals.

There are many more examples of zoopharmacognosy in which animals act as their own doctors. How did animals get this knowledge? It seems to be instinctive, not learned. Perhaps this instinct was put within the genetic code of these animals by their Creator.

California Poppies Thrive

California Poppies ThriveThe past twelve months have been a time that most native Californians will never forget. After several years of drought, the entire state was affected by massive forest fires. When the fires were finally out, it seemed that everything would get back to normal, but then the rains started. Between the heavy snow and the unusually heavy rains, massive flooding became an issue. Without vegetation to stop the runoff, gloom and doom predictors were having a field day. The future looked bad, especially for southern California, but then came the California poppies.

I recently got a letter from a friend of mine who lives in southern California. The letter included pictures of what a few months ago was ugly, dark-colored, barren rock. The new images were ablaze with color. The California poppies withstood the fire because their seeds are not combustible and germinate faster in the conditions the fires produced. The seeds are also shaped in such a way that they don’t wash out even in heavy rain. With no competition, no predation to destroy the young plants, the poppies grew and bloomed like crazy.

Norma Privitt writing in the July/August/September 2019 issue of Power for Today described it this way:

“What a year this has been for California poppies! Abundant rain has unleashed God’s glorious array of orange flowers over all the barren hills. Even the limitations of TV do not restrict the obvious explosion of color. We traveled to view the poppies in previous years when their glory was only a smidgen of this year’s, but so many have made this year’s pilgrimage their cars line both sides of the roads, and finally, shuttle buses have had to be arranged. It almost seems symbolic that the plant that will anchor the soil and allow the land to begin to recover is a plant that blooms with brilliant orange drawing attention to God’s provision, even when human greed and abuse cause pain.”

Through California poppies, God has provided a way to bring beauty and hope even when things look dark and bleak.

Saguaro Desert Old-Timers

Saguaro Desert Old-TimersThe saguaro (pronounced suh-wah-roh) cactus is found only in the Sonoran Desert areas of southern Arizona, northern Mexico, and a small area of southeast California. We call them saguaro desert old-timers for a good reason. Saguaros grow very slowly as a single stem for perhaps 75 years before developing arms. Plants with five arms may be 200 years old.

Saguaro flowers bloom at night from April to June. They close by noon the next day, never to open again. Saguaro flowers can only be fertilized by cross-pollination so there must be a creature to carry pollen from one plant to another. Because the flowers bloom at night, bats are the pollinators. They drink the nectar and transfer pollen from plant to plant.

A successfully pollinated flower will produce a green, oval-shaped fruit with bright red pulp. Many desert creatures eat the fruit and aid the saguaros by spreading their seeds. Only a small percentage of the seeds will ever germinate, but that’s okay because each flower produces as many as 4000 seeds.

Not only do the saguaros have a symbiotic relationship with the bats which consume their nectar and the many creatures who consume its fruit, but it also provides shelter for many desert animals. Saguaros become apartment houses for birds, lizards, desert rodents, and reptiles, as well as a whole entourage of insects.

Saguaros are remarkably well-designed for life in a dry climate. The outside of the plant has pleats like an accordion. The pleats allow expansion for storing large quantities of water when the rains come. As with other cacti, the saguaro has needles rather than leaves to reduce the loss of moisture by transpiration.

Saguaro desert old-timers are designed in a marvelous way to live in the harsh conditions of the desert while providing food and shelter for various desert creatures. They are another indication of a Master Designer of life.

Beautiful Tulips in History and Culture

Beautiful Tulips in History and CultureTheir vibrantly colored blossoms are symbolic of spring. Tulips are part of the lily family (Liliaceae) and exist in many different species. They flower in the spring and die back in summer when the life is stored in an underground bulb until the next spring. Beautiful tulips are an excellent example of the beauty designed into this planet.

Tulips are known for their bold colors and attractive shape. Most varieties are almost perfectly symmetrical. The blooms have three petals and three sepals, but the tulip appears to have six petals because the sepals are large and generally the same color as the petals. You can find tulips in almost any color from white to black, but the bright and sunny colors are the most popular.

Without a doubt, beautiful tulips have a rich and interesting history. They originally grew wild in temperate areas from southern Europe to central Asia. They were first cultivated in Asia around the tenth century. Diplomats who visited the Ottoman Empire in the sixteenth century brought them back to Europe where they became hugely popular.

The tulip obsession began with Flemish botanist Carolus Clusius in 1594. He was the first person to identify “broken tulips,” which is a virus infection that causes impressive streaks in the petals. He would go on to create many different color variations of the flower. His amazing tulips led to a period from 1634 to 1637 called “tulip mania” when enthusiasm for the flower created an economic frenzy. Tulips quickly became the most expensive flowers in the world. At the peak of tulip mania, some bulbs were selling for ten times more than the annual income of a skilled worker. People even used tulip bulbs as currency. Artists of the Dutch Golden Age, including Rembrandt, depicted tulips in their paintings.

Today, the tulip is the national flower of Turkey and Afghanistan, but the most prolific producer of tulips is the Netherlands. There are annual tulip festivals around the world including the Netherlands, England, Switzerland, Canada, and even Australia, where the spring bloom occurs in September and October. Several locations in the United States have tulip festivals, including Holland, Michigan, which is near where we live.

It’s interesting how tulips could have such an impact on economics, culture, and history. God gave us beautiful tulips, and human intelligence has modified them to develop a variety of colors and patterns. If human intelligence could do that, think how much more intelligence was required to create the living plant with the genetic code that made it all possible.

Petoskey Stone Dilemma

Petoskey Stone TilesEvery part of the United States has rocks, plants, and animals that are unique to that area. Certain plants grow in abundance in various locations. In Arizona the saguaro cactus is abundant. California is home for giant redwood trees. Indiana has tulip trees. Many states have adopted an official flower, tree, bird, fossil, or rock. In Michigan, since 1965 our state rock has been the Petoskey stone.

The name comes from the city of Petoskey which got its name from an Ottawa Indian legend. Thanks to the glaciers that swept down from the north scooping up rocks and depositing them, Petoskey stones are found all over the state. When I took my earth science students to the local gravel pit, we would discover Petoskey stones mixed in with the gravel. A local jeweler would show the kids how beautiful jewelry could be made from those stones.

The Petoskey stone is a petrified tropical coral with the scientific name Hexagonaria, meaning six-sided chamber. The picture shows some tiles made from Petoskey stones, and you can see that each polyp has six sides. Mixed in with them are clams, crinoids, trilobites, fish, and cephalopods. Studies of the Petoskey stone show the coral lived on plankton which are microscopic life forms that live in warm oceans. Petoskey, Michigan is NOT a tropical paradise and the Devonian period when these life forms lived lasted a long time, so the Devonian reefs are very thick. The whole state of Michigan is a bowl with these fossils found all around the state. In the middle of the bowl are coal, oil, peat, sulfur and natural gas deposits. The dilemma is how these rock formations got to be the way they are and where they are.

Some religious folks might suggest that this is a deposit produced by the flood of Noah. The problem with that explanation is that this is not a flood deposit and is not a product of violence. Genesis 7:11 tells us that “all the fountains of the great deep were broken up and the windows of heaven were opened.” I would take my students on a field trip to the Shedd Aquarium in Chicago to see a reef display. The rocks being formed and making up the reef are identical to the ones we see in the Devonian deposit. The fossils don’t show a violent end, but instead, they show a slow, gentle formation process. Calcite, silica and other minerals have replaced the original material in the cells of the Petoskey stone animals, giving a dazzling array of colors.

When God created “the heaven and the earth” (Genesis 1:1), the Bible simply states that He did it – not how He did it. At the end of verse 1, there were Petoskey stones in Devonian reefs, and oil, gas, coal, and the other resources were being formed. A change was coming that would make the conditions of the Earth more hospitable for human life, and God knew what we would need for an advanced civilization. Having a warm ocean covering the entire state of Michigan was not an environment humans could thrive in, but it was a tool God used to prepare the resources for human life.

There is no dilemma if we take the Bible literally and accept only what it says. Locking the creation account into a denominational theological tradition does violence to the Genesis account and causes young people to question the truth of the Bible. On the other hand, as they admire the beauty of the Petoskey stone jewelry they have made, people can realize that God has done some special and beautiful things to prepare a home for us in this life.

Does Intelligent Design Destroy Science?

Does Intelligent Design Destroy Science?Skeptics claim that Intelligent Design destroys science. This claim shows how badly the skeptics misunderstand intelligent design.

The dictionary defines science as knowledge. When we do scientific experiments and make observations, we are trying to gain knowledge. We apply that knowledge to those situations where we can gain more knowledge. We never just say “God did it” and stop investigating. We continue experimenting because we want to understand how and why God did it. Believing that there is design in all aspects of the creation never stops us from looking for a deeper understanding. Naturalism is frequently just the opposite. A classic example of this is Junk DNA.

As naturalists examined the DNA in various animals, they found that there was DNA that didn’t seem to be necessary. They called it “Junk DNA” assuming that it was a byproduct left over from the evolutionary process. For many researchers, that was the end of the story. No further experiments were designed to find a purpose for junk DNA. In this case, a naturalistic view and assumption stopped the scientific investigation, or at least slowed it down.

A biology professor chastised me for referring to junk DNA as a dead-end street. His exact words were “God doesn’t make any junk.” The assumption that junk DNA wasn’t junk led to further investigation. That research now tells us the so-called “junk” has a purpose and plays a vital role in life processes. Believing that everything we see was created with a purpose and a design, and wanting to understand that design is a great catalyst for scientific investigation.

Historically, most of the significant discoveries of science over the past 1000 years have been made by scientists who recognized purpose and design in the cosmos. They were striving to understand that design. In our quarterly journal (which you can read on doesgodexist.org), we have a column titled “Scientists and God.” We present statements by leading scientists about their faith and their recognition of purpose and design in the creation. Does Intelligent Design destroy science? No, it supports science.

We quoted Albert Einstein in our first quarter journal for 2019 when he said:

“We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written the books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangement of the books, but doesn’t know what it is. That, it seems to me, is the attitude of even the most intelligent human beings toward God. We see the universe marvelously arranged and obeying certain laws but only dimly understand these laws.”

Whether we study biology or quantum mechanics, Intelligent Design enhances science because the universe was intelligently designed.

God’s Horticulture System

God's Horticulture SystemOne of the most interesting designs in the natural world is the way plants are seeded. For plants to grow, there must be soil, moisture, and the planting of the seeds. Many places have moisture and soil that could support plant life, but how do you get the seeds to that area? The solution is God’s horticulture system.

In our area of the world, we have seen human influence cause an area to be bare of significant trees or vines. The building of highways or the destruction of fires and floods can leave an area completely void of any kind of plant growth. Around the interstate highway system in our area, we see the growth of red cedars. These desirable trees are slow growing and can become valuable timber. The state doesn’t plant trees, and yet many red cedars are growing along our highways.

The animals planting these evergreens are birds. The cedars provide valuable habitats for the birds, and the birds plant the trees. Cedars produce blue berries that the birds eat. If you put one in your mouth, you would cringe at their bitter taste and obnoxious consistency. Birds eat them with zest and in large quantities. Birds get nutrition from the berries, and their digestive systems are specifically designed to process the seeds for growth. The birds drop the seeds along with natural fertilizer in barren places. Birds and trees benefit from this symbiosis in God’s horticulture system.

Other important seeders are squirrels. They are designed to bury seeds such as acorns, but their brain limitation causes them to forget a percentage of the seeds they bury. The design of fruits and nuts provide nutrition for animal life while the animals provide a means for the plants to grow in places far from their ancestors.

When scientists look at the diet of dinosaurs by examining their petrified excrement, they find that dinos were the seeders of their day. The plant-eating dinosaurs spread the seeds of the plants they ate along with nutrients that allowed fantastic jungles to form. The meat-eating dinosaurs kept the population of plant eaters under control so they wouldn’t eat all of the plants.

When we look at all the different kinds of seeds, the nutrients they contain, and where they can grow, we see a plan and design. Humans are still learning how to copy God’s horticulture system to feed our growing population.
