Soil Moisture and Water Shortages

Living on a river that feeds Lake Michigan, we tend to ignore messages of water shortages. There is some irrigation in our area, but nothing like what we see in other regions of the world. Recent studies of global soil moisture show a very different picture.

Drought events at various global locations have caused the loss of 1.614 gigatons of water between 2000 and 2002. (One gigaton is one billion tons.) In the United States, irrigation has been highly contested as rivers in Nebraska and Colorado cannot supply the water needed to grow wheat and other grain crops. Drawing from the water table has caused it to drop over 10 feet in recent years.

Studies at the University of Texas and Seoul National University show that the problem of water shortages will cause more hunger and human suffering if we don’t do something to stop the soil moisture loss. The solution to water shortages is available.

There was no way to recover water lost to the oceans in the Old Testament days, but now there is. We can use nuclear energy and various processes to desalinate seawater. Removing the salt from seawater provides the salt humans need while producing fresh water for irrigation and replacing soil moisture.

God has provided humans with the water we need. In ancient times, humans lived by bodies of fresh water. With the expanding human population, not everyone could live on the shores of lakes or along rivers, so water had to be moved from places of plenty to places of drought. The Romans did this with aqueducts stretching for miles. In the western United States, we can allow rainfall and mountain ice melt to replace soil moisture while supplementing the need for water in cities by the ocean, like Los Angeles, using desalination.

The teachings of Jesus were ones of peace and concern for others. Water shortages have fueled greed and rivalry in areas of our planet. We need to use the nuclear energy God has given us to desalinate water rather than as a tool of war.

Designing an Elephant Trunk

We all know that elephants have useful trunks. As we learn more about what an elephant’s trunk can do, the more impressive it becomes. Designing an elephant trunk is not a project of chance.

The trunk is not just a snorkel. It is a highly complex device with 40,000 muscles and 150,000 separate muscle fascicles, bundles of muscle fibers. There is no bone or fat in the trunk. The Week magazine published a list of some of the characteristics of a captive elephant at Zoo Atlanta. They include:

1) Inhale water at speeds over 490 feet per second. (That’s 30 times faster than a human sneeze).

2) Issue a 110-decibel trumpet-like blast. (120 dB is considered the human limit without pain.)

3) Suck up food. (A skill thought to belong only to some fish.)

4) Rip up trees and lift 770 pounds. (350 kg)

5) Reach up to 23 feet. (7 m)

6) Hold 2.2 gallons in the trunk. (8.3 l)

7) Detect smells four times better than a bloodhound.

8) Lift a tortilla chip without breaking it.

The more complex a device is, the less likely it is to be the result of an accident or a series of accidents. The difference between the human nose and the elephant trunk is so striking that we should abandon attempts to relate the two. Lead researcher Andrew Schulz from Georgia Tech says that their research “pushes all of the extremes of what we understood animals to be able to do.”

The challenges of designing an elephant trunk strongly suggest that intelligence was involved. This is one more example of the credibility of the statement in Romans 1:20, “We can know there is a God through the things He has made.”

Donkeys Digging Wells in the Desert

We don’t ordinarily think of donkeys as diggers, especially not as vital to the desert environment. A researcher from Aarhus University in Denmark has made a discovery that shows a special provision God made to use donkeys to provide water for other life forms. Erick Lundgren has documented donkeys digging wells in the desert. In 2014 Lundgren studied feral horses and donkeys and noticed them digging holes deep enough to reach groundwater.

From 2014 to 2018, Lundgren mapped groundwater in Arizona’s Sonoran Desert and found that holes dug by donkeys provided 74% of available water for all forms of life in the area. The donkeys seemed to know where to find water, and 57 vertebrate species from migratory songbirds to mountain lions and even a bear came to the donkey wells to drink.

It is fascinating that this is not a local anomaly. Researchers have documented donkeys digging wells in Central Asia, so this action is built into the donkey’s genome. Attempting to make a case for accidental donkey well-digging fails when isolated populations have the same instinctive drive. They use it not only to survive themselves but to benefit an entire ecosystem.

Research into donkeys digging wells shows that the donkeys know where to dig because the digging is not random. The wells dug by donkeys decreased the distance between water sources to an average of 843 meters, making essential water available to more animals with less tension. We suggest this is a beautiful example of God’s design allowing animals to live in environments that would seem unlikely to support life.
