Role of Elephants in Desert Survival

There are many natural situations where, to a casual observer, an animal or plant appears to be a useless consumer of resources. As conservationists try to solicit funds to protect elephants, others say those animals have no useful function. Elephants consume vegetation which can cause hardships in periods of drought. However, as scientists study the role of elephants in desert survival, the need for these animals has become increasingly understood.

Savannah elephants live in eastern and southern Africa, with the highest densities in Botswana, Tanzania, Zimbabwe, Kenya, Zambia, and South Africa. In those regions, termites build huge mounds, and they bring a large number of elements and compounds to the surface as they dig. Eventually, the mounds flatten, creating depressions that fill with water during the rainy season. At that time, elephants come and dig up the nutrients they need as they wallow in the mud. They leave the area coated with soil which they carry away, leaving a deeper depression that eventually becomes a large water hole.

In addition to enlarging the water hole, the elephants deposit massive amounts of dung. The dung contains plant seeds that grow to become the start of vegetation around the water hole. That vegetation brings insects which, in turn, bring birds. Wading birds carry in fish eggs, bringing a wide variety of life to what was a desert. The oasis this process produces is critically essential to animal and plant life and humans.

The role of elephants in desert survival in Africa makes preserving them a key to the survival of all life in the region. Elephants have unique properties critical to the success of this system. Matriarch elephants remember where previous water holes were and lead their group back to dig and enlarge those holes, eventually making it an oasis. Some plants are correlated to bloom and provide seeds at the proper time for other forms of life. If the water hole dries up, some fish, amphibians, and reptiles can burrow into the soil and survive for up to five years, waiting for the next rain.

Earth’s design automatically produces all kinds of ecosystems, including deserts. God has designed life to adapt and exist, even in extreme environments, and the role of elephants in desert survival is a great example.

Where Are the Christians?

We sometimes hear people say that America is a “Christian Nation.” That statement today is wrong in several ways. The facts show that only 9% of all people in the world who call themselves “Christians” live in North America (the U.S. and Canada). So, where are the Christians?

The home of 51% of the world’s Christians is in Africa and Latin America. Africa alone has 26%. The report shows that 23% live in Europe, 16% in Asia, and 1% in Oceania. Realize that these numbers only tell us people who claim the religious identity of “Christian.” That doesn’t mean a person attends any worship services.

When we correspond with our friends in Africa and South America, we find them talking about the stabilizing influence of Christ. They say that things are improving in their nations because of Christianity. As we look around in America, we see increasing violence and instability. Does anyone want to suggest a reason for that? Where are the Christians?

Race and Skin Color

Why do humans have different races and skin colors? If we all came from “Mother Eve,” should we not all be the same color? In the past, some people suggested that people of other races were not really human, and they used that argument to justify everything from slavery to infanticide. What is the truth about race and skin color?

It is interesting scientifically that only humans have mostly naked skin and along with that, different colors of skin. Other animals have hair and mostly light-colored skin. As science has told us more about skin color and confirmed that we all came from common ancestors, we find clues about race and skin color and how we should treat one another.

The most fundamental reason for skin color differences is the fact that humans live at different latitudes. It is quite evident that human populations that have lived near the equator for many generations tend to have darker skin. As one moves from equatorial Africa toward the north, there is a constant change in skin color. By the time you get to northern Scandinavia, you have very light-skinned people with blond hair and blue eyes. People living near the equator have black skin, black eyes, and black hair.

It’s easy to understand why. Take two tin cans and paint one black and the other white. Fill them with boiling water and measure their temperature five minutes later. Dark colors radiate heat faster than light ones, so the darker can will be cooler than the white one. In equatorial Africa, the problems of heat release are very significant, because our brain cannot be allowed to overheat.

Another factor is ultraviolet radiation from the Sun, which can cause many changes in living tissue, including cancer. Human skin produces a substance known as melanin for protection. Melanin, God’s sunscreen, is a large organic molecule which both physically and chemically reduces the effects of UV radiation. Melanin absorbs UV rays causing them to lose energy. It also neutralizes harmful chemicals called free radicals that form in the skin after damage from UV radiation.

Dark skin absorbs a high percentage of UV light. It is essential, however, not to lose all the UV. Another thing that UV light does is to allow the body to produce vitamin D. Farther from the equator, the amount of UV is less, so dark-skinned people may not get enough UV light to make vitamin D. Lack of vitamin D causes rickets, so lighter skin is better at latitudes away from the equator.

As humans have migrated all over the globe, their ability to produce nutrients like vitamin D has been reduced in some groups. The Inuit people in Alaska don’t get enough vitamin D from the Sun, but they eat fish, which is very high in vitamin D. Their diet compensates for the low UV exposure. The presence of melanin in the skin, the complex biochemical system that produces vitamin D, and the ability of the body to protect itself against overheating and nutritional problems all speak well of the wisdom and design of our bodies.

Psalms 139:14 says, “I will praise you, Lord, for I am fearfully and wonderfully made.” Instead of allowing race and skin color to divide and cause hostility between us, we should celebrate God’s wisdom and design. They show that we have a universal Creator who designed and equipped us marvelously to live on a planet that has varied conditions and environments.

Elephant Ecology or Extinction

Elephant Ecology or Extinction There are those who like to change things, even if they have not investigated all the ramifications of that change. When God’s creation is involved, there are especially drastic proposals that are sometimes a product of ignorance. There is an ongoing battle between those who want to preserve elephants as a species and those who say that elephants are an ecological disaster. Instead of elephant ecology, they believe that elephants need to travel the road to extinction.

Those who want to allow elephants to go the way of the dinosaurs say that the volume of plants they need to survive makes them too destructive to justify their existence. To support such claims, they show pictures of areas decimated by elephants and tell stories about the invasion of elephants into agricultural regions. Elephants, they say, have threatened the survival of whole communities of subsistence farmers by eating the plants humans depend on.

On the other side of the fence is the “Save the Elephant” campaign in Kenya. They maintain that there is interconnectivity in the natural world between all organisms. They argue that elephants provide a variety of connections to various African ecologies. Elephants are ecosystem engineers. Scientists tell us that elephants knock over trees, trample brush, prune branches, and disperse seeds, which increases the biodiversity of the areas in which they live. Elephant ecology helps to maintain the savannas and forests.

A recent discovery connects the largest animals in the African ecology with the smallest. Herpetologist Dr. Stephen Platt has been studying the Nay Ya Inn wetland in Myanmar (Burma). He found that frogs depend on elephants in a very surprising way. As elephants travel in wetland areas, they leave Jacuzzi-size pools in the ground that stay full of water during the dry season. Frogs depend on these pools to lay eggs and develop tadpoles to maintain their populations in a fragile environment. Platt says there other small organisms that also depend on these pools for their survival. In Platt’s words: “Such microcosms of life are probably commonplace, but almost no one has bothered to look before.”

Earth’s history has been full of examples where large animals supported an ecosystem that produced not only life, but also resources for humans. Dinosaurs were huge for a reason, and it was not to make movies. Like the elephant, dinosaurs provided for humans by being the ecosystem engineers of their day. Without them, we would not have the coal, gas, iron, and many other resources that make our modern world possible.

God has provided for us in some incredible ways, and elephant ecology has opened our minds to a whole new way of seeing that.

Happiness Is a Fat Gecko

If you are an American and want to read a book that will make you appreciate life in the United States of America, this book is for you. Happiness Is a Fat Gecko will make you realize how blessed you are not to live in a developing nation.

I have known Dr. Frank Black for a very long time, and have appreciated his dedication to the Lord. Dr. Black worked in the emergency room of Methodist Hospital in Indianapolis, Indiana, for 19 years. He had been looking for ways to use his medical training and his Christian faith together where they were most needed. In 1992 he and his wife Lou Ann moved to Africa and lived in Chimala, Tanzania, where they worked for five years. This book tells the story of their experiences.

Happiness Is a Fat Gecko does not belittle or denigrate Africa or Tanzania, but in my opinion, it is a strong apologetic for the validity of the Christian system. The relationship of humans to nature and the value of the moral laws that Christ taught are contrasted with witchcraft, sorcery, and native medicine. The fact that a doctor would leave one of the largest hospitals in the United States where he could have money and power, to go to a country where there was a shortage of even basic medical equipment, and local people rely on shamans, is a strong example of what Christianity is all about.

The title Happiness is a Fat Gecko comes from the fact that Geckos (small lizards) are welcomed into the houses where Dr. Black worked. The reason is that they eat mosquitoes, and malaria is a major plague in Tanzania.

The book is well written, easy to read, and hard to put down. There are 48 short chapters, and each chapter contains humor, personal stories, and feelings from Dr. Black. We spend way too much time and energy fussing with each other over things that don’t have much relevance to the majority of people in the world. People like Frank Black do things that have eternal significance without a lot of recognition. I am sure this book will affect you as it did me. I recommend it highly.
