Spreading Life Throughout the Earth

Spreading Life Throughout the Earth - Great Blue Heron
Great Blue Heron

An amazing fact is that the creation is designed for continually spreading life throughout the Earth. That isn’t always a good thing for humans.

Several years ago, a friend of mine built a large pond on his farm. He planned to stock the pond with desirable fish, avoiding carp and sunfish, which he considered to be trash fish. He stocked it with largemouth bass, and some minnows used as food for the bass. Later, when I was visiting him, I decided to do a little fishing in his pond. The first fish I caught was a large carp, and a whole school of sunfish converged on a grasshopper or worm I used as bait.

My friend was horrified and promptly wanted to accuse an enemy of putting trash fish in his pond. I noticed a great blue heron wading through the shallows of the pond picking off minnows, and immediately I knew how the sunfish got there. Herons wade through areas where fish have built nests of eggs during their spawn. The eggs are sticky and adhere to the Heron’s legs. When the Heron goes to another pond, it carries the fish eggs along.

Recent research has discovered another way in which fish are designed to spread from place to place. A study in Hungary has shown that some fish eggs can pass through the digestive system of a duck, and a small percentage of the eggs have baby fish still alive inside.

The wisdom of this system in the natural world is apparent. A new body of water will usually be sterile. To get a functional ecological system going, the bottom of the food chain must be established quickly. Birds are facilitators in getting a fish population in operation, and now we know of at least two ways they do it.

The implications for humans are significant. Biologists trying to keep a species of carp out of the Great Lakes have a huge problem. The design of fish and birds makes it almost impossible to keep any fish population isolated. God has created many designs for spreading life throughout the Earth, even into sterile places.

What Happened to the Teays River?

What Happened to the Teays River?Yesterday, we talked about the Teays River and how, like other rivers, it brought water into dry areas. (To read yesterday’s post, click HERE.) The map above shows the approximate path of the river and its tributaries. But we didn’t tell you what happened to the Teays River.

As glaciers came southward across North America, they buried the river and its tributaries with massive amounts of sand and gravel. In the process, the river’s flooding and flowing impounded massive quantities of water. The Teays still exists today in water stored underground. I can drill a well 12 feet (3.7 m) in my back yard and hit potable water. The agricultural blessing of the Teays has made the Ohio River Valley fertile and has allowed cities to exist in areas that are not blessed with great surface water. What happened to the Teays River is still affecting our lives today.

In addition to the benefits we mentioned yesterday, the flooding of rivers also spreads diverse plants and the wildlife that feeds on them. The biggest watermelon I have ever eaten I found on an island on the White River near Spencer, Indiana. A friend of mine who enjoyed it with me recognized the species of melon, and we eventually found the patch that it came from some 75 miles upstream. In our trips through the Grand Canyon, we have frequently found plant life not native to Colorado thriving on sand bars in the canyon. When our river here in Michigan flooded in February of 2018, a layer of black soil was laid down in my yard and the woods on the edge of my property. Now there are dozens of plants growing in that soil which are not native to Michigan. Animal life of all kinds eat many of those plants.

Rivers are the cleaners of both the land and the water. One interesting part of living on a river is watching what floats by – a log, a tree, human junk, and all kinds of minerals. When the river dumps its load in a delta or an alluvial fan, the minerals become available for human use. In the Colorado Plateau, an ancient river carried and deposited logs containing uranium. The water moved those logs and impregnated them with uraninite, a mineral used to obtain precious uranium for nuclear materials. In my college studies in geology and mineralogy, we learned how to “read” a river and use that information to locate critical materials for technology.

It is essential that we take care of our rivers. We need to understand rivers and recognize God’s design in creating a planet molded and shaped by flowing water. What happened to the Teays River was caused by ancient glaciers that carved the land and created the Great Lakes. What happens to our rivers today depends on us and our stewardship of what God has given us.

From Genesis to Revelation, we see rivers as critical elements in the story of human existence now and in the future. The most important river of all is described in Revelation 22:1-2: “And He showed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb. In the middle of the street of the City and on each side of the river was a Tree of Life bearing 12 crops of fruit and the leaves of the tree served as medicine for the healing of the nations. And there shall be no more curse: but God’s throne and the Lamb shall be in it.”
