Extinction of Plant and Animal Species

Near the end of 2023, the U.S. Fish and Wildlife Service removed 21 species from the Endangered Species Act because they have become extinct. What causes the extinction of plant and animal species?

Many factors lead to extinctions. Dr. Hugh Ross says the fossil record indicates that half of the mammal species that existed at the time of Adam and Eve are now extinct. Human activities that can endanger species include habitat destruction, introduction of invasive species, and introduction of diseases. Of course, animals can endanger people in various ways, including introducing diseases.

Humans have endangered plant species by introducing invasive plants. Plants used for decorative purposes can become invasive. Examples are English holly and the tree of heaven. Some plants that have become invasive were introduced to serve a purpose, such as controlling erosion. An example is the kudzu plant.

At other times, humans have caused extinction by killing large numbers of a species such as the passenger pigeon. Because of hunting and habitat destruction, the dodo bird became extinct within less than a century of its discovery. Humans caused the extinction of the great auk by foolish vandalism. Today, poachers are endangering the rhinoceros by killing them for no good reason. By contrast, human efforts rescued the California condor after it became extinct in the wild.

Woolly mammoths existed alongside early humans, and some scientists say they were essential for the survival of humans in some areas. People used them for food and their skins for protection from the elements. Their bones became tools, building materials, and even musical instruments. These large animals also kept plant vegetation under control while spreading their seeds. We can not always determine the cause of the extinction of plant and animal species, and that is the case with woolly mammoths.

The extinction of the dinosaurs occurred before humans were on the scene. That is good because humans and dinosaurs could not coexist on the land or at the same atmospheric oxygen level. God used them to prepare Earth for humans, and He orchestrated their extinction before He placed Adam and Eve in the garden.

As we look at the extinction of plant and animal species, we learn some essential facts. From the beginning, God had a plan for life as He prepared this planet for us to be here. He gave the first humans the responsibility to take care of the Earth, but we have not done a very good job. Finally, God is still giving us a chance to do better, and we have had some successes. Serving God involves serving others and caring for what God has given us for human flourishing. We can only do that when we submit to His plan for our lives.

Great Auk and Human Stewardship Failure

Great Auk and Human Stewardship FailureIt was a flightless North Atlantic bird that stood upright 30-33 inches (75-85 cm) tall and weighed 11 pounds (5 kg). Its small wings were less than 6 inches (15 cm) long. It’s also the story of the great auk and human stewardship failure.

The fact that the great auk couldn’t fly and that it was large enough to provide a meal for hungry sailors is a major reason why it became extinct. People also killed them for their feathers. As the great auk was nearing extinction, people killed the last ones to stuff their skins and display them as trophies in museums and private collections.

Though the great auk couldn’t fly in the air, it did fly underwater. Some might say this bird was poorly designed with its large body and small wings. But underwater, those wings became fins to pursue and catch fish. Larger wings would have been a hindrance underwater. The large size of this bird gave evidence that it found abundant food and had no need to fly in the air.

Great auks had few predators, but since they couldn’t fly and were slow on land, they became easy prey for humans. When it was evident that they were becoming extinct, great auks became more valuable. Collectors wanted a stuffed bird for a trophy, and museums wanted one for display. At last, there was only one breeding pair and one egg left on Eldey Island off the coast of Iceland. On July 3, 1844, three men climbed up on Eldey Island, killed the last two birds, and smashed the egg. The great auk was no more.

The picture shows a monument to the great auk in Iceland facing toward Eldey, the rocky island where the birds made their last stand. It tells the sad story of the great auk and human stewardship failure. God gave humans the duty to care for His creation. He commanded Adam and Eve to “rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground” (Genesis 1:28). Jesus told us that God cares for the birds. (See Matthew 6:26 and Luke 12:6.) The Apostle Paul in Romans 13:4 talks about human rulers. He wrote that they are “God’s servants for your good.” I think we can apply that concept of rulers to our duty toward the living creatures God created. We are stewards entrusted with caring for the world God gave us, including the living creatures.

Today there is a lack of regard even for human life. For the sake of convenience, people kill babies before they are born. Others set out to kill as many people as possible using guns or vehicles. The great auk and human stewardship failure is a reminder of how many times humans have failed to keep God’s commands. “But God, who is rich in mercy, because of his great love that he had for us, made us alive with Christ even though we were dead in trespasses. You are saved by Grace!” (Ephesians 2:4-5 CSV).
