We have had the great pleasure of presenting our lectureships in Australia. One of the common questions from college groups has been, “What good are termites?” The termite mounds in some places we saw were over 10 feet (3 m) tall. People frequently complained that they couldn’t build structures out of wood. There were so many termites that the wood didn’t last long enough to make it cost effective.
Science News (February 16, 2019, page 4) carried an interesting article about termites. Kate Parr is a tropical ecologist from the University of Liverpool in England conducting research for the university and the Natural History Museum in London. She has been examining how ants and termites affect the decomposition and consumption of organic material in rainforests.
As they conducted their study, the research area went through a drought. During the drought, termite numbers doubled, and decomposition rates increased dramatically. They found that during the drought in areas where termites were not disturbed, and their numbers increased there was a greater amount of soil moisture, more nutrient mixing, and better seedling survival rates. Areas where the termites had been eliminated had massive die-offs of plants which affected the animal population. In times of normal moisture with no drought conditions, there was no difference in all these variables. What good are termites? It seems apparent that the termites allowed life to prosper during droughts. In places like the Australian outback, the presence of termites is apparently vital for the avoidance of drought die-offs.
One aspect of design in the cosmos is the fact that there always seem to be animals that serve a unique roll in an area when destructive agents threaten the balance of the ecology. The role of insects and small life-forms in the existence of life on Earth is an area that is very understudied. But new discoveries are coming fast and furious as we see the designs of God allowing life to exist even under the most severe environmental conditions.
