IN ONE CUBIC FOOT
In any environment - forest, mountain or water - you always see big animals first: birds, mammals, fish. But under your feet, on land or in water there are many smaller organisms: insects, tiny plants, miniature sea creatures. They seem unimportant, but, in fact, these sea creatures and ground dwellers are “the heart of life on the Earth”, say naturalist E.O Wilson. Without them, our world would change dramatically.
Most organisms on the Earth live on the ground or just below it. Here, they are part of an important cycle. Plants and animals fall to the ground when they die. Later, tiny insects and other organisms break down the dead plant and animal material. This process eventually returns nutrients to the soil and give plants energy. Plants can then help to maintain healthy environment for humans and other animals.
Despite their importance, scientists know very little about most ground organisms. To learn more, photographer David Liittschwager went to different places around the world, including a forest, a river, a mountain, and a coral reef. In each place, he put a green 12-inch cube on the ground or in the water. Then he and his team counted and photographed the organisms that lived in or moved through the cube. Often they discovered hundreds, some only a millimeter in size. “It was like finding little germs”, he says. In the coral reef in French Polynesia, he saw thousands of creatures in the cube and photographed 600. The team identified as many as possible, but it was difficult. Many of the animals they found were new species.
