Today on the airplane, I read this article about the many great possible uses for algae. Although most of us have always thought of algae as a yucky form of matter to avoid–as in pond scum–scientists and biotech innovators are increasingly experimenting with algae as a source of energy and as a basis for biodegradable plastics.
These promising innovations offer a perfect example of the statement from Tehillim (the Book of Psalms, 118:22), “The stone that the builders refused has become the corner stone.” The lowly pond scum which we’ve mostly sought to avoid or discard may become the source of promising solutions for our global energy and climate change problems.
