" Another misconception is that we don’t need to worry about the local supply of insects because insects are everywhere all the time. If this is true, where do all those insects come from and what do they eat? Do they just appear out of nowhere? Is Aristotle’s theory of spontaneous generation alive and well in our popular culture? I hope not. The fact is that all insects, every last one of them, are produced directly or indirectly by plants. They either eat some plant part, or they eat another animal that ate some plant part. What follows logically, then, is that when we reduce the amount of plants in any given place, we reduce the diversity and abundance of insects. Alarming headlines from around the world are reminding us of the critical linkage between plants and insects; we have removed more than half of the forests on earth and, not surprisingly, insect populations have declined globally by at least 45% since 1979 "
