We have allowed these chemicals to be used with little or no advance investigation of their effect on soil, water, wildlife, and man himself. Future generations are unlikely to condone our lack of prudent concern for the integrity of the natural world that supports all life.

There is still very limited awareness of the nature of the threat. This is an era of specialists, each of whom sees his own problem and is unaware of or intolerant of the larger frame into which it fits. It is also an era dominated by industry, in which the right to make a dollar at whatever cost is seldom challenged. When the public protests, confronted with some obvious evidence of damaging results of pesticide applications, it is fed little tranquilizing pills of half truth. We urgently need an end to these false assurances, to the sugar coating of unpalatable facts. It is the public that is being asked to assume the risks that the insect controllers calculate. The public must decide whether it wishes to continue on the present road, and it can do so only when in full possession of the fact. In the words of Jean Rostand, "The obligation to endure gives us the right to know."

They were generalists. Those primitive early cockroaches possessed a simple and very practical anatomical design that remains almost unchanged in the cockroaches of today. Throughout their evolutionary history they have avoided all wild morphological experiments like those of their relatives, the mantids and walking sticks, and so many other bizarrely evolved insects. For cockroaches the byword has been: Keep it simple. Consequently, today, as always, they can live almost anywhere and eat almost anything.

Unlike most insects, they have mouthparts that enable them to take hard foods, soft foods, and liquids. They will feed on virtually any organic substance. One study, written a century ago and still considered authoritative, lists their food preferences as "Bark, leaves, the pitch of living cycads (fern palms), paper, woolen clothes, sugar, cheese, bread, blacking, oil, lemons, ink, flesh, fish, leather, the dead bodies of other Cockroaches, their own cast skins and empty egg-capsules," adding that "Cucumber, too, they will eat, though it disagrees with them horribly." So much for the cucumber.

It is not that there is more to do, there is everything to do. Biological science, with medicine bobbing somewhere in its wake, is under way, but only just under way. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the amplification of agricultural technology or the cultivation of nutrients in the sea. As we learn more about the fundamental processes of living things in general we will learn more about ourselves, including perhaps the ways in which our brains, unmatched by any other neural structures on the planet, achieve the earth's awareness of itself. It may be too much to say that we will become wise through such endeavors, but we can at least come into possession of a level of information upon which a new kind of wisdom might be based. At the moment we are an ignorant species, flummoxed by the puzzles of who we are, where we came from, and what we are for. It is a gamble to bet on science for moving ahead, but it is, in my view, the only game in town.
