Within, the rivers were lighted fluorescently an apparent anomaly that was due to the fact that the problems of shielding marine life from direct sunlight in such a shallow medium had not yet been worked out; while the opaque plastic that walled the laboratories within the rivers was a concession to their strength, since the clear plastic that would have provided aquarium walls for the lab and complete inspection for a constant and overall check of the ecological experiments had been overruled by U.N. Budget Control.
A continuous process of discovery, design and improvement was making accessible power of unimaginable magnitude—with, alas, ecological consequences equally unimagined at the time—especially through the use of cheap fuel and electricity. The “era of the railroad” was far advanced and steamships coursed the seaways of the world.
"My grandfather discovered this world better than four hundred years ago. He picked this area because it all could be comfortably included in Discovery Rights. It wasn't until years afterward that he realized the ecological peculiarities of this region." "He certainly capitalized on them." "There was plenty of opportunity. The plants and animals here are different from others in this world.
Presently he looked up the normal rate of increase, with other data, among herds of bivis domesticus in a wild state, on planets where they have no natural enemies. It wasn't unheard-of for a world to be stocked with useful types of Terran fauna and flora before it was attempted to be colonized. Terran life-forms could play the devil with alien ecological systems, very much to humanity's benefit.
Von Baer maintains that the depression of the Caspian was produced by a sudden subsidence, from ecological causes, and not gradually by excess of evaporation over supply. See Kaspische Studien, p. 25.
They will also face specific situations arising out of climate, access to raw materials, custom, habit and other ecological and cultural factors which differ profoundly from continent to continent, nation to nation, city to city and district to district in the same nation. Human communities have sought and found different means of dealing with the problems of community administration.

"And some non-Company people have gotten hold of it, and so had Interworld News. Why, even some of my people are talking about ecological side-effects. You know what will happen when a story like that gets back to Terra. The conservation fanatics will get hold of it, and the Company'll be criticized." That would hurt Leonard. He identified himself with the Company.
And naturally there were animals. There were even trees of severely practical design, and underbrush and ground-cover equivalent to grass. There was, in short, a perfectly predictable ecological system on Orede.
This ecological maze of rivers and eddies and balance tanks; of air jets and current and micro-life; of spin-rate-control and shielding, were all keyed to servo-regulated interdependence that for this self-contained world replaced the stability achieved in larger ecologies through survival mechanisms.
