Most serious of all, the slick could do irreparable damage to plankton and other algae. At the bottom of the ocean food chain, these simple organisms, directly or indirectly, provide sustenance -to say nothing of life-giving oxygen -for all the creatures higher up on the ladder of marine life. The Breton seaweed crop, grown for the pharmaceutical, textile and food industries, represents 90% of France's seaweed production and 75% of Europe's. This year's crop has been heavily damaged...
Instead, U.S. experts believe, the Russians needed a relatively large reactor to power a high-frequency radar carried aboard the satellite. The Soviets are thought to be trying to develop a radar sharp enough to detect changes in the pattern of plankton life near the oceans' surfaces. Such alterations are caused by the wake of deep-running subs, and thus could betray the presence of the previously untrackable U.S. nuclear deterrent...
...evolutionary terms, Seascape is a very convincing plug for the amoeba, or perhaps just plain plankton...
...cause a 10% reduction of ozone in the layer by 1990. That would result in a substantial increase of ultraviolet radiation on the earth, causing at the very least a greater incidence of skin cancer among humans. It might also disrupt the food chain by affecting food crops and plankton in the oceans. Lastly, the depletion of the ozone layer might have certain incalculable consequences like changing the earth's weather patterns...
Woods Hole Marine Biologist John Ryther has devised an even more ingenious aqua-farming scheme using partially treated sewage water from the Cape Cod town of Wareham. In his ponds, Ryther raises a thick harvest of plankton, which is then fed to baby oysters. To remove whatever ammonia, phosphates or nitrates the oysters and plankton may have left behind, he runs the sewage water over beds of seaweed, which also thrives on these chemicals...
