<Li> The term bio-recycling appears in a 1976 paper on the recycling of organic carbon in oceans: "Following the actualistic assumption, then, that biological activity is responsible for the source of dissolved organic material in the oceans, but is not important for its activities after death of the organisms and subsequent chemical changes which prevent its bio-recycling, we can see no major difference in the behavior of dissolved organic matter between the prebiotic and post-biotic oceans ." </Li> <P> Water is also a nutrient . In this context, some authors also refer to precipitation recycling, which "is the contribution of evaporation within a region to precipitation in that same region ." These variations on the theme of nutrient cycling continue to be used and all refer to processes that are part of the global biogeochemical cycles . However, authors tend to refer to natural, organic, ecological, or bio-recycling in reference to the work of nature, such as it is used in organic farming or ecological agricultural systems . </P> <P> An endless stream of technological waste accumulates in different spatial configurations across the planet and turns into a predator in our soils, our streams, and our oceans . This idea was similarly expressed in 1954 by ecologist Paul Sears: "We do not know whether to cherish the forest as a source of essential raw materials and other benefits or to remove it for the space it occupies . We expect a river to serve as both vein and artery carrying away waste but bringing usable material in the same channel . Nature long ago discarded the nonsense of carrying poisonous wastes and nutrients in the same vessels ." Ecologists use population ecology to model contaminants as competitors or predators . Rachel Carson was an ecological pioneer in this area as her book Silent Spring inspired research into biomagification and brought to the worlds attention the unseen pollutants moving into the food chains of the planet . </P> <P> In contrast to the planets natural ecosystems, technology (or technoecosystems) is not reducing its impact on planetary resources . Only 7% of total plastic waste (adding up to millions upon millions of tons) is being recycled by industrial systems; the 93% that never makes it into the industrial recycling stream is presumably absorbed by natural recycling systems In contrast and over extensive lengths of time (billions of years) ecosystems have maintained a consistent balance with production roughly equaling respiratory consumption rates . The balanced recycling efficiency of nature means that production of decaying waste material has exceeded rates of recyclable consumption into food chains equal to the global stocks of fossilized fuels that escaped the chain of decomposition . </P>

Processes that help balance the ecosystems such as balancing nutrient cycling are known as
