. Lightning is Nature’s quickest and most efficient converter and recycler, instant manufacturer of nitrates, phosphates, sulfates; it burns anything on its path, recharges ions. Lightning sustains the needs of the biosphere, it is key to biodiversity.
2. Fire is the Nature’s second tool. While fire is indeed destructive, in the long run, fields, grasslands and forests are given new life by it. Fire is a test of survival of the fittest. It is the key to renewal and continuity of life.
3. Volcanoes erupt to recycle the elements from the bowels of the earth to replenish the spent landscape, so with submarine volcanoes that keep the balance of marine ecosystems.
4. Natural cycles prevail with the seasons, weather and climate. They govern the life cycle and alternation of generations of organisms; the food chain, food web, and food pyramid. The same applies to long term phenomena such as Continental Drift and Ice age.
5. Naturally occurring cycles govern the physico-chemical interactions of the earth’s chemical elements and compounds, principally Carbon, Hydrogen, Oxygen and Nitrogen (CHON), which are essential to life.
6. Nature recycling of organic materials in through the action of microorganisms: bacteria, algae, protists (amoeba, diatoms), fungi, blue green algae. Fibrous materials are broken down by fungi. Other than roughage and fuel, rice hay is used as substrate for mushroom growing. The spent materials decompose easily into organic fertilizer.

7. Biological (e.g. Trichoderma, a fungus, to hasten composting; termites on wood); Enzymatic reaction (e.g., wild sunflower in composting, urea in hay}; Mechanical (shedding, grinding); Fermentation (silage, retting, biogas digester)
8. Recycling by animals also helps in controlling the destructive ones such as the mosquito, which is food of fish, spider and bat.
9. Nature’s nutrient converters. Simple life forms such as lichens, algae, mosses and ferns silently work on inert materials, convert them into nutrients for higher organisms.
10. Nature’s recycling with waterways Mekong river in Vietnam (below), Pasig River in the Philippines, Great Britain, Danube and Rhine in Europe, the Nile, Mississippi, Amazon, Yangtze, Tigris-Euphrates. Rivers, lakes, swamps, basins – they provide many basic needs of man. They are arteries of life, the ecological bridge between the living and the non-living world. It is said that no civilization exists without a river.
Snails and crustaceans are nature's aquatic janitors.
Goats and pigs have tremendous appetite. They eat a wide range of food not suitable to other organisms.
Lake Tikob is a self-contained ecosystem,a natural sink.
