Another example of environmental imbalance, caused by human action, is caused by the production of ethanol from ca-on-cane. Did you know that for every liter of alcohol produced in distilleries are also manufactured more than 12 liters of effluent? It is a highly polluting organic residue called vinasse. Incredible as it is not the alcohol that contributes to reduce pollutants of atmospheric air? When the stillage is released into a river, cause imbalance in the ecosystem because it causes an exaggerated increase in organic matter in water. Thus, the bacterial population rises and begins to consume much more oxygen dissolved in water, and the absence of oxygen, therefore, ends up killing the fish. Currently, they only used 5% of vinasse as fertilizer. Greater reduction of pollutant discharge this organic matter would cause the oxygen in the water was replenished bringing balance back to the river. New technologies are developed to minimize aggression caused to the environment. The production of alcohol is a good example, because it is a fuel produced on a large scale, less polluting than gasoline and is a renewable resource. With this, we are reducing air pollution and carbon dioxide, but producing vinasse, which is an industrial waste pollutant. The relationship between balance and imbalance is always present throughout questioning bringing environmental questions and concerns, but decision making should always focus on the one that will cause the least possible environmental impact.

Drugi primjer ekološke neravnoteže, uzrokovane ljudskim djelovanjem, je uzrokovana proizvodnju etanola iz CA- na-trske. Jeste li znali da je za svaku litru alkohola proizvedenog u destilerije su proizvedeni više od 12 litara otpadnih voda? To je vrlo zagađuje organskog ostatka naziva vinasse. Nevjerojatno, jer nije alkohol koji pridonosi smanjenju zagađivači atmosferskog zraka? Kad stillage je pušten u rijeku, uzrokuje neravnotežu u ekosustavu, jer to uzrokuje pretjerano povećanje organske tvari u vodi. Dakle, bakterijska populacija raste i počinje konzumirati puno više kisika otopljenog u vodi, i nedostatak kisika, dakle, završava ubija ribu. Trenutno se koristi samo 5% vinasse kao gnojivo. Veće smanjenje ispuštanja štetnih tvari u tom organske tvari izazvati kisika u vodi je dopunim donosi ravnotežu natrag u rijeku. Nove tehnologije su razvijeni kako bi se smanjili agresiju nanesenu okolišu. Proizvodnja alkohola je dobar primjer, jer je gorivo koje se proizvodi u velikim razmjerima, manje zagađuje od benzina i obnovljivi resurs. Uz to, mi smo u smanjenju zagađenja zraka i ugljični dioksid, ali vinasse proizvodnju, što je industrijski otpad zagađivač. Odnos između ravnoteže i neravnoteže je uvijek prisutan tijekom ispitivanja donosi ekološka pitanja i nedoumice, ali odlučivanje uvijek treba usredotočiti na onu koja će uzrokovati najmanje mogući utjecaj na okoliš.
