Stagnant water can be contaminated with human and animal feces, particularly in deserts or other areas of low rainfall. [2] Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types:
Animal agriculture, in particular meat production, can cause pollution, greenhouse gas emissions, biodiversity loss, disease, and significant consumption of land, food, and water. Meat is obtained through a variety of methods, including organic farming , free-range farming , intensive livestock production , and subsistence agriculture .
