| overfishing (Taking out of the sea more than natural population growth can sustain. Overfishing has a number of causes, the most ruthless being "chronic over capacity" of modern fishing fleets to effectively take far more fish than can be replaced) | žuvies pergaudymas | |
| overfishing | pergaudymas | |
| overflow (outlet, Any device or structure that conducts excess water or sewage from a conduit or container) | pralaida | |
| overgrazing (Intensive grazing by animals, for example cattle, sheep or goats, on an area of pasture. It has become a serious threat to the world's rangelands and grasslands. Several factors have led to overgrazing, which leads to the soil being degraded and becoming liable to erosion by wind and rain, and even to desertification. The main pressures leading to widespread overgrazing have been the need to increase the size and numbers of herds to produce more food for an increasing human population, and the transformation of traditional pasture land into plantations to grow cash crops. Throughout the dry tropics, where traditionally herds ranged over vast areas, intensive livestock-rearing schemes have taken over, mostly to provide meat for the export market. Well-digging operations have also led to heavy concentrations of animals in small areas) | per didelis nuganymas | |
| overhead power line (Suspended cables by which electrical power is distributed throughout a country) | pakabinami elektros laidai | |
| overpopulation (A population density that exceeds the capacity of the environment to supply the health requirements of the individual organism) | per didelis žmonių tankumas | |
| overturn (The circulation, especially in the fall and spring, of the layers of water in a lake or sea, whereby surface water sinks and mixes with bottom water; it is caused by changes in density differences due to changes in temperature, and is especially common wherever lakes are icebound in winter; limnology) | cirkuliacija | |
