| impacto ambiental de la acuicultura |
environmental impact of aquaculture (Fish farming pollutes the water with nutrients, methane and hydrogen sulphide which threaten both farmed fish and other marine life. Dangerous pesticides have been used to treat infestations of sea lice) |

| impacto ambiental de la agricultura |
environmental impact of agriculture (Agricultural activities have significant impacts on water quality, including increases in stream sedimentation from erosion, and increases in nutrients, pesticides, and salt concentrations in runoff. In certain regions, the misuse of pesticides has led to the development of pesticide-resistant strains of pests, destroyed natural predators, killed local wildlife, and contaminated human water supplies. Improper application of fertilizers has changed the types of vegetation and fish types inhabiting nearby waterways and rivers) |

| impacto ambiental de la energía |
environmental impact of energy (Energy and environmental problems are closely related, since it is nearly impossible to produce, transport, or consume energy without significant environmental impact. The environmental problems directly related to energy production and consumption include air pollution, water pollution, thermal pollution, and solid waste disposal. The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution. Diverse water pollution problems are associated with energy usage. One major problem is oil spills. In all petroleum-handling operations, there is a finite probability of spilling oil either on the earth or in a body of water. Coal mining can also pollute water. Changes in groundwater flow produced by mining operations often bring otherwise unpolluted waters into contact with certain mineral materials which are leached from the soil and produce an acid mine drainage. Solid waste is also a by-product of some forms of energy usage. Coal mining requires the removal of large quantities of earth as well as coal. In general, environmental problems increase with energy use and this combined with the limited energy resource base is the crux of the energy crisis. An energy impact assessment should compare these costs with the benefits to be derived from energy use) |

| impacto ambiental de la industria |
environmental impact of industry (The effects on the environment connected with industrial activities are mainly related to the production of industrial wastes that can be divided into various types: solid waste, such as dust particles or slag from coal; liquid wastes from various processes, including radioactive coolants from power stations; and gas wastes, largely produced by the chemical industry) |

| impacto ambiental de la pesca |
environmental impact of fishing (Fishing may have various negative effects on the environment: effluent and waste from fish farms may damage wild fish, seals, and shellfish. Fish farmers use tiny quantities of highly toxic chemicals to kill lice: one overdose could be devastating. So-called by-catches, or the incidental taking of non-commercial species in drift nets, trawling operations and long line fishing is responsible for the death of large marine animals and one factor in the threatened extinction of some species. Some fishing techniques, like the drift nets, yield not only tons of fish but kill millions of birds, whales and seals and catch millions of fish not intended. Small net holes often capture juvenile fish who never have a chance to reproduce. Some forms of equipment destroy natural habitats, for example bottom trawling may destroy natural reefs. Other destructive techniques are illegal dynamite and cyanide fishing) |

| impacto ambiental de la recreación |
environmental impact of recreation (Recreation and tourism are often accompanied by extensive damage to the environment. Aquatic ecosystems are particularly vulnerable to the effects of an increased tourist trade and the resultant building of hotel accommodations, sewage disposal works, roads, car parks and landing jetties on banks and coastlines; and the increased angling, swimming, water skiing, shooting or use of motor-boats in the water body. These all produce direct deleterious effects when conducted on a massive scale, including shore damage, chemical changes in the water, and sediments and biological changes in the plant and animal communities) |

| impacto ambiental de la silvicultura |
environmental impact of forestry (The world's forestry resources are shrinking at an alarming rate. The need for foreign exchange encourages many developing countries to cut timber faster than forests can be regenerated. This overcutting not only depletes the resource that underpins the world timber trade, it causes loss of forest-based livelihoods, increases soil erosion and downstream flooding, and accelerates the loss of species and genetic resources) |

| impacto ambiental de los hogares |
environmental impact of households (Household impacts on the environment include domestic heating emissions (hot air, carbon dioxide, carbon monoxide, water vapour and oxide of nitrogen, sulphur and other trace gases); domestic sewage consisting of human bodily discharges, water from kitchens, bathrooms and laundries; the dumping of bulky wastes such as old washing machines, refrigerators, cars and other objects that will not fit into the standard dustbin and which are often dumped about the countryside, etc.) |
