7 Questions
Match the following environmental issues with their causes:
Ozone depletion = CFCs from spray cans, refrigerators, and industrial detergents Eutrophication = High levels of nitrogen and phosphorus from animal slurry Vermin and odours at waste disposal sites = Waste attracting rats and gulls Groundwater contamination from waste disposal = Unsuitable items left at dumps
Match the following environmental problems with their solutions:
Overfishing = Setting fish quotas Pollution in fisheries = Reducing pollution to allow migratory fish to reach breeding grounds Contamination of groundwater from waste disposal = Preventing unsuitable items from being left at dumps Ozone depletion = Reduction in use of CFCs and using HFCs instead
Match the following waste management practices with their importance:
Bioremediation = Removing pollution and allowing areas to revert to their unpolluted state Waste minimisation = Conserving resources by reducing waste at the source Slurry management = Improving water quality by controlling the release of nutrients into rivers and lakes Microorganisms in waste management = Breaking down organic waste and destroying pathogens
Match the following human activities with their resulting environmental issues:
Clearing land for farmland = Reduction in biodiversity Use of insecticides to control pests = Loss of natural predators and useful organisms Dumping and sewage disposal = Pollution Overuse of fertilizers and disposal of farm wastes = Agricultural pollution
Match the following types of pollutants with their sources:
Volcanic emissions and smoke from forest fires = Natural pollutants Household wastes = Domestic pollution Sprays to control pests and weeds = Agricultural pollution Radioactivity and noise = Human activities
Match the following environmental impacts with their causes:
Superabundance of food for a small number of organisms = Clearing land for farming Resistance of microorganisms to antibiotics = Use of insecticides to control pests Global warming = Human activities Upset balance of nature due to insecticide effects = Application of insecticides to control pests
Match the following ecosystems with their affected elements of pollution:
Air, freshwater, sea, and soil = Pollution Disposal of farm wastes such as slurry and silage effluent = Agricultural pollution Litter and noise = Pollutants from human activities Smoke from forest fires = Pollutants from natural sources
