sustainable development” and “enlightenment for sustainable manner of life”. In practice, these terms can beconsidered to be equal. In this, the following principles are followed:principle of citizenship of the Earth (responsibility of an individual for the community and the planet);principle of respect for other people (consequence of seemingly harmless procedures – export of hazardouswaste, introduction of GMOs);precautionary principle (effects of interventions in the environment can never be fully predicted);principle of reasonable consumption (products harmless to health and nature);principle of actual effectiveness (the highest possible use of renewable source, effective technology of wasteprevention, etc.);principle of respect for life (i.e. not only human);principle of own responsibility (freedom and ownership without responsibility are empty terms);principle of self-restraint (voluntary restraining of material consumption)Educational events in the area of the environment for teachers are concerned particularly with exchange ofexperience between teachers, methodical assistance to teachers (practical instructions and instigations, didacticprocedures, use of instruments, etc.), technical knowledge of ecology and conservation biology, environmentalprotection and nature conservation, crafts and handicraft activities. All the above is carried out by means ofseminars, field excursions, ecopedagocially oriented teachers, conferences and other means.Emissions - the release of greenhouse gases and/or their precursors into the atmosphere over a specifi ed areaand period of time (UNFCCC).Emission sinks - processes absorbing the given substance (mostly carbon dioxide) from the airEndemic species - a plant or animal species which is present mostly on a very limited area (its distributionrange is territorially very limited).Energy industry - includes all processes of obtaining, processing, transport, transformation and fi nal use ofenergy resources in all sectors of economy.Eutrophication - gradual enrichment of soil and water by organic nutrients, particularly nitrogen andphosphorus. Natural eutrophication is a process lasting thousands or tens of thousands of years; however, it canbe substantially accelerated by human activities.Evapotranspiration - total evaporation of water from the surface of soil and from the surface of plants includingwater vapour released by plant stomata.Expansive plants - geographically indigenous plants with a high competitive capacity which excessivelyspread in their area or penetrate to an area where they previously have not been present; their spreading leadsto suppressing of biodiversity in the affected ecosystems.Expansive species - species with a tendency to expand the distribution range (area of expansion) or the areaof its habitat (Collared Dove - Streptopelia decaocto).Explantate culture - cultivation of tissues, organs or cells in an artificial nursery medium in vitro; synonym:tissue culture.Extreme climate phenomena - climate phenomena that fall outside the 10 th and 90 th percentile.FFlood - substantial temporary increase in the level of a water course caused by a sudden increase in the flowrate or a temporary decrease in the capacity of the channel.Floodplain meadow - a botanical formation of plants consisting of high herbs; geology of a body of sedimentsthat are deposited during fl oods.Forest line - the boundary of forest stands that is determined by climatic conditions limiting the occurrence offorest given the elevation.Forest vegetation zone - vegetation zone with a determining wood component of a tree height.Fossil fuels - natural substances rich in energy content whose combustion yields heat.
