Human Impacts on the Environment
Flashcards do conjunto (15)
- 1Vegetation Food ProductionMachinery= Soil erosion
Synthetic fertilisers= inorganic
Monoculture= one species cultivated
Insecticides
Herbicides - 2Animal Food ProductionSelective breeding
Artificial insemination
Overbreeding - 3Farming and Living SpaceDeforestation= CO2 emissions
Disrupted food chains - 4Marine PollutionOil spills
Untreated sewage
Eutrophication and algal bloom - 5Vegetation Food ProductionMachinery= soil erosion
Synthetic fertilisers= damage soil structure
Insecticides= biomagnification, neurotoxic
Monoculture= growth of one specific species= less biodiversity
Herbicides= synthetic fertilisers= disrupt plants' metabolic pathways
Fertilisers= eutrophication - 6DeforestationGreenhouse effect= more CO2
Affects water cycle (less rainfall)
Flooding= soil erosion
Habitat fragmentation= extinction
Animal migration= changes food chain and population density - 7Animal Food ProductionSelective breeding/artificial selection
Artificial insemination
Contraceptive pills
Methane emissions
Aquaculture
Captive breeding - 8Extraction of Natural ResourcesCombustion of fossil fuels= air pollution
Drilling and mining= permanent habitat destruction/soil erosion
Extraction of sand= changes composition of sand, and flow and volume of water. - 9Food ChainsHabitat damage
Migration of animals
Deforestation
Excessive grazing
Hunting and poaching
Contribute to disruptions of the food chain
Less large animals= prey thrive
Less small animals= no food for predators - 10Marine PollutionOil spills
Untreated sewage
Careless disposal of rubbish= pollution
Heavy metal runoff= danger to marine life - 11Nuclear FalloutFrom nuclear power explosions
Radioactive particles= absorbed by organisms in the environment
Bio-accumulation= Cancer to higher trophic levels - 12Acid RainSulphur dioxide and nitrogen oxides react with water vapour in the atmosphere to form acids.
Rainfall p.H reduces from 5 (normal) to 4.2-4.4 (acidic)
Effects on soil= makes acidic, releases heavy metals and leaches its nutrients. - 13Human ImpactsClimate Change
Increased catastrophic disasters
Endangered and extinct animal species
Destroyed ecosystems - 14ConservationRe-afforestation
Recycling
Sewage Treatment
Conservation of Species
Controlling human activity= hunting and poaching - 15—
