Overpopulation
Environmental problems
Depletion
Pollution
Climate change
raw materials for example
machines, devices, houses
Fossil fuels
gas, petrol, diesel
depletion
pollution
Air
Water
Soil
nitrogen -stikstof
Fertiliser and traffic → nitrogen in soil/water/air
→ lots of nettles and grasses, little biodiversity
Air pollution = smog/fine particulates (fijnstof)
soil pollution
toxic waste → roots → food chains
water pollution
Wastewater (agriculture, industry, households, ships)
→ toxic substances in the water
Harmful to organisms + humans!
worksheet
Versterkt broeikaseffect
Broeikasgassen (zoals CO₂) houden warmte vast
Door meer CO₂-uitstoot is het broeikaseffect sterker geworden.
Gevolg: opwarming van de aarde
gevolgen klimaatverandering
Zeespiegel stijgt → laaggelegen gebieden (zoals Nederland) kunnen overstromen.
Meer blauwalg in water → giftig, zwemmen soms verboden.
Meer droogte en verzilting → landbouw moeilijker.
Sommige mensen moeten verhuizen door stijgend water of voedseltekorten.
