, Humans affect on
land and resourc
• Deforestation – land is cleared for farming
burning trees releases CO2, reclaimed lan
not fertile leading to increased use of fert
• Housing – biodiversity is lost
• Metal resources – quarrying and mining ca
destroy natural habitats, non sustainable
• Fossil fuels – includes peat bogs (big store
carbon and when they are burned carbon
released into the air – being destroyed fas
than new peat is being grown)
