New cards

What events/activities are threatening biodiversity?

  • human population growth

  • deforestation

  • agriculture

  • climate change

  • monoculture

2
New cards

How does deforestation reduce biodiversity?

  • destruction of trees - decreases species biodiversity

  • destroys habitats = further reduction of species

  • decreased population size of species = loss in alleles

  • increased soil erosion = decreased nutrients available in soil = less plants survive

  • largely human induced

3
New cards

What agricultural techniques lead to reduction in biodiversity?

  • removal of hedgerows

  • use of chemical pesticides and herbicides (loss of species diversity and potential loss of pollinators)
