BIODIVERSITY THREATS


DEFORESTATION

Deforestation is the process whereby natural forests are cleared through logging and/or burning, either to use the timber or to replace the area for alternative uses.





The effects of deforestation are:




  • Reduced biodiversity
  • Release of greenhouse gas emissions
  • Disrupted water cycles
  • Increased soil erosion
  • Disrupted livelihoods

STATUS OF MARINE BIODIVERSITY

Marine biodiversity refers to a variety of life forms including plants, animals and microorganisms , the genes that they contain and the ecosystems that they form.




                                           



The threats of marine biodiversity are:

  • Over exploitation
  • Pollution
  • Habitat destruction and fragmentation
  • Non-native species invasion
  • Global climate change
