  • Habitat destruction is the process in which natural habitat is rendered functionally unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity.
  • Agriculture was the key implement in the rise of sedentary human civilization domesticate species created food surpluses.
  • When mining is not managed well the surface of an ecosystem can be destroyed, underground material can be introduced into a habitat, and when these materials are rained on a runoff containing high concentrations of metal ore or highly runoff that is highly acidic can be created and these are incredibly toxic to aquatic species.
  • Fire is another culprit that can fall under man-made or natural causes of habitat destruction. Human error or intent can result in forest fires. Lightning strikes can also result in serious fires. Earthquakes can physically move the land, and may be associated with subsequent tsunamis. Floods can destroy the vegetation and cause erosion of the land.The main cause of habitat destruction is the destruction of natural ecosystems in ... Whenever habitat destruction destroys a forest, it accelerates climate change.
  • everywhere, because of the explanation of human population we are destroying other animals' homes to more of our own.

  • Habitat DestructionBy: Britney Crumity
  • Thesis Statement• In this powerpoint,I will be talking about Habitat destruction can be destroyed directly by many human activities, most of which involve the clearing of land for other uses such as logging, agriculture, mining, and natural causes.
  • Habitat Destruction withlogging:•Wood andwood products•Large primetrees•Smaller trees•Forests
  • What is HabitatDestruction?•Natural homes•Humans•Die out•Animals homes•Plants•Less air for animalsand people
  • Causes of HabitatDestruction withAgriculture.•Humancivilization•Foodsurpluses•Species
  • Habitat destruction withmining:•Runoff•Aquatic species•Ecosystem•Highly acidic
  • Causes of Habitat Destruction with Natural Causes. •Fire •Climate Change •Floods •Earthquakes
  • Where is It Happening?• Habitat destruction• Human population• Animals homes
  • Pictures of Habitat Destruction
  • Conclusion• In this power point I have taught you about Habitat destruction as well as construction is completely in our hands. Habitat destruction has taken place due to our selfish needs and stupid uncontrollable mistakes. The main reason can be the ever-increasing population. As human beings needs increase, so does the deforestation. There is an ever- increasing demand for land and cutting down forests is the only solution.
