Factors led to depletion of flora fauna

• A) Extensive use of fossil fuels
  Also all the carbon from the Hugh forest fires brought on by drought that is going on everywhere. The result of climate change.The tundra in the Artic is also melting which holds extremely large amounts of methane.Which is 20 times worst then burning fossil fuels is being released. So we are at the tipping point now of runaway global warming!
• 1. human consumption (food)
  2. destruction of natural habitat or niche
  3. climatic change
  4. pollution
  5. hibernation (which results to false alarm of extinction, think coelecanth)
  6. disruption of food cycle like loss of food (low end of food chain) which leads to starvation of animals
  7. increase in number of predators due to imbalance in the food cycle
  8. illegal capture and selling of wildlife in black markets
  9. consumption of plants and animals as raw materials for clothing and other usage.
  10. inability to reproduce as some flora and fauna are monogamous so if their partners die, they 
• Habitat loss
  Habitat degradation
  Habitat fragmentation
