B19 | Human influences on Ecosystem

• An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
• biodiversity is the number of different species in an ecosystem. It is important because it provides food, shelter medicine and good biological health
• 3 main reasons for habitat destruction

  1. Increased area for food crop growth, livestock production, and housing
  2. Extraction of natural resources
  3. Freshwater and Marine pollution
• Deforestation

  • Flooding>There wont be any roots available to abosrb the water causing it to accumulate in the valleys
  • Habitat loss>Many plants/animals rely on forests for shelter and food
  • increase in CO2>When trees are cut down CO2 is released effecting greenhouse and global warming
• Species become endangered:

  • Habitat destruction
  • Hunting
  • climate change
  • Pollution
• How can endangered Species be conserved:

  • protecting vulnerable environments
  • increase biodiversity
  • captive breeding
  • increased public awareness.
