sustaining ecosystems

• What was the main focus of the physical geography fieldwork?

  Investigating the River Darent
• What does Bradshaw's Model describe?

  How river characteristics change downstream
• Which key variables were measured in the fieldwork?

  Velocity, discharge, width, depth, bedload size
• How did the findings relate to Bradshaw's Model?

  They partially supported the model's predictions
• What change in bedload was observed downstream?

  Bedload became less angular and smaller
• What does attrition do to river material?

  Breaks down material as it moves
• What trend was observed regarding the gradient of the river?

  Gradient seemed to reduce downstream
• What technique was used to present data in the fieldwork investigation?

  Line graph
• Why was a line graph justified for presenting data?

  It clearly shows shape and depth variations

• How does mineral exploitation affect the Arctic environment?

  Leads to oil spills and habitat disruption
• What effect does overfishing have on the Arctic food web?

  Reduces populations of key species
• Who is affected by changes in the Arctic ecosystem?

  Indigenous communities relying on hunting
• What challenges do Indigenous communities face due to ecosystem changes?

  Threatened traditional lifestyles and habitat loss
• What is the overall impact of human activities on the Arctic ecosystem?

  Leads to biodiversity loss and environmental damage
• How does ecotourism benefit the Monteverde Cloud Forest?

  Contributes to conservation efforts and minimizes damage
• What economic benefits do local communities gain from ecotourism?

  Employment in tours, lodges, and projects
• How is revenue from ecotourism used in Monteverde?

  Funds conservation programs and research
• What ongoing challenges does Monteverde face regarding ecotourism?

  Infrastructure development and visitor regulation
• What is necessary for the long-term sustainability of Monteverde?

  Ongoing regulation to prevent overdevelopment
• Why are natural ecosystems important?

  They provide essential services and biodiversity
