Freshwater Systems Quiz

What are the three crucial functions of fresh water for life on Earth?

• Transporting sediments and nutrients, sustaining ecosystems, and providing drinking water

• Supporting plant life, creating food chains, and replenishing aquifers

• Providing a home for millions of creatures, shaping landscapes, and fertilizing farmlands

• Generating renewable energy, supporting agriculture, and preventing floods

What is the current state of freshwater wildlife?

• Vanishing faster than wildlife in any other habitat

• Thriving and increasing in population

• Becoming more resilient to climate change

• Adapting well to human activities

What is the main challenge in restoring freshwater systems?

What is the advantage of using renewable energy over building mega hydropower dams?

• Renewable energy is cheaper and more efficient

• Renewable energy has a smaller impact on freshwater flow

• Renewable energy does not require the displacement of communities

• Renewable energy does not harm the environment

How can dams be modified to reduce their impact on freshwater flow?

• Increasing the number of dams to regulate flow

• Building dams in main river channels

• Blocking the flow of rivers completely

• Releasing larger volumes of water at the right time

What is the most effective way to conserve freshwater in agriculture?

How can technology help reduce pressure on freshwater systems in industry?

• By increasing water extraction for industrial use

• By building more dams for industrial water storage

• By recycling water and using clean energy

• By diverting water from rivers to industrial areas

What is the potential outcome if we work with the freshwater flow?

• Wildlife will disappear from freshwater habitats

• Rivers and wetlands will become healthier

• Cities will become more vulnerable to flooding

• Freshwater fish stocks will decline rapidly

How can cities protect themselves against flooding?

• Removing wetlands and riverbanks

• Diverting rivers away from urban areas

• Constructing green walls and roofs

• Building more dams and barriers

What is the vision for the future of freshwater systems?

• To rely solely on renewable energy for water supply

• To extract and store as much water as possible

• To treat freshwater as a limitless resource

• To restore and maintain the natural flow of freshwater
