It concludes with a call to action for diversified water resource management.

What are some of the major threats to global water resources mentioned in the introduction?

• Overfishing and pollution

• Dead zones and acidic oceans

• Deforestation and urbanization

• Climate change and drought

What is the primary goal of the desalination process discussed in the video?

• To increase ocean salinity

• To convert saltwater into drinking water

• To desalinate groundwater

• To reduce water pollution

What is a significant challenge of desalination that the video addresses?

• Complexity of the process

• Lack of skilled labor

• High cost of materials

• Energy consumption

How does the energy recovery device help in the desalination process?

• It increases the salinity of the brine

• It harnesses energy from the brine to power pumps

• It filters impurities from the water

• It reduces the pressure needed for desalination

What environmental concern is associated with the discharge of brine from desalination?

• Harm to marine organisms

• Rising sea levels

• Depletion of fish stocks

• Increased ocean acidity

What did the studies on brine discharge aim to determine?

• The potential for desalination in arid regions

• The effect of high salinity on marine life

• The economic cost of desalination

• The impact of desalination on air quality

Why is it important to consider site-specific factors in desalination projects?

• To speed up the construction process

• To ensure uniformity across projects

• To minimize costs

• To address unique environmental and biological conditions
