The video discusses the varying availability of fresh water globally and the potential conflicts arising from scarcity. It highlights the impact of climate change on water resources and the increasing demand due to population growth and industrialization. The video explores the uses of fresh water, challenges like contamination, and strategies for water management, including reservoirs, desalination, and conservation. It also touches on legal aspects and case studies related to water conflicts.

What is a potential consequence of limited fresh water availability in certain regions?

• Conflict over water resources

• Improved water quality

• Decreased industrialization

• Increased agricultural output

How might climate change affect fresh water availability?

• It will decrease the need for irrigation

• It may alter rainfall patterns, affecting water availability

• It will reduce industrial water usage

• It will ensure equal distribution of water globally

What is a major use of fresh water in agriculture?

• To irrigate crops and prevent salinity

• To increase soil salinity

• To cool industrial systems

• To generate electricity

What can lead to the unsustainable use of fresh water supplies?

• Sustainable abstraction

• Pollution and over-extraction

• Increased rainfall

• Natural lake formation

Which method is used to remove salt from water to make it fresh?

• Rainwater harvesting

• Desalination

• Canal construction

• Aquifer recharge

What is a benefit of recharging aquifers?

• Immediate increase in water supply

• Reduction in water demand

• Elimination of water pollution

• Long-term sustainability of water resources

What is a challenge associated with rainwater harvesting?

• It depletes aquifers

• It requires desalination

• It increases water pollution

• It is illegal in some states

What is a downside of using reservoirs and dams for water storage?

• They increase water salinity

• They are inexpensive to build

• They cause water pollution

• They lead to habitat loss and evaporation

Why is water redistribution considered expensive?

• Water is heavy and costly to move

• It leads to increased rainfall

• It requires desalination

• Water is light and easy to transport

What is a current trend in desalination technology?

• It is reducing water demand

• It is becoming less feasible

• It is becoming more expensive

• It is improving and becoming more feasible
