Clean Water for All: The Power of Water Filters

The video discusses water scarcity, its causes, and solutions using green technology. It highlights the role of water filters in addressing the four main causes of water scarcity: insufficient water, dirty water, poor management, and distribution issues. The video explains how water filters work, including desalination plants and solar-powered filters, to provide clean water from various sources.

What are the four main causes of water scarcity mentioned in the video?

• Industrial waste, agricultural runoff, urbanization, and drought

• Overfishing, habitat destruction, invasive species, and pollution

• Lack of water, dirty water, poor management, and distribution issues

• Climate change, pollution, overpopulation, and deforestation

What is the primary function of a water filter as described in the video?

• To increase the water's temperature

• To remove dirt and contaminants from water

• To add minerals to water

• To change the water's color

How do desalination plants contribute to solving water scarcity?

• By cleaning polluted rivers

• By converting seawater into fresh water

• By storing rainwater for future use

• By reducing water usage in agriculture

What is a unique feature of some water filters that helps remove bad smells and tastes?

• Ultraviolet light

• Activated carbon

• Ozone treatment

• Chlorine tablets

How do solar-powered water filters help communities in sub-Saharan Africa?

• By providing electricity to pump water

• By using solar energy to remove contaminants from water

• By storing water during dry seasons

• By using wind energy to clean water
