Why fresh water is so important?
Freshwater is essential for our planet. … Healthy freshwater environments supply water for drinking, growing crops, manufacturing, energy and transport. They also help to prevent erosion, dispose of waste and provide natural protection from flooding. But we’ve been careless with this vital resource.
Why is freshwater so limited?
Freshwater is limited by high demand.
As population and industries grow, the demand for water becomes too high, which results in water scarcity. The cycle between water use and waste treatment shortens the more water we use. The faster we use water, the faster we must recycle it.
