Answer:
1.Water conservation: One of the most effective ways to ensure the continued supply of freshwater is to reduce the amount of water that is used and wasted. This can be done through a variety of methods, including fixing leaks, installing low-flow fixtures, and promoting water-saving behaviors among the population.
2.Water reclamation and reuse: Another way to ensure the continued supply of freshwater is to reclaim and reuse wastewater. This can be done by treating wastewater to remove impurities and then using the cleaned water for irrigation, industrial processes, or even for drinking in some cases. This not only reduces the demand for freshwater but also helps to conserve the existing water resources.
