Explanation:

1. Water affects human life in many ways. Specifically, a lack of clean water leads to disease and death. Ultimately, the ability to get fresh, clean water is vital to supporting the life of human beings.

2. causes of scarcity of water are:-

• Climate change.
• Natural calamities such as droughts and floods.
• Increased human consumption.
• Overuse and wastage of water.
• A global rise in freshwater demand.
• Overuse of aquifers and its consequent slow recharge.

3. There are two main sources of water: surface water and groundwater. Surface Water is found in lakes, rivers, and reservoirs. Groundwater lies under the surface of the land, where it travels through and fills openings in the rocks. The rocks that store and transmit groundwater are called aquifers.

4. The main purpose of the rainwater harvesting is to use the locally available rainwater to meet water requirements throughout the year without the need of huge capital expenditure. This would facilitate the availability of uncontaminated water for domestic, industrial, and irrigation needs.

5. Conserving water helps us by supplying more amount of water for longer usage. It has become necessary in all areas because these natural resources are reducing along with the increasing population and their usages. Keeping the tap closed when not in use.
