earth's water cycle gives us fresh water. we use this fresh water for our daily consumption. when this water cycle is in danger ,our fresh water source also comes in danger. thus if any disturbances occur in the earth's water cycle ,these disturbances directly or indirectly affect our water supply. for example if an area's water supply depends upon a river's fresh water and if due to acid rain the water of that river gets contaminated then the water supply becomes contaminated and cannot be used.
