What is the answer to the one who says: We do not need rain given the existence of desalination and water purification stations?

Question:
He says: Honorable Shaykh, may Allah grant you success, how do we answer the one who says that in this age we do not need rain because we have filters for salty seawater that turn it into fresh water?

Answer:
Yes, do the filters want to water the whole world? They do not water except a small group and a few houses. Then, these also cause the work of humans to be suspended and ruined. Also, these manufactured waters are not like groundwater or rainwater; they contain pleasure and health and the components of life. There is a great difference between healthy water, mineral water, and rainwater. Yes. Then, also, this healthy water or the water from the filters grows trees and grass and fills the wells.
Then, also, can all people afford to have filters? These require vast sums of money. If they become poor, how can they install these things? Yes.
