How can water , a renewable resource become a non renewable resource

Water can become a non-renewable resource if we contaminate all our rivers.

Explanation: For example, as groundwater is usually removed from an aquifer at a rate much greater than its very slow natural recharge, it is a considered non-renewable resource. Removal of water from the pore spaces in aquifers may cause permanent compaction (subsidence) that cannot be renewed.

AS BOTH RENEWABLE AND NON RENEWABLE

Water can be considered a renewable material when carefully controlled usage, treatment, and release are followed. If not, it would become a non-renewable resource at that location.

For example, as groundwater is usually removed from an aquifer at a rate much greater than its very slow natural recharge, it is a considered non-renewable resource.

Removal of water from the pore spaces in aquifers may cause permanent compaction (subsidence) that cannot be renewed. 97.5% of the water on the Earth is salt water, and 3% is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction (0.008%) present above ground or in the air.

Water is not replenished like most renewable resources and instead—reused. If we were constantly losing water, then the speed at which water forms wouldn't be very sustainable, and would then be considered a nonrenewable resource.

Potable, fresh water can become a non renewable resource if we contaminate all our water tables and rivers, which we are working on.

b. the carbon cycle ensures living things have a source of hydrogen

a "theory" a suggestion that is not 100 % accurate, or a figure. some people say its a theory because they of all the passed theory's about one subject. it depends sometimes theory might be accurate and sometimes they are.
