How much longer will earth have water?

Answer 1

That's almost impossible to precisely tell, virtually anything could happen! For the human race to consume all of the water on the Earth would take a long long long time! The sun would probably consume the Earth by then which is estimated to happen in six billion years.

Answer 2

It is estimated that the Earth will have water for billions of years to come. However, the availability of clean and drinkable water for human consumption is currently under threat due to pollution, climate change, and overuse of freshwater resources. It is important for us to manage and protect our water sources to ensure sustainability for future generations.
