Question

If we keep using water from seas, oceans, rivers, lakes will the water ever get finished?

Answer 1

If the population of living species including human keep on increaseing at a very rapid rate then we will be out of fresh water for sure someday. However, there is natural cycle through which water get replenished all the time. Water in seas, oceans, rivers, lakes etc get evaporated and then it comes back to earth in the form of rain water or snowfall which agai melts to give water. So, as long as the water sources are replenished, there be water in our seas, oceans, rivers, lakes etc in future.
