How I can conserve water

I can save water by taking a shorter shower, this can save water by using and wasting less. I can also save water by biulding a solar powered bike, so I don't have to drink as much water. The only other way I can save water is to not to throw trash in water, if we ruin all of the water it will cost a lot of money and it might send the economy into a depression, forcing people to work even harder which means more water will be consumed and more water will be wasted on keeping us cool or being used to our food.
