Roughly 97 percent of the water in the world is saltwater, and the salt makes the water completely unsuitable for human needs. Approximately 2 percent of the freshwater on Earth is in the form of glaciers and ice caps. That leaves only 1 percent of the Earth's water supply available for use.

Humans have the same amount of water now as when the Earth was created. As the world's population grows and temperatures become warmer, which causes evaporation, the water supply may become dangerously low. Freshwater is being used up faster than the Earth's water cycle can replenish it.

To help conserve water, people have to start using less. For everyone to do their parts, it helps to check faucets for leaks, only run the dishwasher and washing machine when they're full, install a low-flush toilet and install a low-flow shower head. Turning off the faucet while brushing one's teeth and shaving and taking shorter showers also make a difference.
