What are four reasons why the demand for water will probably increase in the future?

1) Polluted air will create changes in the atmosphere. Nothing can live without water and nothing will grow. Water is our life. It is worth more than gold and we should be more protective of what sustains life.

2) The ground water will become too toxic to drink from dumping cancer-causing toxic waste and pesticides into the field and streams. It never goes away. This might not seem like much but years of using banned pesticides, like Arsenic, seep into the soil. 200 years later Arsenic and heavy metals, are still in the soil. It is really bad in the Southern states where most of our rice comes from.

3) The atmosphere is burning away which will cause extreme global warming. Water will dry up faster in areas where drought is already a problem. People will constantly be on the move--always searching for water.

4) People and animals will have to relocate to areas where there is safe water. Those areas will be over crowded. Wars will be fought over water.

Why four?

increasing population, increasing industry, shrinking lakes and streams, something else.

3/4th's of the Earth's surface is covered with water, and water does not evaporate into space.

The Earth will never run out of water unless something takes it off the planet.
