ted to irrigate cotton, and the sea can no longer be sustained. As a result the twenty-four species of fish that were once thought to live there are all thought to be extinct. Human habitats are ruined when they have to be relocated due to the making of a reservoirs or building of a dam. Numbers of people ranging in the tens of millions have had to leave their homes, because of where their country chose to create a new water source. Most had no warning that they were to leave and they were never provided any compensation for their loses. The question that many ask is how can it be possible for a planet whose surface is covered mostly by water face a lack of water. The fact of the matter is that more than 90 percent of the worlds water is too salty for humans to utilize. Of the two percent that is consumable half of it is unreachable. Frozen in ice caps and glaciers or deep underground where we cannot take advantage of it. There is one process that enables us to take advantage of our salt water called desalinization. This process is very expensive, time consuming, and difficult. Huge plants must be constructed, and can sometimes be harmful to the environments around them. The process consists of turning salt water into steam and filtering it. Once that is completed it is evaporated again and cooled once more. After purification and more filtering freshwater is created, and you are able to drink it. Experts make predictions and estimations are made but no one really knows how our water supply will be effected in the future and what will happen if we cannot sustain it. Efforts are being made and calculations are being taken but unless everyone pitches in and helps we will be lost. If we learn how to evenly distribute and how to control flow enough so that no one will be without necessary sanitation and drinking water that will just be the beginning. After that we must learn how to preserve our water, and find out how we can make it last...
