Desalination- viable?

Lets discuss a topic that was brought up to me. Desalination.

97% of the Earth's water is Salt Water. Unusable for our purposes. The other 3% is rapidly being polluted or used so fast that our aquifers and ground water can not recharge quick enough. Logically, we look into how to use the other 97% of the earth's water.

Desalination is a process that takes ocean water and removes the salt to make it drinkable. Many companies have already invested in this process as a viable way to ensure water is being provided. The process works, but it comes with some drawbacks.

De-sal is a very energy consuming business. It requires a lot of electricity which is supplied in terms of coal and oil. The efficiency of the process is very low, so economically this process may be very expensive. If we begin doing desalination, the greenhouse gas rates in the atmosphere will rise with burning of more fossil fuels to supply this process.

Now, a much better and cheaper option in my opinion is to just TAKE CARE of the water we already have. Lets conserve our resources and preserve the lifeblood of our planet. Practicing good management of land and water will ensure that our children will have safe drinking water without fear of it running out.
