THE ALTERNATIVE??

Well, we could use something to condense the water vapour in the air, or in factories. However, the setbacks would be that the air that surrounds us would be dry. There will be no rain, and the whole world would become a desert. However, the amount of water that would be collected would be huge as the trees around us would transpire. This method will force us to conserve trees, thus killing two birds with one stone.
How does the device works? The device would suck in the water vapour in the air and converts it into liquid water in the device itself. The device would use some of the water that it makes to cool itself down. There would be no need to use more water to cool the water down. This can cut down the usage of precious water, which can actually be used for ourselves, instead of using it for industrial purposes. A lot of water is used up for industrial purposes, to cool down parts of the factories.
