There is always this fear that water levels are slowly going to rise and flood major areas of the world. There is also this fear that one day we are going to enter an emergency situation and not have enough fresh drinking water for everyone.

.......so why not just process ocean water and drink that which will help ease the rising water levels. I know we can do it we would just have to put the water through a strict filtration process (maybe even distill it) and we would have solved two of the more pressing problems of the near future.

Salt dissolves very easily in water, forming strong chemical bonds, and those bonds are difficult to break. Energy and the technology to desalinate water are both expensive. Also, it doesn't work that well. Also, we do do this is some places.

from what i remember its really expensive to do desalinate water

yup, that just about covers it. 5 star post.

there is more water in the air of this planet than there is in its oceans

98% of the Earth's water is contained within the oceans....

We already desalinate water, but it is horribly inefficient in cost and energy. We are going to run out of fresh drinking water very soon, it's already started in the poorer parts of the world. The US government has a map of the US color coded to how likely conflict is to erupt in the next 10 years over water. We're quickly approaching a population breaking point.

I'm almost positive that isn't true.

Yeah, no kidding. I live in fucking Arizona, we're pretty much guaranteed conflict and phoenix is still growing like the piece of shit conservative republican assholes that they are. We (and most other places) are pumping our aquifers at fifteen times the rate at which they are being restored and in doing so drying the climate so that the soil doesn't absorb rain water as well.

Ha, when I was looking for an image to go with the lawn post, I looked first for lawns in Phoenix as they are one of the silliest examples of water use. It now occurs to me I should have tried somewhere like Scottsdale. I'm not from AZ, but I'm pretty surprised at the amount of greenery when I visit.

(Incidentally, the image I posted is of artificial turf.)
