Why was desalinization process developed in sw Asia?
Although at least two thirds of our planet is covered with water, less than 2% of it is drinkable. However, salt water can be made drinkable through desalinization and other filtering or processing.
How much water is there on earth today compared to 100 years ago?
there is still the same amount of water on earth as their was 100 years ago or in fact 1 million years ago. The fact is that today less water is in ice form then there was 100 years ago.
Is there an unlimited supply of fresh water?
No. The earth is 70% water, and less than 1% of that is drinkable. The earth doesn't "Make" water as fast as we need it, and we can't purify the seas.
How low must the salinity of water be before it's drinkable?
Fresh water typically has a saline content of less than 0.5 parts per thousand, brackish water 0.5-30, and saltwater 30-50
How much of earths total water supply is not available for drinking water?
0.03%
Is the conversion of salty water or ocean water to pure water successful for human beings?
There's no problem making sea water fit to drink, but there is a problem doing it cheaply enough. If there is freshwater around, it's usually less expensive to process that into drinkable water.
What do you use when you want to separate salt from water without the water evaporating?
Ocean survival kits once used a chemical that would bind to the salt and sink to the bottom of a container. The less-salty water at the top of the container would be drinkable. Life rafts today may carry "reverse osmosis pumps" that force seawater through a permeable membrane to separate out the salt.
How does the atmosphere composition today compare with the air 1000 years ago?
1000 years ago the air was much the same as it is today, with a little less CO2 and a little less pollution.
In a survival situation what is more important than food?
Water is even more important than food in a survival situation. Clean, drinkable water can keep you alive for weeks, whereas without water you will perish within a few days (or less, in a harsh, dry, hot climate).
What is the percentage of freshwater out of the worlds total water?
Most of the water on Earth is undrinkable, about 99%, only 1% of the water on Earth is drinkable, and only half of that is easily available!
How much did gas cost five years ago?
Quite a bit less then today.
How much of earths water is drinkable?
71% of the world is covered with water, but the oceans are so deep, 97% of the water on Earth is salt water. Of the remaining 3%, about 2% is in glaciers or otherwise unattainable. About 1% of Earth's water is drinkable quality found mostly in fresh ground water.
