is rapidly becoming a very scarce commodity. The dehydrating planet is in the grip of an oil crisis.... LOL, no, not your energy crisis, but the marine micro-layer oil membrane crisis.
Ice clouds are now being seen around the equator.... and the lands are baking, burning and slowly turning to dust........ and earthlings still drive their extinction inducing automobiles as if nothing is happening..... LOL... welcome to the race.... to extinction...earthlings!!!!!!
LOL

Few commentators specifically mention the declining availability of water that is needed to grow irrigated and rainfed crops. According to some, the often mooted solution to the food crisis lies in plant breeding that produces the ultimate high yielding, low water- consuming crops. While this solution is important, it will fail unless attention is paid to where the water for all food, fibre and energy crops is going to come from.
The causes of water scarcity are essentially identical to those of the food crisis. There are serious and extremely worrying factors that indicate water supplies are steadily being used up. Essentially every calorie of food requires a liter of water to produce it. Thus those of us on western diets, use about 2500-3000 liters per day. A further 2.5 billion people by 2030 will mean that we have to find over 2000 more cubic kilometers of fresh water to feed them. This is not any easy task given that current water usage for food production is 7500 cubic kilometers and supplies are scarce.
According to the recent report "Water for Food, Water for Life" of the Comprehensive Assessment of Water Management in Agriculture, which drew on the work of 700 scientists, unless we change the way we use water and increase "water productivity" (i.e. more crop per drop) we will not have enough water to feed the world's growing population (This population is estimated to increase from 6 billion now to about 8.5 billion in 25 years.) Compared with the lengthy agenda to combat climate change, this is a very short time indeed and yet the impacts of water scarcity will be profound. However, very little is being done about it in most countries.
Current estimates indicate that we will not have enough water to feed ourselves in 25 years time, by when the current food crisis may turn into a perpetual crisis. Just as in other areas of agricultural research and development, investment in the provision and better management of water resources has declined steadily since the green revolution. I and my water science colleagues are raising a warning flag that significant investment in both R&D and water infrastructure development are needed, if dire consequences are to be avoided.

conservative estimates... fires will devastate the countries long before then
and earthlings will destroy each other...... nice stuff to watch from afar.
