Water that could reach consumers disappears along the way and rivers are polluted

Two separate studies proved once again about the scandal of the management of water resources in many countries of the world, when proper management can provide water for the growing population

Groundwater

A long time ago I introduced you The water problem in our world. Over the years, hydrologists and environmentalists have been concerned with the wasteful use of one of the most important and essential resources for the entire world... and for humanity, a survey is now being published that shows how the wasteful use depletes the groundwater reserves (water-bearing layers - aquifer) worldwide and puts the existence of billions of people in danger.

The survey shows that: The use of groundwater in the entire world has doubled in the last decades, according to the study led by Marc Blerkens from Utrecht University (Netherlands) Marc Blerkens / Netherlands' Utrecht University The use of groundwater is becoming wasteful mainly because of transportation methods, water leaks from water carriers in huge quantities , water evaporates (on the way) between the wells and the consumers, water is wasted in wasteful irrigation, of course the global system is closed and therefore the amounts of wasted water reach the oceans, according to the researcher the amounts are so large that they cause a... 25% rise in sea level.

The global use of water is about 55 trillion cubic meters, the expectation is that by 2030 an additional 7 trillion cubic meters will be needed, an increase of about 40%, far above the supply capacity today. One of the main reasons for the wasteful use is... the explosion of the population, when population growth relies on the use of groundwater from reservoirs that are not filled and renewed... a "broken/empty trough" is reached, a situation arises in which the lack of water will cause hunger which will cause "social unrest"... in other words Riots on a global scale.

The areas where the problem was identified in all its acuteness are: Northwest India, Northeast China, Northern Pakistan, California, the Midwest in America

rivers

At the same time, a survey is published (in Nature) that warns about the sad state of rivers in the world. Rivers are the largest renewable source of water, water that is a source of life for the natural environment and for people alike, industrial pollution and domestic sewage, the construction of dams, the conversion of wetlands and wetlands into agricultural areas, the pollution of agricultural areas, the breeding of invasive species, all these and other hazards constitute a serious harm to the rivers of the world , an injury that endangers thousands of species of animals and plants in the aquatic environment and leads to their extinction.

Survey team leader Peter B. McIntyre professor of zoology at the University of Wisconsin-Madison's Center for Limnology. Says that: "Rivers all over the world are in a serious crisis". This is the first comprehensive (global) survey that examines the effect of water quality in rivers on the diversity of life and people. About 80% of the world's population is in areas where the rivers are sick. For thousands of years people have influenced water sources in general and rivers in particular, for thousands of years rivers have been a center of attraction, the dependence on rivers leads to various activities: agriculture, fishing, transport, damming and canalization.

When the activities are carried out without an environmental vision, irreparable damage is caused to the rivers. It turns out that rivers in different parts of the world are subject to similar pressures, some of which are indirect, such as mercury pollution caused by the operation of coal-fired power plants or pollution from mines in the drainage basins.

In most cases, instead of treating the source of the problem, they treat the symptom - instead of preventing the pollution, the water is put through a purification process. One of the findings that amazed the reviewers was the fact that despite years of activity to prevent harm, despite huge investments in attempts to improve water quality, most rivers in the "developed world" still contaminated.

Rivers in the USA and Europe are polluted in a way that endangers their environment and those who use the water. Instead of treating the sources of damage, instead of treating the pollution, huge sums are invested in water purification and the recovery of a sick environment. According to the reviewers: "The significant conclusion is that the "developing" countries must learn from the mistakes of the "developed" countries, investing resources in protecting and preserving drainage basins, preventing water pollution at sources and properly treating swamps and wetlands, will prevent the need to invest many times more in treating sick rivers.

Another and expected conclusion is that rivers in less populated areas such as inaccessible equatorial forests or rivers in the Arctic Circle... are the healthiest. The survey data were placed in a computer model so that any interested party can perfect them for any geographical area to draw conclusions and requirements and act on them to preserve the health of rivers wherever they are. And what about us?

Finally, an idea / suggestion:

Following on from the previous paragraph and following on from what I wrote about the Dead Sea in the past, everyone who passes by the factories is impressed by the smoke emitted from the chimneys... for the information of the "impressed", it is not smoke, it is water vapor, the raw material for the production of the minerals (carnelite) is "harvested" / drawn from ponds The evaporation, and the final drying is done in ovens in factories.

Although the figures below are not exact, the concentration of minerals in the Dead Sea (in the northern basin) is about 33%, assuming that after evaporation of water in the ponds, the raw material contains about 50% water, knowing that the factories produce about 5 million tons of minerals every year, the meaning of the data, some of which are based on estimates, is Because: every year about 5 million cubic meters of water go up in the chimneys!

That is: installing condensers on the chimneys will result in the production of 5 million cubic meters of clean (distilled) water every year... 5 million cubic meters of water. A fifth of the amount you will save by the national use of Shechems!
