“Water memory” is the idea that water may remember things that have been dissolved in it in the past, even after any number of successive dilutions.
Africa is one of the world’s most water-scarce regions, with some countries facing chronic water shortages. But in the last decade, countries in the region have embarked on an unprecedented number of large-scale water projects, in an attempt to overcome their water constraints. The result has been a boom in water infrastructure in Africa, including dams, pipelines, and groundwater extraction wells. This unprecedented expansion of water infrastructure has brought with it a series of environmental, social, and economic impacts.
Global warming is one of the biggest problems facing humans today. Over the past century, the Earth’s average temperature has risen by about two degrees Fahrenheit, causing environmental changes such as melting icecaps and glaciers, rising sea levels, and changes in the weather.
Trees produce the oxygen we breathe, filter the air we breathe and provide homes for countless wildlife species. But trees also provide countless other benefits that are often overlooked, from preventing soil erosion to providing shade and shelter.
Water vapor can be stored and released by the layers of the forest canopy, branches, and roots, which influences rainfall. They can also help to mitigate the effects of storm-related flooding by blocking and reducing the flow of runoff.
