Give three reasons why it is necessary to conserve water in Namibia.

Water is a precious resource, particularly for an arid country like Namibia. Unfortunately, the large amount of water used by households has a significant environmental impact, so saving water means protecting the environment and sustaining our long-term development.

Explanation:

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
