A Modest Proposal For Water Conservation

Growing Population, climate change, increasing water demands, drought, and impaired water quality render water supply a critical issue across the world. More than 1 in 9 people around the world, about 750 million, do not have access to safe, clean drinking water, and the problem is expected to worsen.
In many parts of the world, water use is linked to energy use and greenhouse gas (GHG) emissions (any gaseous compound in the atmosphere capable of absorbing infrared radiation, thereby trapping heat in the atmosphere ultimately leading to global warming) because most water is transported hundreds of miles from sources to users.
According to a study by the UCLA Fielding School of Public Health, published online March 17 in the American Journal …show more content…

(2) Air-pollution-related illness and death. (3) Increased morbidity and mortality associated with sea-level rise and wildfires. (4) Food and water shortages related to increasing temperatures, changes in precipitation patterns, and increased frequency of extreme weather events. (5) Increased temperatures result in more rain instead of snow causing snow to melt earlier thus reducing mountain snowpack, which serves as a natural storage system for fresh …show more content…

1) Irrigation bans and 2) expanded use of recycled water
Irrigation Bans with increased use of local groundwater extraction and desalination can help meet urban water demands but requires a lot of energy thus more greenhouse emissions. Therefore expanded use of recycled water stood out as the water conservation strategy with potential to reduce water use, energy use, and greenhouse gas emissions, with relatively small negative impacts for the public’s health. Increasing the percentage of recycled water used would substantially decrease GHG emissions, which would have a dramatic positive impact on human health.
According to the study, if just 10% of the water that is currently imported from the State Water Project were shifted to recycled water, California would save approximately 80 million kWh of energy annually and reduce carbon emissions by nearly 42 000 metric tons per
