Saltwater is desalinated to produce potable water suitable for human consumption or irrigation. One by-product of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on the cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few rainfall-independent water sources.
This is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and re-vegetate disturbed soils in dry areas and during periods of less than average rainfall.
Sustainable energy is a principle in which human use of energy “meets the needs of the present without compromising the ability of future generations to meet their own needs.” Sustainable energy strategies generally have two pillars: cleaner methods of producing energy and energy conservation.
Water is a basic necessity and an important resource for sustaining life. The decline in water quality endangers the health of humans as well as the ecosystem. Clean drinking water, hygiene, and sanitation play an important part in maintaining health.
Diesel-powered vehicles and equipment account for nearly half of all nitrogen oxides (NOx) and more than two-thirds of all particulate matter (PM) emissions from US transportation sources.
