Many supermarket vegetables are already grown hydroponically in nutrient-enriched water, and research indicates this technique could work well in space.
That means building futuristic structures that use wastewater and solar power to produce hydroponic (grown in a nutrient-rich water, without soil) and aeroponic (grown in water-saturated air) crops.
Hydroponics and aeroponics - a type of hydroponics, but rather than growing in nutrient-rich water, grows in the air and the plants get sprayed with nutrients - technology is increasingly being utilised by businesses themselves.
By looking at which creatures flourish in their mesocosms, Ulf Riebesell of the Leibniz Institute for Marine Studies in Kiel and his colleagues hope to see changes as they take place by keeping an eye on the water chemistry and nutrient levels.
Effluent waste from these concentrated animal facilities are undermining what little clean water and healthy micro-nutrient cycles still exist out there.
It also ignores the considerable value of services derived from the physical, biological, and chemical processes in natural ecosystems, including nutrient recycling, flood risk reduction, water cleaning and storage, climate regulation, and maintenance of biodiversity.

The development of biofertilization techniques would also increase water use efficiency by promoting higher nutrient absorption and crop growth rates.
Biodiversity, which includes species, ecosystems, and ecological processes, is essential for the long-term maintenance of ecosystem services like photosynthesis, nutrient recycling, soil fertility, provision of fresh water, disaster prevention, and many others.

Nutrient overloads lead to low levels of dissolved oxygen in the water, which can kill fish.
This nutrient enrichment damages aquatic life there too, and degrades drinking water.
In the ancient oceans, green rust's ability to pull nickel out of the water would have been critical for some life forms, since nickel is an important nutrient for microbes that produce methane.
The idea is to experiment with projects that pay farmers to reduce nutrient pollution, using money that would otherwise have been spent on expensive technology for use by institutions such as municipal water authorities.
