In celebration the 2020 Earth Day, the topic of fresh water has become a bigger discussion for the next challenge. A breathtaking 70 percent of the world’s fresh water is currently used for producing crops and raising livestock. Competition for that life-giving resource is only set to increase in the future, as fresh water becomes scarcer in much of the world due to drought and saltwater encroachment in coastal areas. A report released by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) in September warns that sea levels are very likely to rise between 2- and 3.6-feet by 2100 (but the rise could be much higher, to as much as 6.5 feet, should the Antarctic ice melt faster than predicted)
The article "How algae could help save us from the impending freshwater crisis" on the Massive Science of Rachel Nuwer tells the story of the micro-algae farm in New Mexico, where the micro-algae Nannochloropsis is cultivated, this farm is a part of iWi Company. The farm is located in the New Mexico dessert and has a very high water usage efficiency. About 95 to 97 % of the water is recycled.
Working on a different approach to the same goal of saving water, the DQS team is proudly doing its part to develop the cultivation methods for Spirulina, which is another high-nutrition micro-algae. We believe the micro-algae is much needed for the humanity future.
