On my recent visit to Tomorrowland, I found that the world had indeed changed a lot since 2015. The world’s population had grown to over 9 billion people, and the demands on food production had doubled.
In 2015, seventy percent of the world’s freshwater was used for agriculture. But as the population grew and demands for resources became intensified in Tomorrowland, freshwater needed for drinking, hygiene, and culinary purposes stretched this finite resource to its limits, necessitating a reinventing and reimagineering of crop production and freshwater conservation.
The farmers in Tomorrowland have turned what used to be dry, desolate deserts into green, lush fields of green. How did they do it? By turning plentiful seawater into useable freshwater without the expensive desalinization process.
Using wind, fans, and simple evaporators, scientists found a cheap and easy way to convert seawater to freshwater and in the process create humid environments in which just about any plant could grow. By evaporating seawater inside expansive greenhouses and creating humid air that then condenses into fresh water for watering, they are using previously unusable salt water for agriculture and saved the world’s freshwater streams and lakes for drinking, hygiene and culinary purposes.
To meet the needs of Tomorrowland, we must invest in research and reimagine crop production to feed the world’s inhabitants. Two-thirds of the earth is covered in saltwater. We must find a way to utilize saltwater and desert lands for crop production.
