One by one, the Earth’s natural resources are disappearing. And by no means is fresh water safe from elimination. And in a world where most living things only thrive on fresh water, the search for an alternative is rising to the top of the science community’s list of priorities.

98% of the water on Earth is from the ocean. So it only makes sense that scientist have been looking to the ocean as the next frontier for survival. Plants such as kale and samphire can be cultivated in salt water, as they have been for several thousand years by our ancestors. Spinach and beetroot are also options for the salt water revolution. At this rate, soylent green is no longer something we have to look forward to.
