Nature has been using this method of storing information for billions of years. Humans are just learning it. It sounds incredible, but a single DNA macromolecule can store an enormous amount of data with great accuracy and virtually unlimited lifespan. To put it in perspective: the annual production of digital data worldwide would fit into just a few grams of DNA. A team of scientists from the European Bioinformatics Institute (EBI) led by Dr. Nick Goldman managed to encode all 154 of Shakespeare's sonnets, a 26-second video clip recording Martin Luther King's legendary "I have a dream" speech from 1963, the groundbreaking scientific article by James Watson and Francis Crick about the discovery of DNA structure, and a photograph of the EBI headquarters building facade in Hinxton, England, into synthetic DNA. 
So will synthetic DNA become the mega-storage for data and information from around the world in the future, as their volume grows year after year? The method to make this happen exists, but it will also depend on the costs that the entire process will require. You can learn more in the video here. Whatever the case, we at Greenhousing will need to look for capable biologists so we don't fall behind in development.
