An explanation of the scope of the problem, from the article: "The roughly 2000 sequencing instruments in labs and hospitals around the world can collectively generate about 15 petabytes of compressed genetic data each year. To put this into perspective, if you were to write this data onto standard DVDs, the resulting stack would be more than 2 miles tall. And with sequencing capacity increasing at a rate of around three- to fivefold per year, next year the stack would be around 6 to 10 miles tall. At this rate, within the next five years the stack of DVDs could reach higher than the orbit of the International Space Station."
