Comments p.3/10 bottom paragraph:"[Investigators] utilised data on DNA concentrations in soil and water to achieve a much coarser-grained global estimate of the quantity of DNA in the environment. The quantity of dissolved DNA in aquatic environments is of the order of 10 µg/l [primary source] and the total volume of aquatic habitats on Earth is 1.4 × 10^21 l [refs 5,27], giving a total quantity of DNA of approximately 1.4 × 10^31 Mb."
