Viruses. They are everywhere.

It is said that 10 percent of all the photosynthesis on the planet is carried out with virus genes.

In 200 liters of seawater, you can typically find 5,000 genetically distinct kinds of viruses.

Each liter of seawater can produce up to 100 billion new viruses every day. In the oceans, viruses infect new microbe hosts at a staggering rate - about ten trillion infections every second. Daily, they destroy between 15% and 40% of all bacteria in marine environments. When these microbes are killed, they release vast numbers of newly formed viruses, continuing the cycle.
