SVALBARD, Norway - It lies deep inside a mountain on a remote island between Norway and the North Pole, yet the Global Seed Vault in Svalbard is known worldwide.

That's where we find Sven on the next leg of his Arctic adventure.

"[The seed vault has] become infamous in the last decade or so because this is the place where if we really screw things up, we kind of can press the reset button," Sven explained. "This is where a lot of the world's seeds, the source of our food, would have to be restarted from."

The Global Seed Vault has the capacity to store 4.5 million varieties of crops. Currently, it has more than 890,000 samples from almost every country in the world.

The reason Svalbard was chosen for the seed vault is because the vault could be built deep into the permafrost, where seeds can be preserved, according to Sven. Svalbard is also the furthest north someone can fly on a schedule flight, making it remote but also accessible.

"An intricate system was designed so that even if everything fails, it would take years for that seed vault to get above freezing, so those seeds would be safe," Sven said.

After his stop at the seed vault, Sven hopped in a boat to head to the 80th Parallel in the High Arctic. Keep following his journey on Instagram here.
