Harvesting Timber Underwater

A company in Canada has developed a submersible that has a chainsaw and can cut down trees that are underwater. This means it can harvest trees that are underwater in lakes that were created when valley floors were flooded behind hydroelectric dams. Because the trees are in cool water with a lack of oxygen, they have been preserved from decay. It's been estimated there are 200 billion board-feet of high-quality timber down there. That's more than six times the amount harvested each year in the US. What a great way to save live trees!
