around these drowned logs. These logs provide substantial structural support for these ecosystems, and removing them would inevitably destroy said natural habitats. Boats and crew members of underwater logging fleets can stir up and degrade the local ecosystems. Sustainability Nature & Faune magazine describes the process of underwater logging's sustainability impact. The hydroelectric dam in Ghana built in Akosombo submerges forests of timber logs. The Clark Sustainable Resource Developments uses SHARC ROV technology to keep the roots of the trees intact not to disturb the lake bottom or disturb pollutants. After, they put canopies and buttresses to create artificial fish reefs and educated locals about fishing practices. Lastly, they can cut up to below the lakes surface, which creates a depth sufficient to support routes for transportation lake vessels. This process was awarded for being sustainable by avoiding deforestation and making artificial reefs to maintain the current aquatic ecosystem.
