It Is A Bad Idea If mining companies start mining the hydrothermal vents down at the bottom of the ocean it could damage the ocean floor and the fragile ocean life, causing a species to be extinct which means we won’t be able to study and learn about them. Hydrothermal vent mining is a bad idea because it damages the ocean, ocean floor and the fragile ocean life. A hydrothermal vent is a chimney like structure that is made out of minerals like gold, silver, and copper, etc. Hydrothermal vents are found at a depth of 2000 meters which is approximately 2.42 miles. They are found at the ring of fire in the ocean, at tectonic plate boundaries and where water and maga mix. Because of the volcanic activity under the ocean it pushes up water
