Many nations use oceans to drill for oil which is a non-renewable resource that often damages the ocean and can cause major problems for the biome. This means also that more oil is used then so that's bad for the environment too. Sometimes there is an oil spill which kills many animals and plants that live in the ocean and cause a natural disaster. Even renewable resources from oceans like using water and dams to make electricity can be problematic because the water gets polluted. It would be best if countries switched to things like solar energy and wind energy.
