Ocean acidification is a growing problem that affects global environment. Its effects are detectable now, putting the most extensive water resource on the planet at risk and influencing the climate changes that can be documented across the globe. This paper analyzes the protection of the sea as a measure to ensure a healthy environment for future generations, guaranteeing a better way of life for them. We present the different principles governing bioethics, and we establish their relationship with the processes of sustainable development and the increase of acidification in the ocean, which affects a large number of communities of scarce resources in the world.
