Earth’s oceans are the womb of all life on Earth. Healthy oceans are rich in beauty, wildlife, and indispensable ecological services. But lack of governance and a corresponding wild west mentality are rapidly degrading the vast waters upon which all life depend.

Marine's Ecology

It’s easy to regard oceans as a set of biologically necessary life-support processes. The ocean produces 50% of all oxygen on Earth, everyday it feeds over a billion people, and it is the largest carbon. But the ocean is more than an engine for life; it is the source of life. And just as we do not regard a mother in terms of her instrumentality, so too is the ocean an entity in possession of innate value and worthy of deep and enduring respect.
