The southern ocean is full of life and its productivity gives important information about climate change. Penguin populations depending on krill, the foundation of the food chain and the most abundant species on the planet, are declining. Animal population gives important insight on what is happening on a global level. Some changes are impossible to measure, far behind knowledge and should be our deepest concern.
Antarctica shows us what the future might be for us humans as climate change proceeds. We depend on proteins, from plants and animals. Environmental organizations like Greenpeace are focussing now on the ocean as a whole. They are pushing for a Global Ocean Treaty, a full protection of the oceans.
Carbon dioxide has never been as high in the atmosphere as it is now, above 400 parts per million. Last time this happened three million years ago. The consequences are far from our understanding. The southern ocean and its animals can give us important information so that we can try to act before it is too late. Climate change is happening and it is happening right now - it depends on us how the future will look like.
