The last part of the year will be spent exploring the oceans. Starting with how the oceans formed we'll move forward in time and talk about how they have changed throughout history. We know that ocean water is different than fresh water and that drinking it is unsafe, but why is that? We'll look at the charateristics of this water and how it has evolved over the years and how changes in global climates can drastically change circulation conditions. Finally, we'll look at the oceans as a resource of food and a possible futuristic energy source and try to predict the evolution of each.
