Our oceans contain almost 97% of the world’s water supply and play an important role in our water cycle, eventually giving us clean non-salinated drinking water. The water cycle involves the movement of water across different locations, through the processes of evaporation, condensation, freezing, and melting. It begins with our rivers which flow into our oceans. Water in the ocean then evaporates into the atmosphere. The water in the atmosphere condenses in the clouds. This condensation falls back to earth in the form of rain or snow, which replenishes the water supply in rivers, lakes and groundwater. Our drinking water may come from rivers and lakes, but the majority comes from groundwater. All of these are connected to the ocean through the evaporation and condensation process. If this process is hindered in any fashion, so is our supply of drinking water.
