Since the oceans cover 70% of the globe, any change to the ocean system will affect the rest of the global system. In addition to their large influence on climate, the oceans have been nicknamed the "Lungs of the Earth."

Studies suggest that approximately 70% of atmospheric oxygen comes from marine photosynthesizers, many of which are invisible to the naked eye. In general, marine algae only have two environmental requirements: seawater and light. Therefore, these macro and microscopic algae have shown great plasticity and can occupy a wide variety of habitats. Fortunately, these essential organisms have a good chance of surviving and adapting to future changes.
