  • Why are oceans important?
    • Climate regulation
      • Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
      • Ocean water is constantly evaporating
      • The ocean also helps to absorb Earth’s CO2.
      • Without these currents, the weather would be extreme in some regions, and fewer places would be habitable.
      • almost all rain that drops on land comes from the sea
      • Eg. Western Europe is warmed by the Gulf Stream
      • The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere.
    • They are our life support machine
    • less than 2% of the ocean is protected
    • 20% of coral reefs are gone
    • recreational opportunities
      • From fishing to boating to kayaking and whale watching, the ocean provides us with many unique activities.
      • When our face touches water, our heart rate immediately slows down, and blood moves from the extremities to the brain, heart and vital organs of our body
      • The ocean has therapeutic properties
      • Research has proven that the so-called blue spaces can directly reduce psychological stress and improve mood
    • Foodsource
      • many of the most commonly caught species - such as tuna, swordfish, herring, sardine, and anchovy - are also caught in the open ocean
      • ingredients from the sea are found in surprising foods such as peanut butter and soymilk.
      • Seafood
      • the number one source of protein for more than a billion people
      • Humans have traditionally used algae and sea plants for cooking
      • we are relying on the ocean more and more for survival
    • Economic benefits
      • ocean-dependant businesses employ almost three million people.
      • 59.6 million people in the world were engaged in fisheries and aquaculture in 2016.
      • The ocean gives jobs to fishers, lifeguards, surf instructors, harbours, (free)diving schools, marine-based tour operators, water sports business, holiday accommodations,
    • Transportation
      • oceans provide convenient transport routes -
      • 90% of world trade is made by sea
      • everything from food and fuel to construction materials, chemicals, and household items is transported
