- 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.
