  • Threats to the Oceans
    • Whaling
      • Whales have been protected since the 1980's yet some countries use loop holes to continue.
      • Japan kill 850 Minke Whales a year in the name of scientific resaerch
        • South Korea shocked the international community by announcing it would start ‘scientific’ whaling
    • Overfishing
      • Entire populations of fish are being targeted and destroyed, disrupting the food chain from top to bottom. Overfishing happens when the amount of fish caught exceeds the amount of fish needed to sustain fish stocks in a given region.
    • Bottom Trawling
      • Deep under the ocean, Biologists estimate that somewhere between 500,000 and 5,000,000 marine species have yet to be discovered.
        • Many of these species are in serious danger from the world's most destructive fishing practice - bottom trawling.
    • Climate Change
      • The ocean absorbs 80% of all the heat added to the Earth due to climate change.
        • Warmer waters cause coral bleaching which negatively impacts the whole coral ecosystem
      • As more fossil fuels are burnt, the acidity of the oceans increases.
    • Aquaculture
      • Fish frams destroy habitats for use of their room and nutrient rich water
      • Anti-biotics and chemicals used to fight diseas can cause harm to the surrounding fish and the people who eat them
  • Whales have been protected since the 1980's yet some countries use loop holes to continue.
