- - - - By relying on gravity, e.g. the use of wheels
  - - - Not always. Many modern materials, such as plastic, are bad for the environment as they are often made for single use (to be disposed of only after one use, for convenience) and take many years to decompose.
  - - - Helicopters | a type of leaf that swirls like a helicopter fan
      - Submarines | fish
      - Airplanes | birds
      - Boats | floating sea animals (?)
    - - Skateboards
      - Heely's (shoes with wheels at the bottom/back)
      - Rollerskates/rollerblades
      - Scooters
      - Ice skates
      - Bikes
- - - - In comparison to Singapore, Tokyo, Seoul, Shenzhen and Guangzhou, Hong Kong is not as on track with using renewable energy and other methods of minimising greenhouse gas emissions
    - - The goal for HK was to reduce the carbon emissions per capita to under 4.5 tonnes per year by 2020
      - Reduce to 3.3 to 3.8 tonnes per capita per year by 2030; 10 years from now.
  - - - Public transport
        
        Boats & ships
        
        MTR
        
        Buses
        
        Trams
      - Private transport - taxi, car
      - Minimal energy transport
        
        Wheels - rollerskates, skates, scooters, skateboards, bikes
    - - Lights (lightbulbs are the most inefficient use of energy - most of it turns into heat which is released from the lightbulb and dissipates into the air).
      - Cooking (electricity/gas)
      - Industrial use
      - Heated water (towngas)
      - Electronic devices
- - - - 7% of children don't exercise apart from in PHE classes
      - Only 30% of HK students spend time with their family doing physical activities weekly, also under the recommended average.
    - - Heart disease
      - Type 2 diabetes
      - Moderate (low-medium intensity exercise frequently) exercise at a young age will prevent these diseases from occurring later in life
        
        Improve metabolism and heart health
    - - Promote social inclusion for different backgrounds, ethnicities, sexual orientation, skill levels, physicality and more.
      - Strengthen relationships with others: parents, coaches, friends
      - Physical activity can improve young people's brain development
      - Frequent exercise can boost brain power and academic performance for people 6-18 years of age
      - Immediate positive effects on brain function and one's academic potential
      - May improve grades (taking class time for exercise doesn't cause grades to deteriorate)
        
        Improving one's mental health (by having a side hobby, doing exercise they like) can also benefit one's academic success
    - - Providing equitable access to public spaces for exercise - cycle lanes, parks, playgrounds
    - - Only 21-40% of the HK population meets the international standard for physical activity
      - Roughly 80% of youth travel to school on foot / via bicycle
      - Most young people were satisfied with the provided sports facilities by the government.
