Key Topics to Revise

1

Introduction to Pollution Prevention

  • Pollution is the contamination of air, soil, or water by discharge of harmful substances.
  • Pollution prevention = reduction or elimination of pollution at the source.
  • Prevention involves: efficient use of raw materials, water, and energy; substituting less harmful substances for hazardous ones; eliminating toxic substances from production.
2

Carpooling

  • Carpooling (also called car sharing, ride sharing, lift sharing, or covoiturage) is the sharing of car journeys so that more than one person travels in a car.
  • Benefits for individuals: reduces each person's travel costs, tolls, and stress of driving.
  • Environmental benefits: reduces carbon emissions, decreases traffic congestion, and lowers the need for parking spaces.
3

Promotion of Public Transport

  • Public transport offers alternative modes of transport to private vehicles.
  • Types of public transport: trains, trams, and buses.
  • Public transport can relieve traffic congestion and reduce air pollution from road transport.
4

No Smoking Zones

  • Smoking bans (smokefree laws) are public policies including criminal laws and occupational safety regulations that prohibit tobacco smoking in workplaces and public spaces.
  • Core rationale: smoking is optional, but breathing is not — hence non-smokers must be protected.
  • Passive smoking (inhaling second-hand smoke) causes: increased risk of heart disease, cancer, and emphysema.
