Waste management (4.7.3.2) — AQA GCSE Biology Revision Notes

Revision notes for AQA GCSE Biology specification point 4.7.3.2, Waste management.

Escalating Waste Production

With more goods being produced for a increasing human population, there is also an increase in WASTE, including hazardous CHEMICALS.

If not managed properly, this waste can cause POLLUTION, which has harmful effects on plants and animals, and can severely reduce BIODIVERSITY.

Waste

Examples include:

  • INDUSTRIAL WASTE can pollute lakes and rivers and affect aquatic life.
  • AGRICULTURAL CHEMICALS, such as fertilisers and pesticides, may lead to water pollution if not managed properly.
  • SOLID WASTE management is becoming more challenging, with landfills filling up and the need for recycling becoming even more critical.
  • AIR POLLUTION from industrial emissions, including SMOKE and ACIDIC GASES, has global impacts such as ACID RAIN, which can damage ecosystems far from the pollution source.
