Preventing Hazardous Waste Problems

Study Tip
Currently, countries like the United States and China produce the most hazardous waste. The Superfund Act in the United States requires companies to clean up contaminated sites.

Cause and Effect

  • When there is more industry in a country, more industrial waste is produced.
  • Cleaning up industrial waste is often expensive and harmful to the environment.
  • Since only large organizations can tackle this problem, the government is in charge of cleaning up hazardous waste.

Combating Hazardous Waste

  • Many countries have laws that manage the disposal of toxic waste, such as the Resource Conservation and Recovery Act of 1976, which requires companies to make a record of the toxic materials they produce.
  • People can also control the hazardous waste they use by properly using and disposing of cleaners, detergents, pesticides, and fertilizers.
