Why are landfills bad? Use comparison between landfills and the other 2 waste management methods in your answer. [3]
- Bad for local environment: Biodiversity within region may be stunted due to mass-clearing of land and the introduction of harmful substances into ecosystem.

- Ineffecient land usage: Landfill sites cannot be used for other purposes like developing infrastructure or growing crops for the growing population.
