- It is the process by which scrap aluminium can be reused in products after its initial production.
- The process involves simply re-melting the metal, which is far less expensive and energy intensive than creating new aluminium through the electrolysis
- Recycling scrap aluminium requires only 5% of the energy used to make new aluminium and releases a mere 5% of greenhouse gases.

2. Solutions to tackle problem of habitat destruction.
Areas like the Marine Protected Areas (MPAs) and Marine Reserves are established to protect habitats by prohibiting mineral extraction, fishing, etc in certain areas. One example of MPA is the NOAA National Marine Sanctuaries in USA. Marine Reserves are also found in countries like New Zealand.
3. Problem of soil erosion.
One way is to maintain a vegetation cover as the roots are able to hold on to the soil firmly.
Terracing is an extremely effective means of erosion control as the soil will not get washed down the slope easily. It is practiced in places like Sa Pa, Vietnam.

4 The problem of water pollution
- Many laws have been created to restrict industries from dumping materials into the water.
- For example, in the United States, the Clean Water Act was written to completely put an end to all dumping of pollutants into water.
- The law has not been that effective in many areas, but in other locations, it has achieved its goals.
