The Importance of Recycling
Mining and extraction of metals takes up a lot of energy – and often this energy is produced by the burning of fossil fuels. These fossil fuels are running out and when they are burnt they add to acid rain, global dimming and climate change.
Recycling uses much less energy (e.g. recycled copper only takes about 15% of the energy needed to extract new copper. It also saves lots of money!
Another benefit is that metal resources are limited – so recycling is really necessary!
Lastly recycling cuts down on the amount of waste produced. Landfills around the country take up loads of space and pollute their surrounding areas!
