Half of the planet’s population lives in cities, yet they consume 75% of the world’s resources and create most of their pollution. This means that all governments are going to have to create effective recycling plans. In cities where recycling schemes have been successful, it is possible to recycle 95% of all household waste. It takes 30 – 40% less energy to make paper from recycled materials than it does to make it from trees. Statistics show that there is a growing awareness of the importance of recycling, and countries such as Sweden already recycle much of their waste.
As the burning of fossil fuel is a major cause of pollution we will have to turn to other energy sources and what could be a better source than the sun?
