We can all play a part in improving our environment, whether we become more aware of recycling to educating our children about the importance of being environmentally conscious. Governments and city councils also have a responsibility and in this infographic, we can see that some of the greenest cities have been more serious about energy efficiency than others.
For example, in Copenhagen, you can see for yourself just how much they have embraced environmental responsibility whereby over one-third of residents use their bicycles regularly. In addition, there are many safe cycle paths that allow you to see the city plus get some fresh air. Closer to home, consider a visit to San Francisco where they encourage the use of electric cars, thereby helping to reduce smog.
